Chloe Tucker. This article explains the Open Systems Interconnection (OSI) model and the 7 layers of networking, in plain English. The OSI model is a conceptual framework that is used to describe how a network functions. In plain English, the OSI model helped standardize the way computer systems send information to each other.

A network hub is a central connection point for devices in a local area network, or LAN. But there's a limit to the amount of bandwidth users can share on a hub-based network. The more devices are added to the network hub, the longer it takes data to reach its destination. A switch avoids these and other limitations of network hubs.
