First generation computers were characterized by the fact that operating instructions were made-to-order for the specific task for which the computers was to be used. Each computer has a different binary-coded program called a machine language that told it how to operate. This made the computer difficult to program and limited its versatility and speed. Other distinctive features of first generation computers were the use of vacuum tubes (responsible for their breathtaking size) and magnetic drums of data storage. The computers during the period 1945 – 1956 are regarded as the First generation computers.

6th generation computers are available or not ? Any one find 6th generation computers?
no;but I will like to know if its out.
first generation computers have realy been proved inefficient in its operation compared to what we have today.
These may seem hopelessly bulky and slow now, but in their time were considered miraculous. Computers like this were instrumental in winning World War II by helping to break Axis radio codes.
