Aim:
To draw a computer layout and mark
the positions of SMPS, Motherboard, FDD, HDD, CD / DVD drive and add on cards
Procedure
Motherboard
The
motherboard has been an integral part of most personal computers for more than
20 years. The motherboard contains various circuit cards performing various functions
all plug into many similar sockets on a common circuit board. Each circuit card
performs a unique function in the computer and gets its power from the socket.
The motherboard contains many circuits and slots, but let’s focuses on some of the
important ones. The motherboard is home to the processor (CPU) along with the
access slots and RAM.
If we
look at the diagram above I've labeled the parts of the motherboard that I
wanted to discuss. The objects labeled 1 are the access slots. 2 is the
processor slot and 3 are slots to hold memory (RAM).
CPU
The
CPU, or processor, is the heart of your computer no matter what type (PC,
Server, and Laptop). There are many brands for processors such as Intel and
Athlon all with different processors for your computer. The CPU processes
everything that your computer does, therefore the better the processor, the
faster the computer.
RAM
Random Access Memory (RAM) is the form of memory contained in most computers.
RAM is considered "random access" because you can access any memory
cell directly if you know the row and column that intersect at that cell. When
an application is running it stores its information in the RAM. When you close
the application the information is deleted from the RAM. This is why you need
certain amounts of RAM to run applications. The more RAM you have the faster
your computer will be, and the more applications you'll be able to run without
losing speed.
Hard Drive
Nearly every desktop computer and server in use today contains one or more
hard-disk drives. These hard disks do one thing well - they store changing
digital information in a relatively permanent form. They give computers the
ability to remember things when the power goes out.
A hard drive stores all your files and information in a permanent form unlike
storing it in RAM (which is temporary). The larger your hard disk (drive) the
more information and files you're able to store. Today's average hard drive is
40 GB although slowly 80 GB hard drives are becoming used more often.
CD-Rom
The CD-Rom is quite simple, it reads CD's. CD-Rom completely stands for Compact
Disk Read Only Memory. The revolution of CD's is that they hold much more data than
a floppy disk, although are not as flexible when it comes to rewriting and
storing personal data.
Using CD-RW you can make your own CD's and use them more like a floppy disk.
These are becoming more and more popular although you still need a CD-Rom to
read them.
Floppy Drive
A floppy drive reads the popular floppy disk. Floppy disk is easy to use,
rewritable, compact, and great for storing information. The floppy drive is
simple and allows you to read, write to, and write over information stored on a
floppy disk.
Power Supply
The power supply is vital to the computer as it is the source of power. The
power supply is usually a small metal box in the top corner of a case (tower).
You can see the power supply in both diagrams. How the power supply works isn't
too important, but if you wish to know you can visit howstuffworks.com
(external link).
Access Slots
Access
slots or expansion slots are openings in a computer where a circuit board can
be inserted to add new capabilities to the computer. Examples of drives that
may go here would be modems; USB drives, networking cards, video adapters, and
sound cards. These expansions are easy to install along with being very useful
to your computer to allow you to do new things, such as network computers
together.
Result:
Thus the pc
layout was drawn and the internal parts are indentified
