Q

what is the simplest example of a

peer - to - peer (P2P) network

A

the simplest example of this would be:

two computers connected together, where both computers can send and receive resources from each other such as files.

16
Q

this is the amount of time it takes data to get from a source to a destination

A

what is

latency

17
Q

how is

bandwidth measured

A

this is typically measured in how many bits can be carried across said medium in 1 second

18
Q

some factors might include:

  1. Amount of data sent and received
  2. Types of data being sent
  3. Latencies created by network devices between source and destination
A

what

factors might affect throughput

19
Q

what is

throughput

A

this like bandwidth is a measure of bits across a medium over a given period of time, however throughput does not normally match bandwidth since it takes into account a number of factors

20
Q

some examples of this are:

  1. routers
  2. switches

these are concerned with transporting data fom a source to a destination and are any devices that lie between two end devices

A

name some examples of an

Intermediate device

27
Q

name some examples of an

end device

and the role they play

A

some examples of this are:

  1. smart phone
  2. laptop

these devices are concerned with data generation or data output

28
Q

name 3

common measurements of bandwidth or throughput

A

Common measurements include:

Thousands of bits per second (kbps)

Millions of bits per second (Mbps)

Billions of bits per second (Gbps)

29
Q

bandwidth can be thought of as a theoretical transfer speed of data for a device or media, whereas throughput can be thought of as the real world transfer speed of data.

A
