Computer systems take input and stored data, process it using instructions (software) and then output results.
IOPS Input, Output, Processing & Storage.
Embedded systems are computers built in to other devices like washing machines, dedicated to one task.
Clock speed: each clock tick triggers part of the FDE cycle. So the number of instructions a processor can do in a second is roughly equal to the clock speed
Number of Cores: The more cores a CPU has the more instructions can be done at once. Faster processing.
