What is a network switch and how does it work?

A network switch is a device that connects multiple devices within a local area network (LAN) and uses packet switching to forward data to its destination. Unlike a hub, a switch sends data only to the device it’s intended for, improving network efficiency and speed.

What is the difference between managed and unmanaged network switches?

Managed switches offer advanced features such as network monitoring, traffic management, and configuration options, making them suitable for complex networks. Unmanaged switches are plug-and-play devices without configuration options, ideal for smaller or simpler networks.

Can I use a network switch to expand the number of Ethernet ports on my router?

Yes, connecting a network switch to your router allows you to expand the number of available Ethernet ports, enabling you to connect more wired devices to your network.

What are PoE (Power over Ethernet) switches?

PoE switches can deliver both data and electrical power over the same Ethernet cable to devices like IP cameras, wireless access points, and VoIP phones, eliminating the need for separate power supplies for these devices.

Are network switches compatible with both wired and wireless networks?

Network switches are designed for wired connections, but they can be used alongside wireless access points to help create a seamless network that supports both wired and wireless devices.
