The Boot Sequence- sequnce of processes, containing all the information to get the computer up and running.
After booted the control is handed to the operating systems.
The speed of the CPU depends on :
CPU Clock Speed- determined by the electric clock chip.
- Measured in cycles per second- Hertz (Hz)
- Processor speeds are measured in gigahertz (GHz)--- billion cycles/ second
Cache Memory = expensive
Number of Processor Cores- Multi-cores have multiple cores working together.
The CPUs can fetch----decode-----exectute instructions at the same time.
- More data processed simultaneously
- However complocated operating systems are needed to manage them.
