HISTORY OF COMPUTER AND PROGRAMMING LANGUAGES

What is Computer?

• A machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming

• A set of instruction following the rules of the chosen language

• A set of words, symbols and codes that enables a programmer to give instruction to a computer

• A set of instruction that tells a computer to perform tasks

What is Computer Program?

• A machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming

• A set of instruction that tells a computer to perform tasks

• A set of words, symbols and codes that enables a programmer to give instruction to a computer

• A set of instructions following the rules of the chosen languages

Advantages of Low-Level Language

• Programs are lengthy

• Instruction are readily understood by the computer

• Instruction are easier to learn compared to machine language

• Ready for immediate execution

• Machine-independent

Disadvantages of Assembly Language

• Not readily understood by the computer, thus need to be translated to machine language before executed

• Programs are lengthy

• Have to be converted to machine language before they can be executed

• Instruction are extrememly cryptic and difficult to learn

Machine language is a collection of ______ ______ or bits that the computer reads and interprets.

Low-Level Language

A single instruction corresponds to ___ operations at the machine level.
