In embedded computers, which frequently do not have disk drives, all the expected software might be stored in ROM. Computer software saved in ROM is usually referred to as firmware, because it is notionally far more like hardware than computer software. Flash memory blurs the distinction in between ROM and RAM, mainly because it retains its data when turned off but is likewise rewritable. It is often Substantially slower than typical ROM and RAM nonetheless, so its use is restricted to apps wherever significant velocity is unwanted.[ninety six]

The best computers can complete any of a handful of different Recommendations; the greater complicated computers have several hundred from which to choose, Each and every with a singular numerical code. Because the computer's memory can shop figures, it can also shop the instruction codes. This leads to the significant fact that entire packages (that are just lists of these Directions) may be represented as lists of quantities and may them selves be manipulated inside the computer in precisely the same way as numeric data.

Transistorized computers could consist of tens of A large number of binary logic circuits in a relatively compact Place. Having said that, early junction transistors had been reasonably cumbersome gadgets that were tough to manufacture over a mass-generation foundation, which confined them to a number of specialised applications.[fifty one]
