Computer - A programmable machine that has two principal characteristics: 1. It responds to a specific set of instructions in a well-defined manner. 2. It can execute a prerecorded list of instructions (a program).
Note: The actual machinery of a computer (e.g. Processor, Monitor, Keyboard, wires, etc.) is called hardware and the instructions and data are called software

Components of a Computer:
All general-purpose computers require the following hardware components:
memory : Enables a computer to store, at least temporarily, data and programs.
mass storage device : Allows a computer to permanently retain large amounts of data. Common mass storage devices include disk drives and tape drives.
input device : Usually a keyboard and mouse, the input device is the conduit through which data and instructions enter a computer.
output device : A display screen, printer, or other device that lets you see what the computer has accomplished.
central processing unit (CPU): The heart of the computer, this is the component that actually executes instructions.


COMPUTER WORKSTATION:
Computer Hardware - any part of the computer you can touch.
Processor
Memory
Wires
Transistors
Input/Output Devices
Storage Devices


Software - electronic instructions to the computer. Also referred to as a “program.”
Two types:
1. System Software
2. Application Software

SYSTEM SOFTWARE:
Operating Systems
Windows XP / Windows Vista
Linux
Mac OS

Application Software:

Word Processing – MS Word, WordPerfect ..
Spreadsheets – MS Excel, Quattro Pro, ..
Databases – Ms Access, MS Works Database,..
Publishing/Graphic Design – MS Publisher, Corel Paint, ..
Presentation – MS PowerPoint, WP Presentations, ..
Digital Applications – Adobe, Corel Photo-Paint,..

TYPES OF COMPUTERS
Computers can be generally classified by size and power as follows, though there is considerable overlap:
1. Supercomputer,
2. Mainframe,
3. Minicomputer,
4. Microcomputer.

The fastest type of computer.

1. SUPERCOMPUTER
Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations.

For example, weather forecasting requires a supercomputer.

Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration.

2. MAINFRAME
A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously.
In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs.

3. MINICOMPUTER
A midsized computer.
In size and power, minicomputers lie between workstations and mainframes.
In general, a minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.

4. MICROCOMPUTER

A small, relatively inexpensive computer designed for an individual user.
In price, personal computers range anywhere from a few hundred dollars to thousands of dollars.
Businesses use personal computers for word processing, accounting, desktop publishing, and for running spreadsheet and database management applications.
At home, the most popular use for personal computers is for playing games.

TYPES OF MICROCOMPUTERS
Desktop - often called a PC
Laptop - also called a Notebook
Palmtops - Personal Digital Assistants (PDA)
