Q

How does Bus Topology work?

A

Bus topology works by tapping into the cable that is running through the area using either a T connector or a Vampire Tap.

Q

why is Bus topology not popular today

A

it is not popular today because all the devices that is tapping into the Network forms a single collision domain.

Q

How does Ring Topology work?

A

Ring topology works by connecting each device to a ring, this allows that data to travel in a singular direction.

Q

what is the difference between FDDI Rings and Token Rings?

A

FDDI Rings works by using two counter rotating rings for redundancy while Token rings wait for a turn to communicate on a ring by passing a token.

16
Q

where do we usually find STAR topology in a network

A

we find it being used in Ethernet cabling, wireless and fiber as well.

17
Q

Why is Star topology not common today?

A

it is not common used today because of it high risk of failure. for example if the central device where all he cable to connecting to that single point fails, the entire network fails.

18
Q

what is a Hub and Spoke Topology (wired)?

A

Hub and Spoke Topology works by connecting multiple sites using different cabling connections and various central hubs connectivity.

19
Q

is Hub and Spoke Topology redundant?

A

No. if central (hub ) fails, the whole network can fails.

20
Q

what is a full Mesh Topology (wired)?

A

Full Mesh works by connecting each node in a cable to every other node, this makes for optimal routing .

21
Q

what is the downside of full Mesh Topology?

A

very expensive to maintain and operate

22
Q

is full Mesh Topology redundant?

A

yes. it has the most redundancy.

23
Q

what is a Partial Mesh Topology (wired)?

A

a consortium of full-mesh and hub and spoke typologies which work together to provide optimal routes between some sites, while avoiding the expense of connecting to every site.

24
Q

how does Partial Mesh Topology work?

A

it works by considering the network traffic patterns to effectively provide optimal routes.

25
Q

List the 2 types of wireless Network Topology

A

1) Infrastructure mode
2) Ad hoc Mode
3) Wireless Mesh topology

26
Q

what is a Infrastructure mode (wireless)?

A

a common type of wireless network that works by requiring centralized management.

27
Q

How does Infrastructure mode (wireless) work?

A

it works by using a wireless access point as a centralized point like a star topology and supports wireless security controls.

28
Q

what is an Ad hoc Mode (wireless)?

A

Ad hoc Mode is a type of decentralized wireless network which works by operating without routers or central access point.

29
Q

How does Ad hoc Mode (wireless) work?

A

it works by allowing forwarding decision for data on the network to be dynamic and allows creation and joining of network on the fly. also it creates pc to pc connections.

30
Q

what is a Wireless Mesh topology (wireless)?

A

a type of wireless network which consists of clients, routers and gateways.

31
Q

How does Wireless Mesh topology (wireless) work?

A

it works by interconnecting different types of nodes or devices. it uses radio frequencies to extend and expand access.

32
Q

is Wireless Mesh topology redundant?

A

yes. it a very reliable and redundant.
