The websites I have chosen were about Garmin, which is a GPS (Global Positioning System) and about computer networking which is wireless networking. I have heard of a GPS before. I have also used one before. They are great for navigating. A wireless networking is also very useful.
Most people misunderstand what a GPS really is. It is very technical and uses three different signals for imformation. The three signals are, a pseudorandom code, ephemeris data, and almanac data. The pseudorandom is the I.D code, The ephemeris data signals and is transmitted by the satillites, and the almanac tells the GPS receiver where each GPS satellite should be at any time during the day.
In experience, using a GPS is very asurable. It is acurate 90% of the time. It tells you the time, arrival time, the miles, and it even tells you the speed limit on the road; depending how high tech your GPS is. I think everyone should have one.
Wireless networking is usefull in very many ways. This networking could be used in a home or at a business. What great about it is, it's very small and portable. Also, a lot of people can use it. It says about 255 clients could use one wireless networking at one time. Its something indeed used for computers and internet access. This could be why its also called a base station.
