Ethernet

Ethernet is a standard type of computer network that allows data to be transferred between different devices on a local area network (LAN). It is the most widely used type of computer network for connecting devices such as computers, printers, routers, switches and other network elements.

Ethernet uses data transmission technology using a cable connection. Devices on a network are connected using network cables that transmit data packets in digital form. Ethernet defines a physical layer, which deals with cable and connector specifications, as well as a network layer, which deals with protocols and data transfer methods.

Ethernet networks can be connected using different types of network cables, such as twisted pair (UTP/STP) cables or fiber optic cables. Each type of cable has its own characteristics and limitations that affect data transfer speed and transmission distance.

Ethernet standards are defined by the IEEE (Institute of Electrical and Electronics Engineers) and include various data transfer rates and protocols. Some of the most common Ethernet standards are:

Ethernet (10 Mbps): The original Ethernet standard, which is based on a data transfer rate of 10 megabits per second.

Fast Ethernet (100 Mbps): A faster Ethernet standard that achieves a data transfer rate of 100 megabits per second.

Gigabit Ethernet (1 Gbps): An Ethernet standard that allows data transfer at a speed of 1 gigabit per second.

10 Gigabit Ethernet (10 Gbps): An Ethernet standard with a data transfer rate of 10 gigabits per second.

40/100 Gigabit Ethernet: Ethernet standards for extremely high data transfer rates, reaching 40 and 100 gigabits per second.

Ethernet provides a reliable and scalable method of data transmission in local area networks. It is a general standard that is compatible with different types of devices and provides flexibility for different applications and network requirements.
