Study Notes

Application Layer Network

The traditional application of the application layer network is to provide services and interfaces for applications to communicate with each other.

Communication Between Processes

Processes running on different end systems communicate with each other using application-layer protocols.
Processes running on the same system communicate with each other using inter-process communication (IPC) mechanisms.

Protocols and Their Uses

SMTP (Simple Mail Transfer Protocol) is used to exchange e-mail.
HTTP (Hypertext Transfer Protocol) is used to retrieve web pages from remote servers.

Role of the Application Layer

The application layer provides services to end-user applications, such as e-mail, file transfer, and web access.
The purpose of the application layer is to support functions such as process-to-process communication, directory services, and mail services.

Examples of Traditional Applications

Examples of traditional applications of the application layer network include e-mail, file transfer, and web access.

HTTP Role

HTTP plays a crucial role in the application layer, enabling the retrieval of web pages from remote servers.

Widely Used Application Protocols

Widely used application protocols include HTTP, FTP (File Transfer Protocol), SMTP, and DNS (Domain Name System).
