A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
A network's logical topology is not necessarily the same as its physical topology. For example, the original twisted pair Ethernet using repeater hubs was a logical bus topology carried on a physical star topology. Token Ring is a logical ring topology, but is wired as a physical star from the media access unit.
Wired communication refers to the transmission of data over a wire-based communication technology (telecommunication cables). Wired communication is also known as wireline communication . Examples include telephone networks , cable television or internet access , and fiber-optic communication .
Jabbering ports are partitioned off the network until a carrier is no longer detected. [63] End nodes utilizing a MAC layer will usually detect an oversized Ethernet frame and cease receiving. A bridge/switch will not forward the frame. [64] A non-uniform frame size configuration in the network using jumbo frames may be detected as jabber by ...
Wire protocols provide the means for a program running under one operating system to communicate with a program running under some other operating system over a network such as an organization's intranet or the Internet. The protocol thus interconnects multiple platforms.
An ATM network interface in the form of an accessory card. A lot of network interfaces are built-in. A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an ...
OSI was an industry effort, attempting to get industry participants to agree on common network standards to provide multi-vendor interoperability. [17] It was common for large networks to support multiple network protocol suites, with many devices unable to interoperate with other devices because of a lack of common protocols.
