COMPUTER FUNDAMENTALS

Detailed explanation-1: -A collection of 8 bits is called a byte and (on the majority of computers today) a collection of 4 bytes, or 32 bits, is called a word. Each individual data value in a data set is usually stored using one or more bytes of memory, but at the lowest level, any data stored on a computer is just a large collection of bits.

Detailed explanation-2: -The correct answer is Binary. Data stored in a compute in the form of binary. A binary number is a number expressed only two symbols: typically “0” (zero) and “1” (one). Each digit is referred to as a bit or binary digit.

Detailed explanation-3: -Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like “h". A kilobyte (KB) is 1, 024 bytes, not one thousand bytes as might be expected, because computers use binary (base two) math, instead of a decimal (base ten) system.

Detailed explanation-4: -Data is stored as files – the computer equivalent of files stored in a filing cabinet. Files are stored in folders and folders are stored within drives. A storage device is a device that is capable of storing and retaining data even when the computer has been switched off.
