Which of the following are not likely to be found on a PC main circuit board?
LCD clocks are not likely to be found on a PC main circuit board.
The CPU requires a fixed number of clock ticks (or clock cycles) to execute each instruction. The faster the clock, the more instructions the CPU can execute per second. Clock speeds are expressed in megahertz (MHz) or gigahertz ((GHz).
Therefore, clock is used to bring some regularity to the system. So, a clock signal is a particular type of signal that oscillates between a high and a low state and it is used to coordinate actions of digital circuits. A clock signal is produced by a clock generator.
