OCR 2023 COMPUTER SCIENCE H046/01: COMPUTING PRINCIPLES AS LEVEL QUESTION PAPER & MARK SCHEME (MERGED)

OCR Systems are designing a new CPU for a computer system that will be used for video rendering. Part of the video rendering process is when the video is exported. This is when the computer combines all of the separate video elements together to form the final video. (a) Describe two factors that affect the performance of the CPU. 1 ................................................................................................................................................ ................................................................................................................................................... ................................................................................................................................................... ................................................................................................................................................... 2 ................................................................................................................................................ ................................................................................................................................................... ................................................................................................................................................... ...................................................................................................................................................

[2] 4 OCR 2023 (ii)* A storage device is used to store the individual video elements while they are being captured in different locations and during the video editing process. Discuss the suitability of a flash storage device and a magnetic storage device for storing the different video elements while they are being collected and edited. You should refer to the following in your answer: • the benefits of each type of storage • the drawbacks of each type of storage • the suitability of each type of storage.
