Second Generation computers. The VAX mentioned above is just a single model of first generation electronic computers.
The first home computers could do anything any other computer could, if you could fit it in their tiny memories.However the first electronic computers in the 1940s and 1950s had exactly the same problem, very tiny memories.
the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.
VACUUM Tubes were first used as Logical Components in firstmanufactured Computers. Then the Invention of Transistors changed the Computing Industry and now the miniature form of Transistors ranging in nanometers (for e.g. 65nm or 45nm based processors).
The Colossus computers used at Bletchley Park during World War II, for cryptanalysis purposes, are widely acknowledged as the first programmable digital computers. Technically, the word 'computer' means 'one who computes', and doesn't refer to a machine, but rather people who were employed down the ages as 'computers' to decide on a persons tax liability.

No, they were not.
All early electronic digital computers were made using standard off-the-shelf Radio components, these components had been made since before the 1920s, with some dating back to the 1700s in early forms. The first high reliability vacuum tubes made specifically for electronic digital computers were made in about 1949.
The first generation of electronic computers were those implemented using vacuum tubes.
first generation computers were not fast and were less reliable.

The first electronic digital computers were developed between 1940 and 1945 in the United Kingdom and United States.
