Answer.
1.
Node: Any
device, including routers and hosts, that runs an implementation of IP.
2.
Route: A node
that can forward IP packets not explicitly addressed to itself. On an IPv6
network, a router also typically advertises its presence and host configuration
information.
3.
Host
Q2.
What do you mean by frame relay? Describe the frame relay frame format with
diagram. 3+7
Answer.
Frame
relay
The frame relay network provides
a number of virtual circuits that form the basis for connections between
stations attached to the same frame relay network. The resulting set of
interconnected devices forms a private frame relay group, which can be either
fully interconnected with a complete mesh of virtual circuits, or only
Q3.
Define ports and explain the two types of ports. 2+4+4
Answer.
Ports
Each process that wants to
communicate with another process identifies itself to the TCP/IP protocol suite
by one or more ports. A port is a 16-bit number used by the host-to-host
protocol to identify to which higher-level protocol or application program
(process) it must deliver incoming messages.
Types
of ports
Q4.
Describe the following operations of FTP:
1.
Connect to a remote host
2.
Navigate and manipulate the directory structure.
3.
List files available for transfer.
Answer.
1.
Connect to a remote host
To execute a file transfer, the
user begins by logging in to the remote host. This is only the primary method
of implementing security within the FTP model. Additional security can be
provided using SSL and TLS. Conversely, this authentication can be bypassed
using anonymous FTP . There are four commands that are used:
Open: Selects the remote host and
initiates the login session.
Q5.
Define and explain Internet Message Access Protocol (IMAP4). Describe
Fundamental IMAP4 Electronic Mail Models. 4+6
Answer.
Internet
Message Access Protocol
The Internet Message Access
Protocol, Version 4 is an electronic messaging protocol with both client and
server functions. It is defined by RFC 3501. Similar to POP, IMAP4 servers
store messages for multiple users to be retrieved upon client requests, but the
IMAP4 model provides more functionality to users than does the POP
Q6.
Define web servers. List and explain all well-known web servers. 3+7
Answer.
Web
servers
Web servers are responsible for
servicing requests for information from Web browsers. The information can be a
file retrieved from the server's local disk, or it can be generated by a
program called by the server to perform a specific application function. There
are a number of public-domain Web servers available for a variety of platforms,
including most UNIX variants, as well as personal computer environments such as
Microsoft Windows. Some well-known public domain servers are CERN, NCSA httpd,
and Apache servers.
