Question No: 21 ( Marks: 5 )
Differentiate between the Ring Topology and Star Topology.
Answer:
Topology: Topology can be defined as the physical arrangement of devices
in a network. There are three types of topologies namely BUS topology,
Star topology and Ring topology.
Differences between Ring and Star Topology:
Ring Topology Star Topology
1. Each device in this topology is
connected to two devices at a time in
form of a ring.
2. Data travels from device to device to
reach the destination.
3. Data can travel in one direction only
either clockwise or counter clockwise.
1. All the devices are connected at a
central point of connection through a
device called HUB.
2. Data first goes to the HUB which
then by checking the receiver address
send data to destination.
3. No set direction as data directly goes
to HUB.
Question No: 22 ( Marks: 10 )
a) Why we use router instead of switch on WAN?(5)
Answer: Router and switch use a hardware and software combination to
send data over a network. Routers divide the larger networks like WAN
(Wide Area network) into smaller segments called subnets. Router uses
Routing information protocol and make up a routing table which contains
information about network addresses and routes to deliver data. Unlike
switch which uses MAC address, router uses IP address of the destination
attached to the data packet and finds the shortest possible path available
to send the data to the destination in this way router are more efficient in
sending data over larger networks like WAN.
b) Differentiate between the Switch and Router? Any three differences.(5)
Answer:
Differences between Switch and Router:
Switch and router are networking devices which are used in a network to
send data. Both switch and router use a combination of hardware and
software to send data.
Switch Router
1. In switch the network is divided into
smaller segments known as Virtual
LAN.
2. It uses MAC address check to send
the data to the destination.
3. It is not a decision making device.
1. The larger networks are further
divided into smaller parts known as
Subnets.
2. It uses IP address to check the
shortest available path to reach the
destination device.
3. Router is a decision making device.
