1)computer: computer is an electronic machine that
1) takes in data and instructions(input)
2) works with the data(processing)
3)puts out information(output).
2)Hardware: The physical components which we can see constitutes hardware.
examples:keyboard, mouse, cpu,speakers, webcam,monitor...etc.
3)Software: Software is a set of programs which is used to perform a particular task.
4)Operating System: Operating system is an interface between user and the system.
examples: windows vista,windows 98, windows NT, windows 2000, linux, unix.....etc.
5)RAM: RAM is an acronym of random access memory.The speed of the system depends upon the RAM.
6)ROM: ROM is an acronym of read only memory.

7)Compiler: Compiler is a software which is used to translate the high level language to machine understandable language.The compiler translates the whole program at a time.
examples: turbo C, Borland C++ ...etc.
8)Interpreter: Interpreter is a software which is used to translate ther high level language to machine understandable language.The Interpreter translates only one line at a time.
examples: Java software
9)CPU: CPU is an acronym of central processing unit
10)Internet: The network of networks is considered as Internet.
11)Scanner: Scanner is an input device which is used to read data into computer.
12)Printer: Printer is an output device which is used to print data on the paper.
13)Monitor: Monitor is an output device which displays the output on the screen.
14)Processor: The Processor is considered as the brain of the computer in the way that it organises and carries out instructions that come from either the user or the software.
15)UPS: UPS is an acronym of uninterrupted power supply.
16)Protocol: Protocol is a set of rules to be followed in order to communicate with other computer through network.
17) Polymorphism: The word polymorphism comes from Greek and means having several different forms. This is one of the essential concepts of object-oriented programming. Where inheritance is related to classes and (their hierarchy), polymorphism is related to object methods.
In general there are three types of polymorphism:
- Overloading polymorphism
- Parametric polymorphism (also called template polymorphism)
- Inclusion polymorphism (also called redefinition or overriding)
18)OOPs concepts:
1)object
2)class
3)encapsulation
4)abstraction
5)polymorphism
6)inheritance
7)message passing
8)dynamic binding19)Inheritance: It is the process by which one object
acquires the properties of another object.SOME SHORT FORMS AND THEIR FULL FORMS:
