(This is not a spam question or a homework question)
I was wondering would you please explain to me in a simple way that I can understand: how does a wireless mouse and keyboard lose their connection?


Thanks for writing! How Stuff Works has a very extensive article on BlueTooth, the technology that currently allows most computers and peripherals to communicate with one another:

More to your question, a BlueTooth connection can be interrupted or lost.  Here's how: (lifted directly from the article) "A number of devices that you may already use take advantage of this same radio-frequency band. Baby monitors, garage-door openers and the newest generation of cordless phones all make use of frequencies in the ISM band."

BlueTooth devices send very weak signals to avoid interference with these devices, but if you have a more powerful device (cordless telephone right next to your computer), it may temporarily lose connection.

You may also lose connection if your peripheral (mouse, keyboard) go into low-power or sleep mode, or if your computer does this.  Clicking the mouse a few times, or the same on the keyboard, usually fixes the issue.

I hope this helps!

I worked in IT for ten years with a specialty in Macintosh technologies and Project Management.
I've worked with the Macintosh Operating system and various machines since my first PowerMac 8500 running Mac OS 7.5.3 in 1996. I support my friends and family in keeping their Macs healthy and upgraded. Now I use a MacBook Pro for our home media network and we're pretty much down to iPads and iPhones for daily use.
Most important: I've also worked on PCs for a number of years with various flavors of Windows(95,98,NT4,2000,2000Server,2K3Server,SBS 2K3Server,Mil,XPHome,XPPro, Vista Business), but I've always used the Mac as my platform of preference.
