Task 1–Computer Systems
Internal System Unit Components:
Central processing unit
A processor or also known as a micro–processor is a small chip that goes inside a computer and
some other electronic devices. The job of a processor is very important as it has to receive input and
provide the appropriate output. This component can handle trillions of calculations per second.
The main processor in a computer system is called a central processing unit which handles all the
simple instructions that the computer gives. For example it gives instructions for processing output
features like the mouse and keyboard and running applications. The processor fits on the
motherboard and is known as the 'heart' of the computer system as it controls everything that takes
place in the computer system. The central processing unit contains the circuitry which processes the
instructions in the computer programs by interpreting them into actual movements of bits of data
within the computer memory. Motherboard
The motherboard is the most important component within a computer system. The motherboard is a
printed circuit board where the majority of the essential parts of the PC belongs. Connections
between the actual PC and peripherals go through the motherboard. The motherboard houses
components like the CPU, RAM and other hardware components. BIOS
The basic input/output system is a collection of software utilities that forms part of the operating
system. BIOS are built into a PC and are run

Computer Systems : Questions And Answers
1) A shell is a command window that executes what the user enters. Its a window where the user has
access to files, directories and everything on their computer. Shells have command lines where you
can type certain command which can do an operation such as create a file or folder, or print
information like the uptime of a system or file names in a folder. Their are multiple different shells
out there that you can use on a system such as bash, vi or even terminal.
2) To find out how long a system has been running, I would use the system uptime command in a
Linux or IOS machine. To do this I would go to the terminal window and type in the command
"uptime" on the line and press enter. That will print out the current time then the amount of ... Show

So for this example you would type "ssh charlieBrown@192.178.12.4" into the command line.
6) The root directory is the main directory of a unix based system. Basically all directories have a
parent directory and they all start with the root directory. The reason its called the root directory is
because its similar to a tree, it all starts at the root and goes to all the different branches that contain
twigs.
7) Linux distributions like Ubuntu and RedHat, are operating systems made by individual entities
that take all the pieces of a linux system, and puts it all in one place. When we download a
distribution like ubuntu, you're downloading an operating system that was put together by people
that chose what pieces of the linux puzzle they wanted to put together and how. Distribution can be
completely different from one another, some distributions can be used to run a desktop computer
similar to mac or windows device, some are used in hobby project like mini retro arcade machines
and some are used in servers. Three different applications which would need three different linux
distribution.
8) To create an empty file within the home directory you can use the touch command on the
command prompt. In this case the current working directory seams to be the home directory so all
that needs to be typed is "touch " followed by the filename you chose to name it.
9) Path information is basically the map to a file or folder. For example if I have a file on my

This report is produced in order to provide clients a basic compare between the two accounting
computer system, Excel and MYOB. By doing this, the customer could choose the best accounting
software depend on the business size and its features.
_The major difference between Excel and MYOB in accounting is that, Excel is a manual system;
mean the users must input all the transactions data manually in the Excel spread sheet. If the firms
have some credit transaction, double entry may be required. Then at the end of an accounting
period, the Excel users (owners) may provide the spread sheet to accountants or someone who have
accounting background to prepare BAS for the ATO or other financial reports for stakeholders.
Unlikely, MYOB or Mind Your Own Business is a specialist accounting software that designed for
small business and is probably the best known accounting software in Australia and New Zealand.
With MYOB the users only need to input the transaction information and the system will
automatically prepare the BAS, financial report and also bank reconciliation. Moreover, MYOB is a
more complex accounting computer system compare to Excel, since it provides different functions
that help the owner to manage their business; such as payroll, inventory,

Contemporary Information Security Systems And Computer...
According to identitytheft.info, almost 15 million Americans have their identity used fraudulently
due to information leaks and information insecurities. With the growing dependency on computer
systems to store confidential information across the world, it is only necessary that that the
information be protected by strong security systems which include both hardware and software so
that both the businesses and the consumers feel safe in the transportation of information over the
inter–webs. Contemporary Information security systems use many different components involving
both hardware and software
Primarily, User Access Control or UAC systems are combinations of identification, authentication,
and authorization that helps restrict users to what information they can access in a database system
with certain read and write rights. Most of the identification systems operate by using a simple serial
ID followed by an identity challenge such as a password (Blanding F. 2004). UAC is the most
fundamental access–control technology as without it, there cannot be further information systems.
Within the UAC system, the system administrator designates users rights and accesses which helps
develop the "login authentication" aspect. The system administrator is the primary local account that
authorized personnel can use to create system logins for users with certain privileges. It most cases,
the administrator is only responsible for creating the "username", often designated as the

We chose 64 Megabytes because this much power is required for an avid gamers graphics to run
quickly and efficiently, and appear crisp and clean. As well this amount possess enough power to
edit digital video well for his amateur needs. The NVIDIA card also has an s–video out which
allows the computer to connect to an extra monitor or a television. This card is capable of clone–
screening, horizontal split, and vertical split views. This provides upgrade options if our client
wanted to purchase another monitor later on and give him more workspace. This video card allows
up to a 2048x1536 pixel screen, but we recommend a 1280x1024 pixel range for great resolution,
easy reading and best performance.
NIC (Network Interface Card)
·We recommended a NIC instead of a modem because a modem would not be sufficient to meet this
gamer's high–speed online needs. Also a NIC allows for easy interfacing between other LANs
(Local Area Network) and WANs (Wide Area Network). This means that if our client wanted to he
could connect his computer to all of his friends' computers.
Monitor
·We recommended that our client invest in a :Hansol 720ED 17–inch CRT (Cathode Ray Tube) flat
screen monitor. This monitor is cheap, has excellent resolution and picture quality. Also this monitor
is much cheaper than the LCD (Liquid Crystal Display) monitors, which are currently available.

Mouse and Keyboard

And the 500GB hard drives on all of the laptops in this report are more than up to the task of storing
all of Sharon's music. To use internet in her beauticians, I would recommend Sharon would be best
to look at some sort of USB dongle. However I would recommend she downloaded all of her music
at home so as she didn't eat into her data allowance.
As for e–mail Sharon could create two separate e–mail accounts with windows hotmail as she could
personalise her e–mail addresses to her liking.
Conclusion
The laptop I am going to recommend is the ACER Aspire S3–391 Ultrabook.Overall it is the best
laptop for Sharon's business and personal needs.It provides her with the software she needs to create
her own advertisements, invoices, letters and to keep track of her accounts for her business. It also

provides her with the ability to surf the internet and go shopping online as well as download music
and due to the Acer having a DVD re–writer allow her to create her own CDs through windows
media player. The Acer also is the lightest laptop in this comparison and therefore will be easy for
Sharon to transport between her beauticians and home.

Types Of Attacks On A Computer System
Different Types of Attacks on
Computer Systems
What is attack on a Computer Systems?
Attack on a systems or network is defined on your network infrastructure. Attacker will first analyse
network environment and collect information in order to take advantage of the existing open ports
or vulnerabilities. It may include unauthorized access to company's resources.
Passive attack – In some cases, the purpose of attack is only to learn and get some information from
your computer system and your computer system resources are not manipulated or disabled in any
way, then it is called Passive attack.
And it is hard to detect that someone is monitoring you because you will not see any changes in
your system.
Active attack – Active attack occurs where the attacker accesses and either alters, disables or
destroys your information or data. Attack can be happened either from outside of the organization
means Outside Attack or someone from within the company who is an "insider" that already has
access to the network which is called Inside Attack.
Some of the attacks will be attacks targeting the end–users like Phishing or Social Engineering,
those are usually not directly called as network attacks.
Methods of attacks
These are the methods that can be used to make an attack on a computer system. Distributed attack
– A distributed attack are very strategic attacks. It requires particular code such as a Trojan horse or
back–door program, to a trusted software that so, with that

Technology And The Computer System
The brain has the capacity to recall information that was forgotten for a long space of time,
regardless of deleted information; the brain experiences some kind of traces that leave sequel
remaining in the neuron. It is the same thing that happens in the computer system after information
are deleted. For instance, after an address is programmed on the GPS to retrieve and lead to a
destination, the information is automatically encoded and released to track the direction leading to
the desired address. Just like the human brain, the computer has the capacity to capture and
memorize multiple information, and may proceed by a rapid retention after some information are
deleted. It seems like when an information is erased from the computer, it attempts to build or
download new program to prevent the definite dilution or process to save the deleted information
through new programs.
Retrospection to the GPS, it has the option to retain many destination once input to it systematic
artificial brain or memory; the memorization can be kept for a long time as long as the machine and
its mechanism would remain active in terms of operation. By determination, if you happen to delete
every single encoded information from the GPS, even though the system is renewed, you will
noticed that the machine is still remembering some of the previous deleted addresses. In reality, the
human brain is more proficient in encoding and decoding information and its memorization capacity
is more advance

Why was the Operating System Need
Surely by now you 've realized how important that role is the computer operating system.
Excogitate the Windows operating system on the same computer does not have any operating
system. The computer was called into the Micro Computers or Micros. Each time the machine is
used to separate different basic methods of their own. The program did not have any similarity with
any other program. If you were to create a computer game for any game developer to another
computer, but it was totally unemployed. Since it was separate from one computer to another
computer language, so it was absolutely impossible to establish the relationship between them. At
that time, CP/M operating system called the problem was eliminated. Micro Computers When the
CP/M started to use the same program, they are able to run on all computers. And a separate
computer program written by the developers in a separate CP/M began to write for the program.
Technology and computing innovation came.
But in the 1980s, when an organization called the IBM Personal Computer mesinera for his intense
popular CP/M can not claim they are unable to buy it. As a result, one of the great talents of the
young man, Bill Gates as an alternative began to write his own

Computer Operating Systems And The Computer System
The computer operating system is one of the biggest changes we are seeing in today's world. With
the rise of the cloud, digital software delivery and applications, the computer operating system is
playing catch up to these new trends. The center of the computer as always been the operating
system and the Graphical User Interface that comes with it. Computer operating systems have come
from a past of no User interface and being a command line base to the modern day Windows 8 and
Mac OS's of application based. If operating systems focus on Applications, cloud and digital
downloads for software, this approach will take the computer operating systems into the next twenty
years of computing. Computer Operating systems used to the center of a Vendors development. In
the modern era, mobile Operating systems have become the focal point with computer operating
systems taking the back seat. The computer operating system must match the experience and eco
system of the mobile devices. Focusing on the Graphical user interface will help create that
experience, from the application tile to the scrolling and how a user handles features will be key on
developing the computer operating system of the future. The problem with a classical approach to
computer operating systems is the fact that being mobile and being connected to data do not go
together. People are connecting to data from all point of the world and an operating systems needs a
way to help people connect to their data for

The Turing Test And The Theory Of Computer System
Can a machine think? Is a long lived question humans have had? If a machine can think then it
must have the same intelligence as a human, then right? If a machine has human intelligence, then
does that mean it has a mind of its own? It is desired by many humans to know if one day the
answers to all these questions could be yes. In hopes of figuring this out, a testing method was
created called the Turing Test. This test was created by an English mathematician named Alan
Turing in the 1940s and 1950s. Alan Turing was interested in the idea of artificial intelligence, or the
theory of computers being able perform tasks like humans. In result of introducing this theory,
Turing developed a testing method called the Turing Test. This would answer the question Can
computers think? The Turing Test consist of three subjects. Two of these subjects are humans and
the other is a computer system. One human is the questioner who is required to ask the other two
subjects a series of questions. By the responses of the other two subjects, the questioner has to
determine which subject is the computer, and which one is the human. In order to receive accurate
results, the test is repeated many times. If the computer system is believed to be the human subject
by the questioner, then the computer system is confirmed to have artificial intelligence. However,
questioning must be in a specific style for accurate test results. Computer systems have an
advantage over humans in certain

Internet Is A Global System Of Interconnected Computer...
Internet is a global system of interconnected computer systems. The internet, as we see today,
allows low–cost anonymous communication. The advance in technology has led to faster
communications. For example the change of dependency from postal service to much faster e–
mails, online banking, social networking etc. Everything is now at our fingertips. We can now sit at
the comfort of our homes and do certain tasks which were earlier time consuming. Today business
has easier global access due to Internet. It is cost–effective and almost all the functions can be
automated to make it easier and faster. Even communication has become cheaper and faster. But as
Dr.Leonard Kleinrock stated, these benefits are a perfect combination to do bad things ... Show
This stage is not yet reached, but the growing needs for more customer–friendly, easily accessible
and device–independent technology is pushing these developments.
He has also expressed his views on Nomadic Computing which means that the Internet would be
accessible for all devices anywhere and anytime. The Internet, at present, is accessible anywhere
and anytime, but we are still to work on all devices being able to plug–in on the Internet. Internet
was made with the assumption of a fixed desktop usage. Dr. Klienrock expresses his concern about
no availability of an IT administrator to look up the network issues personally when one is on–the–
go i.e travelling, which involves switching between networks at different areas. His solution for this
problem is a portable system support administrator for trouble–free internet service on any network
that one can connect to and is available round–the–clock at anyplace for any device.
His vision includes Smart Spaces. As explained by him, Smart Spaces is the concept of bringing
cyberspace out of one's machine out in to our physical world. He foresees the Internet being able to
automate everything to make life easier by making all appliances able to communicate to each other
and also to the customer. He says this embedded technology is possible by installing thousands of
processors per human which can communicate, has memory sensors, cameras, microphones,

The benefits of certifications can be looked at from the perspective of the job seeker and from the
employer looking to better the skill of themselves or for their staff. There is however the conflict of
employers and employees over whether or not the company should pay for the certification. Some
employers feel that paying for the certification will give the employee more ammunition to
negotiate raises and promotions with little benefit to the company. The employee and the employer
need to find the right fit for individuals wishing to obtain an IT Certification that will benefit both of
them justly. Keston, Geoff (2007). IT Certification Options, Faulkner Information Services. The pay
scale that you can expect to receive will depend on the degree that you obtain but can range

Computer System Upgrading
Issue:
Due to the rapid technological advances in computer systems as well as operating systems in the
business world, we must upgrade our computer systems throughout our company in order to gain an
edge on our competitors. We need to replace the central processing units in every division of our
company with newer units that are in line with the most sophisticated computer systems also being
used by every one of our competitors.
Background:
The computers currently in question have been in use for approximately 12 months as of November
2011. The computers we currently use are of lower quality and were most likely purchased at a
bargain price. The result of this approach has been a computing system that is quite unreliable.
Since the beginning of the summer of 2012, employees have reported a number of technological
setbacks including:
Malfunctioning audio cards
Inadequate Memory
Failed ventilation.
Malfunctioning power supplies.
Audio card malfunction continues to be an on–going problem with the current computer systems in
our company and in many situations our computers are rendered completely useless when the job
requires sound. Failed ventilation also continues to be a huge problem with many, if not all, of the
computers used throughout our company. When computer fans malfunction, it can cause the
computer to overheat and permanently damage it and all of the information in it, which raises a
drastic level of concern due to the fact that we store all of our

Designing A New Computer System
Case Study 1
Three friends have asked me to configure a new computer for each one of them. The first one is a
gamer, and she needs a competitive gaming system. Another wants to purchase a computer for her
home office where she has a small travel agency company, and the third would like a notebook or
laptop computer that he can use for schoolwork. Each one of my friends has a $2000.00 budget to
create the perfect computer system for each of their needs. First, we will create the perfect gaming
system for my friend in need. With the gaming system we will be starting from scratch. First things

not much difference between AMD's and Intel's in ... Show more content on Helpwriting.net ...
The two have been tested against one another, and honestly there is really not much different
between the two in game playing performances. However, the SSD has proven to be drastically
faster than the HD. I am going to go with the SSD with this gaming system because it loads faster,
transitioning maps throughout the game is significantly faster, and overall it means that your
computer will boot at a significantly faster. Overall one would have a better experience because it
makes the overall functionality of the computer better as a whole. The Samsung 840 EVO 240 GB
would be a great one to choose. It can be found for $129.99. It is a little on the pricey side, but it
will be well worth it. Next we need to configure a reliable computer system for my friend that has a
small, at home travel agency. With this system I would also recommend buying an already made
system, and perhaps doing a few upgrades. Dell has the OptiPlex 3020 Micro which is a descent
system for an at home business. It comes with an Intel Pentium G3240T Processor which is dual–
core with HD Graphics. This dual–core processor has plenty of horsepower to work with for a small
business, so there is really no need in upgrading this to a quad–core processor. It will allow you to
answer e–mails while running Word, Excel, and PowerPoint, along with the Web browser. It also
comes with 4 gigabytes of RAM, and there is

Hacking Is The Responsibility Of The Computer System
The argument between two hackers who say that it is the responsibility of the owners of the
computer system to provide adequate security to keep hackers at bay are completely wrong. Neither
their argument nor their perspective holds ground. Before we look into the reasons behind why they
are wrong, it is important to first comprehend in detail about hacking and hackers. So what is
hacking? The term hacking was first promoted by the famous MIT between 1950s and 1960s. It all
started as a fun experiment in a lab, but it led to something completely different today. Hacking is a
term used to describe unauthorized, illegal intrusion into a network of connected systems or just an
individual system. It is a technical effort or a process that is used to exploit the vulnerabilities of a
system or connected systems to gain unauthorized access. Today it is synonymous with malicious
activity on the web. The act of hacking is carried out by powerful and highly skilled programmers
known as hackers who possess advanced knowledge about the systems. They do it because they are
confident about their skills and succeeding in their hacking attempts. These proficient individuals
are extremely inquisitive who are in pursuit of private information that is not publicly available.
Accessing confidential or private information is just one small part of hacking. They are capable of
controlling, modifying and denying the system from any kind of connections or cripple the system
entirely bringing it

INTRODUCTION:
As the use of Computers have increased now–a–days with improvements in the technology which
brings both advantages and disadvantages. Advantages comes with technological developments and
disadvantages are like frauds happening using technology. These frauds using technology are called
Cyber–attacks where intruders or hackers break into others computers without permission and
access their personal data. Computer Ethics deals with values and principles in using the technology
in right way without any illegal activities. People who are not aware of ethics cause ... Show more
Computer Ethics mainly deals how computer professionals should act while working with
computers. Decisions need to be taken keeping in mind the values, disciplines of a person or an
organization. This needs to be defined in order to educate people against cyber–attacks. These ethics
should educate people to determine right or wrong while taking decisions. Ethics is an important
topic in each and every field like Computers, Education and also in bringing social awareness
among people. Like how we follow ethics in our regular life in making decisions between right or
wrong, we should follow the same when using technology. It is important to have ethics defined
because if we don't have ethics there will be many cyber frauds caused easily without thinking what
is right and what is wrong. Ethics mainly concentrates on decision making, values, responsibility of
one's own data and also others data (Wong, 1995) [3]. Computers store lot of information in their
memory like personal information, banking information, health information, here privacy is an
important issue of computer ethics.
Specific guidelines, policies, rules should be developed by organizations which should be
acceptable by majority of computer users in following computer ethics. People who follow morals
and values in everything they do automatically implement the same morals

Computer Based Information System:
Computer Based Information System (CBIS) is an information system in which the computer plays
a major role. Such a system consists of the following elements: * Hardware: The term hardware
refers to machinery. This category includes the computer itself, which is often referred to as the
central processing unit (CPU), and all of its support equipments. Among the support equipments are
input and output devices, storage devices and communications devices. * Software: The term
software refers to computer programs and the manuals (if any) that support them. ... Show more
Decision support systems assist managers who must make decisions that are not highly structured,
often called unstructured or semi–structured decisions. A decision is considered unstructured if there
are no clear procedures for making the decision and if not all the factors to be considered in the
decision can be readily identified in advance. Judgement of the manager plays a vital role in
decision making where the problem is not structured. The decision support system supports, but
does not replace, judgement of manager.
4. Office Automation Systems
Office automation systems are among the newest and most rapidly expanding computer based
information systems. They are being developed with the hopes and expectations that they will
increase the efficiency and productivity of office workers–typists, secretaries, administrative
assistants, staff professionals, managers and the like. Many organisations have taken the First step
toward automating their offices. Often this step involves the use of word processing equipment to
facilitate the typing, storing, revising and printing of textual materials. Another development is a
computer based communications system such as electronic mail which allows people to
communicate in an electronic mode through computer terminals. An office automation system can
be described as a multi–function, integrated computer based system that allows many office
activities to be performed in an electronic mode.

Computer Ethics and Information Security
a. Introduction
The consideration of computer ethics fundamentally emerged with the birth of computers. There
was concern right away that computers would be used inappropriately to the detriment of society
compromising information security, or that they would replace humans in many jobs, resulting in
widespread job loss.
Ethics– Guidelines or rules of conduct that govern our lives, work, behavior and communication in
both public and private undertaking.
Ethics are a set of moral principles that govern an individual or a group on what is acceptable
behaviour while using a computer. Computer ethics is a set of moral principles that govern the usage
of computers. One of the common issues of computer ... Show more content on Helpwriting.net ...
In that way, it is like a book: Obtaining illegal copies of copyrighted software is as bad as
photocopying a copyrighted book. There are laws against both. Information about the copyright
owner can be embedded by a process called watermarking into pictures in the digital format.
7) Thou shalt not use other people's computer resources without authorization: Multiuser systems
use user id's and passwords to enforce their memory and time allocations, and to safeguard
information. You should not try to bypass this authorization system. Hacking a system to break and
bypass the authorization is unethical.
8) Thou shalt not appropriate other people's intellectual output: For example, the programs you
write for the projects assigned in this course are your own intellectual output. Copying somebody
else's program without proper authorization is software piracy and is unethical. Intellectual property
is a form of ownership, and may be protected by copyright laws.
9) Thou shalt think about the social consequences of the program you write: You have to think about
computer issues in a more general social framework: Can the program you write be used in a way
that is harmful to society? For example, if you are working for an animation house, and are
producing animated films for children, you are responsible for their contents. Do the animations
include scenes that can be harmful to

Differences Of The Computer System
c) The output I received from dir /O was the same I received when I used the dir /L command.
One of the differences between the two commands is that one returned the subfolders in lowercase
(L) and the other in uppercase (O). The dir /O command returns the subdirectories inside my work
directory in sorted order, but in this case there wasn't much difference because Windows sorted out
this specific subfolder by default. As I looked deeper into the output, I found another difference
between one command and the other. When I used the L command, the return displayed the
document 57 untitled–1.py before the videos directory, as opposed to the O command that
displayed the .py file in the end of the list. The reason behind this is ... Show more content on

For example the command dir /s /w /p would list all the files and folders in the current directory
and the subfolders after that, one page at a time. Since my current directory is Chris the output to
this command displayed more information than I can share. I will share just a sample of the entire
output. d) dir (No file or subfolder was found during the execution of the command. I believe the
reason to this is that the OS blocks any access to that folder. If files or subfolders are modified the
OS could stop functioning.) After multiple tries I have realized that none of the nine commands
work. One of the reasons why is that absolute path and relative path are invalid commands.
There has to be another way to navigate through absolute and relative paths than with the commands
used in this exercise. Also, this exercise is misleading because the result of a command depends of
the location of the current directory and the directory to begin from is not specified in the
instructions. Also, I don't need a command to know what the absolute and relative paths are in any
case given. In number 1 for example, the entire address constitutes the absolute path:
C:WINDOWSWeb. In this case since I am working in the Web directory, the relative path
would be WindowsWeb. The absence of the slash makes a difference when determining whether
the path is absolute or relative. Below is a screenshot that justifies my way of thinking. 1– Functions

How Human Computer Interactions Incorporated Into Computer...
2. Purpose
The purpose of the authors is to introduce the capabilities of context–aware design and give an
insight into how it can positively affect and benefit the user's lifestyle. The authors inform the
audience of the three types of context–aware computer systems and uses prototype examples to
clearly explain them to an audience who would not be knowledgeable about this field. The article
highlights how human–computer interactions incorporated into computer systems are continuously
evolving to provide a more personal, efficient and user friendly experience. This has further
extended onto systems that recognise contexts and situations allowing less user inputs and more
about understanding and analysing the user's preferences.
3. Key Information
3.1 Framework
Context aware design is the concept of computer systems being attentive of the user's setting or
context. It will recognise engagement and interactions from the user and model the situations to
accomplish a set task or purpose. The fundamental framework of context aware designs takes into
consideration a user's personal needs which may be affected by many factors such as habits, self–
image, and issues of motivation. Thus, many questions are raised and answered in the planning
process regarding the purpose, intended audience, inputs and outputs required etc. to design such
technologies that are able to understand and interpret what the user's goals are. The prototype
examples exhibit endless possibilities and

A Study Of Computer System
Nowadays, computer is able to help in a wide range. Such as Economics, Physics, etc. Since 1987, a
study of computer system to support clinical decision making has been proposed by Edward H.
Shortliffe[5], with the rapid development of computer science, this approach is applied more and
more often and not only in clinical situation. As a tool, computer system could be used to collect
data, make statistics and calculation with no problem. According to Sprague study, Decision Support
System has been defined[6]， Decision Support system aims to gathering and store the knowledge–

Users share the relevant information each other make the search engine provide alternatives through
key word search. Still, this is also a similar function with Step 3.
C. Limitation of Traditional Decision Making Steps
Computer System has the ability to help Decision Making. However, Belton stated that Decision
Making Software could be able to support decision making, but software cannot replace decision
making since it does not have the driving force[7]. This is also the limitation of computer system
due to the nature of binary system. Software engineer is required to apply strict logic when they
programming.
Fuzzy Logic becomes popular in programming in order to help computer system to solve more
complexity problem for accurate result. Fuzzy Logic has been applied on Decision Making Software
already, but it has limitations such as decision maker can only gathering small amount of
information at one time[8].
Decision Making Software provides alternatives after users input the relevant information, but it
assumes that people already have the clear aim. However, people also face problems with single
goals and multiple goals[9], complicate think troubles users from the start of the traditional steps. In
the meantime, the factors consideration is limited due to the lack of background knowledge provide.
Therefore Traditional Decision Making Steps will provide an

Operating System And The Computer System Essay
Introduction: An operating system is a vital component of the computer system. The common and
simple devices like refrigerators and microwave ovens does not have an operating system. The
complex systems which handle several components, functions and processes usually have an
operating system. The operating system is like the brain of a human being, the brain is an essential
organ in the body of human being which sends signals and helps functioning of the human body.
Our intelligence, attitude, emotions and senses defines our presence, all these are possible because
of our brain. In similar manner, Operating System (OS) is the power behind a computer system. In
other words, operating system is brain of the computer and processor is the heart of the computer. A
computer is the concatenation of several hardware parts. The operating system manages computer
hardware resources and provides common services for computer programs and other application
software. Application programs or software usually require an operating system to function. For
basic hardware functions such as input and output and memory allocation, the operating system acts
as an intermediary between application software and the computer hardware, although the hardware
is directly accessed and executed by application code or software directly, the hardware will
frequently make a system call to an OS function or be interrupted by it. In simple terms, operating
systems track the activities of hardware and

A Model For Computer Systems Research
The author of this paper focusses on developping a model for computer systems research. He
presents data to show that the merit of the paper is dependent on variability between reviewers and
is zipf distributed. The author proves, with the help of game theory, that with noisy reviews and zipf
merrit, the authors have an incentive to sumit the papers too early and too often which makes the
conference reviewing and systems research as a whole less efficient. The popularity of peer to peer
systems are reflects its potential to provide scalable performance and high degree of robustness for a
variety of applications. This paper focusses on another peer to peer system, the systems research
community since there are many similarities between system research community and peer–peer
system. They lack central control. Progress occurs through the individual researchers interacting
through the conference publication system.
In this paper the author uses peer–peer systems to develop a model of computer systems research
conferences. The author believes that, the current practice of computer systems research is harmfull
in two ways. Conference program committees spend enormous amount of time on what ends up for
many papers being close to a random throw of dice. Worse conference reviewing encourages
misdirected effort, by research community that slows down research process. By illuminating the
above two issues the author hope to reduce their impact. He also provides some suggestion to

the central software component to any computer. The main brands of operating system are;
Windows Mac OS, Sun Solaris, UNIX, DOS and Linux. Each brand has its own take on what makes
up an operating system. Windows is the most commonly used operating system around the world.

Its current best–selling products are the Microsoft Windows operating system and the Microsoft
Office suite of productivity software.
Starting in 1980, Microsoft formed an important partnership with IBM that allowed them to bundle
Microsoft's operating system with computers that they sold, paying Microsoft a royalty for every
sale. In 1985, IBM requested that Microsoft write a new operating system for their computers called
OS/2; Microsoft wrote the operating system, but also continued to sell their own alternative, which
proved to be in direct competition with OS/2. Microsoft Windows eventually overshadowed OS/2 in
terms of sales. When Microsoft launched several versions of Microsoft Windows in the 1990s, they
had captured over 90% market share of the world's personal computers.

The Operating System Of A Computer
The Operating System of a computer. How does it work many say, what does it do other say. The
operating system or some people in the world also call it the OS, which mean the same. The OS is
the first program that gets installed and booted on to a new computer. The purpose of an operating
system is so that the end–user can interact with the computer and hardware, helping him/her use the
right software/apps needed depending on what operating system they are using. The OS helps you
multi task on you PC, so you can run multiple software at the same time. The function of a
operating system gives commands to the hardware and also tells how much resources to use from
the hardware to complete the needed tasks. The OS manages all the connected hardware in your PC
such as hard drives, a mouse, keyboard, displays a cursor on the screen which allows you to
navigate threw the system much easier. Now a days we see fancy and colorful screens with a bunch
of icons and windows that users use to help get around files and other programs assisting them to
complete their daily tasks. The operating systems of the 21st century are easy to navigate because
most operating systems now have a GUI which stands for Graphical User Interface, which allows
users to see icons, windows, folders, files systems and much more instead of just a command line
with black and white blinking text like back in the older days. For example, lets say you want to
transfer your pictures from your smartphone to you

hours and continuing the budget for the Intern's salary. Subsequently, there is definitely a market
and commitment for using analytics in the Registrar's Office. Describe your company's progress
within each stage of competing on analytics; How does your company create competitive advantage
with analytics? The current climate of the Office would correspond to Localized Analytics, the
second stage of the Competing on Analytics Stages Model (Davenport, 2007). The Office has
analytical capabilities and potential, as the Systems Developer and Associate Registrar have
analytical backgrounds that are not fully utilized. Their particular skillset could be used to improve
the processes within the Office as well as the way data is processed by College decision–makers.
Results Upon an analysis of the current capabilities and processes, the Registrar's Office is found to
be lacking in analytical characteristics. Using suggestions in the Davenport text, we can examine
certain processes and determine where analytics can be implemented. The way that this paper
explores options for competing on analytics differs from the text in the sense that the Office is not
profit–maximizing. How does your company compete internally on analytics? As of last semester,
the Office does not compete

Computer Viruses And Its Effects On A Computer System
A computer virus is a malware program that, when executed copies itself into other data files,
computer programs, or the boot sector of the hard drive with 95% of viruses doing no more than
that. (1)(2). A virus might attach itself to a program such as a word document program. Each time
the word document program runs, the virus runs too and it has the chance to reproduce by attaching
to other programs. (3) Nowadays, it is extremely important to be aware of viruses because they can
cause very dangerous consequences such as identity theft and fraud. When people generally think
about computer viruses, they normally think about an attack on a computer system, however, they
may not be aware of how common computer viruses are. It can be beneficial to know a few of the
different types of viruses, the kind of damage they can cause and methods to protect yourself from
them. In this essay, we will be covering when computer viruses first made an appearance and
contrasting this to how they are like now on social media. Also, we will be covering how they work
and what can be done to prevent the growing risks of computer viruses on social media. Computer
viruses were first widely seen in the late 1980s, with earlier viruses being pieces of code embedded
in a larger, legitimate program such as a spreadsheet program or a game. When the user downloads
and runs this program, the virus loads itself into memory then looks for any other programs on the
disk. If it can find one, it modifies the
