FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Binary data is primarily stored on the hard disk drive (HDD). The device is made up of a spinning disk (or disks) with magnetic coatings and heads that can both read and write information in the form of magnetic patterns. In addition to hard disk drives, floppy disks and tapes also store data magnetically.

Detailed explanation-2: -There’s a built-in main memory (sometimes called internal memory), made up of silicon chips (integrated circuits). It can store and retrieve data (computerized information) very quickly, so it’s used to help the computer process whatever it’s currently working on.

Detailed explanation-3: -Most systems use some sort of directory/index/registry mechanism to allow the computer to find and access the data. This index/directory will contain one or more keys, and the address the data is actually located in (whether that be hard drive, RAM, database, etc.).

Detailed explanation-4: -The main data storage in most computers is the hard disk drive. It is a spinning disk or disks with magnetic coatings and heads that can read or write magnetic information, similar to how cassette tapes work. In fact, early home computers used cassette tapes for data storage.
