Typically an analog computer whose signals are represented by varying vacuum levels. One common use of these was in gasoline powered vehicles (where the carburetor supplied vacuum) and they controlled things like timing advance and cruise control. Electronic digital embedded control computers have made these obsolete.
One could build digital computers that represented binary values as vacuum (1) or no vacuum (0), but I have never heard of any.
Perhaps you left out a word and meant "What is a vacuum tube computer?". These were the first generation digital computers, built from the 1940s to ~1958 when transistors replaced vacuum tubes in digital computers.
the vacuum tube
It used 5200 vacuum tubes.
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.

A computer mini vacuum is useful as it allows you to hoover all of the dust and dirt from the keyboard and the monitor and ensures that the computer is dust free. Dust can cause problems for computer circuits so its recommended to hoover your pc regularly
This must be a vacuum hose, with a connection to the intake manifold, at rear of carb. This must be an after-market distributor because the original "Lean Burn" computer did not have a vacuum advance distrib. The vacuum was connected to the computer that controlled the distrib. advance. these setups, one made by Mopar, kit #P3690426, by passed the computer and is vacuum operated.

ENIAC
The prototype for the Atanasoff-Berry computer was demonstrated in October 1939, it used 11 vacuum tubes. The full Atanasoff-Berry computer (the first electronic digital computer) was finished in early 1942, it used 280 vacuum tubes, 31 thyratrons, and was about the size of a desk.
That transmission is all computer controlled. No vacuum lines on it.
Idle speed is not adjustable. If the speed is incorrect you have a computer, sensor, actuator, vacuum leak issue.Idle speed is not adjustable. If the speed is incorrect you have a computer, sensor, actuator, vacuum leak issue.
