LESSON 76
CLIENT / SERVER
CLIENT / SERVER NETWORK
On a client/server network, shared files and applications are stored in the server but network users can still store files on their individual PCs.
A smaller client/server network uses twisted-pair or coaxial cables for networking but a larger and powerful network will use fibre optics. A client/server network is suitable for connecting 10 or more computers.
SERVER
A server is sometimes called a host computer. A server is a computer that provides services to other computers called clients. A server controls access to the hardware, software and other resources on the network.
It provides a centralised storage area for programs, data and information.
DEDICATED SERVER
Dedicated servers perform specific tasks and usually execute only one job.
For example, a file server stores and manages files, a print server manages printers and print jobs. A database server stores and provides access to a database. A network server manages network traffic.
CLIENT
The client computers are computers on the network that rely on the server for its resources and services.
Client computers send requests to a server for resources or services to perform their job. For example, a client computer can send a request asking permission to use the printer attached to the server, to print a document. Usually a client computer has to log onto the network using a user name and password to use the server’s resources and services.
For example, you have to be a TMnet or Jaring member to use the internet service. You need to logon to TMnet or Jaring’s server by sending your username and password.
