types of network architecture
a network in which each computers have equal capabilities and responsibilities to share hardware,data and information with others computer on the network
suitable for small network where high level security is not necessary
Each computer stores files on its own storage
More reliable because failure of one peer will
not affect other peers.
All the peers can share their resources to
Easy and inexpensive to set up the network.
Data recovery or backup is very difficult. Each
computer have to maintain its own backup
Lack of security control or other management
A network in which one or more computers act as
a server, and the other computers, called client,
request services from the server.
A server, or host, is a computer that controls access to
hardware, software and other resources on the
network and provides a centralized storage for
programs, data and information.
Clients are other computers or devices on the network
that rely on the server for its resources.
Efficient for large network which handle sensitive
and confidential data.
Require a network administrator to manage the
Examples of client/server systems are:
automated teller machine (ATM) network
email service (ex: gmail)
World Wide Web (www)
Centralized control by the server promotes
better security and management of the
Data backup and recovery is easier since all
data is stored in the server
Less reliable because too dependent on the
server; failure of server will affect the
Network congestion may occur if too many
clients request services from server at the
High cost to set up and maintain the network.
refers to the design of computers, devices and media on the network
