- 1What is the purpose of a CPUThe CPU processes data and instructions and then passes the data/instructions on
- 2What is the FDE cycleFetch Decode Execute
- 3What happens during the FDE cycleThe computer fetches instructions written in binary, decodes them and then executes said instructions.
- 4What are the three CsCores, Clock Speed, Cache
- 5The Three Cs: What are the coresThe CPU usually contains a number of microprocessors. A core
is a single processor, so a multi-core is multiple processors. - 6The Three Cs: What is a multi-core processorA multi-core processor is an integrated circuit of 2+ processors
for enhanced performance, reduced power consumption and
more efficient processing of tasks. - 7The Three Cs: What is ClockspeedA CPU processes digital data by taking each piece one at a time and
doing something with it. The amount of time that is has to process
each piece is controlled by a quartz clock inside the CPU - 8The Three Cs: One cycle is equal to how many HzOne cycle of a quartz clock is equal to 1 Hz
- 9The Three Cs: how many Hz/s is 180 cycles over 3 seconds60 Hz/s
- 10The Three Cs: What is a cacheCache is a type of computer memory which can be accessed much faster than RAM. The CPU looks in the cache for the data it needs, retrieves it and processes. The cache stores frequently used instructions
- 11Define a computer systema basic, complete and functional hardware and software setup with everything needed to implement computing performance.
- 12The CPU: What does the Control Unit do?It controls stuff, understands instructions and gives orders to other components
- 13The CPU: What is the ALUThe Arithmetic Logic Unit
- 14The CPU: What does the ALU do?It manages maths, logic, and comparisons.
- 15The CPU: What does the Clock do?Manages the number of cycles per second
- 16The CPU: What are the buses?Sets of parallel wires
- 17The CPU: what do the buses do?transport data between components
- 18The CPU: List the registersMAR, MDR, CIR, PC, Acc
- 19The CPU: what does MAR meanMemory Address Register
- 20The CPU: What does MDR meanMemory Data Register
- 21The CPU: What does CIR meanCurrent Instruction Register
- 22The CPU: what does PC meanProgram Counter
- 23The CPU: what does Acc meanAccumulator
- 24What is Secondary Storage?Data storage that does not require electricity
- 25What are the characteristics of Optical Storage?Portable, High Speed, Reliable
- 26What are the characteristics of Solid State storagePortable, Durable, Long Life, Cheap
- 27What are the characteristics of Magnetic storageyes
