Switches are a key component of many business networks, as they connect multiple PCs, printers, access points, phones, lights, servers, and other hardware. Switches allow you to send and receive information (such as email) and access shared resources in a smooth, efficient, highly secure, and transparent manner.
What is an unmanaged switch?
An unmanaged network switch is designed so that you can simply plug them in and they work, no configuration required. Unmanaged switches are typically for basic connectivity. You'll often see them used in home networks or wherever a few more ports are needed, such as at your desk, in a lab, or in a conference room.
A network switch is a hardware device that channels incoming data from multiple input ports to a specific output port that will take it toward its intended destination. It is a small device that transfers data packets between multiple network devices such as computers, routers, servers or other switches.
In a local area network (LAN) using Ethernet, a network switch determines where to send each incoming message frame by looking at the physical device address (also known as the Media Access Control address or MAC address). Switches maintain tables that match each MAC address to the port which the MAC address is received.

What is a managed switch?
Managed switches give you greater security and more features and flexibility, because you can configure them to custom-fit your network. With this greater control, you can better protect your network and improve the quality of service for those who access the network.
How does a network switch work as compared to a hub?
In the most basic networks, devices are connected with hubs. 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, the longer it takes data to reach its destination. A switch avoids these and other limitations of hub networks.
Network devices can be separated by the layer they operate on, defined by the OSI model. The OSI model conceptualizes networks separating protocols by layers. Control is typically passed from one layer to the next. Some layers include:
