nodes(sender and receiver) through lines of connection.

A

Network Topology

25
Q

a network type in which every computer and network device is connected to
single cable. When it has exactly two endpoints.

A

Bus topology

26
Q

it forms a ring as each computer is connected to another computer, with the
last one connected to the first. Exactly two neighbors for each device

A

Ring Topology

27
Q

In this type of topology all the computers are connected to a single hub
through a cable. This hub is the central node and all point-to-point nodes are connected to the
central node.

A

Star Topology

28
Q
  • It is a point-to-point connection to other nodes or devices. All the network
    nodes are connected to each other.
A

Mesh Topology

29
Q

It has a root node, and all other nodes are connected to it forming a
hierarchy. It is also called hierarchical topology It should at least have three levels to the hierarchy

A

Tree Topology

30
Q

It is two different types of topologies which is a mixture of two or more
topologies For example, if in an office in one department ring topology is used and in another,
star topology is used

A

Hybrid Topology

31
Q

It is a hardware
component used to connect a computer with another computer
onto a network.

A

NIC (network interface card)

32
Q

– It is a hardware device that divides the network
connection among multiple devices.

A

Hub –

33
Q

When computer requests
for some information from a network, it first sends the request
to the Hub through ____. Hub will broadcast this request to _____. All the devices will check whether the request
belongs to them or not. If not, the request will be ____.

A

cable, the entire network, dropped

34
Q
  • It is a hardware device that connects multiple devices
    on a computer network. It contains more advanced features than Hub; contains the updated table that decides where the data is transmitted or not. It also delivers the message to the correct destination based on the physical address present in the incoming message.
A

Switch

35
Q
  • It is a hardware device which is used to connect a LAN
    with an internet connection. It is used to receive, analyze and
    forward the incoming packets to another network.
