An Ethernet port on a laptop computer connected to a twisted pair cable with an 8P8C modular connector Symbol used by Apple and Google on some devices to denote an Ethernet connection Ethernet ( / ˈ iː θ ər n ɛ t / EE -thər-net ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan ...
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system , a port is a logical construct that identifies a specific process or a type of network service .
Ethernet physical layer; ... With rare exceptions, a 100BASE-TX port ... three bits are encoded as two ternary symbols. It is intended for automotive applications.
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
In addition, when the scope of a diagram crosses the common LAN/MAN/WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes. For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted ...
Supermicro AOC-SGP-I2 dual-port Gigabit Ethernet NIC, a PCI Express ×4 card 1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over twisted-pair wiring. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [ 5 ] [ a ] and must use Category 5 cable or better (including Cat 5e ...
Examples of computer connector sockets on various laptops Ports on the back of the Apple Mac Mini (2005). A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment.

Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers . Early Ethernet used various grades of coaxial cable , but in 1984, StarLAN showed the potential of simple unshielded twisted pair .
