someone at your own level
he "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server.

Q.8.
Peer-to-Peer (P2P) Networks
he "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server.
a powerful computer which provides services required by any of the clients (computers on the network)
the computers which people log on to in order to use the network
A computer network in which one centralized, powerful computer is the middle where many less powerful personal computers (called clients) are connected. The clients run programs and access data that are stored on the server
Q.9.
Server
a powerful computer which provides services required by any of the clients (computers on the network)
the computers which people log on to in order to use the network
A computer network in which one centralized, powerful computer is the middle where many less powerful personal computers (called clients) are connected. The clients run programs and access data that are stored on the server
figuring out the secret code by clever guessing, maybe by trying to find patterns in the data, by using knowledge of the data.
Q.10.
Client
the computers which people log on to in order to use the network
