The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), the first personal computers (PCs) to arrive throughout the 1970s and 1980s had clock rates measured in megahertz (MHz), and in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz).
A chess clock can be used to measure and limit the time taken by each player in a turn-based game. A turn is a segment of a game set aside for certain actions to happen before moving on to the next turn, where the sequence of events can largely repeat.
Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift , caused by clocks counting time at slightly different rates.
Common methods are reducing the clock speed along with the CPU voltage and sending parts of the processor into a sleep state. On processors that have a halt instruction that stops the CPU until an interrupt occurs, such as x86 's HLT instruction, it may save significant amounts of power and heat if the idle task consists of a loop which ...
That is, after some time the clock "drifts apart" or gradually desynchronizes from the other clock. All clocks are subject to drift, causing eventual divergence unless resynchronized. In particular, the drift of crystal-based clocks used in computers requires some synchronization mechanism for any high-speed communication.

The Perfect Scrambled Egg Method. I don't stray from my tried-and-true ratio, but have introduced two big changes: First, the splash of cream is replaced by a small splash of good olive oil.
What determines absolute latency (and thus system performance) is determined by both the timings and the memory clock frequency. When translating memory timings into actual latency, it is important to note that timings are in units of clock cycles, which for double data rate memory is half the speed of the commonly quoted transfer rate. Without ...
