Fundamentals of a Computer

Types of Computer Language

Computer languages are divided as :
1. Low Level Language
2. High Level Language

1. Low Level Language:-

• They are easy to understand by the computer.
• But difficult for programmers to read, write and understand.
• These are of two types :-
  a. Machine Language
  b. Assembly Language

a. Machine Language:-

• A Computer can only understand the Machine Language.
• Machine Language are written in series of 0's and 1's only. (also known as Binary digits)
• It is more difficult to understand and use by the humans.
• The processing speed is very fast. Therefore, most of Games and simulation programs are written in machine languages.

b. Assembly Language:-

• Assembly Language is a symbolic programming language.
• It uses letter codes instead of binary digits.
• These letter codes are alphabetical abbreviation, known as Mnemonics
• For example- For Addition, the Mnemonics ADD may be used.
• Other examples are For Subtraction, the Mnemonics SUB, For Multiply, the Mnemonics MULT, For Divide, the Mnemonics DIV and so on may be used.

2. High Level Language:-

• These languages are also known as Fourth generation languages.
• They are very similar to human languages.
• Therefore, they are easy to read, write and understand for programmers.
• Some languages are C, C++, Java, Phython, PHP, Perl, Fortran, LISP, PROLOG, Pascal, COBOL etc.

Some points to remember :-

• The First computer programming language was created in 1883 by a woman named as Ada Lovelace
• The First Assembly language and Assembler was written by Kathleen Booth
• The C programming language was developed by Dennis Richie
• The C++ programming language was developed by Bjarne Stroustrup
• The Java programming language was developed by James Gosling
• The Python programming language was developed by Guido Van Rossum
• The C programming language was developed by Dennis Richie
• The C programming language was developed by Dennis Richie
