COMPUTER FUNDAMENTALS

Detailed explanation-1: -Saved files are stored on a computer’s hard disc. The hard drive is a data storage system that uses magnetic storage to store and receive digital data with a rapidly spinning disc coated with magnetic material. In 1956, the hard disc was introduced and quickly became a popular secondary computer storage unit.

Detailed explanation-2: -How is data stored on a hard disk? Data is stored on a hard drive in binary code, using 1s and 0s. The information is spread out on the magnetic layer of the disk(s) and are read or written by the read heads that ‘float’ above the surface thanks to the layer of air produced by the ultra fast rotation of the disk.

Detailed explanation-3: -A hard drive is a critical component of many computers. The device stores your programs and data regardless of whether your PC is turned on or off. It’s considered semi-permanent storage because while any data on a hard drive should last for years without failure, no digital storage system is perfect or permanent.

Detailed explanation-4: -Hard Disks Nonvolatile storage is physical media that retains data without electrical power. This means that no data is lost when the computer is powered off, making hard disks suitable for permanent storage of information.

Detailed explanation-5: -RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
