Solution
The correct option is D LCD clocks
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.
