Differences Between Client-Server and Peer-to-Peer network




BASIS FOR COMAPAISON
CLIENT-SERVER
PEER-TO-PEER
Basic
There is a specific server and specific clients connected to the server.
Clients and server are not distinguished; each node act as client and server.
Service
The client request for service and server respond with the service.
Each node can request for services and can also provide the services.
Focus
Sharing the information.
Connectivity.
Data
The data is stored in a centralized server.
Each peer has its own data.
Server
When several clients request for the services simultaneously, a server can get bottlenecked.
As the services are provided by several servers distributed in the peer-to-peer system, a server in not bottlenecked.
Expense
The client-server are expensive to implement.
Peer-to-peer are less expensive to implement.
Stability
Client-Server is more stable and scalable.
Peer-toPeer suffers if the number of peers increases in the system.

Key Differences Between Client-Server and Peer-to-Peer network


1.   The key difference between Client-Server and Peer-to-Peer network is that there is a dedicated server and specific clients in the client-server network model whereas, in peer-to-peer each node can act as both server and client.
2.   In the client-server model, the server provides services to the client. However, in peer-to-peer, each peer can provide servicesand can also request for the services.
3.   In the client-server model, sharing information is more important whereas, in peer-to-peer model connectivity between peers is more important.
4.   In the client-server model, data is stored on a centralized server whereas, in peer-to-peer each peer has its own data.
5.   In peer-to-peer model, the servers are distributed in a system, so there are fewer chances of server getting bottlenecked, but in the client-server model, there is a single server serving the clients, so there are more chances of server getting bottlenecked.
6.   The client-server model is more expensive to implement than peer-to-peer.
7.   The client-server model is more scalable and stable than peer-to-peer.

O LEVEL-PAPER 2nd -- M2-R4 : INTERNET TECHNOLOGY & WEB DESIGN THESE ARE THE QUESTIONS WHICH FREQUENTLY ASKED IN    LAST 10 YEARS ----- Definition of SMTP SMTP (Simple Mail Transfer Protocol)  is a  Message Transfer Agent  (MTA). There are two MTAs  client  MTA and  server  MTA. A  client  MTA at clients system sends mail which is received by the  server  MTA at client’s mail server. Further, the client mail server has  client  MTA which sends the mail from client’s mail server to the  server  MTA at recipient’s mail server.  SMTP is a protocol that defines both client-server MTA, on the internet. SMTP protocol is used in the scenario where both the  sender  and  receiver  of mail must be connected to their mail server by  WAN or LAN . SMTP protocol is used two times,  first  between  sender and its mail server  a...

O LEVEL-PAPER 2nd -- M2-R4 : INTERNET TECHNOLOGY & WEB DESIGN THESE ARE THE QUESTIONS WHICH FREQUENTLY ASKED IN    LAST 10 YEARS ----- MIME Multipurpose Internet Mail Extensions (MIME) is an Internet standard that helps extend the limited capabilities of email by allowing insertion of images, sounds and text in a message. It was proposed by Bell Communications in 1991, and the specification was originally defined in June 1992 for RFCs 1341 and 1342. MIME was designed to extend the format of email to support non-ASCII characters, attachments other than text format, and message bodies which contain multiple parts. MIME describes the message content type and the type of encoding used with the help of headers. All manually composed and automated emails are transmitted through SMTP in MIME format. The association of Internet email with SMTP and MIME standards is such that the emails are sometimes referred to as SMTP/MIME email. The MIME standard def...
