Ethernet is a type of Local Area Network (LAN) which connects computer in a specific area.
What is Ethernet?
Ethernet is a way of connecting computers over a local network or LAN area. Since the 1990s it has been the most commonly used way of connecting computers within LANs. The basic principle of its architecture is that it is accessible by many devices, and can send data at any time. This is relatively easy to manufacture. This was launched commercially in 1980 and first implemented as IEEE 802.3 in 1983. It helps the system to interact with each other via a protocol which is the common language of the network. This LAN is a network of computers and other electronic equipment that covers a specific area of the office, home, space, or building of your locations.
It is a mechanism that governs the processes of transferring the data through the LAN. This also illustrates how network devices can send and format data packets so that they can be interpreted, processed and accepted by other network devices in the same area network range.

Origin of Ethernet
It was built by Xerox Corporation at its Palo Alto Research Center in California (PARC) between the years 1973 and 1974. The theory was recorded in a report written by Metcalfe in 1973 where he invented it after being postulated by the luminiferous aether to act as a ubiquitous, fully-passive means for the transmission of electromagnetic waves.
The first 10BASE5 Ethernet uses coaxial cable as a communication medium, but in combination with switches, the newer versions use twisted pair and fiber-optic connections. Its data transmission rates have risen over the course of its history from the original 2.94 (Mbit / s) to the latest 400 (Gbit / s).
Different types of Ethernet Cables
Devices with a localized network use wire rather than a wireless connection most likely use Ethernet by using some designated Ethernet cables. Such cables have only a short span and can completely extend and hold ample signals by their longevity. It is the reason that various types of Ethernet cables are used in a given situation to accomplish a specific function. Following are the types of Cables:
- 10Base2: Its a type of a Skinny Ethernet.
- 10Base 5: almost the same as 10Base2.
- 10Base-T: Tangled-pair cable, with a maximum of 10 Mbps
- 100Base-FX: This makes a maximum of 100 Mbps feasible by multi-mode fiber optics.
- 100Base-TX: Close to 10Base-T but at a speed of 10 times more.
- 1000Base-T: Class 5 double tangled-pair cable providing a maximum of up to 1 Gbps.
- 1000Base-SX: This is centered on multimode fiber optics using a small 850 nanometer wavelength transmission.
- 1000Base-LX: It is also based on multimode optic fiber, but use a long wavelength signal.
Types of Ethernet Networks
- Fast Ethernet: This network can transfer data over a twisted-pair or fiber-optic cable at a rate of 100 Mbps.
- Gigabit Ethernet: This network that can transfer data over a twisted-pair or fiber-optic cable at a rate of 1000 Mbps.
- Switch Ethernet: This LAN network that links individual hosts or segments using the switches. The transfer replaces the repeater in the case of individual hosts, which essentially allows the user a maximum of 10 Mbps bandwidth or 100 Mbps for Fast Ethernet to the entire network.
Speed of Ethernet
It can go at various speeds. It had been at 10 MBits per second at the outset. The most commonly used Ethernet currently is at 100 MBits per second. Most modern machines are now fitted in with the NIC and will run at 1GBit per second.
