Repeaters are network devices operating at physical layer of the OSI model that amplify or regenerate an incoming signal before retransmitting it. They are incorporated in networks to expand its coverage area. They are also known as signal boosters.Why are Repeaters needed?When an electrical signal is transmitted via a channel, it gets attenuated depending upon the nature of the channel or the technology. This poses a limitation upon the length of the LAN or coverage area of cellular networks. This problem is alleviated by installing repeaters at certain intervals.Repeaters amplifies the attenuated signal and then retransmits it. Digital repeaters can ... Read More

Thick EthernetThick 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.Thin EthernetThin Ethernet, popularly known as cheapernet or thinnet, is among the family of Ethernet standards that uses thinner coaxial cable as a transmission media. It is technically known as 10-BASE-2.Here, 10 is the maximum throughput, i.e. ... Read More

Thin Ethernet, popularly known as cheapernet or thinnet, is among the family of Ethernet standards that uses thinner coaxial cable as a transmission media. It is technically known as 10-BASE-2. Here, 10 is the maximum throughput, i.e. 10 Mbps, BASE denoted use of baseband transmission, and 2 refers to the maximum segment length of about 200 metres (precisely 185 metres).This type of cabling allows a maximum of 30 stations to be connected to it by BNC connectors with 50 centimetres minimum gap between subsequent stations.Features of Cable and NetworkThe salient features of 10-BASE-2 Ethernet cabling are −10-BASE-2 use RG-58 A/U ...

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

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
