Béda révisi "Komputer"
Modern computers combine many fundamental design features that have been developed by various contributors over many years. These features are often independent of implementation technology. Modern computers derive their overall capabilities from the way these features interact. Some of the most important design features are listed below.
====Digital versus analog====
A fundamental decision in designing a computer is whether it should be [[digital]] or [[analog]]. Digital computers process discrete numeric or symbolic values, while [[analog computer]]s process continuous data signals. Since the [[1940s]] digital computers have become by far the most common, although analog computers are still used for some specialized purposes such as [[robotics]] and [[cyclotron]] control. Other approaches, such as [[pulse computer|pulse computing]] and [[quantum computer|quantum computing]] are possible but are either used for special purposes or are still experimental.
