Languages to be Aware of

Machine code

• Least abstracted Language

• Closest to what happens in a computer

• Directly done in binary

Assembly

• Use mnemonics

• Each mnemonic matches a specific sequence of machine code

• Written in assembly before being translated by a specific assembler

High Level Languages

• Each instruction can translate into multiple machine code instructions

• Provides high abstraction, making programming easier

• Easier to read, write, and maintain, but relies on a compiler or interpreter to convert code into machine code.

Imperative

• Use statements that change a program’s state (e.g. selection, iteration and sequencing)

• Contains commands for the computer to perform

• Focuses on describing how a program operates

• Currently in the specification

Declarative

• Focuses on what the computer should accomplish, rather than detailing how to do it.

• The program describes the desired results or logic, leaving execution steps to the computer.
