Qus:1
Briefly explain OSI Reference Model.
Answer:
OSI
Reference Model:
An ISO standard
that covers all aspects of network communications is the OSI model, which was
first introduced in 1970s.
Open System: A set of protocols that allows any two
different systems to communicate regardless of their underlying architecture.
Qus:2
Briefly explain Integrated Services Digital Network and its services.
Answer:
Integrated
Services Digital Network and its services:
ISDN is
developed by ITU-T in 1976. It is a set of protocols that combines digital
telephony and data transport services. The whole idea is to digitize the
telephone network to permit the transmission of audio, video, and text over
existing telephone lines. ISDN is an effort to standardize subscriber services,
provide user/network interfaces, and facilitate the internetworking
capabilities of existing voice and data networks. The goal of ISDN is to form a
Qus:3
Briefly explain the IEEE 802 standards for LANs.
Answer:
The
IEEE 802 standards for LANs:
IEEE has standardized a
number of LAN’s and MAN’s under the name of IEEE 802. Few of the standards are
listed in figure 3.6. The most important of the survivor’s are 802.3 (Ethernet)
and 802.11 (wireless LAN). Both these two standards have different physical
layers and different MAC sub layers but
Qus:4
Briefly explain Point-to-Point Protocol.
Answer:
Point-to-Point
Protocol:
Point-to-Point
Protocol (PPP) is a network-specific standard protocol with STD number 51. Its
status is elective, and it is described in RFC 1661 and RFC 1662. The standards
defined in these RFCs were later extended to allow IPv6 over PPP, defined in
RFC 2472. There are a large number of proposed standard protocols, which
specify the operation of PPP over different kinds of point-to-point links.
Qus:5
Distinguish between IPV4 and IPV6 addressing schemes
Answer:
Distinguish
between IPV4 and IPV6 addressing schemes:
Qus:6
What is the role of Transmission Control Protocol in networking? Briefly
explain TCP Connection processes.
Answer:
The
role of Transmission Control Protocol in networking:
The main design
goal of TCP/IP is to build an interconnection of networks, referred to as an
internetwork, or internet, that provide universal communication services over
heterogeneous physical networks. The clear benefit of such an internetwork is
the enabling of communication
