CPU

1. Performance

   • Cache is small but fast memory inside the process where instructions are stored temporarily meaning the storage is volatile
   • Clock speed is the rate at which the computer ticks. So the higher the clock frequency, the faster the CPU can run and the more instructions that can be processed every second.
   • Cores is the amount of tasks the computer can perform at any time. If you are to have multi-cores they will be able to work simultaneously.

2. Components

   • Arithmetic logic unit (ALU) is a component inside of the CPU and handles the data processing inside the CPU. This deals with number problems within the computer system
   • Control Unit has three main jobs which are to control how data moves around a system.It executes the instructions provided by the program (control signals). It controls and monitors the flow of data between the CPU and other components such as input devices, memory, graphics card etc (signals to memory/devices)
   • Registers are used to hold temporary data while a software program is running. As the CPU processes the data, the software program will shift the data in and out of the registers.
