It manages the input and output of hardware devices, which include keyboards and mouses, and makes them suitable for the computer. It also creates a record directory structure for the computer and holders the storage space of data vdr for market leaders on long term non-volatile storage area devices. It also helps to control the computer’s memory, making certain it is shared among all operations, and that courses have no more than processing power at any point with time.
