Bluetooth is a very strange term and it catches people by surprise. If you’ve been looking at new laptop or maybe even a new cell phone then you probably have heard the term Bluetooth. For some reason salesmen aren’t that smart when they come to describing this technology. They prefer to just say Bluetooth because it sounds cool and assume that you’ll like it. At least from a selling point, you should be told about the features(特征),but rather the benefits that you’ll get from it. I think I should explain to you what Bluetooth is.
When you get down to the explanation, it’s just radio frequency①. It allows you to operate things in a completely wireless manner. For example, if you were using a cell phone and wanted to connect a headset to it, then you would do that with Bluetooth. There will be no wires or anything like that; besides, it is done quickly and cheaply. The big selling point for this particular type of wireless signal is digital. This means that the signal going from your phone to the headset can’t be let out.
The same can be true for computers. Let’s say that you want to connect your computer to your cell phone because you want to get some pictures from it. Well, you can just connect with a Bluetooth connection and you can access② all the files you want. It is really that easy.
If you’re going to get some sort of wireless technology you should really go with Bluetooth. It is the most popular and this will help save you a lot of time.
