1 Define frame relay. Describe itsformat with diagram.
Answer: Frame relay is a packet-switching technology that provides dynamic bandwidth assignments.
Frame relay systems are a simple bearer (transport only) technology and do not offer advanced error
protection or retransmission. Frame relay were developed in the 1980s as a result of improved digital
network transmission quality that reduced the need for error protection. Frame relay systems offer
dynamicdata transmissionratesthroughthe use of varyingframe sizes.

2 Define portsand explainthe two types of ports.
Answer: An interface on a computer to which you can connect a device. Personal computers have
various types of ports. Internally, there are several ports for connecting disk drives, display screens, and
keyboards. Externally, personal computers have ports for connecting modems, printers, mice, and other
peripheral devices.

3Write note on:
(a)The Hierarchical Namespace
Answer: The DNS hierarchical namespace is a map of how DNS servers determine what IP address to
connectto givena URL.
Registrars: Registrars, such as VeriSign, the operator of the .com and .net top-level domains, let any
company, organization, or private individual register a TLD for any number of years. The domain name is
then added to the Whois directory, and may point to a specific DNS server, which translates the domain
name intoan IP address.
Map: Domainnamesare readfrom right
(b) FullyQualifiedDomain Names(FQDNs)
Answer: A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or
host, on the Internet. The FQDN consists of two parts: the hostname and the domain name. For
example, an FQDN for a hypothetical mail server might be mymail.somecollege.edu. The hostname is
mymail,andthe hostis locatedwithinthe domainsomecollege.edu.
In this example, .edu is the top-level domain (TLD). This is similar to the root directory on a typical
workstation, where all other directories (or folders) originate. (Within the .edu TLD, Indiana University

4 Define Telnetandexplainits operation.
Answer: Telnet is an application protocol used on the Internet or local area networks to provide a
bidirectional interactive text-oriented communication facility using a virtual terminal connection. User
data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection
overthe TransmissionControl Protocol (TCP).

5 Define and explain Internet Message Access Protocol (IMAP4). Describe Fundamental IMAP4
ElectronicMail Models.
Answer: IMAP (Internet Message Access Protocol) is a standard protocol for accessing e-mail from your
local server. IMAP (the latest version is IMAP Version 4) is a client/server protocol in which e-mail is
received and held for you by your Internet server. You (or your e-mail client) can view just the heading
and the sender of the letter and then decide whether to download the mail. You can also create and
manipulate multiple folders or mailboxes on the server, delete messages, or search for certain parts or
an entire note.IMAPrequirescontinual access

3. 6 Give an overviewofHTTP operation.
Answer: The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative,
hypermedia information systems. HTTP is the foundation of data communication for the World Wide
Web.
Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP is
the protocol to exchange ortransferhypertext.
The standards development of HTTP was coordinated by the Internet Engineering Task Force (IETF) and
the World Wide Web Consortium (W3C), culminating in the publication of a series of Requests for
Comments (RFCs), most notably RFC 2616 (June 1999), which defined HTTP/1.1, the version of HTTP
most commonly used today. In June 2014, RFC 2616 was retired and HTTP/1.1 was redefined by RFCs
7230, 7231, 7232, 7233, 7234, and7235.[2] HTTP/2 iscurrentlyindraft form.
