Study Notes
Application Layer
- Examples of programs that run on the application layer include email clients, web browsers, and file transfer applications.
- File Transfer Protocol (FTP) is commonly used for transferring files on the application layer.
SMTP
- The main purpose of SMTP (Simple Mail Transfer Protocol) is to send and receive emails.
HTTP
- HTTP (Hypertext Transfer Protocol) is used to transfer web content, including HTML, images, and other multimedia files.
- HTTP is commonly associated with accessing web content.
Application Layer Activities
- Typical activities performed at the application layer include sending and receiving emails, transferring files, and accessing web content.
Client-Server and Peer-to-Peer Models
- The main difference between the Client-Server and Peer-to-Peer models is that in the Client-Server model, a centralized server provides services to clients, while in the Peer-to-Peer model, peers act as both clients and servers.
- In the Client-Server model, a client process initiates communication, while a server process waits to be contacted.
- In the Peer-to-Peer model, peers can act as both clients and servers, and communicate with each other directly.
- The Client-Server model is generally suited for large-scale networks, while the Peer-to-Peer model is more suitable for small networks with fewer than 10 computers.
- A characteristic of the Peer-to-Peer model is that new peers can bring new service capacity as well as new service demands.
- In a Peer-to-Peer network, peers can provide services to each other, and communication occurs within the same host.
- The Client process in the Peer-to-Peer model acts as a client when requesting services and as a server when providing services.
- The Peer-to-Peer model is generally considered less costly compared to the Client-Server model.
