Some High Level Languages

FORTRAN : 

This language was developed for solving the mathematical formula very quickly and conveniently.

COBOL : 

This language was developed for the commercial purposes.For the processing of this language a group of sentences is selected called paragraph and all paragraphs composed are called a section,while all sections composed are called a division.

BASIC : 

In basic a definite part of the prescribed instruction is only inserted in the computer.

ALGOL : 

This was basically fabricated and designed for the complex algebraic calculations.

PASCAL :

It is an amplified and modified from of ALGOL.

COMAL : 

This computer language is used for the students of secondary level.

LOGO : 

This language is developed in 1973 in France and this language is used for artificial intelligence which is capable and equivalent to the logical program.

FORTH : 

This language was invented by Charles Mure which is frequently used in all types of the work in the computer.

Programming

• Computers perform phenomenal feats of calculation,but they do not do so in a complicated way.
• They actually carry out very simple operations,such as addition and subtraction.
• They achieve their fantastic computing power by carrying out these operations at incredible speed.
• The programme,or set of instructions for operating the computer,is therefore written as a sequence of very simple steps. Several computer languages have been developed for different applications,including BASIC ,COBOL,FORTRAN, and PASCAL.Writing programme is very skilled and time consuming work.
• But for most typical computer applications ready-written programmes are available,called "packages".

Types of Operating System

1. A real - time Operating System is a multi tasking Operating System that aims at executing real time applications.
2. Real - time processing responds to input instantly.
3. An Operating System which allows multiple users to access a computer system concurrently is known as multi user operating system.
4. When the Operating System allows the execution of multiple tasks at one time, it is classified as a multi tasking Operating System.
5. A distributed Operating System manages a group of independent computers and makes them appear to be a single computer. 
6. Embedded Operating Systems are designed to be used in embedded computer systems.
7. Examples of embedded Operating Systems are Windows 10, UBUNTU and Mac 
8. Multi processing Operating System supports running a program on more than one CPU.
9. Multi threading Operating System allows different parts of a single program to run concurrently.

Computer Virus

• The computer is an electronic code which is used to abolish or eradicate the inclusive information or programs of the computer.
• Some important computer viruses are Michelangelo, Dork Avangro,Flip Macmug,Scores,Casecade,Jeruslem,Date crime,Coloumbs crime, Internet virus, Pachcom,Pach EXE, COM-EXE, Marizuana,C-brain,bloody,Chenge Mungu and Desi etc.

Computer networking 

There are two types of networking which are usually occur :

1. Local area networking (LAN)
2. Wide area networking (WAN)

• By LAN all the computers of the same buildings are connected like the computers of university premises,computers of offices etc.
• By WAN all the computers of a large area are connected like the computers of all the offices of a city or town etc.
• In India a very large computer network namely INDONET has been installing through which all the main towns and cities has to be interlinked.

Computer Terminology

Bit : 

The bit is a unit of measurement of the electronic data.One bit is either 0 or 1 but not both. On composing 8 bits, 1 byte is formed.

Bug :  

The bug is the error in the computer program or system and its eradication is called debug.

Byte : 

Total eight bits compose a byte.

Thus 8 bits = 1 byte.

CD- ROM:

A CD like of music CD in which data can be stored substantially called CD-ROM.In a CD with comparison to floppy extremely more data can be stored but one problem in it is that one time recorded data can not be deleted or modified.

Chip: 

It is a thin slice on which by a special mechanism a circuit is designed which is normally made from silicon.

Memory system:

The place where computer data and program are temporarily kept is called memory system.Usually memory is implied from RAM.
