Circuit

6.Circuit

A circuit is a closed loop of electrical conductors through which an electrical current can flow. It is a basic building block of all electrical and electronic systems, including power distribution systems, communication networks, and computer systems, among others.

A circuit can be as simple as a single conductor connecting two points, or as complex as a system of interconnecting components, such as resistors, capacitors, and transistors, among others. The behavior of a circuit is determined by the properties of its components and the manner in which they are connected.

Circuits can be either analog or digital. Analog circuits are designed to operate with continuously variable signals, such as those that represent sounds or images. Digital circuits, on the other hand, operate with signals that have only two possible values, such as binary ones and zeros, which are used to represent data in computers and other digital devices.

Circuits can also be classified according to the type of current they carry. Direct current (DC) circuits carry electric charges that flow in one direction, while alternating current (AC) circuits carry charges that change direction in a repetitive manner.-Data

Any information (a series of bits) stored on a computer, that makes some sense, or is of some use, can be termed as data.

Data is stored in a defined type. For example, the 'integer' type stores numbers, and the 'string' type is used for a string of text. When data is put together in a structured form it is called a database.
