Switch
A network device that connects devices within a local area network and directs traffic between them.
What does it mean Switch?
A switch is the basic building block of a network. Computers, printers, access points, and servers are connected to it.
Managed switches allow for VLAN segmentation, traffic prioritization (for example, for telephony), Power over Ethernet (PoE), and port status monitoring.
Unmanaged switches are cheaper but do not allow for segmentation or monitoring; in a business environment, they are at best suitable as a temporary solution.
Practical examples
A company with IP telephony uses switches with Power over Ethernet, which eliminates the need for separate power adapters for phones and access points.
Business relevance
High-quality managed switches are a prerequisite for network segmentation, which is one of today's key security measures.
Common mistakes
The most common mistakes include daisy-chaining cheap switches under desks, unlabeled cables, and the absence of a backup device in case of failure.
