The opportunity this time I will discuss about the hardware. Hardware is a collection components inside the computer that physically can be seen, touched, and felt. Collection of this device can be a computer if it has a linkage structure in each category of performance components.
Computer structure is defined as the way each computer hardware components are connected, start the process of entering data, processing data that has been entered, to generate data information as desired.
The following hardware components and functions:
A. Input devices
Computer hardware that serves as a tool to enter data or commands into a computer, such as keyboard, mouse, scanner, FDD, and optical disk drives (CD-R and RW and DVR-R, Comba, and RW).
B. Output Equipment
Computer hardware that functions as a result of display output data processing. Output can like hard-copy, soft-copy, or sound. Examples include: monitors, printers, and speakers.
C. Process Equipment
1. I / O ports
I / O ports are ports or connectors on installing a gate or place the equipment I / O. Each I / O ports under the control of the processor.
a. Parallel port (LPT1 or LPT2)
Port for equipment that works in parallel with data transmission. Examples of equipment that uses this port is a printer and scanner.
b. Serial port (COM1, COM2)
port for devices that work with serial data transmission. Examples of equipment that uses this port is a mouse and a modem.
c. Port AT/PS2
These ports are generally used to include keyboard and mouse.
d. USB Port
This port is commonly used for digital cameras, camcorders, and Gamepad.
e. VGA Port
Ports that are directly related to the monitor.
f. Audio Port
ports that are directly related to audio, such as tape, radio, speakers, and microphone.
g. Port Games
Ports used to connect Gamepad or joystick.
2. CPU (central processing unit)
CPU is the brain-computer systems, and has two parts, operational functions, the ALU (arithmatical logical units) as a data processing center, and the CU (control unit) as a controller computer work.
3. Memory
Memory is divided into two parts, the internal memory and external memory. Internal memory in the form of RAM (random access memory) which functions to save the program that we though for a while, and ROM (read only memory), which is memory that can only be read and useful as a provider of information on when the computer is first turned on.
4. Data Bus
line transfer of data between modules in a computer system. Because at a certain moment, the channel can only carry one bit of data. The number of channels that can determine the number of bits transferred. Data bus width determines the overall system performance.
5. Address Bus
used to indicate the location of the source or destination of data transfer process. At this point, the CPU will send the memory address to be written or read.
6 Control Bus
used to control the use of and access to the data bus and address bus. Consisting of 4 to 10 parallel channels.
D. Other auxiliary equipment (peripherals)
additional computer hardware that can serve as input or output data (such as a TV tuner, mobile phones, and card reader) can also be used as a sign of media liaison of two or more computers. For example, a modem, network, cards, USB flash disk, tape storage, Firewire, Gamepad / joy stick, bercode reader, microphone, FM tuner, and webcam.
