Session, Presentation, and Application Layers Hot
 
Let's look at the upper layers of the OSI seven layer model now. Those layers are the transport, session, presentation, and application layers. The session layer establishes, manages, and terminates sessions among applications. This layer is primarily concerned with coordinating applications as they interact on different hosts. Some popular session layer protocols are listed here, Network File Systems (NFS), Structured Query Language or SQL, X Window Systems; even AppleTalk Session Protocol is part of the session layer.

All Clouds are not Created Equal: The Personal Cloud in the Corporate World (Part 1)
 
Long before Microsoft and every other big technology company declared the intention to go “to the cloud,” the word belonged to the esoteric world of meteorology which, despite its name, is not the study of meteors but the study of that most mundane yet fascinating subject: weather. The weatherman (or woman) knows, though, that the term is a very general one. No two clouds are just alike, and they’re always changing – which can provide hours of entertainment on a lazy summer day as we watch them form the shapes of dragons, monsters and angry old men. There are many different types of clouds: Nimbus, cirrus, cumulus and so forth. Each has specific, well-defined characteristics.
