what way is a peer-to-peer network different from client/server network?
- In peer-to-peer, tasks are allocated to only one member of the network while in a client/server network, a number of network clients or workstations request resources or services from the network.
- In peer-to-peer, tasks are allocated among all the members of the network while in a client/server network, a number of network clients or workstations request resources or services from the network.
- In peer-to-peer,a very powerful computer does all of the processing while in a client/server network, only one client requests resources or services from the network.
- In peer-to-peer, tasks are allocated among all the members of the network while in a client/server network, a very powerful computer does all of the processing.
- In peer-to-peer,a very powerful computer does all of the processing while in a client/server network, a number of network clients or workstations request resources or services from the network.
