KNOW YOUR COMPUTER
BEFORE you use the computer, you should know first
advance what is called the computer. The introduction of this important
so that we can use the computer with the best possible way
highly efficient and effective.
Computer Systems
Generally, what people call a "computer" is a set of
tool consisting of CPU, monitor, and keyboard. There are also
which states that the CPU was the one who called the computer, while
Other tools are complementary, with its own name
such as monitors, keyboards, mouse, printer and others.
Actually, the notion of computers are more accurately called as
computer system. Computer system consists of three devices (devices),
namely:
hardware (hardware),
software (software), and
Man (brainware).
The tools mentioned above is an example of the hardware.
Computer systems can not run only with one
device, but requires all three.
Chapter 1
Hardware
Computer hardware that we know can be classified into three
group:
input devices (input devices);
Devices processor (processing unit);
The device output (output device).
Input device is equipment that we use to enter
data to a computer, such as keyboard, mouse, and scanner.
Processing devices are devices that perform data processing
into information, or who becomes "brains" of computers in the machine
execute the command given. Processing devices are often
called a CPU (central processing unit / central processing unit) or called
also the processor.
Output devices are devices used to display
information processed by computers, such as monitors, printers, and speakers.
From the above it can be concluded that the often mentioned
CPU is actually a part of computer processing
data (processor), a chip, and is known by the name
brands such as Intel Pentium, Intel Celeron, AMD Athlon, and so forth.
Figure 1. Computer hardware
The "body" (casing) computer which is called the CPU not only
contains a processor, but also contains the mainboard (or
also called mother-board), diskette drives, CD drives, hard drives, memory
(RAM), VGA cards, sound cards, LAN cards (also called Ethernet
cards), modems, and so forth.
