In the early 1940`s only electronic computers, that could use either relays or values, appeared. The first programmable computer was completed in 1941 and was known as electromechanical Zuse Z3 and by modern standards which could be considered as a complete computing machine. During the second world the Colossus was developed so that German messages could be decrypted and it was the first electronic computer. Though it was programmable it could perform only one system and also lacked the capacity of storing information. Also programming was done with the help of many wires, which was not so convenient. In 1956, it was IBM that introduced the first hard disk drive and even today most of the data is stored magnetically on hard disks or on optical media such as CD-ROMs.By the 1990`s a commercialization of international network resulted in wide usage by people for all needs across the globe.
