LOCAL AREA NETWORK ARCHITECTURE

Client Server Architecture

The client –server model of computing is a distibuted

application structure that partitions tasks or workloads

between the providers of a resource or service,called

servers,and service requesters,called clients.O ften

clients and servers communicate over a computer

network on separate hardware,but both client and server

may reside in the same system.A server host runs one or

more server programs which share their resources with

clients.A client does not share any of its resources ,but

requests a server’s content or service function.clients

therefore initiate communication sessions with servers

which await incoming requests..

BackUp Procedure

• Online data backup can be used for backing up datas.

• Data storage sever (data backup server) can be used as

equipment.

• Data backup systems

Definition

In storage technology online backup means to backup data

from own hard drive to a remote data backup server or

computer via a network connection.Backup’s are useful

primarily for two purposes ..

-The first is to restore a state following a disaster

(called disaster recovery)

-The second is to restore small numbers of files

after they have been accidently deleted or corrupted
