Understanding Computer Time Units, CPU Cycles and Performance Latency
The article explains that software performance is measured in milliseconds to nanoseconds, describes core hardware components—CPU, caches, and DRAM—shows how cache hierarchy speeds differ, defines a clock cycle as the basic time unit, and provides typical latency figures for operations ranging from a single CPU cycle to a full system reboot.
