FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -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-3: -Data (information) is stored in a computer as files.

Detailed explanation-4: -Computer Data Representation Most references to computers use the number of bytes as a measure for the computer’s memory (primary storage) capacity and storage (secondary) capacity. Each cell stores a specific amount of data called a word (e.g., in our class, we will usually use examples using 8 bits.)

Detailed explanation-5: -The Binary system is a number system which uses bits to store data. A bit is a “binary digit”, the smallest increment of data on a machine. A bit can hold only one of two values: 0 or 1. Because bits are so small, you rarely work with information one bit at a time.
