- 1What does CPU mean?Central Processing Unit
- 2What is cache?Cache is a temporary memory
It can be accessed much faster than RAM. The CPU looks in the cache for the data it needs, retrieves it and processes it. - 3What is the slowest memory?Magnetic Tape
- 4What are the function of the CPU?FETCH, DECODE, EXECUTE
- 5What is a multi-core and what are the benefits?Multi-core contains a number of microprocessors. It is an integrated circuit of 2+ processors. This includes benefits such as enhanced performance, reduced power consumption and more efficient processing of tasks.
- 6What is clock speed?Clock Speed is how many processes the CPU can do in a second. 1 cycle per second is also known as 1 Hertz. The faster the clock speed the more efficient the CPU is.
- 7Where does the CPU fetch from? Fastest to SlowestCache, RAM, Hard drive, Magnetic Tape
- 8What is the purpose of a CPU?To complete the processes in the temporary data when the computer first starts
- 9Functions of a CPUOperating System > RAM > Control Unit (if it involves inputs/outputs) > Fetch (RAM/Cache) > Decode (ALU) > Execute > Store > Register
- 10How many levels does each core have?Every core has 2 personal levels and the third level onward is shared between all cores.
- 11Level 1 cacheMemory bank built into the CPU chip
- 12Level 2 cacheSecondary staging area that feeds the level 1 cache
