Ethernet | Function of Ethernet:

Defination:

  • Ethernet is a communication medium for connecting computers together in a local area network or LAN.
  • It was most widely used method of linking computers together in LANs since the 1990s. The basic idea of its design is that multiple computers have access to it and can send data at any time.

Function of Ethernet:

  • If two computers or devices send data at the same time, a collision will occur. When this happens, the data sent is not usable.
  • In general, both computers will stop sending, and wait a random amount of time, before they try again.
  • A special protocol was developed to deal with such problems. It is called Carrier sense multiple access with collision detection (CSMA/CD).

Is Wifi or Ethernet faster?

Ethernet is a direct connection to your router or modem or modem/router. Ethernet is just plain faster than Wi-Fi because there's no getting around that fact. A wired Ethernet connection can theoretically offer up to 10 Gb/s, if you have a Cat6 cable.

Types of Ethernet Networks:

  1. Fast Ethernet. Twisted pair cable. ...
  2. Gigabit Ethernet. Optic fiber cable. ...
  3. Switch Ethernet. Multiple network devices in a LAN require network equipments such as a network switch or hub.
