computer language? What is KB, MB?


Computer Language : is a language through which one can communicate with the computer by giving instructions to it. There are three types of computer languages namely, High level languages, Low level languages and Machine level language.

What is Machine Level Language?

The language that is understood by the computer directly is called as Machine language or binary language. It consists of two digits 1 and 0.

High level language is defined as the computer language which Low Level languages (Assembly Language) These are also called as assembly machine independent and resembles English language with a predefined set of rules and symbols.

The examples of high-level languages are Pascal, COBOL, C language, C+. The programs written in high-level language are to be converted into machine language by using compiler so as to enable the computer to understand it.languages.

These are intermediate languages between high level and machine languages. Here a set of codes (Mnemonics) such as ADD, SUB, MUL, DIV are used etc.

Examples : 8085, 8086, 80186, 80286, 80386, 80486, 80586 etc.
This language also cannot be understood by the computer. It should be converted into machine language through a translator program called Assembler. It is dependent on machine architecture.
Bit: Bit stands for Binary Digit. It is either a 0 or a l.
Nibble: A group of 4 bits is a nibble. Example: 1010, 0011, 0000, 111 l etc.
Byte : A group of Eight bits is a Byte. Example : 11001100, 00011100, 11110000, 10101010 etc.
Word: Group of 2 bytes is word. Example: 1111111100000000
KB: (Kilo Byte) 210- (1024) bytes is a KB
MB: (Mega Byte)20 Bytes (2 x 210 Bytes ) - (1024 KB)1024 x 1024 Bytes
GB: (Giga Byte) 230 Bytes 210 MB 210 x 210 KB 210 x 210 x 21 Bytes
TB: (Terra Byte) 240 Bytes -210 GB 210 x 210 MB 210 x 210 x 210 KB 210 x 210 x 0 x 2 Bytes

Note: Each 20 is 1024.
