APPLICATION LAYER

The OSI model defines the application layer as being the user interface. The OSI application layer is responsible for displaying data and images to the user in a human-recognizable format and to interface with the presentation layer below it.

Examples of applications that utilize the network are:

• Telnet
• FTP
• Instant Message software (AIM, MSN, ICQ, Yahoo)
• Microsoft Windows File Shares
• Web Browsers (Internet Explorer, Firefox, Google Chrome, Safari)
• Network games of Doom, Quake, Unreal (first-person 3D shooter video games)
• IRC (mIRC)
