Since Bluetooth can be used with PCs I thought asking this in other computers would be ok.
Someone told me the following and I wanted to know if this is true.
Bluetooth is what wireless is? If it says bluetooth, it is wireless.
If one has a Bluetooth keybaord than why does it use batteries. The person told me whether or not they are plugged into the device batteries are needed because they need a power source to send the wireless signals out to the device.
If Bluetooth is wireless than why would some keyboards plug into the device it's being used with. I always thought wireless meant something didn't have to be plugged into something else to use it.
I found some info about Bluetooth at
Bluetooth - Wikipedia, the free encyclopedia
I had some questions to ask about the link I shared. It talks about paring devices. How does one pair for instance a Bluetooth keyboard with lets say a PC or PDA? Does a code have to be used for both things so the keyboard will only work with one PC or PDA?
