Pros & Cons

PEER-TO-PEER	CLIENT SERVER
(+)More independent	(-)Broken server , broken network
(+)File sharing	(-)Need a fast server
(+)No waiting time for server	(+)More security
(-)Low security	(+)Easier to configure many computers
(-)Slow sharing internet connection	-

Differences between client / server and peer-to-peer

CATEGORY	CLIENT / SERVER	PEER-TO PEER
SIZE	For medium & large network	For small network < 10 computers
OPERATING SYSTEM	Need a specific operating system such as windows server 2008	Does not need a specific operating system
TRAINING	Needs training	Does not need training
SET UP	More difficult to set up	Easy to set up
INSTALLATION	More expensive to install	Less expensive to install
IMPLEMENTATION	Big corporation or organization with high security data	Small businesses and home users

client / server network

A client-server network is a central computer, also known as a server, which hosts data and other forms of resources. Clients such as laptops and desktop computers contact the server and request to use data or share its other resources with it.

What Is a Client-Server Network?

A client-server network is designed for end-users, called clients, to access resources such as files, songs, video collections, or some other service from a central computer called a server. A server's sole purpose is to do what its name implies - serve its clients! You may have been using this configuration and not even have known it. Have you ever played Xbox Live or used the PlayStation Network? Your Xbox One is the client, and when it logs into the network, it contacts the Xbox Live servers to retrieve gaming resources like updates, video, and game demos.

How Does It Work?

Imagine a customer sitting at a restaurant. He is waiting for the server to come by and take his order. The same rules apply in a client-server network; the client, which can be a laptop, desktop, a smart phone, or pretty much any computerized device, can make a request from the server.

The client uses the network as a way to connect with and speak to the server. Just as the customer speaks to his server, the client uses the network to send and receive communications about its order, or request. The server will take the request and make sure that the request is valid. If everything checks out okay, then the server will fetch the request and serve the client.

The server can make a request from the client as well. It may want to check up on the status of the client, or ask if it has received any security patches, or if it still needs resources from the server. If not, the server will close the connection in order to free up network traffic.

Can you imagine a server standing next to a customer who just stares at the menu without ordering anything? After 15 minutes, it would be a good idea for the server to leave and check on other customers. In both cases, the server moves on to other clients as needed.

Network architecture

THE DESIGN OF COMPUTERS ,DEVICES ,AND MEDIA IN A NETWORK . It is the framework for specification of network 's physical component and their functional organization and configuration , it's operational principles and procedures , as well as data formats used in its operation .

Peer-to-peer network

All computers on the network share any peripheral device attached to any computer . Peer-to-peer network 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 .


IMPLEMENTING A PEER-TO-PEER NETWORK


Implementing a peer-to-peer network typivally involves three steps :

• Install network hardware. 
• Configure the peers and workgroup members .
• Shares resources to the network .
