clock tick
Same as a cycle, the smallest unit of time recognized by a device. For personal computers, clock ticks generally refer to the main system clock, which runs at 66 MHz. This means that there are 66 million clock ticks (or cycles) per second. Since modern CPUs run much faster (up to 3 GHz), the CPU can execute several instructions in a single clock tick.

The process used on some older 486 computers to triple the internal processing speed of the CPU while maintaining the manufacturer’s original clock speed for I/O transfers. In most cases, clock-tripling would normally yield a lower than 100 percent overall system performance boost (e.g., 30 to 70 percent), not an actual tripling of the clock […]
