Refers to the transmission of digital data between two or more computers.

Refers to information presented in whatever form is agreed upon by the parties creating and using the data.

Means communication at a distance.

The system must deliver data to the correct destination. Data must be received by the intended device or user and only by that device or user.

The system must deliver the data accurately. Data that have been altered in transmission and left uncorrected are unusable.

The system must deliver data in a timely manner. Data delivered late are useless

Refers to the variation in the packet arrival time. It is the uneven delay in the delivery of audio or video packets.

Is the information (data) to be communicated. It can be text, numbers, pictures, audio, video, etc.

The device that sends the data message. It can be a computer workstation, telephone handset, video camera, etc.

The device that receives the message. It can be a computer, workstation, telephone handset, television, etc.

Is the physical path by which a message travels from sender to receiver. Examples are twisted-pair wire, coaxial cable, fiber-optic cable, radio waves, etc.

Is a set of rules that govern data communications. It represents an agreement between the communicating devices.

The communication is unidirectional. Only one of the two devices on a link can transmit; other can only receive.

each station can both transmit and receive, but not at the same time. When one device is sending, the other can only receive, and vice versa.

Both stations can transmit and receive simultaneously.

What are the components of data communication (Separate with space, In order dapat ha)

What are the Fundamental Characteristics of a data communication system (Separate with space, in order dapat ha!)

Is the amount of time required for a message to travel from one device to another.

Is the elapsed time between an inquiry and a response.

Enumerate three network criteria (Separate with space, In order dapat ha)

Provides a dedicated link between two devices. (with dashes)

Are essential in creating and maintaining an open and competitive market for equipment manufacturers and guaranteeing national and international interoperability of data and telecommunications technology and processes.

A _______ connection is one in which more than two specific devices share a single link.

Is the physical and logical relationship of nodes in a network. It is the schematic description of a network arrangement, connecting various nodes through lines of connection.

Type of topologies (Separate with space)

Every device has a dedicated point-to-point link to every other device.

Some of the nodes are connected but only with fewer connections for the same number of nodes.

Every node connects to every other node.

Each device has a dedicated point-to-point link only to a central controller, usually called a hub or a switch.

Every node is attached to one shared bus cable.

Each device has a dedicated point-to-point connection with only the two devices on either side of it.

Is a mixture of two different types of topologies.

A group of computers connected to each other in a small area.

A network that extends over a large geographical area such as states or countries.

a network with a size between LAN and WAN.

Enumerate category networks (Acronyms only separated by space)

Is where task is divided among multiple computers.

Is a set of devices connected by communication links. A node can be a computer, printer, or any other device capable of sending and/or receiving data generated by other nodes on the network.

- means the operating system automatically configures new devices as you install them.
