Networks - Topologies 1.3

Question 1

topology

Answer 1

-way which parts of a system are connected

Question 2

star topology - pros

Answer 2

-fast data transfer as wires aren’t shared
-high performing = no data collisions
-reliable = if 1 cable stops working - others aren’t affected

Question 3

star topolgy

Answer 3

In a star network each device on the network has its own cable that connects to a switch

Question 4

star topology cons

Answer 4

-expensive = lots of hardware cables
-if switch fails = network can’t work

Question 5

Bus topology

Answer 5

all the workstations, servers and printers are joined to one cable

Question 6

what are at the end of all bus topologies

Answer 6

a terminator is fitted to stop signals reflecting back down the bus.

Question 7

Bus topology pros

Answer 7

-easy to install
-cheap to install = little cable required

Question 8

bus topology cons

Answer 8

-if the main cable fails the whole network will fail
- slower as more devices are connected because of data collisions
- every workstation on the network “sees” all of the data on the network – this is a security risk
