First generation computers were built with vacuum tubes. The capabilities were about the same as that of modern computers, except limited by very small memories and slow speed. Typical first generation computer memory cost from $2 to $20 per byte equivalent, whereas today's computer memory costs less than a micro-penny per byte.

History of computer is divided into 5 generation. The first generation of computer started form 1941 till 1956. In this generation vacuum tubes are used in computers and computers are big enough that one computer could be such big as a whole room.

The first generation of computers:

  • used vacuum tubes
  • were large
  • consumed lots of power
  • usually operated in batch mode
  • most did not yet have operating systems
  • etc.

That would be a computer that was entirely mechanical.

Historians like to compare certain kinds of cloth weaving equipment to mechanical computers.

The first generation computers are normally considered to be the ones built with vacuum tubes and span the time period from the early 1940s to about 1958 when transistorized computers (e.g. IBM 7090) appear.

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

1st generation computers used vacuum tubes for data processing and were very large in size. These vacuum tubes generated a lot of heat and used up a lot of power.

5 difference of 4th generation of computer and 5th generation of computer?

This is hard to answer, because there is no industry standard for what a 'generation' is. It is entirely subjective. You will need to define a 'generation' before a comparison is given. IE, there are 3 generations of AMD Phenom II processor, and over 70 generations of AMD processors. There are five major generations in processor bitrate. There are over 400 generations of individual progressments in major computer technology. There are nearly 50 different generations of individual architecture design.
