What protocol is used by DNS name servers ?
DNS uses UDP for communication between servers. It is a better choice than TCP because of the improved speed a connectionless protocol offers. Of course, transmission... Read more »

Which are the three types of routing tables ?
The three types of routing tables are fixed, dynamic, and fixed central. The fixed table must be manually modified every time there is a change. A dynamic table... Read more »
What is source-route bridging algorithm ?
The source-route bridging (SRB) algorithm was developed by IBM and was proposed to the IEEE 802.5 committee as the means to bridge between all LANs. SRBs are so... Read more »
What is Transparent Bridge ?
Transparent bridges were first developed at Digital Equipment Corporation (Digital) in the early 1980s. Transparent bridges are so named because their presence and... Read more »
What is the basic difference between transparent bridges and source-route bridges relative to the forwarding processes ?
In a transparent bridged environment, bridges determine whether a frame needs to be forwarded, and through what path based upon local bridge tables. In an SRB network,... Read more »

What is Enhanced Interior Gateway Routing Protocol ?
The Enhanced Interior Gateway Routing Protocol (EIGRP) represents an evolution from its predecessor IGRP. This evolution resulted from changes in networking and... Read more »
Name the four key technologies that are used by EIGRP ?
EIGRP employs four key technologies, including neighbor discover/recovery, Reliable Transport Protocol (RTP), Diffusing Update ALgorithm (DUAL) finite-state machine,... Read more »
Why EIGRP is more efficient in operation than IGRP ?
Unlike most other distance vector routing protocols, EIGRP does not mandate a periodic update of routing tables between neighboring routers. Instead, it employs... Read more »
What is Interior Gateway Protocol ?
IGRP is a distance vector Interior Gateway Protocol (IGP). Distance vector routing protocols mathematically compare routes using some measurement of distance. This... Read more »
What is RIP (Routing Information Protocol)?
The Routing Information Protocol, or RIP, as it is more commonly called, is one of the most enduring of all routing protocols. RIP sends routing-update messages... Read more »
What is SLIP (Serial Line Internet Protocol)?
The Serial Line Internet Protocol (SLIP) is a mostly obsolete encapsulation of the Internet Protocol designed to work over serial ports and modem connections. It... Read more »
What is a Multi-homed Host?
A computer that is connected to more than one physical data link, these data links may or may not be attached to the same network. The host may send and receive... Read more »
What is Gateway-to-Gateway protocol?
GGP is a “min-hop” algorithm, i.e., its length measure is simply the number of network hops between gateway pairs. It implements a distributed shortest-path... Read more »
What is the minimum and maximum length of the header in the TCP segment and IP datagram?
