- Quote: "Ethernet is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN)."
A wired network standard that uses copper and fiber optic cables to enable high speed communication between devices.
Ethernet Basics: This includes the history and evolution of Ethernet, its advantages and limitations, and the various standards and modes of Ethernet operation.
Ethernet Cables: Ethernet cables carry data from one device to another in a network. These cables can be categorized by their type, such as Cat5, Cat6, or Cat7, and their length limitations should be taken into account during installation.
Ethernet Switches: Ethernet switches are devices used to connect multiple Ethernet devices to the same network. Understanding their types, functions, and configuration options are essential for network design.
Ethernet Frames: Ethernet frames are packets of information sent across a network. They contain various components, including a header, data, and a checksum.
Ethernet Protocols: Different Ethernet protocols are used for different purposes, such as transmitting data or controlling network traffic. Understanding these protocols is important for maintaining a reliable and secure network.
Ethernet Topology: Ethernet topology determines how devices are interconnected on a network. Different types of topologies include bus, ring, and star.
Ethernet Speeds: Ethernet speeds refer to the rate at which data can be transmitted across a network. Different speeds are available depending on the network’s components and protocols being used.
Ethernet Transmission: Ethernet transmission involves the transfer of data from one device to another in a network. Understanding the different modes of transmission, like half-duplex and full-duplex, is crucial for effective network design.
Ethernet Security: Securing Ethernet networks involves implementing appropriate authentication, encryption, and access control measures. This includes configuring firewalls, VPNs, and other security protocols.
Ethernet Troubleshooting: Troubleshooting Ethernet networks involves identifying and resolving issues that arise during network operation. This requires an understanding of network components and protocols and their functionalities.
10BASE-T: This is an Ethernet standard that operates at 10 Mbps over twisted-pair copper wires. It was one of the earliest Ethernet standards and has largely been replaced by faster ones.
100BASE-T: This Ethernet standard operates at 100 Mbps over twisted-pair copper wires. It is still widely used in many networks today.
Gigabit Ethernet: This Ethernet standard operates at 1 Gbps speeds over twisted-pair copper wires, optical fiber cables or even wireless transmission. It is commonly used in modern networks for high-speed data transfer.
10 Gigabit Ethernet: This Ethernet standard operates at 10 Gbps speeds over optical fiber cables or copper wires. It is often used in data centers and other high-performance computing environments.
40 Gigabit Ethernet: This Ethernet standard operates at 40 Gbps speeds over optical fiber cables.
100 Gigabit Ethernet: This Ethernet standard operates at 100 Gbps speeds over optical fiber cables.
400 Gigabit Ethernet: This Ethernet standard operates at 400 Gbps speeds over optical fiber cables.
Power over Ethernet (PoE): This is a technology that allows network devices to receive power and data over the same Ethernet cable. It is commonly used to power IP phones, wireless access points, and network cameras.
Ethernet over Power (EoP): This is a technology that uses a building's electrical wiring to transmit Ethernet signals. It is often used in situations where it is difficult or impractical to run Ethernet cables.
Ethernet over Coax (EoC): This is a technology that uses coaxial cables to transmit Ethernet signals. It is often used in legacy networks where coaxial cables are already in place.

- Quote: "Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances."
- Quote: "Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI, and ARCNET."
- Quote: "The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium."
- Quote: "This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both cheaper and easier to use."
- Quote: "More modern Ethernet variants use twisted pair and fiber optic links in conjunction with switches."
- Quote: "Ethernet data transfer rates have been increased from the original 2.94 Mbit/s to the latest 400 Gbit/s, with rates up to 1.6 Tbit/s under development."
- Quote: "Per the OSI model, Ethernet provides services up to and including the data link layer."
- Quote: "Systems communicating over Ethernet divide a stream of data into shorter pieces called frames."
- Quote: "Each frame contains source and destination addresses and error-checking data."
- Quote: "Most often, higher-layer protocols trigger retransmission of lost frames."
- Quote: "The 48-bit MAC address was adopted by other IEEE 802 networking standards, including IEEE 802.11 (Wi-Fi), as well as by FDDI."
- Quote: "Ethernet is widely used in homes and industry and interworks well with wireless Wi-Fi technologies."
- Quote: "The Internet Protocol is commonly carried over Ethernet."
