Database Architecture Comparison
Oracle 12c vs MySQL
MySQL was used as a comparison to Oracle 12c since my company currently uses MySQL in their database development. My role as a technical
writer at my company does not require me to fully understand our database work, but as I move more into a software engineer position, possibly at my
current company, I recognize the need to know and relate to the database my company uses.
Architecture of Oracle 12c:
Physical
Relational database management systems (RDBMS) have a number of characteristics that make them more efficient and preferred operational choices.
One characteristic is the independence of logical data structures as tables, indexes, and views from physical storage structures. Because the logical and
the physical structures are separate from each other, physical data storage can be managed and organized without affecting access to logical structures.
Renaming a database file, for example, does not rename the tables stored within that database file.
An Oracle database stores Oracle data in file sets within persistent disk storage. Persistent disks are storage devices that function similar to physical
disks in a server or desktop. They are used to ensure data redundancy and optimize performance, as they are located independently from the virtual
machine instances, which allows for detaching or moving persistent disks. This keeps data available even after instances are deleted.

Software Localization Strategies
2. LOCALIZATION STRATEGIES
There are two possible strategies for software localization as:
2.1. For designing a new localized software product
This strategy based on designing and developing a software product according to specific culture from scratch. Developer can put every resources
needed for localized software product in some type of resource repository. This repository may be Windows resource files, .NET assemble files, or a
database. This resource repository is easily editable, and also eliminates the need for source code recompiling.
2.2. For localizing an already existing software product
Here it is assumed that the source code (in the source language) for the software product to be localized is already available. This strategy reuses the
existing software product for the target locale. The localization tool explained in this paper is based on this strategy. Programmer has the code of
notepad software (available in English) and this code pass as input test case to the tool.
3. SERVICE ORIENTED ARCHITECTURE
Service oriented architecture is software architecture design pattern that provide application functionality as services, known as Service–orientation.
Similar to cloud computing in SOA services are shared and there exists a cloud of services. Hence SOA based on the concept of cloud computing.
Cloud computing used to describe a variety of different types of computing concepts that involve a large number of computers connected through a

Essay about Design of a Reconfigurable Hybrid Database System
Design of a Reconfigurable Hybrid Database System.
"Disc Resident database systems (DRDBS)" are conventional databases systems in which data is permanently stored on discs. In "Main Memory
Database Systems (MMDBS)", the databases are stored onto the main memory. As the memory locations can be accessed directly using addresses,
they allow very fast access to the data stored on them. They show better throughput in processing transactions and respond much more quickly than
DRDBS. Because of the fast data access, the performance of MMDBS tends to rely on the computing power of the machine being used. In
"Reconfigurable Hardware Database Systems (RHWDBS)" transaction processing speeds are boosted using reconfigurable computing platforms that ...

The Execution plan further has various sub–execution plans for targeting any of the three execution engines. These are forwarded to the "Scheduler",
which allocates when each of the operations are to start executing on their respective engines keeping interdependencies in view. The execution plans
wait for their turn in a queue in the scheduler, from where they are directed to the execution engines. The Storage Management component manages
access to data sources (data dictionary, records from tables, logs, index data and backup etc.). Common transcation processing tasks are performed by
the Transaction Management unit. When data is requierd during transactions, the Transaction Management unit sends requests to the Storage
Management component, which in–turn provides the data's location's address.
The research paper being summarized only explains the "Reconfigurable Hardware execution engine (RHW–EXE)" (Figure 3). The other two are
"Main Memory Execution Engine (MM–EXE)" and the "Disc Resident Execution Engine (DR–EXE)".
Data enters RHW–EXE through the Execution Controller component from the Scheduler. The scheduler forwards it a "data–flow" graph,using which
the execution controller can orchestrate its execution. All of this then is passed onto the "Re–/configuration Controller" as transformed sequential
instructions. This controller configures the hardware algorithms of the operators. The Controller can perform placement,

Memory Management Challenges And Alogrithm for Traditional Memory Mapping
Abstract:–
According to the need of real time systems many algorithm have been use to allocate memory efficiently Real time system may crash if they do not
get memory on priority or request memory loss can also be prevented by using memory allocation algorithm our goal is to focus on traditional memory
management algorithm according to their efficiency and their response time to recognize the problem and limitation and challenges that occurs
problem which may reduce the performance of real time system. This research paper will help you in determining the real time memory management
algorithm technique the latency rate and problem.
Introduction:–
Efficient Memory management is performed by modern operating system and still working for efficient memory allocation for application because
the main stuff is to provide required memory block for application with minimum memory loss as compared to the traditional memory allocation
which is known as "Memory Fragmentation" which keep the records of those block that are free and those that are allocated to tasks. For the purpose
memory allocation designs are being used for example: Static Memory Allocation, Dynamic Memory Allocation describe in Fig: 1
Fig:1 {Memory Allocation}
Real Time System support both techniques and both of them distributes memory in different way in
Static Memory Allocation, memory is allocated at compile time it has efficient

The Mac OS is the product of Apple, which was created in 1976 by the late Steve Jobs and Steve Wozniac. Mac OS, unlike Microsoft's Windows, is
an operating system designed only for the Macintosh computers. Whereas Microsoft's creation of Windows seemed more or less linear after the late
1980's, Apple circulated a number of different computers with different OS's, such as the Apple II, Apple III, the Lisa, in addition to the line of
Macintoshes. The ultimate brilliance behind Apple's development of its operating systems is vertical combination: Mac also develops both its own
hardware and software. However Microsoft takes a different approach: it provides the OS that is used by almost all IBM compatible computers
manufactured. Of all the individual personal computer ventures that Apple started however, only the top sellers of the Macintosh remain in production
and continue to evolve.
The first Mac was preceded by the Apple I, the Apple II which was very successful, the Apple III which was a disaster, and the Lisa which was a
disaster almost as bad as the Apple III. It was introduced in 1984, but development on Mac OS began in 1979. When presented, it was the first system
to rely exclusively on a graphical user interface to respond to user input. However it was the recognition of this graphical user interface that
encouraged Microsoft in its process of Windows.

Computer Networks And Its Impact On The Retail Store Front
With the use of mainframe computers, we have gained cost–effective critical transaction processing because of the mainframe's scalability; reliable
hardware and software compatibility; and, the mainframe's security infrastructure makes maintaining and managing the mainframe more feasible.
Compared to commodity servers, mainframe transaction processing is scalable because many businesses experience massive increases in
computational loads (Hallman, 2015). Let us consider this circumstance: During a retail store front's hours of operation, there may be many customers
making product purchases. Simultaneously, there may be many customers seeking refunds on their product purchases. One can also consider that this
retail store front offers its services over the Internet with the use of an e–commerce operation called metrics management. This e–commerce operation
encompasses web analytics, channel metrics, financial metrics, and product metrics. With the use of metrics management, one can measure the
effectiveness of the Internet channel and the retail store front channel by analyzing the quantity of product purchases and product refunds to deduce
which channel promotes a financially effective service; or, one could objectively consider to have these channels work in tandem to capture a product
purchase in any way possible. In this circumstance, the quantity of product purchases and product refunds are metrics that require computational loads
because the mainframe would store and

A Short Note On Scsi Test Vehicle ( Stv )
Introduction
SCSI Test Vehicle (STV) is a project to develop an FCP Storage emulator using FICON Express 16G channel adapter present on System z machine.
STV is a specialized Firmware (FW) load into a channel adapter that provides the function of a FCP Target (Fibre channel SCSI Storage Control Unit).
STV emulates IBM shark disk storage.
This document is intended at describing the design and implementation of STV Emulation support on Power Servers/Blades. The scope of this
document is mainly limited to STV component in STV Type FC channel firmware. This document contains information collected from other documents
and design discussions. STV Emulation support on Power Servers/Blades enables qualification/test floor teams to use the STV Type channel firmware
to test SCSI stream protocol capable devices not just on system z but other servers such as zBX and zFX as well. Problem Statement
The Current STV based storage emulator requires a FICON express I/O Hardware and system z for emulation. This is useful for testing in a System z
environment but proves uneconomical in regular zBX or zFX qualification. Moreover since STV uses the resources within the FICON express
module, which are limited. Emulation of Enhanced features such as multipath or increased LUNs is not possible. This limits the test coverage of the
test team. This project tries to work around some or most of the limitations by moving STV emulation to a Power server.
Limitation of STV:

Operating System:

An operating system is an interface between a user and the hardware of a computer. It is just a set of software that manages computer hardware and
controls the operations on the computer. Operating system is the base of the application programs because they cannot contact the hardware directly. It
does not do any work itself; it just provides an environment in which the other programs on a computer can run. Therefore, when a user enters or
sends a command the operating system makes sure that the command is executed or not, if not it displays a message explaining the error. Without
operating system a computer is of no use it is just a metal block.
Types of Operating System When considering about the types of operating systems, generally there are four types:
Real–time operating systems:
These kinds of operating system are used to control machines, scientific instruments and industrial systems. They have a very little user–interface
capability and no end–user utilities.

The segmentation scheme in Intel 80386 microprocessor is more advanced than that in Intel 8086 microprocessor. The 8086 segments start at a fixed
location and are always 64K in size, but with 80386, the starting location and the segment size can separately be specified by the user.
The segments may overlap, it allows two segments to share address space. To send the necessary information, segment tables with segment selector as
index are used. At any time, only two segment tables can be active. They are Global Descriptor Table (GDT) and a Local Descriptor Table (LDT).
This two segment table only can be executed by the operating system.
Segment table is an array of segment descriptors which specify the starting address and the size of the segment. Each segment descriptor has 2 bits
specifying its privilege level, called as the Descriptor Privilege Level (DPL). This DPL has to be compared with Requested Privilege Level (RPL) and
Current Privilege Level (CPL) before processor grants the access to a segment. If the DPL of the segment is less than or equals to the RPL as well as
the CPL, then the processor will grant access to a particular segment. This serves as protection mechanism for operating system.

Arrium management was locked in tense negotiations with the lenders syndicate led by the four banks to find an acceptable solution to the large debt

The decision to enter voluntary administration puts a question mark on the future of the loss–making Whyalla unit. While speaking to the reporters in
Adelaide on Thursday, Labour MP Kate Ellis, said that the state government will not be able to make a difference and save jobs on its own and it was
not correct to give the Arrium workers false hopes.
In the whole process, the only party which is most affected are the workers of the Whyalla–based steel unit for no fault of theirs. The management

Computer Systems Working Around Us
Today, as a society, we all seem to accept the trend of doing multiple things at the same time because of the limited amount of time we are given on
a daily basis. We find ourselves juggling many tasks at once; whether it is time with family, work, or even a favorite hobby, we all have to find time
to manage all of these things while maintaining some kind of balance. It can be very difficult today to find time to do all of these things and one way
to make it a lot easier is by using computers. While scientifically proven that it is impossible for our brains to do multiple tasks at the same time, we
still seem to try. But now that we have so many amazing mini computer systems working around us, we can now do the multi–tasking that our hearts
desire. Our computers can do many processes simultaneously, allowing us to do many things that we want at the same time. But how do these
computers handle all of these processes and applications at the same time? Well, in short, computer memory. To describe the way that memory works, I
will be explaining a few of the many components of computer memory and how it is managed. Memory management is the act of managing computer
memory. The topics that I will include in the paper will consist of the following: Dynamic memory allocation,Virtual memory, memory leaks and stale
references, fragmentation, large memory and cache systems.
The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to

This was because even though they had screwed up the initial test prototypes. They had sent a total of 10 faulty memory units out of the 100 and they

they were given another chance as they did not want to give the entire contract to a single company. They were given half the contract with a few
given clauses that there will be zero defective pieces and that they have to reduce their final cost. Acme took this second chance seriously and then got
their process running perfectly and after extensive cost cutting efforts they were able to reduce their cost by 20 percent and thereby secure the full

This room was very large, kept refrigerated and housed several mainframes. These machines were typically 8–9 feet tall, about 3 feet or more wide and
they were made of grey colored steel. They had lots of lights and dials and such. The data storage was reel–to–reel tape onto which data was
downloaded twice a day.
So how Big is Big?
The main purpose of a mainframe was to run commercial applications and large–scale computing, such as that done by the IRS, and banks where
enormous amounts of data are processed sometimes millions of records a day.
A typical mainframe has the following characteristics:
В·A mainframe has several CPUs.
В·Memory is hundreds of Gigabytes of RAM and It has tons of hard drive storage.
В·Its processing power is over 550 Mips.
В·It often has different cabinets for storage, input/ouput and RAM.
В·Distributes the workload over different processors and input/output devices. It can handle a large number of users.
В·All processes are running on the host and not on the terminal.
В·Output is sent to the terminal through a program running (in the background) on the mainframe. In my case it is called PIMS.
В·Nothing else goes over the line
Management processes, such as program management and task management, are separate. A mainframe is usually associated with centralized

scan the items that they procure from the store and skip the baggage section to get the items for free of cost. There is no mechanism to check whether
the items are scanned or not if the tag associated with is removed or tampered. This security exposure can lead to the disastrous effects where there is
no screening. Moreover I have a seen a few checkout systems in the local retailers where there is no one screening at the self–checkout system, In fact
it was quite easy for a person who wants to get the item for free. One can use false weights while scanning the bag just by placing only a little of
amount what he/she has got from the store and later fill up the bag with some more items of same kind. This is a major security exposure where the
system cannot check the scanned weight and the weight that is placed in the bag is equal or not. Hence the person who wants to falsify the weights can
easily cheat the system with this flaw in the security.

A WSN is a type of wireless networks that consists of collection sensor nodes which are tiny devices. Each sensor node of the network has different
processing capability. It may contain multiple types of memory (program, data and п¬‚ash memories), have a RF transceiver, have a power source
(e.g., batteries and solar cells), and accommodate various sensors and actuators. The nodes communicate wirelessly and often self–organize after being
deployed in an ad hoc fashion [13, 14]. Optimum need of each sensor node is to maximize its own utility function. Also the whole network requires

How Does Code Access The Same Page Frame Within A Page Table?
OS Assignment –7:Udaydeep Thota Student ID: 010025210
8.5 What is the effect of allowing two entries in a page table to point to the same page frame in memory? Explain how this effect could be used to
decrease the amount of time needed to copy a large amount of memory from one place to another. What effect would updating some byte on the one
page have on the other page?
Ans: If the two entries in a page table point to the same page frame in the memory, then the users can use the same code or sometimes data in the
future. For example if two users wish to use the same code, then instead of loading the code two times in to the table, one user can load it in to one
table initially and later the other user who would like to use that code access the same memory location. This will help both the users to fast access to
memory, less time consumed for context switching and hence overall effectivememory management is done. The main disadvantage in adopting to
this type of technique is that in case of one user updates the data in the table, then the changes would be reflected to other user who uses the same
memory as well. Hence there may be inconsistency between the users who wish to modify and those who would not like to modify it.

CREAMS : The Challenges Of ISA-Homogeneous Systems
The paper then takes a brief detour from talking about CReAMS to talk about attempts that have previously been made to solve many of the same
challenges that the authors hope to solve with CReAMS. The paper first talks about ISA–homogeneous systems, namely ReMAPP, Thread Warping,
and big–LITTLE, and then the heterogeneous system KAHRISMA. For all four of these systems, the benefits and drawbacks are provided, which is
meant to provide context for how the benefits of both homogeneous and heterogeneous systems were determined. The authors hoped to use what they
learned from these systems to create CReAMS. CReAMS is a homogeneous system that achieves simulated heterogeneity dynamically using a binary
translation mechanism. CReAMS also uses a ... Show more content on Helpwriting.net ...
The system would have a four set associative address cache with 64 entries, a private 32 KB four–way set associative data cache, and a private 8 KB
four–way set associative instruction cache. This section drew heavily on what we learned in class about pipelining, logical units, and memory caching.
This made for a great way to apply knowledge learned in class.
The paper then presents the final aspect of the system, which is specifically of the authors' design. This is what the authors call dynamic detection
hardware, or DDH. This hardware is responsible for detecting instructions, as well as allocation in the datapath described above. It is a four stage
pipelined circuit with the stages instruction decode, dependence verification, resource allocation, and update tables. The paper uses a simple loop in
code to demonstrate the four modes of the hardware. The four stages are probing, detecting, reconfiguring, and accelerating. This a very interesting way
of approaching allocation in the datapath and is quite different from anything we learned in class.
The paper finishes by presenting the experimental results of CReAMS against two different, more typical SparcV8–based systems and basically has a
victory lap after showing greater performance across a wide variety of applications along with greater energy efficiency, especially in more complex
applications.

1.Operating System:
An operating system is an interface between a user and the hardware of a computer. It is just a set of software that manages computer hardware and
controls the operations on the computer. Operating system is the base of the application programs because they cannot contact the hardware directly. It
does not do any work itself, it just provides an environment in which the other programs on a computer can run. Therefore, when a user enters or
sends a command the operating system makes sure that the command is executed or not, if not it displays a message explaining the error. Without
operating system a computer is of no use it is just a metal block.
Types of Operating System When considering about the types of operating systems, generally there are four types:

August Wilson Fences Analysis
"Fences" by August Wilson
August Wilson is ranked as one of the critical voices in American theatre. His plays are a revelation of remarkable talent that mentions on the African
American lifestyle and experience and simultaneously creates a global appeal. Fences, one of his plays is a reflection of his rhetorical aims of using
art in changing the existing relationship between the blacks and society as proof that the African American culture is fit for offering sustenance.
Fences by August Wilson gets its title from the main character, Troy. In the beginning, he builds a fence for his wife as he engages in a conversation
with Bono, his friend. The fence is completed by the end of Act 1 and Bono, and his wife had previously placed a bet that he would buy her a new
refrigerator if the fence would be successfully built. Set up in Pittsburgh, PA on an African
–American section between the late 1950s and 1960s, the
play rotates around father and son conflict. Troy is a garbage collector of African–American origin and was once a famous ballplayer within the Negro
Leagues before inclusion of the blacks in the American leagues. His son Cory has a talent for athletics sports and targets to win a college scholarship
from football.
Cory pleads with his father to allow him to quit his job at the grocery store to be fully involved in football. Nevertheless, his father does not accept
which bars Cory from joining the high school team. This shows that Troy is not sensitive to Cory's wish, but on the contrary, he has the will to fight
for his rights which sees him rise to become a garbage truck driver in the city. It is sad that he denies his son the opportunity of becoming a
sportsperson. To make matters worse, Troy cheats on his wife Rose but show compassion to his brother Gabriel who is mentally disturbed. Gabriel got
a head wound when he took part in the World War II, and his friendship with Bono is firm.
Troy has a mistress, Alberta who unfortunately passes on while giving birth and the mistreated Rose takes in the child. However, Rose refuses ever to
obey Troy again. The commitment of Gabriela to asylum leaves Troy and Cory entirely apart after Cory mentions that Gabriel's government considers
the services that were being

This paper is based on CUDA, a parallel computing platform model, which utilizes the resources of the Graphical Processing Unit (GPU),
increasing the computing performance of our system, hence creating a robust parallel computing unit. In this paper, we will be introducing a brief
history on CUDA, it's execution flow and it's architecture to handle processor intensive tasks. We will also be highlighting some of it's real life
applications and the difference in performance as compared of the only CPU based architectures. Also, since most of the CUDA applications are

So, in 2007, NVIDIA released CUDA, which provided the parallel architecture, to support the usage of the GPUs. It was designed to work with
programming languages such as C/C++ or Fortran and this really helped specialists in parallel programming to use CUDA, rather than to learn other
advanced skills in GPU programming[10] . The model for GPU computing is to use a CPU and GPU together in a heterogeneous co–processing
computing model[3]. The framework is designed such that the sequential part of the application runs on the CPU and the computationally–intensive
part is accelerated by the GPU. From the user's point of view, the application is faster because it is using the better performance of the GPU to
improve its own performance. пїј Figure1: Core comparison between CPU and GPU пїј3. Architecture Since GPUs have large number of resources
with hundreds of cores and thousands of threads to be utilized and have very high number of arithmetic and logical units. Hence it provides a huge
parallel architectural framework to work with. пїј Here is a block diagram that generally describes CUDAs architecture. Figure 2: Block diagram for

Essay on Cis Memory Management
CIS:328
Abstract
The purpose of this paper is to show how memory is used in executing programs and its critical support for applications. C++ is a general purpose
programming language that runs programs using memory management. Two operating system environments are commonly used in compiling,
building and executing C++ applications. These are the windows and UNIX / Linux (or some UNIX / Linux derivative) operating system. In this
paper we will explore the implementation of memory management, processes and threads.

Other functions need to be used to segment the virtual memory pages into useful segments. Since virtual memory is allocated by pages, a number of
special paging features can be used on virtual memory that cannot be used on other types of memory. For instance, pages can be locked (to prevent
read/write access), or they can be protected from any particular access mode (read, write, execute).
Heap memory and allocating a memory block
Each program is provided with a default process heap, but a process may optionally allocate any number of additional heaps, if more storage is
needed. The heap functions will manage their virtual memory usage automatically, and therefore heaps can be set to grow if they are being filled up
with data. If a heap is allowed to grow automatically, the heap functions will automatically allocate additional pages as needed. On the x86 architecture
the heap grows in size towards higher memory addresses.
To use heap memory, a heap must first be allocated (or a handle must be obtained to the default heap). Once you have obtained a handle to a heap, you
can pass that handle to the memory allocation functions, to allocate memory from that particular heap.
Managing process specific memory

The cpu executes a large number of programs while its main concern is the excution of uer programs, the cpu is also needed for other system
activities. These activities arecalled processs. A process is a program in execution. Typically a batch job is a process.

Advantages Of Dynamic Allocation
Introduction: –
A dynamic storage allocator accomplishes space for things whose lifetimes are not identified by the system at the period of their establishment.
Dynamic storage provision has a substantial influence on computer presentation.
A dynamic storage allocator on a multiprocessor should have the capability to gratify numerous requirements simultaneously.
Dynamic Allocation: –
Two methods of dynamic allocation
Stack allocation
Constrained, but modest and well–organized
Heap allocation
Further general, but fewer proficient
More challenging to implement

Worst circumstance can have minor block of memory between each 2 procedures
Flexible number of partitions, variable size.
Conclusion: –
All methods necessitate that the complete program must:
a)Be encumbered into memory
b)Be deposited closely
c)Remain in memory until the work is finalized
Each procedure puts simple limitations on the size of the works: can only be as huge as the prevalent partitions in

Indian Voting System Using Electronic Voting Machine
Indian Voting System using Electronic Voting Machine (EVM)
Introduction: Traditionally a voting machine has been defined by mechanism of the system to cast votes and categorized by the location where the
system calculates and show the votes. With advances in technology EVM came into existence. This system in which citizens interact to cash their
ballets that is common parlance to electronic ballet marking system, when the voter makes his or her choices, provides to verify their casted votes the
mechanism used in this is DRE (Direct Recording Electronic System). Primarily the EVM'S are manufactured by BEL (Bharath Electronics Limited)
and ECIL (Electronics Corporation of India Limited). It ensures flawless voting and thus has become more widespread. Retains all characteristic of
voting while making it more beneficial.
History of EVM: In India all the earlier elections is done by putting the stamp against candidate name and folding the ballot paper and dropping into a
box. This is time consuming process and very much prone to errors until EVM came into existence, EVM's are manufactured in 1989–90 and are first
used in experimental basis in 16 assembly constituencies in 1998. In 1980 Mr. MB Haneefa designed the first voting machine. In 2014 elections,
Election Commission of India introduced NOTA (None of the above) option in EVM's.This is the latest improvements in EVM.
Working of EVM: EVM consists of two units, they are ballot unit and control unit Fig :

A page replacement strategy is used to determine which page to swap when the main memory is full. There are several page replacement strategies
discussed in this book, these methods are known as Random, First–In–First–Out, Least–Recently–Used, Least–Frequently–Used and
Not–Used–Recently. The Random strategy randomly selects a page in main memory for replacement, this is fast but can cause overhead if it selects a
frequently used page. FIFO removes the page that has been in the memory the longest. LRU removes the page that has been least recently accessed,
this is more efficient than FIFO but causes more system overhead. LFU replaces pages based on

The Rules of Records Management
Why is records management important? Many people who are not pretty familiar with records might think too seriously about records management.
However, people who are in business or the people who have their own business have to know about records management procedures enforced by
governments around the world. For example, in the book "Intensive Records Management" by >>>>>, we can learned about the rules of records
management and the legal procedures that apply to it. Records management is important because of its ten most important reasons: to control the
creation and increase of files or records, to reduce working costs, to improve the competence and productivity, to assimilate new records management

Another important filing method is Subject Filing. For subject filing we have to take in consideration six rules. Inspecting, indexing, coding,
cross–referencing, sorting, and filing and retrieval. Finally, I am going to talk about Geographic filing. Geographic filing also has six filing methods.
Inspecting, indexing, coding, cross–referencing, sorting, and filing and retrieval.
For example, (Century 21 Autos Augusta, ME*) when filing Maine is the key unit, Augusta is second unit, Century is the third unit, 21 is the fourth
unit, autos is the fifth unit or last unit. Therefore, when you file, it becomes (Maine Augusta Century 21 Autos). This is how the rules for filing
methods work.
Then, I am going to discuss the use of computer technology in Records management, reasons to restrict access to documents to authorize users only,
explain the need for vital records protection and disaster recovery planning, and discuss the reasons to appraise records periodically in relation to their
period of usefulness.
Another great factor of the life cycle in records management is the reducing of operating costs. Recordkeeping requires the administrative part of the
financial affairs of a business for filing equipment, space in offices, and staffing to maintain an organized filing system or to search for lost records
when there is no organized system. For example, it costs about $20 less per linear foot of records to store inactive records in

Operating Systems And Software Systems
An operating system is a system software that manages and control all interaction between a computer hardware and software. There are several types
of operating systems, for example, multi–user, multitasking, single user and more. The first ever created OS date back in the 50's. As computer and
technology progress over time operating system kept evolving. Among the commonly used operating systems of today is Linux, a Unix–like type of
OS. Linux creation begins in 1991 as a software kernel and part of a small project developed by Linus Torvalds, a student from a University in
Finland. Under GNU (general public license), the software was available as a free and open source and gave everyone the right to access, change and
modify its original design. Because of the way it is designed it can run on multiple platforms such has Intel, Alpha and more. Like many open systems,
Compared to more expensive operating systems, Linux was an economical alternative for cost–conscious companies that needed to quickly create
Web–based applications. When more developers are able to provide input about a system, it becomes easier to fix flaws and bugs that hinder
performance; roll out improvements; increase the speed of system evolution; and combine an application 's components in new and exciting ways not
intended by the original developer. (Ecommerce) Linux has three major components the kernel, the system library and the system utility. Some of the
great features of Linux include

Computer Technology And Its Advancement
Computer Technology and its Advancement in Nursing
As nursing students, we are taught to utilize the nursing process in almost every aspect of our work. The nursing process communicates and
coordinates care with all other clinical disciplines. It assists in coordinating discharge planning, education, teaching, and transition of care. Utilizing
informatics and healthcare technologies is one of the nursing essentials of the Master's in Education Program. Nursing is the hub of information flow
in all types of healthcare organizations. Developing the science and technology of nursing informatics will enhance the information available to nurses
in clinical practice management, education, and research. The American Nurses Association or ANA defines nursing informatics as, "a specialty that
integrates nursing science, computer science, and information science to manage and communicate data, information, and knowledge in nursing
practice". Nursing informatics first got its start in the late 1960's when the 1st computer systems were implemented in hospitals. Nursing informatics is
based on information technology. Information technology is any technology which processes and communicates data. It includes computers, voice,
data and image sensing, communication devices, graphic devices, multimedia imaging, etc. Information technology also entails the use of things as
simple as a pen and paper, telephones, and fax machines.
Computer technology/nursing informatics is designed to assist

4. Diligence: Unlike human beings a computer is free from tiredness and lack of concentration. It can continuously work for hours without creating any
error and without grumbling. And a computer will also all the processes with same speed and same accuracy.
5. Versatility: Versatility is one of the most wonderful things about the computer. One moment it is preparing the results of an examination the next
moment its working with picture. Briefly a computer can perform almost any task if the task can be analyzed as binary logical instance.
6. Power of remembering: As a human being acquires new knowledge the brain subconsciously selects what it feels to be important and worth
retaining in its memory. This is not the case with a computer. A computer can store any data and information as long as the user wants and can recall
them anytime to reprocess because of its memory compatibility. Even after several years user can use the saved data as he saved means it remains
unchanged.

Next, there are four basic functions of the operating system. Memory management takes part in main memory which is Random Acess Memory
(RAM). It retains the space of the main memory and checks whether it is valid and legal for the memory space request. The memory manager also can
track the usage of memory by sections.
Besides, processor management is also essential managers of the operating system. Basically, it tracks the processor status that takes part of allocating
Central Processor Unit (CPU). The main responsibilities of processor manager managed by Job Scheduler and Processor Scheduler. The Job Scheduler
