Coaxial cable is a type of cable that has an inner conductor surrounded by an insulating layer, surrounded by a conductive shielding. Many also have an insulating outer jacket The diagram below illustrates the construction of a typical cable. Electrical signal flows through the center conductor.
Coaxial cable is a type of transmission line, used to carry high-frequency electrical signals with low losses. It is used in such applications as telephone trunklines, broadband internet networking cables, high-speed computer data busses, cable television signals, and connecting radio transmitters and receivers to their antennas.
What kind of communications device sends and receives data and information to and from a digital line such as ISDN and cable?
An ISDN modem sends digital data from a computer to an ISDN line and back. A DSL modem sends digital data from a computer to a DSL line and back. A cable modem, or broadband modem, is a digital modem that sends and receives digital data over the cable television network.
Which network type connects each computer and device to a central device such as a hub or a switch?
Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.
Which statement best describes how the RFID standard works?
Which statement best describes how the RFID standard works? The network uses radio signals to communicate with a tag placed in or attached to an object, animal, or person.
What is the most important device for information communication?
A computer is the most important device used in information communication, which is considered to have gone through five generations since it was created. It has application in several fields such as telecommunication, robotics, diagnostics etc.
What is data communication hardware?
Data communications equipment (DCE) refers to computer hardware devices used to establish, maintain and terminate communication network sessions between a data source and its destination. DCE is connected to the data terminal equipment (DTE) and data transmission circuit (DTC) to convert transmission signals.Nov 26, 2018
RelatedWhich topology is best?
A full mesh topology provides a connection from each node to every other node on the network. This provides a fully redundant network and is the most reliable of all networks.
RelatedWhich network type connects each computer and device to a central device?
Star network topology -- The most common network topology, star topology connects each device in the network to a central hub. Devices can only communicate with each other indirectly through the central hub. Hybrid network topology -- Any combination of two or more topologies is a hybrid topology.
