What is flash memory GCSE OCR computer science? ›
Flash memory is non-volatile memory that can be read from and written to. Flash memory is fast to read from and write to, although not as fast as RAM. It requires little power and contains no moving parts, making it an ideal storage medium for many modern devices such as tablets, smartphones and digital cameras.
Virtual memory enables data that is in RAM and not currently being used to be transferred to the hard disk. This frees up room in RAM for other programs and data. When the data on the hard disk is needed again, any other unused data is transferred to the hard disk before the original data is transferred back to RAM.
