As digital devices, all cpus deal with discontinuous states, so some basic device is needed to transform and distinguish between these states. Before transistors were accepted by the market, relays and vacuum tubes were commonly used for these purposes. Although these materials are far faster than purely mechanical constructions, they have many unreliable features. For example, building a DC sequential logic loop with relays requires additional hardware to deal with contact jitter problems. Vacuum tubes do not have contact point run-out problems, but they must be preheated before use and must also stop operating at the same time [note 2]. Usually when a vacuum tube fails, the CPU must find the damaged device to replace the new tube. As a result, early electronic vacuum tube computers were faster than electronic relay computers, but they were difficult to maintain. While vacuum tube computers like EDVAC broke down every eight hours, the slower, earlier Mark I was less prone to breakdowns. [2] In the end, however, vacuum tube computers dominated the computing world because of their speed, although they required more maintenance care. Most early synchronous cpus had lower clock rates than more recent microelectronics designs (see discussion of clock rates below). Common clock frequencies at that time ranged from 100,000 Hz to 4 million Hz, largely limited by the speed of the built-in switching device.
