3. List the three differences between TCP and UDP.
Answer:
TCP UDP
Tcp is the transmission protocol used for logging on, file and
print sharing, replication of info between domain controllers.
It is connection oriented.
UDP is mainly used for one to many connections
using broadcast or multicast IP datagrams. It is
connectionless
It is more reliable as it includes handshaking.
It is less reliable as it does not include handshaking.
It is one the main protocols for streaming.

4. Explain about different types of transmission media with appropriate diagram (Approximately 150
Words)
Answer:
There are basically two types of transmission media : guided and unguided. Guided media are the direct media in
which signals are transmitted directly. It has high speed , security and used for transmitting data for shorter
distance.
Guided media are of the following 3 types:
UTP : unsheilded transmission protocol - it is a cable that stops interference and is independent of physical media. It
is least expensive and high speed capacity.
STP : Shielded twisted pair - it consists of special jacket that helps in prevention of external interference . it is better
than UTP as in this transmission rate is high.
Coaxial cable - it is a cable having a pair of 2 parallel conductors and covered with plastic insulators. It has high
bandwidth and is easily installed in less cost.
Unguided madia : these are wireless and requires no physical media for transmission of data. It is also of 3 types:
Radiowaves - they penetrate through walls. They can be categorized as terrestrial and satellite
Microwaves - they use antennas for recieving and transmitting the data. Used for mobile communications.
Infrared - they are used for short distance communication, basically for printer, mouse, etc.

5. Discuss about MAC address. (Approximately 100 Words)
Answer:
Media Access Control Address
Network adapters on a ethernet network have unique media access control address
They are unique identifiers assigned to network adapters by the manufacturer of that particular device.
Mac address is six octets in length and written in hexadecimal.
E. g 00:02:db:38:9c:f1
F. First three octets are of the manufacturer and the last three are of the unique device.

7. Advantages and disadvantages of switches over hubs (Approximately 100 Words).
Answer:
Switches and Hubs both are central connecting devices, responsible for connecting hosts and transmitting data. But
they perform these functions in different ways.
HUB:
 Hosts sends data to a hub.
 The hub then broadcasts the data all to all other connected hosts on the network.
Suppose. We have 3 hosts connected by a hub and numbered 1,2,3 respectively.
So, if host 1 sends data to hub, the hub will send data to host 2 and host 3.
But what if host 1 only wants to send data to host 2?
we cannot do it with the help of hubs
Advantages:
 Can extend the total network distance.
 Can connect to network using different physical media
Disadvantages:
 Divides the total network bandwidth among each connected port.
 Cannot connect different network architectures
SWICH:
 Hosts sends data to a switch.
 Switches direct data to its intended destination.
 Unlike hubs, switches can send and receive data in simultaneously.
 Switches are the most common devices used to connect hosts to a network.
With the help of the switches we can transfer data from host 1 to only host 2
Advantages:
 increased available bandwidth.
 Increased network performance.
Disadvantages:
 more expensive.
 Problems can be difficult to trace.
8. What is VLAN? What is the purpose of using VLAN? (Approximately 100 Words)
Answer:
Vlan is the abstraction of local area network and it is called as virtual local area network. It uses the technique of
subnetting .

It divides the IP pool into various vlan and creating an image of abstraction.
It helps the network admins to partition a single switch to meet the requiremnents.
It aims to meet the functional and security requirements of the client.
Switches have ports that can be assigned to various vlans and can be allocated to the systems.
Each vlan provides data link access to the hosts or machines which are configured with same vlan ID.
Multiple vlans can be configured in single port using a trunk configuration.
9. Explain about Spanning Tree Protocol with examples. (Approximately 100 Words)
Answer:
The Spanning Tree Protocol (STP) is used to create loop-free topology among the switches in each Layer 2
domain. A per-VLAN STP instance can be used, which enables different Layer 2 topologies or a multi-instance
STP (MISTP) can be used to reduce STP overhead if the topology is the same among multiple VLANs. STP
blocks forwarding on links that might produce forwarding loops, creating a spanning tree from a selected root
switch. This blocking means that some links will not be used for forwarding until a failure in another part of
the network causes STP to make the link part of an active forwarding path.
10. Write a sample code for configuration of VLAN. (Approximately 100 Words)
Answer:
S1(config)#interface fastEthernet 0/1
S1(config-if)#switchport access vlan 10
S1(config-if)#interface fastEthernet 0/2
S1(config-if)#switchport access vlan 20
S1(config)#vlan 10
S1(config-vlan)#exit
S1(config)#vlan 20
S1(config-vlan)#exit
S1(config)#

Q11. What is a WLAN network? How does a wireless network operate? (Approximately 100 Words)
Answer:
Wireless local area network.
It is a distributed method for more than one devices that utilize radio waves of high frequency.
It also includes an access point to internet.
It allows the people or users to move in the vicinity without losing any network connection.
It is also called as local area wireless network.
Long ago, they were very expensive and were strategically used.
Every componenet of wlan is known as station and falls under either of the two categories : access point or client
Wlan overcomes the disadvantage of lan and hence used in many office campuses now.
