(Lecture 28) Types of Output
(Lecture 26) Multimedia
Multimedia is a combination of sound and images with text and graphics. This would include movies, animation, music, people talking, sound effects like the roar of a crowd, smashing etc.
(Lecture 25) Input Devices
An input device is any hardware component that allows you to enter data or instruction into a computer. Most commonly used input devices are the keyboard, mouse, microphone, scanner, digital camera, and PC video camera.
(Lecture 24) Input
Everything that we give to the computer system through input devices is called input.
(Lecture 23) 4th Generation (1975-Present) Very Large Scale Integration
Small Scale Integration contains ten to twenty I-Cs components. Medium Scale integration, which has hundreds of integrated components in a single chip. Large scale Integration possible to integrate 30,000 components into a single chip. Very Large Scale Integration contains one million components integrated on a single chip.

(Lecture 22) 3rd Generation (1964-1975) Integrated Circuits
Advance "Microelectronic" technology made it possible to integrate larger number of circuit elements into very small (less than 5 mm square) surface of silicon know as Chip or Integrated Circuit. The use of Integrated Circuit in place of transistors gave birth of new generation. They were able to reduce computational time from microseconds to nanoseconds.
Examples: IBM System/360 Series
