Computer Notes for IBPS RRB PO – Overview of Computer Languages

Computers are machines that need to get input to create an output. The input that goes into the computer is not in the language we talk!

  • Computers cannot accept/process data in English language.
  • Therefore, whenever we give any information to the computer, computer converts it into Binary Language, processes it, finds an answer to it and then converts it back to English.
  • A Binary language is a language in the form of ‘0’ and ‘1’.
  • A computer language consists of all the instructions to make a request to the system for processing a task.
  • Any computer language contains codes to give instructions to the machines and fetch an answer from it.
  • Hardware, Machine Language & Assembly Language are low-level languages whereas Fortran, C, C++, JAVA & Pascal are examples of high-level languages.
  • Here is a classification of computer languages mentioned in the above point:  

Let us now understand  the Low-Level Languages in detail.

Computer Notes for IBPS RRB PO – Low-Level Language

Low-level Language is a language understood by the hardware of a computer. It is in the form of Machine Codes. It is the only form of language that the machine hardware understands. Hence, the developers use these languages to write hardware programs.

There are 2 types of Low-Level Language:
⇒Machine Language
⇒Assembly Language

  • Machine Language

    Machine language is the most basic form of language that computers use. The CPU directly processes it. Here, codes are expressed as presence or absence of an electric pulse denoted by ‘0’ & ‘1’ respectively. Machine language expression takes place in bits. For each task, there is a specific instruction expressed in machine codes. As a result, it is generally difficult to understand and translate into human language.

  • Assembly Language

    Assembly Language is the next level of Machine language. It is easy to translate into the machine language & human languages. Hence, when a command is given to a machine in human language, it is comfortably converted into assembly language & further translated into machine language.
