As it is known, every level in OSI model communicates with levels that are below and above it. The task for the presentation layer is to receive data from the application layer and translate it so application on the other side of connection would understand it. It converts the non-text data like images, pictures, photos, sounds, music, and videos to the form that allows workstation on the other side of network connection convert it back. If we take the example of loading the web-page, the presentation layer on the server side would convert images and other media that are on the page to the form understandable by users browser.

Second important feature of the Presentation layer is the data encryption on one side, and decryption on the other. When the application or a web browser is establishing secure connection with the server, it is achieved using Presentation layer of OSI model.
