What you'll learn

Each question helps you build key knowledge and skills.

  • 1Hardware and software must work together: an operating system, which is software, manages the hardware resources such as the CPU, memory and storage devices.
  • 2Inside the CPU, the program counter, memory address register and memory data register work with the control unit and ALU to move instructions through the fetch decode execute cycle.
  • 3CPU performance depends on several factors together, including clock speed measured in hertz, the number of cores, and the size of the cache, not just one factor alone.
  • 4Memory can be arranged in a hierarchy: registers are fastest but tiniest, cache is fast and small, RAM is larger but slower, and secondary storage is largest but slowest.
  • 5Secondary storage technologies differ in speed, capacity, portability and cost: solid state drives are faster than magnetic hard disks, while optical discs and cloud storage suit different purposes.
