DATA COMMUNICATION SYSTEM
6. Understand computer network basics.(chapter 6)
6.6. Describe client / server and peer-to-peer network.
•A server is a computer that provides data to other computers. In client/server computing,
a server takes
requests from client computers and shares its resources,
applications and/or data with one or more client computers
on the network, and a client is
a computing device that initiates contact with a server in
order to make use of a shareable resource.

- File server A computer that stores and manages files for multiple users on a network
- Web server A computer dedicated to responding to requests (from the browser client) for web pages
Peer-to-Peer network
Stands
for
"Peer to Peer."
In a P2P
network, the
"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. In other words, each computer on a P2P
network becomes
a file server as well as a client.
