What examiners said
Most candidates were able to identify that the first description was of a MAC address. Few candidates were able to recognise that the final description was of a core. Few candidates were able to provide accurate descriptions of a register, clock and the control unit. Candidates need to have technical understanding of the role of key components in the CPU.
