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)
name 3
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
