what is a bit of data?
480902
A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively. Because bits are so small, you rarely work with information one bit at a time.

A bitset stores bits (elements with only two possible values: 0 or 1, true or false , ...). The class emulates an array of bool elements, but optimized for space allocation: generally, each element occupies only one bit (which, on most systems, is eight times less than the smallest elemental type: char ).

The byte is a unit of digital information that most commonly consists of eight bits. The nibble consists of four bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures.

These days, a byte is 8 bits because we say it is. Why 8? Because computers are binary machines and powers of two are handy. A byte is enough to store a single ASCII character plus a “parity bit” which was important back in the dark ages of teletypes, paper tape and so forth.

Data and its types. Data is a set of values of subjects with respect to qualitative or quantitative variables. Data is raw, unorganized facts that need to be processed. ... When data is processed, organized, structured or presented in a given context so as to make it useful, it is called information.

Data is distinct pieces of information, usually formatted in a special way. ... Since the mid-1900s, people have used the word data to mean computer information that is transmitted or stored. Strictly speaking, data is the plural of datum, a single piece of information.

Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary. Processors are all built to work with a set length of bits, which is usually this length is a multiple of a byte: 8, 16, 32, 64, etc.

Megabits per second (Mbps) is used to describe the speed at which digital data travels from one point to another. The capacity of a connection is referred to as it's bandwidth. Bandwidth is measured in bits per second and one Megabit per second is 1,000,000 bits per second.

Data is defined as facts or figures, or information that's stored in or used by a computer. An example of data is information collected for a research paper. An example of data is an email.

Bits are used in computers as small pieces of information assembled into a language that the user can read. Just as bits are the basic blocks of information in your computer, they are used in digital photography to capture an image. Bit stands for "binary device" and refers to the smallest piece of information.

bit pattern. (data) A sequence of bits, in a memory, a communications channel or some other device. The term is used to contrast this with some higher level interpretation of the bits such as an integer or an image. A bit string is similar but suggests an arbitrary, as opposed to predetermined, length.

Bits are usually assembled into a group of eight to form a byte. ... 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. Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB).

In most computer systems, a byte is a unit of data that is eight binary digits long. A byte is the unit most computers use to represent a character such as a letter, number or typographic symbol. Each byte can hold a string of bits that need to be used in a larger unit for application purposes.

A bit (short for "binary digit") is the smallest unit of measurement used to quantify computer data. It contains a single binary value of 0 or 1. While a single bit can define a boolean value of True (1) or False (0), an individual bit has little other use.

Bits are used for computer data because they are easy to represent physically. bits grouped into 8-bit chunks. abbreviated with K, is a collection of 1,024 bytes. ... a program that controls that computer's resources.

Bits can be combined together, usually in powers of two, ie, 8 bits, 16 bits, 32 bits, 64 bits which represent numbers, either integers or floating point. ... A byte is part of a word, that is a 32 bit or 64 bit word can be broken up in 4 or 8 bytes, so each byte would be 8 bits of information.
