Flow Control

The function of protocols ensures that the transmitting device does not send more data to the receiving device than it can handle.

Addressing

Data communication tasks uniquely distinguish a network node or device over a computer or telecommunications network.

Audio File (e.g., MP3, WAV)

A type of recording that is digitally encoded and stored in any of several formats and can be played using a media player designed to decode the file.

Coaxial Cable

A type of transmission line, used to carry high-frequency electrical signals with low losses.

Data Transmission

The process of transferring data from one place to another or between two locations.

Routing

The function of protocols where it defines the most efficient route between sender and receiver.

Segmentation

The function of protocols where it breaks down a long message into smaller chunks called packets.

Synchronization

Data communication tasks where data are to be exchanged in both directions over a period of time, the two parties must cooperate.

Error Control

These types of rules detect errors in messages and reroute messages to the correct receiver on which the message must be discarded by the receiver and reissued by the sender.

Error Detection & Correction

Data communication tasks required in circumstances where errors cannot be tolerated; this is usually the case with data processing systems.

File Format

The structure in which information is stored or encoded in a computer file.

Interface

Data communication tasks connection and interaction between hardware, software and the user.

Message

The components of data communication in which a piece of information that is to be transmitted from one person to another.

Syntax

Data communication tasks that have to do with an agreement between two parties as to the form of the data to be exchanged or transmitted.

Text Document File

A type of digital, non-executable file that contains letters, numbers, symbols and/or a combination.

Transmission Medium

The components of data communication that is a channel through which the message is carried from sender to receiver, such as twisted pair wire, coaxial cable, fiber optic cable, or wireless.

Efficiency

Data communication tasks that refer the need to make efficient use of transmission facilities that are typically shared among a number of communication devices.

Twisted Pair Cable

A type of cable made by putting two separate insulated wires together in a twisted pattern and running them parallel to each other.

Wireless Transmission

Methods that allow the transmission of data without the use of physical means to define the path it takes.

AVI MP4

A type of file format for storing digital video data on a computer system.

Workstation

A high-performance computer system that is basically designed for a single user and has advanced graphics capabilities, large storage capacity, and a powerful central processing unit.

Coaxial Cable

Refers to the inner conductor and the outer shield sharing a geometric axis.

Internetworking

It allows electronic and digital data to move between two networks, no matter where the two are located geographically, what the data contains, or what format they are in.

Flow Control

A technique used to regulate data transfer between computers or other nodes in a network.

Microwaves

A form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves.

Cell Phone / Mobile Phone

A portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area.

Network Management

Data communication tasks where the process of administering and managing computer networks.

Fiber Optic Cable

The transmission media which refers to the technology that transmits information as light pulses along a glass or plastic fiber.

Access Control

This set of rules makes sure all the network nodes have access to the lines of communication based on priority for example, chronological order of sent messages.

Protocols

The components of data communication which is a set of rules that govern the communication between computers.

Radio Waves

A type of electromagnetic radiation with the lowest frequencies and the longest wavelengths in the electromagnetic spectrum.

Receiver

The components of data communication that is a device that receives messages.

Data Recovery

The process of restoring data that has been lost, accidentally deleted, corrupted or made inaccessible.

Radio Tower / Base Station / Repeater

Usually installed on top of a tall building or on a mountain, and is equipped with an efficient antenna system, so it can receive weak signals and have wide transmission coverage.

Routing

Data communication tasks where it is the process of path selection in any network

Network Security

Policies and monitor unauthorized access, misuse, modification, or networks can be private,

Flow Control

The function of protocols prevents a fast sender from overwhelming a slower receiver by regulating the flow of data, like a traffic controller.

Full Duplex

A two-way communication or bidirectional communication in which both devices can send and receive data at the same time.

Guided Media (Wired)

Referred to as Wired or Bounded transmission media.

Half Duplex

A two-way communication or bidirectional communication in which both devices can send and receive data but not at the same time.

Infrared

Part of the electromagnetic spectrum with a frequency range of 300 GHz to 400 THz.

Sender (Transmitter)

The components of data communication that is simply a device that sends data messages.

Signal Encoding

The properties of the signal, such as form and intensity, must be such that they are capable of being propagated through the transmission system, and interpretable as data at the receiver.

Simplex

One-way communication or unidirectional communication in which one device only receives and another device only sends data and devices uses their entire capacity in transmission.

Telephone Communication

The best example of this data communication are mobile phones, landlines.

Guided Media

The transmission media where signals being transmitted are directed and confined in a narrow pathway by using physical links.

Infrared Radiation

The electronic spectrum used by military and civilian applications include target acquisition, surveillance, night vision, homing, and tracking.
