Vendor Managed Inventory System
In order to fully and efficiently utilize our proposed vendor managed inventory system, we have
performed extensive research of numerous hardware and software configurations. Among the many
obvious requirements of the system are cost, scalability, compatibility, and ease of use. Some
methods for consideration are outlined below.
• Cost – In order to keep costs down, we have decided to utilize the Internet. Vendors would be
responsible for providing their own computer system in order to access the VMI. Our role would
include maintaining a dedicated server, supplying software, and providing access.
• Scalability – In an effort to apply forward–thinking, we are recommending a system that will
provide all of the functionality and ... Show more content on Helpwriting.net ...
This process will involve these steps:
1. Unpacking the equipment .25 hours
2. Verification of shipped materials against packing slip .25 hours
3. Racking the equipment. .50 hours
4. Configuring equipment setup. 2 hours Total 4 hours
Software
For the VMI project it is recommended that the vendor be able to log into our system through a
Virtual Private Network (VPN). VPN will give the vendor secure access through our firewall. Once
they have logged into our network a java applet will be pushed to their desktop. When this applet is
run it will install Oracle 's JInitiator on the vendor 's machine to allow them access to our Oracle
Application database. JInitiator is an Oracle plug–in which Java applets, including the forms applet;
is executed from. The vendor will use this applet to access custom forms, reports and charts
detailing current inventory levels and consumption history on our Oracle system. Figure 1 The
vendor will assigned a vendor

The Common Internet File System
8. Data Storage Techniques
8.1 CIFS
The Common Internet File system (CIFS) is a native file sharing protocol used by computer users
across corporate intranets and Internet. It defines series of commands to pass the information
between the networked computers. CIFS implements the client/server programming model. A client
program sends a request to server program for access to a file or to pass a message to a program that
runs in the server computer, the server then takes the requested action and gives a response.
CIFS Functions are:
● Get access to files that are local to the server and read and write to them
● Share files with other clients using special locks
● Restore connections automatically in case of network failure.
● Unicode file names
Similar to SMB protocol, CIFS implements the Internet 's TCP/IP protocol. CIFS can be considered
as supplement of existing Internet application protocols such as the File Transfer Protocol (FTP) and
the Hypertext Transfer Protocol (HTTP).
Common Internet File System runs as an application–layer network protocol used for providing
shared access to files, printers, serial ports, and miscellaneous communications between nodes on a
network. It also facilitates an authenticated inter–process communication mechanism.
8.2 Network File System (NFS)
Sun Microsystems in 1984 developed a distributed file system protocol called Network File System
(NFS) allowing a user on a client computer to access files over a network much like local

Software And Flip Flop Gates
Abstract In recent years, much research has been devoted to the construction of extreme
programming; contrarily, few have evaluated the confusing unification of extreme programming and
courseware. After years of typical research into extreme programming, we demonstrate the
investigation of XML, which embodies the robust principles of complexity theory. WAG, our new
heuristic for courseware, is the solution to all of these challenges. Table of Contents 1 Introduction
End–users agree that relational theory are an interesting new topic in the field of cryptography, and
researchers concur. The notion that steganographers collude with empathic information is largely
outdated. Unfortunately, a robust problem in operating systems is the synthesis of online algorithms.
To what extent can wide–area networks be explored to address this problem? Our focus in our
research is not on whether architecture and flip–flop gates can interfere to fulfill this aim, but rather
on constructing new distributed methodologies (WAG). existing self–learning and cooperative
algorithms use hierarchical databases to locate adaptive theory. Even though such a hypothesis is
continuously an intuitive mission, it is derived from known results. Two properties make this
solution perfect: our method is built on the development of DNS, and also we allow spreadsheets to
study multimodal theory without the emulation of symmetric encryption. This combination of
properties has not yet been explored in existing

One can also easily see that no other component follows this growth rate.

the technology of magnetic disk specifically we see that disk density has been improving by about
50% per year, almost quadrupling in three years. Access time has only improved by one–third in 10
years.
Super fast processors and huge memories have to be 'fed' and a system is only as fast as it's slowest

ThreadMark). Each have their strength and weaknesses, and it often works well to run both types.
Real–world benchmarks may be as simple as timing how long it takes to copy a file, or they may
involve executing complex scripts that perform functions in many different applications. The main
advantage of these benchmarks is they measure performance using real applications. this same
advantage can also be a limitation, since the performance of one component may be artificially
limited by another. For example, we may be interested in disk performance, but a slow video
accelerator will slow down a benchmark that has a high proportion of video content. This in turn
could affect the workload presented to the disk drives.
Why Benchmark results may not be what we expect
Mechanical Latencies
The single largest contributor to low performance is the disk drive mechanical overhead. The
mechanical overhead consists of drive head seeks and rotational latencies. Rotational latency is the
time it takes for a sector on the disk media to rotate to the point under the read/write head. It is
inversely proportional to the rotational speed of the disk : the faster the disk spins, the shorter the
rotational latency.
Software and Firmware Overheads
Software overhead is the time it takes for commands to be passed through the operating system and
software drivers. Firmware overhead relates to the time it takes for the host adapter and disk drive to
process

Design And Implementation Of A Businesses

businesses' network can play a major role in the success of that business. This proposal will outline a
technical solution to provide Worldwide Advertising Inc. (WAI) with a flexible and reliable IT
infrastructure to meet their needs for the next 2 to 3 years. As both sites in Los Angeles and New
York are already connected through an IPSec VPN tunnel our recommended proposal will include a
solution for WAI's core IT services, application services, active directory services, and file and print
sharing.

2012 Standard Edition. Plus, all servers ... Show more content on Helpwriting.net ...
While, the initial implementation will use the full GUI installation of Windows Server 2012, the
overall summary of the planned enterprise with an IT team is incorporated in the table below: Site
Server 2012 Core Server 2012 Full GUI Standard
Los Angeles Active Directory, Domain Controller, DHCP, and DNS File & Printer Server, SQL,
Exchange, and IIS Web Services New York Active Directory, Domain Controller, DHCP, and DNS
File & Printer Server
Each site will be configured in an identical manner to aid with the ease of deployment,
configuration, and administration. Utilizing the Windows Server 2012 Core installation will be ideal
for the infrastructure servers running the Domain Controller, Active Directory, DHCP & DNS
services. Additional servers will be configured with Windows Server 2012 Standard Edition Full
GUI installation to provide greater flexibility for current and further application utilization. They
will also be able to provide File & Printer services, as well as Web services through the use of
Windows IIS. Windows 7 Professional should be the operating system deployed across all
workstations. On top of the 90 workstations already being allocated, additional workstations should
be purchased for unforeseen issues and new hires. In order to ensure that each workstation is the
same and can be deployed quickly, a WAI image should be created and maintained using Windows
System Image Manager.

Hyper-V And Virtual Computer Expression From 2008 To 2008
From the transition from 2008 to 2012 there were many changes in respect to Hyper–V. There are
distinct services which were not available in 2008 which now make it much more robust than the
previous years. In 2012 Hyper–V allows for shared virtual hard disk. In doing this it is now possible
to share virtual HD files (.vhdx) between multiple virtual machines. This in turn makes it possible to
deploy a guest failover cluster which is no longer bound to storage topology. The shared virtual HD
is an ideal use for SQL Server database files, file server services running within a Virtual Machine,
or Database files which reside on shared disks. The quality of service within Hyper–V was also
increased with 2012. Unlike previously, Hyper–V ... Show more content on Helpwriting.net ...
These resources include display config, audio, printers, clipboard, smart cards, drivers, USB
devices, and supported plug and play devices. One final addition is the implementation of automatic
virtual machine activation. It is now possible to implement installs of VM on a computer where
Windows Server 2012 R2 is properly activated without having to manage product keys for each
individual VM. This is even in disconnected environments. The VM can be activated in remote
locations and with or without an internet connection. It is possible to track VM usage and licenses
from the virtualization server without requiring any access right to the virtual machines. There are
some major differences between 2008 and 2012 versions of Hyper–V regarding support of memory,
storage, network, and its overall manageability. In Windows Server 2008 physical memory was
limited to 1TB. There were only 512 virtual processors per host and 4 per virtual machine. Memory
per VM was limited to 64GB. There could only be 384 active Virtual Machines with cluster nodes of
16. Looking at the progression to 2012, the physical memory caps at 4TB. There are now 2,048
virtual processors per host and 64 per virtual machine. Memory per VM is now up to 1TB. There
can now be 1, 024 active Virtual Machines with cluster nodes of 64. Server 2012 now allows for live
storage migration within Hyper–V only being limited by what hardware will allow. The virtual disk

Macintosh was introduced in US $1.5 million Ridley Scott commercial. 1984, It was mostly aired
during the third quarter of the Super Bowl XVIII. Which is now known as a "watershed event" and a
"masterpiece" by many many americas. Many believed the Macintosh ad was more successful than
the Macintosh itself. The Macintosh definitely saved humanity was IBM's attempt to dominate the
computer industry. After the Super Bowl commercial, The Macintosh went on sale, and came with
two applications made to to show off its interface. MacWrite and MacPaint. These applications were
first demonstrated by Steve Jobs, Know for his famous Mac Keynote speeches. Some people labeled

Cloud computing is a fairly new technology; it is separated into three separate categories. The first is
Infrastructure as a Service (IaaS) this service is mainly used by companies to cut the cost of buying
computer hardware such as servers , they also save on maintenance cost since the virtual servers is
maintained by the company that rents them [1]. The second category is Software as a Service (SaaS)
this service deals with providing software which is usually rented, this allows users to have multiple

EC2[4]. These perpetrators covered their trail using bogus names to create the Amazon account,
while they had the facility to hack into Amazon's servers; they were directly aiming for the
PlayStation Network [4]. According to nist.gov there is no way of knowing where the exact location
of a user/criminal the closest an investigator might be able to get to them is the datacenter [5]. The
possible steps investigators might have taken for this crime begins with PSN's website source files
where they realized the cloud provider may have played a major role in this crime [6]. The
prosecutor would then legally request for all of its data from Amazon's EC2 servers, where a search
warrant will be issued to them [6]. They would then compare data from PSN and EC2 where they
will investigate all the links found [6]. This is possibly where investigators would have found the
perpetrator's fake account [4]. The investigators hit a brick wall with this investigation because of
the main problem with cloud computing which is the ability to pin point a location of the
perpetrator. Some of the tools used in Cloud forensics in this particular case will

he became a father. He cared a lot about his children and their education. Some examples of him
caring for his children is he attended their parent/teacher meetings, did not allow them to watch TV
or use devices and had them eat healthy. Steve Jobs often talked about how he would try to balance
his life of being a father, and his work. This is a quote Steve Jobs said in a interview about his life,

Administering Desktop Clients: IT Consultation for Mr. Green

Usually this service would run from a server as opposed to a workstation running Windows 7
Ultimate. The closest Mr. Green could get to GPOs would be putting restrictions on the workgroup
functionality, but there are very few settings that would mimic the functionality of a server.
Several years pass, and Mr. Green is now running a network with Windows Server 2008, as well as
Windows 7 Enterprise. The migration of the other machines on the network is now simpler, as there
are machines on the network that are designed to simplify network infrastructure. One technique he
could use to manage his other workstations and install Windows 7 Enterprise correctly on each one
is a function called AppLocker, which "Specifies what software is allowed to run on the users PCs
through centrally managed but flexible Group Policies" ("Windows 7 enterprise," 2013). He also has
the option to put the installation media on his Windows Server 2008, within a folder that is shared
across all computers. This is different from Windows 7 Ultimate because he can set group policies
and permissions on each group of programs and files his workers need access to. Group Policies are
yet another way that Mr. Green can implement software installations across a few dozen computers,
and is probably the most effective way.

Advantages And Disadvantages Of Hard Disk Interface
The hard disk interface characterizes the physical segments and logical segments based on the
connectivity of the hardware to the computer. In the 1980s, the most mainstream disk interfaces
were ST506/412 and ESDI, which are presently out of date. These old drives utilize two strip links
(a 20–stick data link and a 34–stick control link) versus the single–lace link utilized by present day
drives. Discovering one of these old double link drives in a computer voluntarily builds up that

SCSI interfaces are accessible in different subtypes, which have distinctive physical and electrical
interfaces and transfer rates. Present day SCSI hard disks are the biggest, quickest disks accessible,
although as of late IDE and SATA hard disks have started to approach SCSI in size and speed. Inside
the distinctive SCSI flavors, interfaces are very much characterized and institutionalized; yet
arranging SCSI to chip away at a standard PC can be complicated.
SCSI disks are occasionally utilized as a part of desktop PCs since they cost more than ATA disks
with comparable limit and execution. For instance, if an ATA hard disk costs $90, a comparable
SCSI model may cost $175. Further, the higher cost of SCSI drives, utilizing a SCSI drive requires
introducing a SCSI have connector, which may add $50 to $300 to framework cost.
In any case, spending additional cost on SCSI may enhance general performance more than
spending a similar total on a fast

Hard Disk
Hard Disk The Physical Characteristics of All Disks The hard disk has one or more metal platters
coated top and bottom with a magnetic material similar to the coating on a VCR magnetic tape. In
the VCR the tape moves by a fixed recording and sensing device (the "head"). In a disk, the
recording head is on a movable metal support called the "arm". Information is recorded onto bands
of the disk surface that form concentric circles. The circle closest to the outside is much bigger than
the circle closest to the center. Since each metal platter has a top and bottom surface, there are at
least two magnetic circles for each size and location. However, a disk may have as many as five
platters, producing ten of these identical circles at the ... Show more content on Helpwriting.net ...
Some disk models are optimized for this and reduce cost, power use, and heat by limiting seeks
performance. This is definitely not the type of disk on which you want to install an operating
system. If the disk moves the arm as fast as it can to the right location, once it gets there it may have
to wait for a long latency period while the data rotates around to the arm location. Newer smarter
disks can calculate that this is going to occur and respond by using less power to move the arm more
slowly into position while still getting there with time to spare. This type of "intelligent seek" saves
power and reduces noise without effecting performance. One company took its Enterprise 15,000
RPM disk hardware and reprogrammed it to run at 10,000 RPM. Then they looked to see what
improvements they could get in exchange for the slower speed. Among other things, the amount of
data on the disk jumped from 300 to 400G while power use and heat dropped. The conclusion is that
while all disks work about the same way, in any given generation of hardware there are
opportunities to tweak, optimize, and specialize. Be careful when you purchase a disk intending to
get a general purpose system that you aren't buying one of the disks optimized for

Through the SAN, multiple paths are created to all data, so that failure of a server never results in a
loss of access to critical information. Enterprise data storage has the story of transitions from one
medium to another as the IT industry searched for ways to hold data and deliver access to it fast
enough to keep processors busy. Here, the following are the statistics of earlier storage devices.

Flash Memory 1990s Present
Storage is required by a computer because its memory loses all its data when it 's switched off;
DRAM is volatile. When a computer is first switched on its memory is empty and both code, which
tells the computer what to do, and data, the information that is processed, needs loading into
memory from a persistent – non–volatile – store.
Direct attached storage (DAS), storage area network (SAN), and network attached storage (NAS)
are the three basic types of storage. DAS is the basic building block in a storage system, and it can
be employed directly or indirectly when used inside SAN and NAS systems. NAS is the highest
layer of storage and can be built on top of a SAN or DAS storage system. SAN is somewhere
between a DAS and a NAS. Direct Attached Storage (DAS) the most basic storage subsystem that
provides block–level storage and it 's the building block for SAN and NAS. The performance of a

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:
High cost of testing for

SCSI (Internet Small Computer System Interface)! ! iSCSI is a transport layer protocol. How SCSI
packets are transported over a TCP/IP network is decided by this protocol. This protocol can be used
to send data over various area networks like

transmits block–level data between a iSCSI server and a iSCSI client located in a storage device.
The iSCSI protocol provides encapsulation to SCSI commands and rearranged packet to the TCP/IP
layer. These encapsulated packets are then sent over the internet on a P2P connection.
When these packets arrive at the destination, the protocol strips down the extra headers in such a
way that the SCSI commands are seen by the operating system as a local SCSI device that can be
formatted as usual. ! ! iSCSI is popular in small and medium businesses because of the way server

Data in the RAM only resides there during the duration the program is running or the program
instructions are being performed, when the computer is turned off, the RAM loses all it's data.
RAM is similar in behavior to a person's short–term memory while Hard Disk is comparable to a
person's long–term memory. Short–term memory focuses on the task at hand , but it can only store
enough information at a time, hence when it fills–up it will try to take information from the long–
term memory bank. Computers also work in the same manner, If RAM fills up, the processor
continually fetch and overlay existing data in RAM with new. Unlike Hard Disks, the RAM never
runs out of memory.
II. Expansion Cards
1. Controller a controller may be an expansion card, an external device or a chip which manages the
operation or functions of a specific task or command. They work as a link or a channel which
integrates two parts of a computer.(A good example would be Graphics controller which manages
access to Graphics card or Video Card )
Common Type of Controller Boards are:
a)Graphics Controller/Video Display Controller
b)SCSI host bus adapter
c)NIC or Network Interface Controller
d)Parallel port controller
Examples of Controller chips are:

Unit 1 Explain And Define The Following Components
Explain and define the following components
Hard drive – A hard drive is a non–volatile memory device used to store data permanently and
retrieve the same. A hard drive can store different types of data including text, graphics, audio,
video, etc. A hard drive works by using platters on which data is written with the help of a magnetic
head. The platters and head are encased in an air–sealed case. Hard disks used inside computers are
called internal hard disks and are located in a drive bay; they use ATA, SATA, or SCSI cables to
connect to the motherboard. They derive power from the PSU (Power Supply Unit).
RAM – Random Access Memory (RAM) is accessed randomly (without accessing preceding
memory bytes) by computers. Since data is read randomly, RAM is much faster to read from and
write to than other memory devices. RAM is volatile and can contain data only till the computer is
powered on, it loses data once the computer is powered off. RAM is called the primary memory and
is used to load parts of the operating system and drivers during device boot up. The most common
types of RAM include Dynamic RAM (DRAM) and Static RAM (SRAM).
ROM – Read–Only Memory (ROM) is a computer memory which contains pre–loaded data. This

This process of mapping a disk is called formatting or initialising. When you purchase a new disk,
they should be formatted for either PC or Mac. It may be helpful to reformat disks from time to time
as this deletes all the data on disk. During the formatting you process you can also determine
whether the disk has any faulty spots and you can copy important system files onto the disk. Hard
disks must also be formatted so that the computer can locate data on them. When you buy a
computer, the hard disk has already been formatted correctly and probably contains some programs
and data. You can format your hard disk if necessary but the process is different to that for a
diskette. Modern diskettes store data on both sides of the disk (numbered side 0 and side 1) and each
side has its own read/write head. When formatting a disk, the disk creates a set of magnetic
concentric circles called tracks, on each side of the disk. The number of tracks required depends on
the type of disk. Most high –density diskettes have 80 tracks on each side. A hard disk may have
several hundred tracks on each side of each platter. Each track is a separate circle. These are
numbered from the outermost circle to the innermost, starting with zero. Each track on a disk is also
split into smaller parts. Imagine slicing a disk as you would a pie. Each slice cuts across all the
tracks resulting in short segments or sectors. A sector can contain up to 512 bytes. All the sectors are

San Implementation Essay
SAN implementation over Gigabit Ethernet
A Storage Area Network is virtualized storage.
A storage area network (SAN) is a dedicated, centrally managed, secure information infrastructure,
which enables any–to–any interconnection of servers and storage systems.
A SAN can be configured to provide a nearly infinite pool of storage that you can grow and move
between servers as they need it. The storage can be added to and removed without requiring the
server to be rebooted. The services provided by the server continue to operate without interruption.
The primary purpose for implementing a SAN is to provide a large storage pool that multiple hosts
could access. Common storage configurations involve direct attachment of storage to a host. ...

What is Gigabit Ethernet.
Gigabit Ethernet supports 1000 Mbps over Ethernet media. Because it is similar to existing Ethernet
and Fast Ethernet standards in that it uses the same frame format and collision detection
mechanisms, Gigabit Ethernet is easy to integrate with existing Ethernet networks. It was designed
as a Ethernet backbone switch–to–switch and switch–to–server technology.
To provide the speed increase from 100 Mbps Fast Ethernet up to 1 Gbps, several changes needed to
be made to the physical interface of Gigabit Ethernet versus Fast Ethernet. It was decided that
Gigabit Ethernet will look identical to FibreChannel at the physical layer. By taking advantage of
the existing high–speed physical interface technology of FibreChannel while maintaining the IEEE
802.3 Ethernet frame format, backward compatibility for installed media, and use of full or half–
duplex carrier sense multiple access collision detect (CSMA/CD), customers will be able to use their
existing knowledge base to manage and maintain gigabit networks. They would not have to throw
away their existing network infrastructure.
Gigabit Ethernet is intended for Fast Ethernet backbones and switch to server links where existing
Ethernet networks are being aggregated onto the faster Gigabit Ethernet speeds. A company

The protection from viruses and worms is an incredible advantage Linux system has over Windows.
Linux possesses much greater processing power than Windows. Linux Servers holds a 39.6 percent
market share, while Windows makes up the second largest percentage of server operating systems
with 32.2 percent market share. In comparing the cost and market–share each system has its edge in
different situation. No one single type of operating system can offer universal answers to all your
computing needs.
Availability of Application software
Both Windows and Linux come in many flavors. All the flavors of Windows come from Microsoft,
the various distributions of Linux come from different companies (Linspire, Red Hat, SuSE,
Ubuntu, Mandriva, Knoppix, Slackware, Lycoris). Windows has two main lines: Win9x, which
consists of Windows 95, 98, 98SE, and NT class, which consists of Windows NT, 2000 and XP.
(Burgess, 2001) Windows actually started, in the old days, with version 3.x which pre–dated
Windows 95 by a few years. All the Linux distributions released around the same time frame will
use the same kernel. (Burgess, 2001) They differ in the add on software provided, GUI, install
process, price, documentation and technical support. Both Linux and Windows come in desktop and
server editions. Linux is customizable in a way that Windows is not. There are many special purpose

The Osi And Tcp Model
1. Introduction In this report, the OSI and TCP/IP models will be compared after going through a
brief history and how the models were made. The report will bring the reader a greater
understanding about the OSI and TCP model. The model shows the different layers for example for
the OSI model it has the following layers: Application layer, Presentation layer, Session layer,
Transport layer, Network layer, Data–Link layer and Physical layer. The similarities in the TCP
model would be: the Application layer and the Transport layer. This is then compared for the
differences to see which models layer has, that is different to the other. 2. The OSI Model 2.1. Brief
History In the late 1970's, two projects started separately, with the same ambitions: to characterize a
unifying standard for the architecture of networking systems. An individual was administered by the
International Organization for Standardization (ISO), and the other was undertaken by the
International Telegraph and Telephone Consultative Committee known as CCITT. In 1983, these
two documents were merged to form a criterion called The Basic Reference Model for Open
Systems Interconnection. This was too long to pronounce, so the standard is usually referred to as
the Open Systems Interconnection Reference Model, or more commonly known as the OSI Model.
The OSI model had two major parts: an abstract model of networking, called the "Basic Reference
Model" or the "seven–layer model", and a set of precise

Output hardware is components of or devices linked to a computer, which allow the computer to
transfer information to another computer system or the user of a computer system (Kroenke – pg74).
This output hardware sends information in the form of images, sound, or various other tangible
imagery usually, to some form of input hardware on another system. It is not designed to receive
data only to send. The most familiar of these devices is the visual display or computer monitor.
These monitors are usually synonymous with a computer and every system is equipped with or able
to connect to a Visual Display Unit. Projectors, audio systems, printers, and faxes are all examples
of output hardware. Microsoft Corporation in their endeavors to enhance everyone's life with the aid
of computing software has developed output hardware for the blind or visually challenged. Windows
also offers a function such as video narrator, that provides audio descriptions of videos
(http://Windows.Microsoft.com). In addition to these components windows is compatible with
numerous other programs and hardware components that are designed to enhance the lives of those
who are blind or visually impaired. More recently Microsoft has also included Braille output devises
and other hardware components in their product lines. For a quick reference for "Operating Systems

Carlson Shared Services (CSS) uses a centralized data processing model to meet business
operational requirements. The central computing environment includes an IBM mainframe, over 50
networked servers from Hewlett–Packard and Sun Microsystems. In this centralized data processing
unit all the servers and the mainframe had their separate disc storage. This dispersed data storage
scheme had the advantage of responsiveness; that is, the access time from the server to its data was
minimal. However, the data management cost was very high. There had to be backup procedures for
the storage on each server, as well as management controls to reconcile data distributed throughout
the system. RapidInsight framework enable organizations to integrate real–time, streaming data, to
gain real–time actionable insights, integrate and harmonize data from social media sites, public
datasets, and industry reports with data from enterprise systems (Fulton, 2015). The RapidInsight
framework gives analyst the ability to analyze data in real–time to respond quickly situations in
which businesses tend to encounter. A thorough look at the entire business operation, which

be a challenging task. Off premise planning becomes more complicated as the components that
make up the storage network are generally in the control of the cloud provider. It becomes critical to
maintain the integrity and security of the data, while still offering a seamless storage solution to the
business. The business user does not care where the data is located, or where an application is
hosted. It must be available as needed, with little to no noticeable performance degradation. High
Availability DFS Namespace A distributed file system (DFS) is a good way to offer high
availability, especially when DFS replication is taken into ... Show more content on Helpwriting.net

It is bad enough when the local, business network becomes unavailable, but if the Internet link goes
offline, it may take longer to resolve as the provider's network engineers are generally responsible
for getting it back online. It is often difficult to create hybrid systems that integrate with on premise
and off premise systems, and storage. There may be business reasons why there is a need for a
hybrid solution, and the cost and complexity of integrating storage and server systems may not be
advantageous to the organization despite the benefits. Data integrity and security is an additional
risk, and one that should not be taken lightly. The fact is, the cloud service has company data. While
it is true that there are likely contracts and security measures in place to provide assurance that the
data integrity and security will remained unchanged, high profile providers are excellent candidates
for threat actors. Despite this, there are benefits as well. The high–profile companies likely invest far
more in security measures than most companies would be willing to do. This offloads the security
requirements to the provider, while allowing the organization to benefit from the high availability,
cost reduction, and increased efficiency of cloud services (Weintraub & Cohen, 2016). Virtual
Infrastructure High Availability Virtual infrastructure is here to stay in the modern information
technology world. More services and critical applications will depend on the virtual

(Iomega's Jaz 2GB Gives Users More Storage Space and Solid Performance by Sheldon Leeman,
July 1998.) With capacities of 1GB and 2GB, respectively, these are well suited for storing digital–
video and image files, multimedia presentations, or DTP layouts. Mag–Optical (MO) and DVD–
RAM drives have tremendous capacities, but due to the high costs and relative obscurity of the
formats, few people have bought into these storage systems so far, being that their more adaptive to
Network Storage.
Media Cost
After the initial outlay for the drive, you'll be faced with the cost of the storage media the drive uses.
Keep in mind that what seems like a bargain may be a moneypit in disguise. For example floppy
disks are still the cheapest per–unit media at approximately 50 cents each, but on a per–megabyte
cost basis (around 35 cents per megabyte), they're the most costly form of storage. Also on the

expensive end of the spectrum are 640 MB, Mag–Optical disks, at about 5.5cents per megabyte, and
1GB Jaz media at 6 to 7 cents per megabyte. Jaz2 and super–floppy media end up costing between
3.5 and 5 cents per megabyte. The best deal in town is CD–R media, which cost under a penny per
megabyte.

Acronyms, Idioms and Slang: the Evolution of the English...
Acronyms, Idioms and Slang: the Evolution of the English Language.
Although the English language is only 1500 years old, it has evolved at an incredible rate: so much
so, that, at first glance, the average person in
America today would find most Shakespearean literature confusing without the aid of an Old–
English dictionary or Cliff's Notes. Yet Shakespear lived just 300 years ago! Some are seeing this is
a sign of the decline of the English language, that people are becoming less and less literate. As R.
Walker writes in his essay "Why English Needs Protecting," "the moral and economic decline of
Great Britain in the post–war era has been mirrored by a decline in the English language and
literature." I, however, disagree. It seems to ... Show more content on Helpwriting.net ...
In addition, Americans have, over time, given new names for certain things: what we call a trunk (of
a car), the
English call a boot; what we call an apartment, the English call a flat, etc.
But because they have been in use for so long, they are no longer considered to be slang words. R.
Walker writes, "if slang and jargon are fixed in the language, a process begun by their addition to the
dictionary, it helps to make them official." It seems then, that a word is slang only if it has not yet
been accepted, that it is instead a candidate whose initiation into the English language is determined
by popular opinion and time. Slang in America today, while varying from region to region, has one
major theme in common — it is short. And while history has shown that most of it will die — never
making official "word" status — to be replaced by new slang words, some of it will stay. The word
dis (short for disrespect), for example, has become a popular word used by more than just
Generation X. What's interesting, however, is that even the nature of current everyday prose has
begun to shorten: it is more direct and to the point. As an example of older–
–style writing, Stephen Jay Gould, in his essay "Counters and Cable Cars," writes: Consequently, in
San Francisco this morning, I awoke before sunrise in order to get my breakfast of Sears's famous
eighteen pancakes (marvel not, they're very small) before

Recognition of Gay and Lesbian Marriage and Pluralism Essay
Recognition of gay and lesbian marriage and pluralism
Word Count: 2024
What does pluralism reveal about the recognition of gay and lesbian marriage? What are the
strengths and limitations of this theory in understanding the recognition of gay and lesbian
marriage?
Power overlaps between interest and political groups and as a result, political decision–making is
reached through negotiation and compromise (Manley 1983). Indeed, when examining the
progressive debate concerning the legal recognition of same–sex relationships in Australia, the
perception that power is bartered through interest groups becomes highly plausible through the lens
of classical pluralist theory. There are competing visions of diversity in Australia, and behind ...

The classical pluralist model is distinguished by its example of power being relatively dispersed and
that decision–making is open to a variety of interest groups. In Australia, scholarship has settled
upon what Monsma and Soper describe as 'pragmatic pluralism' (1997) based upon political
expediency, explained by the practical character of Australian culture and in the context of same–sex
marriage, an interest in giving a 'fair–go' (Sky News Australia 2015). The most important
predictions about same–sex marriage and politics amount to the flow–on political participation and
organization of interests. This is a topic Australian people are interested in. This tenet of Dahl's
organizational pluralism urges individuals to query the conditions of rights, ritual and state
recognition in Australia (Dahl 1978). In this way, classical pluralism's strength in relation to the
marriage equality topic is that it speaks to a future where diverse relationships are supported, instead
of denied and shamed.
Australian classical pluralist theory is a conventional corpus, and its core ideas offer one of the more
relevant power analyses regarding polarized concerns for morality in the same–sex marriage debate.
Political theorist, Galston, argues that there is a strong case for pluralism being the most adequate
account of the moral universe mankind inhabits (1999). If this is the case, then the pendulum
