Q

what is a Switch?

A

a switch is a mechanism we use to connect networked devices such as clients and servers using a switch port.

17
Q

how does Switch work?

A

switches works by learning and identifying what devices are on which switch port and only forward traffic it receives from a port to the destination port based on that particular device MAC address.

18
Q

why are switches relevant today?

A

switches are relevant today because they provide more security and efficiently uses available bandwidth

19
Q

what is a router?

A

a router is a mechanism that connects two different network together.

20
Q

how does Routers work?

A

Routers work by intelligently forwarding traffic to and from a network based on its logical address.

21
Q

how does Routers determine routing of traffic?

A

Routers are able to forward traffic to logical addresses using IP (Internet protocol) address to determine routing of traffic.

22
Q

What is Media?

A

a media is a mechanism that connects two devices or a device to a port.

23
Q

what are the 3 types of cables media ?

A

media are made from

a) copper cable
b) fiber optics cables
c) radio frequency waves (WIFI)

24
Q

why is it important to learn about the types of media cables ?

A

it is important to learn about the different types of cables a media can be made from because each types has their strength and limitations, such as it available bandwidth, capacity, distance that can be covered, and cost to install and maintain.
