The first computer developed in Europe was the EDSAC (Electronic Delay-Storage Automatic Computer). This machine was built at Cambridge University in 1949.
What characterized these earliest machines is that the switching and control functions were handled by vacuum tubes. This feature typifies what is termed the first-generation of computers. EDSAC had one feature that ENIAC lacked. Within the computer was stored the instructions to control the machine and the data to be operated upon. This was the first of the stored program computers. The first commercially available digital computer was the Sperry Rand UNIVAC I. This was sold to the Bureau of the Census and put in place in 1951.
In the late 1950's the bulky and hot vacuum tubes were replaced in computer designs by smaller, more reliable solid state transistors. The use of transistors as the basic component of computer design characterizes what is known as the second generation of computers.
1963 brought about the start of third-generation computers. Solid-logic technology (SLT) enabled the development of the integrated circuit (IC). ICs allowed the placement of as many as 6
