The CPU
Clock speed - how fast the processor can fetch,decode and execute in one second:
-
-
-
-
Eventually if the clock speed gets too fast your program will start to work slower and it will eventually crash
-
The CPU is an electronic machine that works on a list of computer things to do, called instructions. By fetching, decoding and executing each instruction
A central processing unit (CPU) is an important part of every computer. The CPU sends signals to control the other parts of the computer, almost like how a brain controls a body.

Cores
By having more than one core, the CPU can process more than open instruction at once depending on the amount of cores it has

Two personal computers (PCs) are advertised with different hardware specifications. PC A has a quad-core processor with a clock speed of 2GHz. PC B has a single core processor with a clock speed of 4.1GHz. 3 (a) Explain which processor you think is likely to run instructions more quickly---------------------------------------------
PC A is quicker as it had 4 quads working with it meaning it can do 4 things at once rather than being very quick but still is moderately quick because if something is too quick it may crash whereas if it is slower but has more quads it makes it better.
CPU Cache Memory is used to store instructions or data that are either frequently used, have recently been used or about to be used.
By having more Cache Memory its helps the CPU as it has more information to help it work an instruction out and it is quicker as the information is closer stored
