The Mainframe Computer • Are powerful iron computers • Saves as much data as the census, statistics, resource planning, and more. • Houses the CPU.

Microcomputers • Were popular in the late 1970’s and early 1980’s but was made in the 1960’s. • The Microcomputer usually came with at least one type of data storage which was usually RAM.

RAM • Before RAM computers used relays or delay lines for memory. Ultrasonic delay could only reproduce written data in order. • First form of RAM was Williams tube in 1947 storing data as electrically charged spots on the face.

The First Megabit • IBM uses first Megabit. • Stores up to 1 million bits of information.
