The Impact of Enterprise Storage Strategies
Introduction
When a business started, the related data has been generated. Along with the development of the
business, the data becomes larger and accumulates day by day. The accumulated data can be
transferred to meaningful information for the managers' decision makings. Storing and protecting
the data is essential to the development of the enterprise business. Today, almost all enterprises use
computer storage to store their data instead of the hard copy papers. In the past, hard copy papers
stored the data for the enterprise, but it existed too many potential risks, such as data loss, data
stolen, data destroy, or cannot sharing with others. In 1990s, more companies started to use
computer hard drive to store their business data; this change impacted the later development of the
storage strategies. Along with the technology development and the data becomes bigger and bigger,
big data problems appear. How can enterprise store such large data and manage such large data
effectively? Currently there are several classic storage strategies to help enterprise solve their data
storage problems, such as spinning media, flash, and cloud. The enterprise also can select onsite or
offsite option as their considerations based on their business environment. Security issues are
popular discussion topics as well in this paper.

Desktop Hardware And The Computer
Desktop Hardware Would you know how to fix your computer if it crashed and started to
malfunction? What if some parts were not working? Knowing desktop hardware if you own a
computer is important. Say if one part of your computer is malfunctioning and you knew which part,
you could easily replace that part if it is able to be replaced. The parts of the computer could save
you money and time for yourself instead of purchasing a brand new computer.
Floppy disks store a small amount of information, less than a CD or DVD. One important detail
about them is that they are portable, meaning they are able to remove. Floppy disks are easily
damaged while they are also inexpensive and tend to have a more tendency to lag. Some computers
still include a floppy disk but they are not as popular as they once were around the mid– 1970's.
(IBM) The sizes are varied from as small as two inches to around 8 inches in size. Floppy disks
were first developed in the early 1960's but were not available to the public until the 1970's. Early
computers did not have a CD–ROM drives and floppy disks were the only current way to install a
new problem. They have lost their popularity today because of the new technology that is improving
in our world. Floppies are usually used today to give an emergency boosts in old computers that
may tend to lag. Apple has created their own floppy disk with their personal computer, Apple Lisa
naming the floppy drive "Twiggy." Central processing unit (CPU) or

A Brief Note On The Twisted Pair Cables
2.3.3 Twisted Pair
There are two types of Twisted Pair Cables, Shielded Twisted Pair (STP), and Unshielded Twisted
Pair (UTP). Shielded Twisted Pair Cables have a very thin wire mesh that shield and protect the
transmission. STP cables are used for the older phone networks, as well as data and network
communications which are clearer and have less interference with the outside. Whereas Unshielded
Twisted Pair Cables have no wire mesh and are therefore not protecting the transmission in the
wiring. UTPs are mainly used for Local Area Networks (LAN) as well as telephone connections,
however these are more vulnerable than STPs (Shielded Twisted Pair).
3. Backing Storage
3.1 Types 3.1.1 Disks
You can back up your storage on a separate Hard Disk and on other forms of Disks such as a Floppy
Disk. Using another Hard Disk to back–up your storage is useful because it means that you can
back–up everything that is stored on the Hard Disk you want to back–up. However it all depends on
the size of Hard Disk you get. If it's much smaller than your current Disk, then you will only be able
to back–up the more important stuff that is stored on the Disk. Whereas if you got a Hard Disk that
is bigger than your current Disk, then you will have room to back–up the whole Disk, as well as add
extras when you need to back–up more recent data.

Pen drives can be used to back up data by putting them into the USB port of the device you wish to

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

Cnc and Dnc
Difference between CNC & NC machines
NC machines
In a Numerical Control machine, the program is fed to the machine through magnetic tapes or other
such media. The original NC machines were essentially basic machine tools which were modified to
have motors for movement along the axes.
CNC machines
In a Computer Numerical Controlled machine, the machines are interfaced with computers. This
makes them more versatile in the sense that, suppose a change in dimension of a part is required. In
a NC machine, you would have had to change the program in the tape and then feed it to the
machine again. But in a CNC machine, you just change a variable in the computer and your
modification is done!!

Analog Monitor.
1). Digital Monitor: A digital monitor accepts digital signals rather than analog signals all monitors
use CRT technology, which is essentially analog. The term digital, therefore, refers only to the type
of input received from the video adapter. A digital monitor then translates the digital signals analog
that controls the actual display.
2). Analog Monitor: This is the traditional type of color display screen that has been used for years
in televisions. All monitors based on CRT technology are analog. Some monitors are called digitals
monitors because they accept digital signals from the video adapter.
ii). Printer : Printer is a device that prints text or picture on a paper and in many cases on
transparencies and other media. There are many different types of printers.
Daisy wheel printer: There is a type of printer that produces letter quality type. A daisy wheel printer
works on the same principle as a ball head typewriter. The daisy wheel is a disk made of plastic or
metal on which characters stand out in relief along the outer edge.
b). Dot Matrix Printer: Dot–Matrix printers create characters by striking pins against an ink ribbon.

Each pin makes a dot and combinations of dots from characters and pictures. Dot–matrix printers
vary in two important characteristics.
Speed: given in characters per second the speed can vary from about 50 to over 500.
Print Quality: determined by the number of pins it can vary from 9 to 24. The best dot–matrix

The files first need to exist somewhere where the computer can reach them, our hard drive.
Currently, there are two different types of hard drives available on the market. Hard disk drives,
otherwise known as HDD's and solid state drives, otherwise known as SSD's respectively. Hard disk
drives have been used since the early days of modern computing. They act the same way as old
VCR and tape cassettes, with magnets. HDD's are composed of one or more circular, metallic
platters that currently spin at speeds of 5400, 5900, or 7200 RPM's14. Once they spin up to their
designated speed, a little arm with a magnet spans over the metallic disks and proceeds to read and
write to the disk, with reading being a whole lot faster than writing as the arm doesn't have to
change the arrangement of the magnetic particles on the disk. Solid state drives however are
different in respect to that they have no moving parts. They are little PCB's15 with silicon NVMe

Concerns Regarding Public Cloud Services
Many concerns pertaining mostly to public cloud services restrain the movement of the organisation
towards this new business model and gaining benefits aforementioned. Moving to cloud computing
services means renting off–premise IT resources that are managed by the cloud provider. This raises
several questions and concerns such as: what are cloud providers ' procedures to extit{protect data }
from destructive forces (e.g. fire, flood, earthquake) and to extit{secure it} from unwanted actions
of unauthorised users? , Is there any guarantee on extit{cloud services availability} on–line without
power cut? , and what about if cloud provider decide to extit{ discontinue cloud service?}.
Furthermore, the risk of extit{vendor lock–in} where customer unable to shift business data and
application interaction into another cloud provider 's services without substantial switching costs.
More specifically, each cloud provider requires a particular Application Programming Interface
(API) that imposes on cloud customers to develop their applications in a certain way to interact with
their cloud services. Thus, moving to another provider thrusts customer to re–develop its
applications based on the new cloud provider 's API requirement. Finally, data storage is growing
very fast due to the increasing reliance on information especially for business. This growth of data
storage requires increasing of IT budget to maximise IT resources including: storage entities,

Modern computers that are not laptops or Tablets have a mouse. A mouse is a round device that is
designed to fit into the users hand comfortably. The mouse's most important function is to control a
pointer on the screen. With this you can control what happens on your computer. The mouse on a
PC has 2 buttons, the left button is used to pick an object or a piece of text, the right button is to
access a menu on whatever the pointer is on. MAC's have only one button which controls
everything the mouse does. Nowadays PC mice have a round segment between the 2 buttons. This is
used to scroll down a piece of text easier. MAC's are more advanced and use a ball on the top of the
mouse. This is used for scrolling in any direction. This is useful for any documents in landscape
form. Older mice also have a ball at the bottom of it which judges the pointer's movement. The ball
is connected to 2 wheels that detect movement and moves the pointer; however these balls were
very sensitive and had to be cleaned every so often. They also needed something called a mouse mat

Inside The Pc : Cpu
Inside the PC CPU What is it and what does it do? Basically the CPU; or Central Processing Unit, is
the brain of the computer, retrieves and sends different information to the other components of the
build. The physical parts of the CPU are a 2inch Ceramic Square with silicon chip in the middle that
will lock into the specific location on the motherboard. Other than sending and retrieving data, it
also deals with the systems mathematical equations which (almost completely) is the same, because
the language that goes from each of the components is Binary which is a combination of 1 's and 0 's
the mathematics is when it changes the binary codes into an action. There are many alterations of
the CPU having different models, different cores and different speeds. Within the CPU there is a
clock that sends out electronic pulses which controls the speed of which the actions are done, this is
measured in Gigahertz (GHz) the user can change the speed, this is called over–clocking, this will
increase the number of pulses of information is sent out. You will hear the term "cores" when
talking about CPU 's which is different sections of the CPU sending out different information from
each core, the number of cores can differ from 1 to 8 and of course the more number of cores there
are, the faster the processor. Variations – companies, sockets and speeds Memory What is the

Customizing a personal computer requires a user to be familiar with the most basic input devices
and their functioning. In addition to getting known with input devices, it is also equally important to
inspect the actual usage of one's computer to determine what input devices would be applicable in
the context of its use.
(I) Keyboards
The keyboard is the most well–known input device and is used to introduce character and
commands into the system. The connectors on the keyboard have advanced over time from basic
serial connectors to PS2 connectors and the most widely available today are the USB connector and
cordless keyboards. The characters in a keyboard form an XY matrix arrangement of switch
elements which are entered to the system and are identified using a keyboard encoder [2].
The variations in the type of keyboard permit the user to make choices based on preferences. Some
of the latest variations such as the cordless devices had improved the mobility and are more user–
friendly. The user has a great opportunity to explore these variations in the market to find perfect fit
component at a low cost.
(II) Mice
Mice is an important input device, it allows the user to input information graphically by moving a
cursor or other screen images. The mice had become most essential component after the arrival of
the graphical user interface (GUI). The most common variations in mice available in the market
today includes an optical mouse,

What Is Hard Disk Drive?
Hard Drive Physical elements
What is hard disk drive?
A hard disk drive (often shortened as disc, hard drive, or HDD) is a nonvolatile storage device that
stores digitally encoded information on fast rotating rigid (i.e. hard) platters with magnetic surfaces.
to be precise, "drive" refers to the motorized mechanical side that 's distinct from its medium, like a
tape drive and its tape, or a diskette drive and its diskette. Early HDDs had removable media; but, a
HDD nowadays is usually a sealed unit (except for a filtered vent hole to equalize air pressure) with
fixed media.
How hard drive works?
A hard disk is a sealed unit containing variety of platters in a stack. hard disks could also be
mounted either in a horizontal or a vertical position. during this description, the drive is mounted
horizontally.
Electromagnetic read/write heads are positioned on top of and below every platter. because the
platters spin, the drive heads move in toward the middle surface and out toward the boundary. in this
approach, the drive heads might reach the complete surface of every platter.
Hard drive physical component
PLATTERS:
Platter is a circular, metal disk that 's mounted within a hard disk drive. many platters are mounted
on a fixed spindle motor to make new information storage surfaces in a smaller space. The platter
incorporates a core created from aluminum or glass substrate, coated with a filmsy layer of ferric
oxide or cobalt alloy. On each side of the substrate material, the

Storage Space Essay
Where is a very large, integrated collection of data in a Server, held? Yes, the Storage Spaces. These
Storage Spaces lets us combine individual hard disks into storage pools and these can then be
managed as a single entity. Storage Spaces is a technology that groups the storage pools and the
storage disks which will enable the virtual storage capabilities in Windows and Windows Server
(Microsoft Corporation, n.d). The available capacity in the storage pools are then used to create
virtual disks which are called storage spaces. Firstly in this paper, I would like to provide an
overview of the new Storage Spaces functionality and the Storage Space types in Windows Server

The first one is the simple storage layout that has no resilience, meaning it does not have the
capability of quickly recovering from the difficulties or the disk failures. This storage layout simply
writes the given data into multiple physical disks but doesn't make a clone copy or any information
about the parity. This type of layout is a good choice if your requirement doesn't need a backup of
data or the disk failure scenarios doesn't affect your requirements. This simple storage layout is a
good choice in terms of offering performance for your application if it has its own security
essentials. Another type of storage layout is the parity layout which not only writes the data into
stripes across the physical disks but also writes the parity information into extra copies. This layout
is suitable for the requirements that require maximum capacity with lower writing performances.
Example of using the parity layout is while archiving the media and when media streaming requires
huge loads. The last storage layout is the mirror layout which is similar to the parity storage layout,
but with greater performances when SSDs are added to the storage pool and when the storage tiers
are being used. This resilient type writes the data onto multiple physical disks along with making
extra copies of the data and offers protection to the data in the events of disk failures. The other
metric that describes the functionality of storage spaces are

Memory And Memory Of Computers
Memory
Have you ever wanted to know how certain files, documents and so on are being saved and what led
this to occur? The memory of computers is quite fascinating and there is so much that goes into
saving something on a computer. There are different types of memory that is found on computers
that is needed to make things work and that would be acceptable to the user. The main two that is
quite known in the computer world would be Primary and Secondary memory. There are 2 types
that make up the Primary memory and that would be Random Access Memory (RAM) and Read
only memory (ROM). The secondary memory consists of a hard disk drive, flash drive and zip
drive. There are also optical discs that are included.
One thing that is special in terms of computers would be the Primary memory. Primary memory is
divided into 2 types. The first type would be random access memory. RAM is in charge of keeping
data in a stored area so that it can be reached by the processor when necessary. RAM does a really
good job at laying away data in such a random basis. An article from the PC World have shown that
in this generation RAM has increased tremendously; it is said that " A review of systems that the PC
World test center has grown from a little over 90 MB to about 2 GB, spiking whenever Microsoft
releases a new version of Windows" (Stafford pg. 84). RAM has 2 forms, they are Static RAM and

Internal system unit components
What is a Processor?
This is the main part of any pc, because its run all of your computer resources including applications
and the operating system. The processor also communicates with all of your other components in
your computer and tells them what to do. The processor carries out millions of instruction every
second. The faster processor you have, the faster system you will gets. Such as, Intel Core i7, Intel
atom and inter core i5. – A processor, or "microprocessor," is a small chip that resides in computers
and other electronic devices. Its basic job is to receive input and provide the appropriate output.
While this may seem like a simple task, modern processors can handle trillions of calculations per
second.
What is the purpose of a processor?
The most important component of a computer is the central processing unit, or CPU, also called the
processor. The processor acts as the computer 's brain, running programs and sending and receiving
signals to attached devices to keep the computer running. Whether you use your computer or mobile
device to send email, take pictures, post online or browse the Internet, your processor handles all the
data and runs all the programs that enable you to accomplish these tasks.
What is the function of a processor?
The CPU has two main components, the arithmetic/logic unit and the control unit. The control unit
directs other portions of the computer system to carry out or execute program

This results in the cash portion of the purchase price available for payment to Seagate 's
stockholders in connection with the merger to be approximately $1.285 billion (less the amount of
rolled equity)".
"While many of the implied equity values for Seagate 's operating businesses summarized in the
table above exceeded the $2 billion purchase price in the leveraged buyout, Morgan Stanley arrived
at its opinion that the consideration to be received by holders of Seagate common stock in
connection with the merger was fair, from a financial point of view, to those holders, by considering
all of its analyses of the merger and the leveraged buyout, taken as a whole."
The passages show that Morgan Stanley fear value was $2 billion for the business operation. This
value is 43% lower than our valuation of $3.48 billion for the deal. The passages and the published
document are not clear why the fear value should be so low. This vague suggestion is more eccentric
when we look the valuation made by Morgan Stanley. It had made a valuation using different
methods such as comparable analysis, discount equity analysis, discount cash flow analysis, and
sum–of–the–parts analysis, and different scenarios (Figure XXX). Based on the values that Morgan
Stanley calculated, we calculated a weighted average value for it. Using the same weighted for each

by the U.S Department of Defense and Department of Veteran Affairs. I'm currently representing a
project that is funded by Veteran Affair's. Our project is to run a database to help patients get the
right help they need and to store their information securely. This falls under rehabilitation and
recovery because we guide them into the correct pathway with our data.
Purpose: Solid State Hard Disk
With high volume of data that we receive, my proposal to The Woodruff Foundation is to upgrade
our work computers with solid state hard disk. Our computers right now have hard disk drives;
which hard disk drive have slow transfer rates. With solid state hard disk we are able to keep fast
transfer rates with high memory capacity and is more reasonably priced than a solid state
drive(SSD). With the huge files we have to deal with our computers right now are slowing down our
performance to do work.

There is very little difference between a laptop and a notebook computer. Notebooks, tend to be
smallest, lighter and as a result, a bit more expensive so the terms are often used interchangeably.
Either way, portable computers typically are more expensive than desktop PCs with equivalent
features. Hand held or palmtop computers are gaining popularity. Although they become more
sophisticated with each new model, palmtops generally have limited features and capabilities
compared to their full–sized counterparts. They are very handy, however for quick tasks when you
are on the road and many include the capability to synchronize and communicate with your primary

Computer Storage History
Computers are amazing. They allow us to play games, take notes, watch movies, and even design
buildings. In order to do these things we need a way to access it in the form of computer storage.
Computer storage is a fundamental component of a computer, it allows us to save and load things.
Storage is space in a computer where data is to be processed and instructions required for processing
are stored. There are two units of memory which is primary storage and secondary storage. Primary
storage is the immediate access store where programs are located while they are running. Secondary
storage is used to hold data that is not currently being executed. There are several different types of
memory that our computer uses such as registers, cache, and tertiary storage. For the purpose of this
essay, we will go over the history or memory. We will focus on the memories past, where it started
and the early advancements. We will also talk about memories present, and how it is used today.
Lastly, we will go over the future of memory and how memory is advancing.
First, we will talk about the memory's past how it started, what are some things that got us to where
we are today. Memory started off all the way back to the ancient Egyptians where they would record
hieroglyphs. When it came to computers, storage started off as more of a physical object than
digital. Memory was in the form of paper with holes punched in it to store information called
punched cards. The computer would read the

The marketing representative should collect insight on different industry needs that are relevant to
hard drives. This information would benefit management more in product development instead of
collecting information on a product that has attributed benefits the market has no need for.
– First the marketing representative should validate market trends, then a cross functional team that
consists of different members with different roles should be assigned to project plan and present
production ideas to management. This division would be led under the Computer Product
Organization´s supervision to create a group with different perspectives. This is the equivalent of
eating like a bird and pooping like an elephant that Kawaski mentions. The team will consume ideas
within and share the outcome with management to make correct decisions. The market research
company was a weak link, as they did not provide them with insight that they didn't already know.
Hence why management might have gotten stuck in a visionary tunnel and not been able to adapt
the product to more use than just focusing on its size.
Define the strategic significance of the disruptive technology
– Ask correct questions that are not solely focused on increasing market shares and becoming the
next cash cow for HP.
– Ask questions that give answers solidifying the value proposition of KittyHawk and the needs of
potential stakeholders. It should be clear to management how they would benefit

computers used to store data in their Random Access Memory (RAM) that was surely not enough to
store large amount of data and was even volatile (temporary). This was the reason Disks were
introduced and now are widely used in our daily life. Background In 1928, Fritz Pfleumer

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).

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

Problems With A Hard Disk Drive Space Essay
If you have been online for any length of time you have run into a few basic computer problems. If
you are like me you do a search on your favorite search engine for the solution to the problem. This
article gives you some simple fixes to common problems computer users run into online. Problem
#1 One problem I run into often is that my computer will occasionally start to run really slow. There
are many reasons this may occur including a hard disk drive which is running short on available
disk space, bad files left from software programs that have been installed or uninstalled, corrupt
data, missing Windows updates or outdated drivers, a computer that is overheating because of a
problem with the fan, corrupt OS, or simply bad Hardware. The solution to a slow running computer
is based on which of the above reasons can be attributed to the problem. To free up hard disk drive
space you can take a few steps to free up space. You should have between 200 and 500MB of free
hard disk drive space on your computer to accommodate swap files and temporary files. To free up
space run "Disk Cleanup", uninstall old programs or games that you no longer use. If you are
running Windows XP or Vista you can disable System Restore, disable hibernation or delete
temporary files. Running Scandisk can insure that there is nothing physically wrong with the hard
disk drive and running Defrag will make sure that the data is arranged in the best possible order. You
may also want to update any

of a Computer Processor A Processor is the 'workhorse' of the computer doing all of the calculations
and processes that are required to power the computer programs that the user are is running. A
processor would find it hard to keep up with all of the most current programs that needed to be run
if it only had one section that could operate. So over time, CPU's have been engineered to have
more than one processor, known a core, so that it can do more things at once, or spread out the
workload. If a processor has 2 cores, it means there are 2 independent cores that can read and
execute commands. It is like two CPU's in one. This means that the processor can achieve much
better performance than if it only had one core. Processing takes power in the form of electricity,
and it gets that from the power from the mains that are in your house or building. This power is then
split up by the power supply, which is plugged into the wall. The power is transferred to the
motherboard using a cable running from the PSU, it is plugged in to the motherboard using a 4 pin,
8 pin, or 4+4 pin connector where the power is transferred through some of the pins where the CPU
connects to the motherboard. The CPU connects into the motherboard by a series of pins or exposed
metal. There are 6 typical ways that the CPU can connect into the motherboard, these are called
called PGA's, or Pin Grid

Windows Desktop Pc : Components And Hardware Description...
Windows desktop PC Component/Hardware Description Motherboard A motherboard is the
arguably the biggest, necessary component of any computer as it is the piece of equipment which
connects all the other components together. This is done by containing many smaller pieces of
hardware, slots and ports. The majority, if not all, motherboards work with processors only from
Intel or AMD. Case and Fans The case of a computer reduces the amount of dust that can access the
components that make a PC, which stops moisture occurring and less damage to the components
and computer overall. Fans are a common component in a PC as it keeps the parts cool and keeps
the amount of dust limited like the case. The most common place for a fan is above the CPU to keep
it cool so it doesn't overheat and cause damage to itself, other components and the computer. PSU
(Power Supply Unit) The PSU is literally what powers the computer. It's typically placed at the back
of a PC rig for easier access for the power cable. The key aspect about computer power supply units
are that they restrict and regulates the amount of power that the computer can actually obtain. This
keeps the computer running smoothly and stops it overheating. CPU (Central Processing Unit)
Without a CPU a computer wouldn't be able to do anything. The CPU of a computer processes
instructions for the other components. It continuously receives input that is then processed into data
and then made into output. This is usually shown on a
