What is a Computer?

An electronic device that processes data to perform various tasks.

Characteristics of a Computer

Features that define a computer's capability, including speed, automation, accuracy, multitasking, storage, connectivity, versatility, diligence, and AI.

1st Generation (1940-1956)

Characterized by the use of vacuum tubes for processing, large size, and slow speeds.

2nd Generation (1956-1963)

Replaced vacuum tubes with transistors, leading to smaller size and faster processing.

3rd Generation (1964-1971)

Utilized integrated circuits (ICs), making computers smaller and capable of multitasking.

4th Generation (1971-Present)

Introduced microprocessors, leading to smaller, faster, and more affordable computers.
