Question

state the name of the five special purpose computer used for diagnostic application​

Answer 1

Older cell phones/telephones, had computing capacity but most was directly involved with the telephony process.

Televisions, intended to recive and translate a signal into a picture.

The processors in your new car's engine, they are very specific and control many regulated functions in the motor and electrical systems.

Game consoles. Although becoming more generalized computers these days, the older ones only ran games and not much else, unless hacked to do so

NASA supercomputers, they are great for heavy number crunching and simulation, but not much else. Don't expect top tier graphics, gameplay or networking.
