There are several types of switches including Ethernet switches, managed switches, unmanaged switches, PoE switches, stackable switches, and more.

An Ethernet switch is a device that connects Ethernet devices together within a network by forwarding Ethernet frames.

A managed switch is a type of switch that allows for network administrators to configure and manage the device.

An unmanaged switch is a type of switch that does not allow for any configuration or management by a network administrator. It is typically plug-and-play.

A PoE switch is a type of switch that can supply power to PoE-enabled devices such as IP phones, cameras, and access points.

A stackable switch is a type of switch that can be stacked together to create a single logical unit with increased capacity and redundancy.

Switching is the process of forwarding data packets between devices within a network.

A VLAN (Virtual Local Area Network) is a logical grouping of devices within a network that allows for better network segmentation and management.

A switch port is a connection point on a switch that is used to connect to devices within a network.

A MAC address table is a table that is maintained by a switch that maps MAC addresses to specific switch ports.

A broadcast storm is a network performance issue that occurs when too many broadcast packets are transmitted, causing network congestion and possible failure.

A switch fabric is the internal infrastructure within a switch that allows for the forwarding and routing of data packets between devices within a network.

Port mirroring is a feature on switches that allows for the monitoring of network traffic passing through a specific switch port.

QoS (Quality of Service) is a feature on switches that allows for the prioritization of certain types of network traffic over others.

A switch fabric bandwidth is the amount of data that can be simultaneously transmitted within a switch between devices within a network.

An uplink port is a type of switch port that is used to connect to other switches within a network to extend its connectivity beyond a single switch.

A firmware update is a software update that is used to improve the functionality and security of a switch.

A redundant power supply is a backup power supply that can be used in the event that the primary power supply fails on a switch.

A virtual chassis is a clustering technology that allows multiple switches to be managed as a single logical unit.
