What is ethernet
Ethernet is a networking protocol that is used to connect computers and other devices over a local area network (LAN) or a wide area network (WAN). It is based on the OSI (Open Systems Interconnection) model, which divides networking into seven layers, with each layer responsible for a specific set of functions.
At the physical layer, Ethernet uses a variety of technologies to transmit data over a network, including twisted pair cables, coaxial cables, and fiber optic cables. It also uses a variety of media access control (MAC) methods to determine how devices on the network access the shared medium and transmit data.
At the data link layer, Ethernet uses a number of protocols to ensure that data is transmitted reliably between devices on the network. These protocols include the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol, which is used to prevent devices from transmitting at the same time, and the Address Resolution Protocol (ARP), which is used to map IP addresses to physical addresses.
At the network layer, Ethernet uses the Internet Protocol (IP) to route data between devices on the network. It also uses a variety of other protocols, such as the Internet Control Message Protocol (ICMP) and the Internet Group Management Protocol (IGMP), to manage and control the flow of data on the network.
Overall, Ethernet is a widely-used networking protocol that is used to connect computers and other devices over a LAN or WAN, and to transmit data between them. It is used in a variety of applications, including data transfer, telecommunication, and internet access.

Overall, Ethernet uses a variety of different protocols and technologies to support the transmission of data over a network, and to ensure that it is transmitted reliably and efficiently.
Ethernet cables are used to connect computers and other devices to a local area network (LAN) or a wide area network (WAN). There are several types of Ethernet cables that are commonly used, including twisted pair cables and fiber optic cables.
Twisted pair cables are the most common type of Ethernet cables, and are made up of two insulated copper wires that are twisted together. These cables are available in several different categories, including Cat5, Cat5e, Cat6, and Cat6a, which are differentiated based on their performance characteristics and the frequency of the signals they can support.
Fiber optic cables are also used in Ethernet networks, and are made up of thin strands of glass or plastic that transmit data using light signals. These cables are known for their high-speed and long-distance capabilities, but are more expensive and fragile than twisted pair cables.
Ethernet cables are available in a variety of lengths and connector types, including standard connectors such as RJ-45 and fiber optic connectors such as SC and LC. The specific type of Ethernet cable and connector that is used depends on the specific requirements of the network and the devices being connected.
Overall, Ethernet cables are an important part of a network infrastructure, and are used to transmit data between devices and to connect devices to the network.
"Platforms established on an EtherNET foundation have become increasingly popular in many sectors of industry. This technology, which is both practical and offers time/place savings, has evolved and branched out over time and has been embedded in third-party platforms as well.
