Week 3-session 2-Programming Languages

Programming language is a language for a programmer to communicate with the computer. A computer doesn’t understand the instructions given in English or any other language. So there is a separate set of words, abbreviations and symbols that enables a programmer to communicate instructions to a computer. You can create programs using programming language.



Lower-Level Language

This language is very tedious and time-consuming. Each instruction represents a single machine instruction. This language can only run in particular types of PCs. Here are the two types of lower-level language.

• Machine Language: Uses a series of binary digits or a combination of numbers and letters that represent binary digits.
• Assembly Language: Program is written using symbolic instruction codes called mnemonic. Assembly language must be converted into machine language before the computer can execute the program.

Higher-Level Language

This language is more user-friendly and is a machine-independent language. Each instruction usually represents a multiple machine instructions. This language is very understandable for the programmer.
