What are the types of programming languages?

1. High-Level Languages (Close to human language) (source code)

2. Low-Level Languages:

a. Machine Code (Consist of only 0s and 1s — binary)

b. Assembly Language (Use mnemonics — short abbreviations)

  1. High-level languages:

Close to human language.

Easier to debug due to natural language.

No knowledge of hardware is needed.

Portable and not designed to run on just one type of machine.

Examples: C++, Java, Pascal, Python, Visual Basic.

2. Low-Level Languages: Assembly and Machine

a. Machine Code:

Consist of only 0s and 1s — binary.

CPU understands directly

Very difficult to write and debug due to binary.

Each number represents a different instruction.

b. Assembly Language:

Between machine code and high-level language.

Use mnemonics — short abbreviations- like “INP” (input a number =>operand: 00000000)

Can make use of special hardware or special machine-dependent instructions.

Requires less memory.

The program that converts source code into machine code (object code) is called translator.

Three types of translator:

Compilers: Convert source code into machine code at a once.

Interpreters: Convert source code into machine code line by line.

Assemblers: Convert assembly language into machine code.
