Cpu - function the cpu is located on the mother board and can
also be called the central processing unit or the processor. In
terms of computing the cpu is the single most important element in
a computer. The cpu is like the brain of the computer it processes
all the machines information.
Slide 4
Cpu-brands There are two main cpu companies intel and amd Amd
cpu,s are cheaper but they have less power Intel costs more but
your paying for more power in a cpu
Slide 5
Cpu-GHz The power for a cpu is usually measured in gigahertz
most computers operate at about 4 gigahertz Some people push cpu,s
to operate at more gigahertz but more on that later
Slide 6
Cpu-cores A core is like a processor inside of another
processor cpu,s can have anywhere from 1 to 8 cores The more cores
you have the faster your computer For example if you have a
computer you will use for video editing you may want to have a 6 or
8 core processor
Slide 7
Cpu- purchasing considerations Cash memory(memory on the cpu)
Compatible with mother board Clock speed Number of cores
Slide 8
Cpu-overclocking Over clocking is when you push you r cpu past
its limitations This sounds great but it can be dangerous for your
computer if you push it too far it could blow up Intel does offer a
partial warranty but for the most part overclocking is not condoned
by cpu companies
Slide 9
Cpu-Hyper threading Hyper threading is a way for the processor
to bring one thing up if you have something else open This feature
is not available on all processors but is a major add on of the
ones that do have it This can be very helpful if used correctly
because it prepares what you will need next
Slide 10
Cpu- my personal choice I would probably pick the intel
i7-377OK The reason for this being that this processor has 4
cores,offers hyper threading and has good performance
Slide 11
Motherboards
Slide 12
Motherboard-function the motherboard is the central part of the
computer where everything meets and is connected.
Slide 13
Motherboard-ram Ram is short for random access memory it is
your computers memory. Ram is located on the motherboard and what
you can do is limited to the amount of ram you have.
Slide 14
Motherboard-form factor Form factors are the 4 different
motherboard sizes. ATX, BTX, micro ATX and mini itx ATX being the
biggest mini itx being the smallest the BTX and the micro atx are
somewhere in the middle.
Slide 15
Motherboard-socket types o The socket is the place where the
cpu will go in on the motherboard. o There are many types of
sockets for motherboards make sure the one you get will be
compatible with the cpu you will use. o Some examples of sockets
are the lga772 or the am2
Slide 16
Motherboards-drive connections There are 3 drive connections
Sata, ide and raid I will talk about each here Sata- the cable used
to connect hard optical and floppy drives to the motherboard Ide-
used to connect drives to the motherboard before being replaced by
the faster, smaller and neater Sata cables. raid- stands for
redundant array of inexpensive disks and allows you to either
combine smaller drives into 1 big drive or use several drives to
mirror or back up data for added security.
Slide 17
Motherboards-expansion slots Expansion slots are used to outfit
your computer with capabilities it might not have been designed
with such as graphics or sound cards.
Slide 18
Motherboards-rear panel ports There are 5 rear panel ports the
Keyboard and mouse ports, the eSATA ports, the Ethernet port, the
USB/FireWire port and the Serial/parallel ports Rear panel ports
are located on the back of the computer case in the rear panel
Slide 19
Motherboard-my personal choice My personal choice would be the
gigabyte GA-Z68M-D2H The reason for this being that it is note very
expensive but it has 4 ram slots and 32 gb,s of memory
Slide 20
Ram (random access memory)
Slide 21
Ram-function Ram is your computer's memory it could not
function properly without it. How fast you can do something depends
on how much ram you have.
Slide 22
Ram-purchasing considerations When buying ram you need to
remember 5 things Quality- good quality ram will work in your
computer for a long time Value make sure you are getting the best
value for the best price Compatibility-will your ram work with your
computer
Slide 23
Ram-when is additional needed If your pc is running slow or
seems kind of sluggish you should probably consider getting more
ram.
Slide 24
Ram-my personal preference My personal choice for random access
memory would be the AD2S800B2G5-R. Because it offers plenty of
memory and people who used it have said good things about it
Slide 25
Video card
Slide 26
Video card-function The video card allows you to see an image
on your computer screen.
Slide 27
Video card-purchasing considerations Here are some things to
keep in mind when shopping for a video card. Graphics processing
unit-determines video capabilities Memory and clock speed Length of
video card- some video cards take up more space
Slide 28
Video cards-my personal choice I would pick the
GTX770-DC2OC-4GD5 I would pick it because people who use it have
given it good ratings and it has 4 gb of storage.
Slide 29

Slide 30
Power supply-function The power supply is the most important
part of the computer with out it nothing works. The power supply
plugs into the motherboard and powers the entire computer.
Slide 31
Power supply-purchasing considerations Things to look for when
buying a psu Wattage Which connectors you need High efficiency
rating Robustness of psu Number of rails Get a modular psu Compare
the amperage of each voltage
Slide 32
Power supply-my personal choice I would pick the antec hcp-1300
platinum It has a good wattage and people who have used it gave it
an excellent rating
Slide 33
storage
Slide 34

Slide 38
Case
Slide 39
Case-why do we need it Cases hold the motherboard and all of
the hardware needed to make your computer work.
Slide 40
Cases-purchasing considerations When buying a case for your
computer there are some things you need to keep in mind. Case
size-there are 3 case sizes mid tower(the most common), full
tower(the biggest) and mini tower(the smallest) each fits different
sized motherboards. Price range- mini towers are less expensive(25
to 80 dollars) but the more expensive full towers full towers can
fit more components if need be however if you spend more money on a
case it will be of better quality You also have to chose between
screws and snap in component areas. Access to components fans built
in etc. The last factor is what you want the case to look
like.
Slide 41
Case-my personal choice I would go with the Aero cool DS-Cube
Blue It is compatible with my components and has good
performance.
