Processor
Processor manufacturer The manufacturer that produced the processor.	Realtek
Processor family A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.	Realtek
Processor model The model number for the processor in a computer.	RTD1619B
Processor frequency The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions.
