Answer the following:
1
Write a short note on how data is stored in a computer.​

Answer 1

Answer:

All data in a computer is stored in numbers 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.

Answer 2

Answer:

Computer data may be processed by the computer's CPU and is stored in files and folders on the computer's hard disk. At its most rudimentary level, computer data is a bunch of ones and zeros, known as binary data. Because all computer data is in binary format, it can be created, processed, saved, and stored digitally.

Explanation:

All data in a computer is stored as a number. For example, letters become numbers; the Complete Works of Shakespeare is around 1250 pages in print, contains 40 million bits, with one byte per letter, totalling five megabytes (5MB). Photographs are converted to a set of numbers that indicate the location, colour and brightness of each pixel. Whereas convention numbers use ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9), binary numbers use two digits to represent all possible values. The conventions numbers 0-8 translate into binary numbers as: 0, 1, 10, 11, 100, 101, 110, 111 and 1000. With binary numbers, any value can be stored as a series of items which are either true (1) or false (0).

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. Newer laptops, as well as mobile phones, tablets, USB flash drives and SD cards, use solid state (or flash) storage. With this storage medium, the binary numbers are instead stored as a series of electrical charges within the NAND flash chips. Because all data is made up of a string of binary numbers, just one number out of place can cause a file to become corrupt.
