A collection of flashcards covering key terms and concepts related to computer networks, telecommunications, and business information systems as discussed in Chapter 6.

Telecommunications

The electronic transmission of signals for communications by means such as telephone, radio, and television.

Channel Bandwidth

The rate at which data is exchanged, usually measured in bits per second (bps); broader bandwidth allows for more information to be exchanged.

Synchronous Communication

Asynchronous Communication

Communication where there is a measurable delay between sending and receiving the message, such as emails.

Modem

Router

A device that forwards data packets across two or more distinct networks towards their destinations through a process known as routing.

Centralized Processing

A processing method where all processing occurs in a single location or facility, offering higher control.

Distributed Processing

A processing method where computers are placed at remote locations but connected via telecommunications.

Virtual Private Network (VPN)

A private network using a public network to connect multiple remote locations, providing secure, encrypted connections.

Cloud Computing

A computing environment in which software and storage are provided as an internet service and accessed by users through their web browsers.
