What a network switch does
A network switch connects the wired devices on your network — computers, printers, servers, access points and IP cameras — and forwards traffic only to the port that needs it. Unlike a basic hub it learns which device sits on which port, so it delivers full bandwidth per connection instead of sharing it. Every Ethernet switch here is ex-corporate business hardware, professionally tested and graded, and covered by a 12-month Reboot IT warranty — from $29.
