A network switch is a device that is used to connect devices on a computer network. It allows these devices to communicate with each other and share resources, such as internet access and printers.
Switches are different from hubs, which are older networking devices that simply broadcast data to all connected devices. Switches, on the other hand, use a technique called packet switching to forward data only to the destination device, providing a more efficient and secure way to transfer data on a network.
There are several different types of network switches, including managed and unmanaged switches, as well as switches with different port counts and speeds. Managed switches offer more advanced features and allow network administrators to configure and manage the switch, while unmanaged switches are more basic and require little configuration.
In a home network, a switch is often used to connect multiple devices, such as computers, laptops, smartphones, and smart home devices. This allows these devices to communicate with each other and share the internet connection provided by the router.
