Network media refers to the communication channels used to interconnect nodes on a computer network. Typical examples of network media include copper coaxial cable , copper twisted pair cables and fiber-optic cables used in wired networks, and radio waves used in wireless data communications networks.
The IEEE 802.21 standard for Media Independent Handoff (MIH) is an IEEE standard published in 2008. The standard supports algorithms enabling seamless handover between wired and wireless networks of the same type as well as handover between different wired and wireless network types also called media independent handover (MIH) or vertical handover.
Wired communication refers to the transmission of data over a wire-based communication technology (telecommunication cables). Wired communication is also known as wireline communication . Examples include telephone networks , cable television or internet access , and fiber-optic communication .
Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1 ]
Wireless communication (or just wireless, when the context allows) is the transfer of information (telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.
A wireless access point (WAP) connects a group of wireless devices to an adjacent wired LAN. An access point resembles a network hub, relaying data between connected wireless devices in addition to a (usually) single connected wired device, most often an Ethernet hub or switch, allowing wireless devices to communicate with other wired devices.
There are two main types of transmission media: guided media—waves are guided along a solid medium such as a transmission line; unguided media—transmission and reception are achieved by means of an antenna. One of the most common physical media used in networking is copper wire. Copper wire to carry signals to long distances using ...
In particular, separate models are formulated to describe each layer of a communication system. A channel can be modeled physically by trying to calculate the physical processes which modify the transmitted signal. For example, in wireless communications, the channel can be modeled by calculating the reflection from every object in the environment.
