CATEGORIES OF ETHERNET

DIFFERENT TYPES OF ETHERNET:

Depending on the encoding and decoding operation Ethernet are categorized into four:

STANDARD ETHERNET:

Standard Ethernet is implemented using digital signaling with the data rates of 10 Mbps.  Whereas at the sender, the data is converted into a digital signal using Manchester scheme. While at the receiver it uses Manchester scheme in order to decode the received signal. Manchester scheme is self-synchronous used for providing a transition at each bit interval. Standard Ethernet are categorized in to four types. They are as shown in below figure.

10BASE5 🙁 THICK ETHERNET)

This is the first implementation of standard Ethernet it is also known as thick ethernet. Name is derived based on the size of the cable. It is the first implementation which used bus topology with an external transceiver connected via a tap to a thick coaxial cable. Where transceiver is used for transmitting and receiving and detecting collisions. In order to provide separate path for transmitting and receiving data via transceiver cable. The maximum length of the cable should not exceed 500m, otherwise there will be degradation of the signal.

                 Transceiver          Thick coaxial cable maximum 500 m

10BASE 2: (THIN ETHERNET)

Thin ethernet is the second implementation of standard ethernet it also uses the bus topology, but the cable very thinner and more flexible. In this, the transceiver is the part of the network interface card (NIC), which is installed inside the station. It is very less expensive when compared with the thick ethernet, Its installation is simpler because of flexible. And the length of the thin ethernet is 185m.

10BASE-T: (TWISTED PAIR)

Twisted pair ethernet is the third implementation of the standard ethernet, which uses star topology. In which stations are connected to a hub via two pair of twisted cable. In this two pair of twisted cable create two paths between the station and hub. The maximum length of the cable is 100m.

10BASE-F: (FIBER CABLE)

10BASE-F uses a star topology to connect stations to a hub, the stations are connected to the hub using two fiber-optics cables.
