Thick Ethernet was the first commercially available form of cabling supported by Ethernet. It is technically known as 10-BASE-5. Here, 10 is the maximum throughput, i.e. 10 Mbps, BASE denoted use of baseband transmission, and 5 refers to the maximum segment length of 500 metres (1, 600 ft). This type of cabling allows 100 stations to be connected to it by vampire taps. The stations share a single collision domain.Structure of CableThe coaxial cable of thick Ethernet is 0.5 inches in diameter and usually has a yellow outer PVC coating. It is a low-loss 50 Ohm cable and is somewhat ... Read More

DIX standard is a popular standard for Ethernet that was put forth in 1978. The name DIX is an abbreviation of the three organizations who implemented it, namely DEC, Intel and Xerox. DIX Ethernet provides data speed of 10 Mbps.DIX Ethernet is also known as Ethernet II framing. The main fields of a frame of DIX Ethernet are −Preamble: It is an 8 bytes starting field that provides alert and timing pulse for transmission.Destination Address: It is a 6 byte field containing physical address of destination stations.Source Address: It is a 6 byte field containing the physical address of the sending ...

Ethernet is a set of technologies and protocols that are used primarily in LANs. It was first standardized in 1980s as IEEE 802.3 standard.Ethernet can be broadly classified into two types −What are classic Ethernet and switched Ethernet?Classic Ethernet is the original form of Ethernet that provides data rates between 3 to 10 Mbps. The stations are connected by hubs that allow each station to communicate with every other station in the LAN. There are a number of varieties of classic Ethernet, commonly referred as 10BASE-X. Here, 10 is the maximum throughput, i.e. 10 Mbps, BASE denotes use of baseband ... Read More

It comprises of an Ethernet medium composed of a long piece of coaxial ... Read More

Ethernet is a set of technologies and protocols that are used primarily in LANs. It was first standardized in 1980s as IEEE 802.3 standard. Ethernet is classified into two categories: classic Ethernet and switched Ethernet.In switched Ethernet, the hub connecting the stations of the classic Ethernet is replaced by a switch. The switch connects the high-speed backplane bus to all the stations in the LAN. The switch-box contains a number of ports, typically within the range of 4 – 48. A station can be connected in the network by simply plugging a connector to any of the ports. Connections from ... Read More

Ethernet is a set of technologies and protocols that are used primarily in LANs. It was first standardized in 1980s by IEEE 802.3 standard. IEEE 802.3 defines the physical layer and the medium access control (MAC) sub-layer of the data link layer for wired Ethernet networks. Ethernet is classified into two categories: classic Ethernet and switched Ethernet.Classic Ethernet is the original form of Ethernet that provides data rates between 3 to 10 Mbps.

IEEE 802.3 is a set of standards and protocols that define Ethernet-based networks. Ethernet technologies are primarily used in LANs, though they can also be used in MANs and even WANs. IEEE 802.3 defines the physical layer and the medium access control (MAC) sub-layer of the data link layer for wired Ethernet networks.IEEE 802.3 Popular VersionsThere are a number of versions of IEEE 802.3 protocol. The most popular ones are.IEEE 802.3: This was the original standard given for 10BASE-5. It used a thick single coaxial cable into which a connection can be tapped by drilling into the cable to the ... Read More

Clear to Send (CTS) is a control frame employed in the medium access control (MAC) layer protocol IEEE 802.11 RTS/CTS. The protocol uses the concept of Multiple Access with Collision Avoidance (MACA) in wireless networks. The RTS/CTS (Request to Send / Clear to Send) mechanism aims to reduce frame collisions introduced by the hidden terminal problem. CTS frame is sent by the receiver after it gets the RTS frame prior to receiving of the actual data frame.Working Principle of MACA implementing CTSThe MACA protocol works with the condition that the communicating stations are synchronized and frame sizes and data speed ...
