Ethernet - Fast and Gigabit Ethernet

This description of Ethernet explains the purpose of Ethernet, Ethernet standards and the terminology of hardware components.

Ethernet cards are network adapters designed to support personal computers and other host devices. Ethernet cards are available in ISA, PCI, PCMCIA, and USB form factors.

An Ethernet port is an opening on computer network equipment that Ethernet cables plug into. Ethernet ports accept cables with RJ-45 connectors.

This tutorial examines the basic technical elements of Ethernet including Ethernet frames, transmission protocol, devices, and cables.

Gigabit Ethernet is an extension to the family of Ethernet computer networking and communication standards supporting a theoretical maximum data rate of 1000 Mbps (1 Gbps).

Basic Ethernet switches can be used on home networks to connect computers. Most home network routers contain built-in Ethernet switches, but for those people who don't have or want routers, a network switch can also be purchased separately.

Wake on LAN (WoL) is an Ethernet network technology that allows you to power on a computer remotely. Wake on LAN was originally designed for use by professional administrators of local area networks (LANs), but it can be set up to work with any modern PC.

Power over Ethernet technology enables ordinary Ethernet network cables to function as power cords. Power over Ethernet was designed for use with portable and wireless electronic equipment like Wi-Fi access points (APs).

This interactive test presents questions and answers on the essentials of Ethernet technology.

Autosensing is a feature of 10/100 Ethernet hubs, switches, and NICs. Autosensing was developed to make the migration from traditional Ethernet to Fast Ethernet products easier.

This article discusses the inner workings of Ethernet including CSMA/CD, segmentation, IEEE 802.3 and alternative standards.

Learn about the protocols behind half-duplex and full-duplex Ethernet communications.

See the format and contents of Ethernet frames including various technical extensions like jumbo frames.

An Ethernet cable is a popular type of network cable used for high-speed networking between two devices. Ethernet cables typically connect computers, routers and switches on IP networks.

Compare and contrast the OSI physical layer specifications for all major Ethernet flavors including 10Base-T, 100Base-TX and 1000Base-T.
