Electronic Numeric Integrator and Calculator (ENIAC)
the transistor was used as the interior sections of the computer.
Second generation computer
When did the third generation computer invented?
1965
he invented the integrated circuit (IC) that was used instead of transistors as the interior sections to build the computer
Jack Kilby
remote processing, time-sharing, and multiprogramming operating system were used.
third generation
when was the fourth generation invented:
From 1971 to 1980
(VLSI)
very large scale integrated
the circuits have about 5,000 transistors and other circuit elements with their connected circuitson a single chip known as the
microprocessor
when was 5th generation invented?
1800 onward
(ULSI)
ultra large-scale integration
enter or send data and instructions from the user or from another computer system on the internet while output devices send back the administered data to the user or to another computer system.
Input Devices
is the most common input device that accepts letters, numbers, and commands from the user.

Mouse
has a ball that can rotate using a finger or the palm of a hand to move the pointer
trackball
is a touch-sensitive pad that lets the user move the pointer by touching and dragging his or her finger on the pad
touchpad
allows a user to speak into the computer to input data and instructions.
Microphone
converts printed material (such as text and pictures) into a form the computer can use.
Scanner
allows one to take pictures then transfer the photographed images to the computer or printer instead of storing the images on a traditional film.
