Ethernet Switching Modes
Ethernet is one of the most popular networking architecture for LANs. It can offer high performance, low cost, and it is also easy to install and manage. The work of the IEEE 802.3 committee defines the standards of Ethernet and there are also various Ethernet implementations that can support any business’s needs. This paper will distinguish the basics between channels and circuits, Ohm’s law, and network protocols. Network protocols will also be defined against communications failures and what type of technology would businesses benefit from. Lastly, current available systems, enhancements, additional opportunities, and network architecture will be discussed.
Basics between Channels and Circuits
A channel is a medium used to carry signals. The channel may be free space, a copper cable, a fiber optic cable, or a combination of all three. In general, channels are exposed to noise that may corrupt the information that they carry. As each channel exhibits different characteristics, they become affected by noise differently. Information signals can be strengthened by means of suitable devices so that information is transferred in an acceptable form.
A circuit is a path that is between two or more end points which flows electrical current. In data communication, a circuit is considered as a specific path that is between two or more end points that carries along a signal that can be either analog or digital. The physical path of the circuit may consist of one or more wires and can also be wireless as well. The difference between a circuit and a channel is basically the way that it is utilized. A channel is a portion of the circuit that is used to transmit a single voice or data signal, which can be either a 4 kHz signal in analog transmission or 64 Kb/s signal in digital transmission (Thakur, n.d.). Many channels together can also be contained within a circuit found in WAN technology
