EVOLUTION OF ICT

Mechanical Period

1450-1840; development of machines to enhance calculating speed; Pascaline and Analytical Engine

Electromechanical Period

1840-1940; electricity for information handling and transfer; 1st single-circuit telegraph and telephone

Electronic Period

1940-present; gave rise to solid-state devices

Analytical Engine

1st programmable mechanical computer; Ran off of punched cards; Created by English mathematician and computer pioneer Charles Babbage, but never completed by him.

Pre-Mechanical Period

3000 BCE- 1450 AD; humans started to communicate; petroglyphs, papers, books and libraries were born, humans started using numerical systems, abacus

telegraph

A device that used electrical signals to send messages quickly over long distances. Invented by Samuel Morse and gave rise to the Morse Code

Graphical User Interface (GUI)

Allows users to navigate other computers or devices

telephone

Converting sound into an electrical signal via a liquid transmitter

solid state devices

ENIAC, Olivetti Programma 101 (1965), IBM 5150 (1981), Xerox 8010

Charles Bourseul

Frenchman who invented telephone-like devices on 1854

ICT

Information and Communication Technology

Pascaline

Invented by French Mathematician-Philosopher Blaise Pascal, first ever calculating machine to be produced in quantities and is actually used; first business calculator

Alexander Graham Bell

Invented the telephone, won the first US patent for the device on 1876. He began his research in 1874 and had financial backers who gave him the best business plan for bringing it to market.

Antonio Meucci

Inventor of the telephone in 1849

Four Main Periods of ICT

Pre-Mechanical, Mechanical, Electromechanical, Electronic Period

Alfred Vall

Samuel Morse's assistant whom he sent the first message to

Analytical Engine

The Father of computer

abacus

a calculator that performs arithmetic functions by manually sliding counters on rods or in grooves, first calculating device

Morse Code

a system of dots and dashes that represent the alphabet.

Solid State Devices (SSD)

also known as electronic devices

IBM 5150 (1981)

created by a team if engineers led by Don Estridge, the first desktop computer with monitor and uses Command Line Interface

petroglyphs

drawings, symbols carved on rocks

Xerox 8010

first GUI (Graphical User Interface)

ENIAC (Electronic Numerical Integrator and Computer)

first electronic general-purpose computer that can solve full-range of computing problems, originally designed for the US Army for artillery

"what hath God wrought!"

first sent message through the telegraph

Olivetti Programma 101 (1965)

invented by Pier Giorgio Perotto, world's first personal computer, first desktop computer without monitor

Command Line Interface (CLI)

used to operate softwares and operating systems
