Computer Language

To communicate with the computer user also needs to have a language.

Low level language: - Low level computer languages are machine codes or close or close to it. It can only understand and execute instructions given in the form of machine language i.e. language of 0 and 1. There are two types of low level language.

1) Machine language: machine language is basically the only language which computer can understand. Its machine code which is represented inside the computer by a 0 and 1. The symbol 0 stands for the absence of electric pulse and 1 for the presence of an electric pulse.

Advantage:

  • It makes fast and efficient use of the computer.
  • It require no translate the code i.e. directly understood by the computer.

Disadvantages:

  • All operation codes have to be remembered.
  • All memory address have to be remembered.
  • It is hard to a or find error in a program written in the machine language.
  • These language are machine dependent.

2) Assembly language: It operation codes and operands are given in the form of alpha numeric symbols instead of 0’s and 1’s.

Advantages:

  • It is easier to understand and use as compared to machine language.
  • It is easy to locate and correct errors.
  • It is modified easily.

Disadvantages:

  • Like machine language it is also machine dependent.
  • Since it is machine dependent therefore programmer should have the knowledge of the hardware also.

High level language: Each instruction in the high level language is translated into many language instruction this showing one to many translation.

The earliest device that qualities as s digital computer is the abacus also known as sabosan this devices permits the users to represents number by the position of beads on a rack. Another manual calculating devices was john nophier bone. Charles Babbage a nineteenth century professor at Cambridge University is considered to be the father of modern digital computer. Babbage designed a different engine in the year 1882 which could produce reliable tables. In 1842 Babbage comes out with his new idea of analytical engine that was intended to be completely automatic. It was capable of performing the basic arithmetic function for any mathematical problems and it was to do so at an average speed of 60 additions per minutes. It was very complex in design and huge in size. It used over 3000 electricity actuated switches to control its operation and was capable of performing was approximately 50 feet long and 8 feet high. It was five basic arithmetic operation additions, subtraction, m...
