Creation of Z1 Computer
The Z1 was a mechanical computer designed by Konrad Zuse from 1935 to 1936 and built by him from 1936 to 1938. It was a binary electrically driven mechanical calculator with limited programmability, reading instructions from punched tape.
The Z1 was the first freely programmable computer in the world which used Boolean logic and binary floating point numbers. -
ABC Computer
The Atanasoff–Berry Computer (ABC) was one of the first electronic digital computing devices. Conceived in 1937, the machine was not programmable, being designed only to solve systems of linear equations. -
First Barcode with Linear Patterns
On 20 October 1949 Woodland and Silver filed a patent application for "Classifying Apparatus and Method", in which they described both the linear and bullseye printing patterns, as well as the mechanical and electronic systems needed to read the code. -
First Electronic Calculator (14-A calculator)
The Casio Computer Company, in Japan, released the Model 14-A calculator in 1957, which was the world's first all-electric (relatively) "compact" calculator. It did not use electronic logic but was based on relay technology, and was built into a desk. -
Spacewar Computer Game
Spacewar is one of the earliest known digital computer games. It is a two-player game, with each player taking control of a spaceship and attempting to destroy the other. -
Magnetic Tape
This is a long plastic tape coated with iron oxide for use in magnetic recording. Data stored on magnetic tape is accessed sequentially, therefore if you want to access data at address 1500 you first must go through the 1499 address before. Magnetic tape is still used today to create batch ups of important company data. -

Hard Disk Drive (HDD)
A standard component of any computer nowadays. The first was 3.5-inches in sizes could store 10MB. A hard drive has rotating platters on a motor-driven spindle within a protective enclosure. Data is magnetically read from and written to the platter by read/write heads that float above the platters. They can store audio, video, text and images. -
Google
Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California. -
USB 2.0
Stands for Universal Serial Bus and it was designed to standardise the connection of computer peripherals such as mice, keyboards, digital cameras, printers. USB's have no moving parts and are therefore robust and reliable. They are also very portable and can store text, images
etc.
