• ICT refers to the technologies that enable humans to connect with one another
• Pre-mechanical Period can be traced back thousands of years ago (3000BCE-450CE)
• Pre-mechanical Period - Early humans realized that stone tablets are too heavy
• Pre-mechanical Period - When papers are produced, strong information was revolutionized
• Pre-mechanical Period - Humans started using the numerical system
• Mechanical Period served as the bridge between our current period and the pre-mechanical period (1450-1840)
• Mechanical Period - steam and gears dominated information processing
• Mechanical Period - Pascaline - A mechanical calculator invented by Blaise Pascal with Wilhem Schickard
• Mechanical Period - Analytical Engine - invented by Charles Babbage, which is considered as the 1st programmable computer
• Electromechanical Period ushered in a new age in communications (1840-1940)
• Electromechanical Period - saw the use of telegraph
• Electromechanical Period - Telephone was invented
• Electromechanical Period - William Cooke invented the first commercial telegraph in 1837
• Electromechanical Period - Samuel Morse introduced the first circuit telegraph in 1884
• Electromechanical Period - Alexander Graham Bell was granted the patent for the telephone in 1876
• Electronic Period is the last period in ICT (1940-Present)
• Electronic Period - 4 Main Events: The Late Vacuum Tubes Period, The Transistors Period, The Integrated Circuits Period, The Computer Processors Period
• Electronic Period - Vacuum Tube Machine Period - The latter period of the vacuum tube machine is the start of the electronic period
• Electronic Period - ENIAC stands for Electronic Numerical Integrator and Computer
• Electronic Period - ENIAC was the first electronic and general purpose computer
• Electronic Period - Transistor Period - Transistors were invented in 1974, it is an electronic device similar to vacuum tubes
• Electronic Period - Transistor Period - in 1950, the first transistor was developed
• Electronic Period - in 1958, Jack Kilby was credited for introducing integrated circuits
• Electronic Period - Integrated circuits are device that is composed of a group of transistors
• World Wide Web enables you to access hypertext
• World Wide Web was proposed by Tim Berners-Lee in 1989
• Three Types of Web: Web 1.0, Web 2.0, Web 3.0
• Web 1.0 is a read only web
• Web 2.0 is a read and write web
• Web 3.0 is a semantic execution web
• Social Media - Applications started together with Web 2.0
• Social Media contains different formats
• The effectiveness of social media applications is measured by its virality
• Web Search Engines are programs designed to search
• Research Indexing Sites are websites dedicated to compile
• Massive Online Open Course (MOOC) Sites are websites dedicated to teach
