A KVM switch allows you to control and manage two or more PCs simultaneously. Apart from PCs, these devices can be used to control servers such as print and domain servers.
An important distinction between them is that the KVM switch controls nearby devices such as those located in the next room or the same building.
Console servers allow users to control a wide range of network devices located both at local and remote locations. Console servers can control and manage servers, Firewalls, routers and more.
