Processes that are not synchronized, allowing for actions to happen independently at different times. Frequently used in computing and networking to refer to data transmission where operations occur independently.
BAUD is a measurement of the speed of a modem, specifying the number of times per second a communications channel changes the carrier signal sent on the phone line. It is often confused with bits per second (BPS), though they are technically different measurements.
Broadband is a high-capacity transmission method that provides multiple channels of data, voice, or video over a single telecommunications medium, commonly used for high-speed Internet connections like cable and DSL. It allows for simultaneous transmission of voice and data over the same line, standing in contrast to traditional dial-up connections.
Electronic Data Interchange (EDI) refers to the use of electronic data-transmission networks to move information from one computer system to another, typically without human intervention. This technology is widely used for automating orders, invoices, and payments between suppliers, customers, and banks, among other applications.
Encoding refers to the process of converting information or a message into a specific format or code, often to ensure confidentiality, efficient transmission, or storage.
Ethernet is a standard method of connecting computers to a Local Area Network (LAN) primarily using coaxial cable, but also other forms of cabling and link media.
Fiber optics are tiny cylindrical strands of glass or plastic used for data transmission. They carry light rather than electrical energy, enabling vast data transfer with minimal interference.
The process of moving or transmitting a computer file from one location to another, such as between two programs or from one computer to another, ensuring data integrity and confidentiality.
In computer usage, full duplex refers to the transmission of data in two directions simultaneously, allowing for more efficient communication.
In telecommunications, half duplex is a mode of transmission wherein data can be sent in only one direction at a time. This means that at any given moment, a device can either transmit or receive data, but it cannot do both simultaneously.
Infrared (IR) is a type of electromagnetic radiation with a wavelength longer than visible light but shorter than radio waves. It is commonly used for data transmission in devices like TV remote controls, wireless mice, and keyboards.
A telecommunications technology offered by telephone companies that provides transmission speeds up to 128Kbps. ISDN can simultaneously transmit voice, data, and video over the same line and requires specialized equipment including a network terminator and an ISDN adapter.
An interface is a point of interaction between different data processing devices, systems, or components, allowing them to communicate and operate together. Interfaces can handle data exchanges, convert signals, and ensure effective connectivity and interoperability.
A jack is a connector into which a plug can be inserted, facilitating the connection and transmission of electrical signals, data, or power between different devices.
A modem is a device that links computer systems via telephone lines, enabling computers in different locations to exchange information. It is short for modulator-demodulator. Modems convert telephone impulses to computer-interpretable impulses, requiring a modem at each end of the communication link to send or receive converted impulses.
A packet is a unit of data sent across a network. When a large block of data is to be sent over a network, it is broken up into several packets, which are then sent separately and reassembled at the destination.
A parallel port is an output device that allows a computer to transmit data to another device using parallel data transmission—several bits sent simultaneously over separate wires. PC parallel ports are usually designated as LPT1, LPT2, and so on. This is in contrast to a serial port, which transmits data sequentially, one bit at a time.
Parity is a method used in computing and telecommunications to check whether data has been transmitted or stored correctly by ensuring an odd or even number of bits.
Satellite communication refers to the use of orbital satellites to transmit voice, data, video, and graphics from one location to another.
The transmission of messages by computers, telephone, telegram, or television. It involves the exchange of information over significant distances by electronic means and refers to all types of data transmission. It is fundamental in modern communication systems, supporting conversations, internet browsing, video conferencing, and broadcast TV.
Videotex, also known as viewdata or interactive videotex, is a revolutionary system wherein information is transmitted via telephone lines between a computer and a TV screen, allowing for interactive data entry and retrieval.
