TECHNOLOGY TIME LINE

Microcomputer

A microcomputer is a computer with a microprocessor as its central processing unit (CPU).

It includes a microprocessor, memory, and input/output (I/O) facilities

Minicomputer

In 1960, Digital Equipment Corporation released its first of many PDP computers the PDP-1

Short for Programmable Data Processor, PDP was a series of computers developed by Digial.

Z1

The ZI was the first programmable computer. The ZI, originally was created by Germany's

Konrad Zuse. The ZI was really the first freely programmable

computer. It is considered to be the first electro-

mechanical binary programmable (modern) computer and its really the first functional computer.

Colossus

The Colossus was the first electric programmable computer.

The Colossus was developed by Tommy Flowers and first demonstrated in December 1943.

The Colossus was created to help the British code breakers read encrypted German messages.

ABC Computer

The ABC computer was the first electronic digital computing device.

Conceived in 1937, the machine was not programmable, being designed only to solve systems of linear equations.

The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and they began constructing it in 1943 and was not completed until 1946.

EDSAC

The first stored program computer. The early British computer known as the EDSAC

is considered to be the first stored program electronic computer.

The computer performed its first calculation on May 6, 1949 and was the computer that ran the first graphical computer game, nicknamed "Baby".

IBM 5100

The first portable computer was the IBM 5100, which was released on September 1975.

The computer weighed 55 pounds and had a five inch CRT display, tape drive, 1.9MHz PALM processor, and 64KB of RAM.

The 5100 series was withdrawn in March 1982.

Osborne I

The first laptop was developed by Adam Osborne in April 1981.

The Osborne I was developed by Adam Osborne and weighed 24.5 pounds, had a 5 inch display, 64 KB of memory, two 5 1/4" floppy drives, ran the CP/M 2.2 operating system, included a modem, and cost around $179 U.S. Dollars.

First Computer Company

The first computer company was the Electronic Controls Company and it was founded in 1949 by J. Presper Eckert and John Mauchly, the same individuals who helped create the ENIAC computer.

The company was later renamed to EMCC or Eckert-Mauchly Computer Corporation and released a series of mainframe computers under the UNIVAC name.

Fastest Computer In The World

The race to build the fastest computer in the world never ends.

Technology keeps improving, microchips keep getting smaller, and processing power continues to massively grow seems technology grows faster each day.
