DEFINITIONS AND PROPERTIES
Depending on the field of application (mathematics, electronics,
digital technology, computer technology, information theory, etc.), a
bit can be determined in the following ways:1 . In mathematics:1 .1 .
A bit is a single digit of a binary code (a binary digit) can take only
two mutually exclusive values: "yes" or "no", "1" or "0", "on" or
"off", etc.1 .2 .
Corresponds to one numeric digit in the binary number system,
taking the value "0" or "1" ("false" or "true")[4].

IN ELECTRONICS, IN DIGITAL
TECHNOLOGY AND IN COMPUTING
One bit (one binar y bit) corresponds to one binar y trigger (a trigger having two
mutually exclusive possible stable states) or one bit of binar y flash memor y.

4.

IN INFORMATION THEORY
A bit is a basic unit of measurement of the amount of information
equal to the amount of information contained in an experience
with two equally probable outcomes; see information entropy. This
is identical to the amount of information in the answer to a
question that allows the answer "yes" or "no" and no other (that is,
such an amount of information that allows you to unequivocally
answer the question).
One bit is equal to the amount of information received as a result
of one of two equally probable events.

5.

A bit is the binary logarithm of the probability of equally probable events or the sum
of the products of probability by the binary logarithm of probability for equally
probable events; see information entropy.
It is used to measure information entropy. It dif fers from beta for measuring the
volume of storage devices and volumes of digital data, since a large data array can
have very little information entropy, i.e. entropically it can be almost empty.

6.

PHYSICAL IMPLEMENTATIONS
in digital technology, a bit (one binar y digit) is implemented by a trigger
or one bit of flash memor y.
Binar y discharge bit):single-phase ("single-wire") bit (binar y discharge). A
single binar y trigger output is used. The zero level indicates either a
logical "0" signal or a circuit malfunction. A high level indicates either the
signal of the logical "1", or the ser viceability of the circuit. Cheaper than
two-phase implementation, but less reliable;two-phase (paraphase, "twowire") bit (binar y bit).

7.

Both outputs of the binary trigger are used. With a working scheme, one of the two
levels is high, the other is low. A circuit malfunction is detected either by a high
level on both wires (on both phases), or by a low level on both wires (on both
phases). More expensive than a single -phase implementation, but more reliable.

8.

In computing and data transmission networks, the values "0" and "1" are usually
transmitted by dif ferent levels of either voltage or current. For example, in chips
based on transistor-transistor logic, the value "0" is represented by a voltage in the
range from +0 to +0.8 V, and the value "1" is represented by a voltage in the range
from +2.4 to +5.0 V.

DESIGNATIONS
In computing, especially in documentation and standards, the word
"bit" is often used in the meaning of "binar y digit". For example: the
highest bit is the highest binar y bit of a byte or word.
Usage to avoid confusion between abbreviations from "byte" and "bit".
However, it should be borne in mind that there is no abbreviation for
"bits" in the standard, so using the entr y "Gb" as a synonym for "Gbit"
is incorrect.

10.

Minimum values are now practically not used in everyday calculations, but they
allow you to focus on data or make calculations when it comes to professional
applications of developments in the field of computer or information technology.

11.

Based on the comparisons made, it can be concluded that the bit is the minimum of
the possible units used to measure information. A byte is usually called a unit,
which denotes a parameter used for processing digital information and its
subsequent storage. One byte contains 8 bits. When determining the connection
speed, bits are usually used. To determine the download speed of various files —
bytes.
