STRAND 1.0: FOUNDATION OF COMPUTER SCIENCE

SUB-STRAND 1.1: EVOLUTION AND DEVELOPMENT OF COMPUTERS

1.1.1 Early Computing Devices (Relating to Electronic Computers)

These early tools, though not electronic, introduced fundamental concepts in computation
and paved the way for the development of modern computers.

(a) Ancient and Medieval Computing Devices

✔ Abacus (Around 2400 BC)

Description: A manual calculating tool consisting of beads arranged on rods or wires, representing place values. Operators manipulate the beads to perform arithmetic operations.

Relation to Evolution: Introduced the concept of representing numbers using physical objects and performing calculations through manipulation—an early form of data processing.

✔ Napier’s Bones (Early 17th Century)

Description: A set of numbered rods used for multiplication and division. The rods contained pre-calculated multiples of numbers, simplifying complex calculations.

Relation to Evolution: Showed how pre-calculated information and structured tools could simplify mathematical tasks—a step toward automated computing.

✔ Pascaline (1642)

Description: The first mechanical calculator capable of addition and subtraction. It used gears and dials to represent numbers and perform calculations automatically.

Relation to Evolution: Marked a major step toward automated calculation using mechanical principles—a precursor to electromechanical devices.

✔ Slide Rule (Around 1620)

Description: An analog computer used mainly for multiplication and division, as well as roots, logarithms, and trigonometry. It uses two logarithmic scales that slide against each other.

✔ Difference Engine (Early 19th Century)

Description: A mechanical calculator designed by Charles Babbage to automatically calculate polynomial functions. It was intended to produce accurate mathematical tables and eliminate human errors.
