External Data Representation is a method of encoding data within an RPC message, used to ensure that the data is notsystem-dependent.

BOOTP helps a diskless workstation boot. How does it get a message to the network looking for its IP address and the location of its operating system boot files?

BOOTP sends a UDP message with a sub network broadcast address and waits for a reply from a server that gives it the IP address. The same message might contain the name of the machine that has the boot files on it. If the boot image location is not specified, the workstation sends another UDP message to query the server.

A resource record is an entry in a name server's database. There are several types of resource records, used including name-to-address and resolution information. Resource records are maintained as ASCII files.

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 reliability suffers with UDP.

Interior gateways connect LANs of one organization, whereas exterior gateways connect the organization to the outside world.

The HELLO protocol uses time instead of distance to determine optimal routing. It is an alternative to the Routing Information Protocol.

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 changes its information based on network traffic, reducing the amount of manual maintenance. A fixed central table lets a manager modify only one table, which is then read by other devices. The fixed central table reduces the need to update each machine's table, as with the fixed table. Usually a dynamic table causes the fewest problems for a network administrator, although the table's contents can change without the administrator being aware of the change.

It is the sequence of IP address to identify the route a datagram must follow source route may optionally be included in an IP datagram header.

It is a simple protocol used to exchange information between the routers.

It is a very simple protocol. It is used for the transmission of IP datagram's across a serial line.

It is an Internet routing protocol that scales well, can route traffic along multiple paths, and uses knowledge of an Internet's topology to make accurate routing decisions.

It is using a router to answer ARP requests. This will be done when the originating host believes that a destination is local, when in fact is lies beyond router.

It is an authentication service developed at the Massachusetts Institute of Technology. Kerberos uses encryption to prevent intruders from discovering passwords and gaining unauthorized access to files.

It is a host that has a multiple network interfaces and that requires multiple IP addresses is called as a Multi-homed Host.

It is a set of rules defining a very simple virtual terminal interaction. The NVT is used in the start of a Telnet session.

It is a protocol formerly used to exchange routing information between Internet core routers.

This is a protocol, which is used to advertise the set of networks. This can be reached within an autonomous system. BGP enables this information to be shared with the autonomous system. This is newer than EGP (Exterior Gateway Protocol).

It is a collection of routers under the control of a single administrative authority and that uses a common Interior Gateway Protocol.

It is the protocol routers in neighboring autonomous systems. It is used to identify the set of networks that can be reached within or via each autonomous system.

It is any routing protocol used within an autonomous system.

A system performs a protocol translation between different electronic mail delivery protocols.
