Answer:
A KVM switch.
Step-by-step explanation:
A KVM switch would be the best solution for a customer to share the monitor, mouse, and keyboard between the two computers assuming he or she has one computer specifically for web services and another for a different purpose.
A KVM is an acronym for keyboard, video and mouse.
Basically, it is a hardware device which enables computer users to connect a keyboard, mouse and monitor (video display device) to several other computers and as such facilitates the sharing of these devices between multiple computers.
