It depends on how you define 1st generation.
The earliest computers were mechanical, and the size of a fairly large room. We then had electrical computers, like the Enigma encryption device, about the size of a large typewriter.
1st generation electronic devices were quite big - about 4 filing cabinets, with the first generation of 'home' computers being about the size we have now, but using CRT monitors.

∙ 7y agoThe first generation (i.e. vacuum tube) computers varied in size from filling much of a large room (e.g. Colossus, ENIAC, UNIVAC I, IBM 701, AN/FSQ-7 SAGE Air Defence Computer) down to roughly the size of an office desk (e.g. Atanasoff-Berry Computer, Librascope LGP-30). The AN/FSQ-7 SAGE Air Defence Computer was the largest computer ever built (and each site had two of them to provide fault tolerance) using 49000 tubes in just the computer and filling an entire floor of a four story windowless concrete building (one floor for power supplies and air conditioning systems, two floors for the two computers, one floor for the computer "terminals" and the officers using them).

Why are the fourth generation computers called digital computers?
Because the first, second, and third generation computers were also digital computers.
History of computer Before 1st generation of computers?
Electro-Mechanical Computers were used before first generation of computers.
Was a Microcomputer part of the first generation?
no, first generation computers used vacuum tubes.
What happened to the speed of computers as they moved from first generation to fifth generation?
The speed of computers increased from one generation to the next generation, and to the next generation, and so on.
What are the first generation computer?
First Generation computers were computers made out of Vaccum Tubes. They were soon rejected due to the extreme heat and electricity absorption.
First generation computers are called ICL2900HP9845 A VAX11780.What are second generation computers called?
Second Generation computers. The VAX mentioned above is just a single model of first generation electronic computers.
What are first generation computers?
By most definitions, first generation computers were the ones built with vacuum tubes.
What generation was the minicomputer first used?
The first minicomputers were second generation computers, but the most well known minicomputers were third generation computers.
Why are the fourth generation computers called digital computers?
Because the first, second, and third generation computers were also digital computers.
What sizes of memory were available on first generation computers?
from less than 1000 words to 32000 words on scientific computers.from less than 20000 characters to 80000 characters on business computers.
What are features for second generation computer?
Second generation computers are often called transistorized computers. The transistorized computers are more advanced computers than the first generation of computers.
