A network switch is a device that manages the sharing of multiple computers or networks on the same data connection. Another name for a network switch is a network bridge, which is a physical device responsible for routing and processing data within the open systems interconnection model
A network switch can support 10/100 Mbit/s (Megabits per second) or 10/100/1000 Mbit/s port transfer rates. It is possible to have multiple network switches operating at different speeds on the same network. However, this type of setup lends itself to bottlenecks and restricts the possible routes available for the flow of data.
There are four main types of network switches. The four types are unmanaged switches, managed switches, smart switches, and enterprise managed switches. Each different types has its own strengths and weaknesses that need to be considered.
An unmanaged switch is the cheapest option and is typically used in a small office or business. These network switches perform the basic functions of managing the data flow between a shared printer and multiple computers. They can either be desktop models or rack mounted.
A managed switch has a user interface or software offering that allows users to modify the settings of the switch. There are multiple methods for updating the network switch, ranging from a serial console to an Internet based application. This type of network switch requires a knowledgeable user to adjust the settings as needed.
A smart switch is the middle product offering between a unmanaged and managed switch. The user interface is web-based and set with the most popular default settings. Adjustments to one setting result in an automatic adjustment to the related setting.
An enterprise-managed network switch has a wide range of adjustable settings to allow use within a large company or organization. These types of network switches are usually managed by network specialists and are constantly monitored, due to the size and complexity of the network.
