Ethernet
Ethernet is usually IEEE 802.3 standard based physical interface from the router. The operating speed from the port is 10 Mbps. The press standard with this interface is 10BaseT.
Fast Ethernet
The Short Ethernet is also known may be the FE interface. It’s IEEE 802.3u standard based physical interface. The operating speed of Fast Ethernet is 100 Mbps. The press standard employed for Fast Ethernet interface is 100BaseT.
Gigabit Ethernet
Gigabit Ethernet is also referred to as GE interface. This ports standard is Ethernet IEEE 802.3ab. Gigabit Ethernet can connect in the outstanding speed of 1000mb/s. The press standard used is1000BASE-T
Serial interfaces
A serial interface is really a communication interface between two digital systems that transmit data as a number of current pulses lower a wire. Serial interfaces typically employed for WAN connections from ISP for hosting. the serial interface provides connectivity types like Frame Relay, T1, T3, etc
FDDI
Fiber Distributed Data Interface is some ANSI and ISO standards for data transmission on fibre optic lines inside a lan (LAN). The plethora of FDDI can extend in range as much as 200 km. FDDI systems operate at 100 Mbps speed and employ an expression-passing mechanism to avoid collisions.
Token Ring
An expression ring network is really a lan (LAN) by which all computers connected inside a ring or star topology and pass a number of logical tokens from location of host. Merely a host that holds an expression can send data, and tokens released when delivery of the data confirmed. Token Ring interfaces can operate at either 4 Mbps or 16 Mbps. Token Ring systems missing from networking industry lengthy long ago. New ‘cisco’ routers don’t have an expression Ring interface.
Loopback interface
A loopback interface is really a logical, virtual interface inside a ‘cisco’ Router. This isn’t an actual interface like Fast Ethernet interface or Gigabit Ethernet interface. A loopback interface has important uses, for instance, being an OSPF Router ID.
Null Interface
A null interface is really a virtual interface that discards IP packets. It’s to avoid routing loops from occurring within the network. We don’t assign the Ip to some null interface.
