A medical imaging facility needs to store and archive thousands of high-resolution MRI scans on their central servers. To save storage space, they are deciding whether to compress these files using a lossy or a lossless compression algorithm.
Compare using a lossless compression algorithm with using a lossy compression algorithm for this purpose.
Practise Edexcel GCSE Computer Science Data storage and compression with exam-style questions for GCSE Computer Science. 50 questions covering Binary multiples and file size calculations and Need for and methods of compression, matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
