advantages of peer-to-peer (P2P) networks
- Easy to set up
- Less complex
- Lower cost due to no need of network devices or dedicated servers
- Can be used for tasks such as sending files or sharing a printer
- No central administration
- Not as secure
- Not scalable
- hosts acting as client and server can have their performance reduced

disadvantages of peer-to-peer (P2P) networks
this is a measure of how much data a medium such as copper wire or wireless transmission can (theoretically) carry
what is
bandwidth
what is
bandwidth
this is a measure of how much data a medium such as copper wire or wireless transmission can (theoretically) carry
what
factors might affect throughput
some factors might include:
- Amount of data sent and received
- Types of data being sent
- Latencies created by network devices between source and destination
name some examples of an
Intermediate device
and the role they play
some examples of this are:
- routers
- switches
these are concerned with transporting data fom a source to a destination and are any devices that lie between two end devices

disadvantages of peer-to-peer (P2P) networks
- No central administration
- Not as secure
- Not scalable
- hosts acting as client and server can have their performance reduced
this is a device that has software installed that enables it to request information from a server
what is a
client
on a network
these include:
- end device
- intermediate device
- network media
what are the 3
categories that hardware can be placed in
what is a
host
on a network
this is any device connected to a network
Common measurements include:
Thousands of bits per second (kbps)
Millions of bits per second (Mbps)
Billions of bits per second (Gbps)

common measurements of bandwidth or throughput
what is the simplest example of a
peer - to - peer (P2P) network
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.

advantages of peer-to-peer (P2P) networks
this is the amount of time it takes data to get from a source to a destination
what is
latency
how is
bandwidth measured
this is typically measured in how many bits can be carried across said medium in 1 second
some factors might include:
- Amount of data sent and received
- Types of data being sent
- Latencies created by network devices between source and destination
what
factors might affect throughput
what is
throughput
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
some examples of this are:
- routers
- switches
these are concerned with transporting data fom a source to a destination and are any devices that lie between two end devices
name some examples of an
Intermediate device
and the role they play
this is a device that has software installed that enables it to distribute information to other hosts on a network
what is a
server

these devices are concerned with data generation or data output

common measurements of bandwidth or throughput
Common measurements include:
Thousands of bits per second (kbps)
Millions of bits per second (Mbps)
Billions of bits per second (Gbps)
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.
how do
bandwidth and throughput differ

name some examples of an
end device
and the role they play
this can be described as a network that has hosts acting as both a client and a server
what is a
peer-to-peer (P2P) network
some examples are:
- copper cable
- optical fibre
this is the medium upon which data travels through to get from one device to the next
