What is the cpu (central processing unit) ??
CPU or
central processing unit of a computer is the brain that plays an important role
in a computer or computer hardware also understands and executes commands and
the data from the software. Also cpu serves as a controller and regulator in a
computer. However CPU does not run activities activities as had instructed,
because the CPU has an important part in the CPU part.
The CPU functions
as a calculator function as a calculator but here is the amount of calculation
processing. Its play function is to do arithmetic and logical operations on the
Data retrieved from the memory or the information input into the computer via
the computer hardware (input device). CPU controlled by computer software that
consists of a set of instructions-instructions. The first instruction is stored
in the memory (RAM), where instruction is given instructions by a specific
address of memory called a memory address. Hereinafter CPU can access the data
in RAM to Determine Certain Earlier addresses in the memory.

Devices on
the CPU in the CPU there are several sections and each function is
interconnected items, namely:
Power
supply
Power
supply is a device that is in the CPU the acts as a conduit or flow of
electrical current to all of the computer equipment. Power supply has more than
5 connector that can connect to a variety of computer equipment, such as to:
Motherboard
Hard disk
Floppy disk
drive
CD or DVD
ROM
Motherboard
The
motherboard or main board, the circuit board serves to control the traffic data
of its path so that no collision of data also connects each component on the
computer. The motherboard has systematic path paths that connect one component
to another. On the motherboard there is a slot or socket for input or output
media such as memory slots, processor sockets, etc. pseudo IDE connector to
place the component parts are arranged neatly in a motherboard. And the
motherboard is stored in a box called the CPU or casing.
Harrdisk
The hard
drive is large-capacity storage medium in a computer. Usually there is a file
on the hard disk system and data. Hard drives play consists of three parts.
Namely: a magnetic disc, mechanical parts, as well as the head that serves as a
reader in the hard disk.
As for the
types harddisk
- ATA
- SATA
- SCSI
Processor
Processor
is the brain as a computer controller that is fully supported by the device other.processor is an IC that controls
the overall operations of a computer system to perform calculations and execute
commands from the user (users). Located on the motherboard processor socket that
has been provided by the motherboard. Processor has a huge influence on speed a computer.
VGA card
Vga card is
component of computer
contained on the motherboard socket function displays a visual image to the
screen.
CD or DVD
room
Cd room or
DVDs is unit computer
that can store the data that is frequently used to reinstall the computer.
Data cable
Freshly
prepared roommates a data cable to connect the computer equipment computer
components spayed interconnected and cooperate in running order.
Card LAN
(local area network)
Land card
or a network card that serves to connect one computer to another, can also
connect your computer to the Internet network via tail switch hub.lan card slot
located on the motherboard.
UTP cable
Utp cable
serves as a liaison between computers through LAN card.
RAM (random
access memory)
Ram is a
computer component that serves as a storage medium of data simultaneously
processing user instructions instructions ordered. RAM is temporary so when the
computer is off, the data in the RAM will be lost, unlike room, that the data
will be stored even if the computer is off.
