In communications, a simplex communication link is one way only, and a duplex link goes in both directions. An example of a simplex link is a satellite beaming a signal to a receiver dish where the communication only goes in one direction, from the origin to a receiver. An example of a duplex link is a telephone.Know More
Most duplex communication links have two links: one to transmit and one to receive. A half duplex link can both receive and transmit, but it cannot do both at the same time. An example of a half duplex link is a walkie-talkie. The person talking on a walkie-talkie cannot receive while talking.
The same terminology can be used in other fields. An electrical circuit with one wire set up such that the current can only flow one way is a simplex link. Simplex fiber-optic cables have only one fiber-optic relay inside them, and duplex fiber-optic cables have two fiber-optic relays inside them.
The same terms have been borrowed for use in printing and scanning, but the terms are used somewhat incorrectly. Printers may offer the option of duplex printing, namely printing on both sides of the paper, or simplex printing, on only one side of the paper. Duplex scanners scan both sides of the paper, and simplex scanners scan only one side.Learn more about Internet & Networking
A Simple Network Management Protocol port is a network communications channel. Administrative computers use SNMP to monitor equipment attached to a network. In an SNMP setup, a software agent constantly reports information about the network via SNMP to the administrative computer.Full Answer >
The difference between narrowband and broadband is that narrowband communications use a smaller bandwidth range than wideband communications. Additionally, in terms of access to the Internet, narrowband connections provide data at a slower rate, while broadband connections offer a higher data rate. Narrowband and broadband, or wideband, are terms which refer to the amount of bandwidth used to transfer information.Full Answer >
Internet Protocol Security, often written as IPSec, is the process in which communications over a network are secure with encoded authentication. It defends the IP packets and prevents network attacks. Data and identity is breached without proper security implementation, granting intruders unauthorized access.Full Answer >
IPv6, short for Internet Protocol Version 6, is a next generation communications protocol created by the Internet Engineering Task Force to replace the current IPv4. Because Internet traffic requires unique sender and receiver addresses and the number of users has grown exponentially, more addresses are required than IPv4 can support.Full Answer >
