NETWORK architecture
definition: The design of computers, devices
and
media in a network.
1) Peer-to-peer network
•A simple, inexpensive network that typically connects fewer than 10
computers.
•Each computer, called
a peer,
has equal responsibilities and capabilities.
•Sharing hardware (such as a printer),
data or information with
other computers on
the peer-to
peer network.
peer network.
•Each computer stores files on its own storage devices. Thus, each computer
on the network
contains both the server operating system and application software.
contains both the server operating system and application software.
•All computers on the network share any peripheral device(s) attached to any computer.
•Peer-to-peer networks are ideal for very small businesses and home users.
•Some operating systems, such as Windows, include a peer to-peer networking utility that
allows users to set up a peer-to-peer network.
•Peers are both suppliers and consumers of resources.
•Each node is a computer on the network which acts and communicates with other Peers to
make a portion of their resources, such as processing power, disk storage or network
bandwidth.
•Directly available to other network participants, without the need for central coordination by
servers or stable hosts.
•One or more computers act as a server,
and the other computers on the network request
services from the server.
•Server, sometimes called a host computer, controls access to the hardware, software, and
other resources on the network and provides a centralized storage area for programs, data and
information.

2)Client/server network
services from the server.
•Server, sometimes called a host computer, controls access to the hardware, software, and
other resources on the network and provides a centralized storage area for programs, data and
information.
•The clients are other computers and mobile devices on the network that rely on the server for
its resources.
its resources.
•For example, a server might store a database of customers. Clients on
the network (company
employees) access the customer database
on the server.
•Client/server
architecture works when the client
computer sends a resource or process
request to the server over the network connection, which is then processed and delivered to the
client.

client.
•A server can manage several clients
simultaneously,
whereas one client can be connected to
several servers at a time, each providing a different set of services.

•The Internet is also based on client/server architecture where the Web
server serves many
simultaneous users with Web page and or website data.
