Computer Systems & Computer History

Input is...

• when the computer accepts the information and converts it into data

• when a user physically puts information into a computer

• when the computer returns the processed information to the user

• when the computer remembers the data so that it can be used later

In 1890, Herman Hollerith invented the first electronic computing machine, which was known as...

• the tabulating machine

• the Harvard Mark 1

• the Magnavox Odyssey

• the enigma machine

In 1947, Bell Laboratories invented the transistor. Why was this important for computers?

• It allowed computers to connect to the Internet.

• It allowed computers to be made smaller.

• It allowed computers to be on a single circuit board.

• It allowed computers to play video games.

In 1959, ​ (a)   invented the microchip, which made it possible to have an entire computer on a single circuit board.

• Jack Kilby
• Herman Hollerith
• Steve Jobs
• Tim Berners-Lee
