Two key technologies were critical to the first formations of data centres. The first was the advent of personal computers (PCs), which proliferated as Microsoft ’s Windows operating software became the global standard. The second was the development of the network system protocol by Sun Microsystems. Thereafter, microcomputers began to fill out mainframe rooms as servers, and the rooms came to be known as data centres.


Listed below are major milestones in the journey of the big data theme, as identified by GlobalData.

1943 – The UK developed the first data-processing machine to decipher Nazi codes.

1945 – ENIAC, the first electronic general-purpose computer was completed.

1954 – The first fully transistorised computer used all transistors and diodes and no vacuum tubes.

1964 – The IBM System/360 family of mainframe computer systems was launched.

1971 – Intel’s 4004 became the first general purpose programmable processor.

1973 – Xerox unveiled the first local area network (Lan ) at Chase Manhattan Bank , connecting 255 computers.

1977 – ARCnet introduced the first LAN at Chase Manhattan Bank, connecting 255 computers.

1981- The PC era began.
