A clock not only needs to be read, it must be set, too. An instrument other than a watch for measuring or indicating time, especially a mechanical or electronic device having a numbered dial and moving hands or a digital display. The clock frequency of a CPU is normally determined by the frequency of an oscillator crystal. Clock properties realtime It is intended to represent the real time, and thus it can be translated in some way to and from calendar representations (see to_time_t and from_time_t member functions). The clock speed is measured in Hz, typically either megahertz (MHz) or gigahertz (GHz). It is usually measured in MHz (Megahertz) or GHz (Gigahertz). See more. Clock definition is - a device other than a watch for indicating or measuring time commonly by means of hands moving on a dial; broadly : any periodic system by which time is measured. It is usually measured in MHz (Megahertz) or GHz (Gigahertz). The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. Clock properties realtime It is intended to represent the real time, and thus it can be translated in some way to and from calendar representations (see to_time_t and from_time_t member functions). The accuracy determines how close the clock is to an official time reference like UTC. A "timesharing clock" interrupts the CPU at regular intervals and allows the operating system to divide its time between active users and/or applications. Clock rate means the number of pulses generated by CPU in one second. A PC’s clock speed is an indicator of its performance and how rapidly a CPU can process data (move individual bits). Clock speed is measured by how many ticks per second the clock makes. Can you spell these 10 commonly misspelled words? Accessed 20 Dec. 2020.
