                                                   DEFINITIONS OF COMPUTER

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

                                                                                                       

PART OF COMPUTER

1.      SOFTWARE

Software is a collection of some of the commands or instructions are executable by a computer to work on it as needed.

The types of software:

1. Operating systems: a software that connects between humans and computers. Example: Windows, linux, android.

2. Utility program: a software that serves to maximize computer performance. Example: Antivirus.

3. Application program: the software used to program the sesai certain functions. Example: Winamp, adobe photoshop, nero.

4. Compiler or interpreter: the software that serves to translate the program into machine language. Example: Microsoft visual basic.

2.      HARDWARE

Hardware is the physical part of the computer all, and distinguished from the data it contains or operates on.

Example of hardware :

1.2  Input

Input device is a device that is used to enter commands and data to be processed . Input devices commonly used in the computer are :

·         Keyboard : Is an input device that is used to enter letters , numbers and special characters.

·         Mouse : Is the input device that serves to move the pointer or cursor quickly.

·         Microphone : Function to record or insert sounds into the computer

webcam.

·           Scanner :Scanner is used to scan the image / file.

2.2  Process

CPU is the most important part of a computer because it is the brain of the computer . CPU often also called the microprocessor or processor called data processing and compute. Process  devices commonly used in the computer are :

·           CPU (Central Processing Unit)

CPU is the most important part of a computer .because it is the brain of the computer . CPU often also called the microprocessor or processor called data processing and compute.

·           Memory

RAM / ROM Memory is a computer hardware whose function is to store the information before or after processing by the processor . Such information may include the command or data .

Memory is divided into 2 ( two ) parts , namely Internal Memory and External Memory called ROOM ( Read Only Memory ) .

A. RAM ( Random Access Memory )

RAM is the memory that is used to store temporary data on a command or program sebuarun . The command includes the data to be read from disk.

B. ROM ( Read Only Memory )

ROM is used to store data in fixed order .as the name implies , the computer can only read data and commands contained in ROM ,

such as commands that run when you first turn on the computer.

 

·               Motherboard

Motherboard or mainboard is often referred to as a computer device that serves as a repository for other devices , such as Memory , Processor , VGA Card , Sound Card , LAN Card and others.

·               Hard Drive

Hard drive is a storage medium with the greatest capacity .hard drive is used for the purpose as a repository of data used computers.

·   VGA Card

VGA Card is a computer device that functions signal transform digital signals into images .

·      Sound Card

Sound card is a computer peripheral that functions convert digital signals into sound signals . Sound Card allows the data in digital form is displayed in the form of sound on the speakers .

3.2  Output

The output device is a computer device that is used to display commands and data that has been processed .input devices commonly used in the computer are:

·         Monitor

Monitor function to display the data , instructions and information in the form of text , or image engraving.

·         Speaker

Speaker serves generating or sound effects from your computer .

·           Printer

The printer is an output device that is used to print the data / information from the computer to paper.

3.      BRAIN WARE

Brainware can be interpreted as an intellectual device (in this case human brain) who operate and exploration capabilities of the hardware and software available.
