- 1How to increase the performance of a computer?Increasing Ram:Allows more programs to be opened and rely on virtual memory less
Upgrading Secondary Storage:Changing it to a SSD for faster read/write speeds - 2Why does Cache affect CPU performance?It allows the CPU to access frequently used instructions than going to RAM/Secondary Storage because cache is quicker
- 3Name 2 registers:Program Counter:Stores the address of the next instruction to be executed
Accumulator:Stores the intermediate results of a calculation
Intermediate:Most recent and fresh result - 4State the function of a embedded systemA embedded system is a computer system built into another device with one main function E.G.Co trolling temperature
- 5How do computers convert audio into a fileIt records the analogue sound that is is targeted at. It is then measured at amplitudes during intervals which is then turned into a sample of sound.Each sound has its own unique binary code and id converted
- 6What happens when a sample rate is increased?The quality of the audio is higher and is more accurate to the actual sound.Because more samples are taken and it has a higher quality the file size will increase
- 7Difference between Lossy and Lossless compressionLossy compression reduces the file size and the data is lost permanently whereas in lossy compression the file is reduced but the data can be added back so it isn’t permanently removed
- 8Explain what a right shift doesEvery time a right is performed the number is divided by 2.If the number is right shifted twice the number will only be a quarter the size of true original

- 10Advantages and Disadvantages of a client serverAdvantages:Can set user access levels,can update all devices at once, all files are stored in one location.This is because all devices connected are controller by the server
Disadvantages:If the server fails the whole network collapses,expensive to maintain and can also have hardware issues.If some of these happen then all the users feel the effect
