Application Layer Model of OSI Protocols
Application Layer Model of OSI Protocols It is a fundamental part of the functioning of computer networks. This layer is responsible for communication between software applications and the underlying network infrastructure. In this article, we will explore in detail the protocols of this layer, its importance and operation. Understanding how these protocols work is crucial for any network and systems professional, as it directly affects the way applications communicate over a network. Join us on this tour of the OSI Model Application Layer Protocols and discover everything you need to know to understand the complexity and operation of computer networks.
– Step by step -- Application Layer of the OSI Protocols Model
- The Application Layer Model of OSI Protocols It is the last layer of the OSI Model, it is responsible for providing network services to software applications so that they can communicate with the network.
- This layer includes protocols that are used by applications to send and receive data over the network.
- Some of the protocols The most common in the Application Layer are HTTP, FTP, SMTP, POP3, IMAP, DNS, Telnet, SSH, among others.
- The HTTP protocol is used for the transfer of web pages over the Internet, while FTP is used for the transfer of files.
- Email protocols such as SMTP, POP3 and IMAP are used to send, receive and access emails, respectively.
- The DNS protocol is responsible for translating domain names into IP addresses, so that computers can find the requested servers.
- On the other hand, Telnet and SSH are protocols that allow remote access to other devices over the network.
