kvm switch

Few years ago i worked at a travel agent company, i was in charged of maintaining their local server and website. The company uses two servers, one handling all emails , users, fax server and the other one is for database and locahost (intranet site). when i got there in the server room was full with keyboards, mouses, and monitors that is sure of taking whole space on the server room. fortunately there is a handy tool called KVM switch.
KVM switch is a device to control a lot of CPU, using only 1 set of keyboard, mouse and monitor. Very useful for servers, or your computer technicians, so i made a proposal to purchase the tool.
Now server room is neat and tidy!
