Types Of GPS Devices
The Global Positioning System – or GPS – has transformed how the world finds its way. It’s no secret that the popularity of GPS has made it a standard feature in many a car. But in truth there are quite a number of GPS devices that are used in today’s modern society. What began as a government experiment and then a standard device used by the military, is now more popular than ever in civilian society.
When Russia launched Sputnik in the late 1950′s we had our first glimpse into the role that satellites would play in our future. Those who were monitoring Sputnik found that they were able to pinpoint its location based on the radio waves it provided. The seeds of GPS were born.
In the 1960s the U.S. Navy began experimenting with the technology, using the positioning of six satellites to help missile-carrying Navy submarines pinpoint their location. But the Global Positioning System that we know today was designed and implemented by the United States Department of Defense; the first operational satellite was launched in 1978 and by the mid 1990s there were 24 satellites – all of which are still in operation today.
The byproduct of this new technology has been GPS devices, designed to harness the power of satellite navigation to offer the highest level of convenience. It seems as though every year more GPS devices hit the shelves and in so doing they become part of what’s expected in society. The types of GPS devices are varied and your choice to use them depends largely on your frequency of need.
One of the more popular GPS devices is GPS mapping that allows you to visit any number of websites and enter any address in the world. If satellites have access to this area, you are immediately given a satellite picture showing the precise location you requested. For mapping trips, these GPS devices can take information downloaded from your computer and put it to use in your car, giving you detailed directions for the most expedient trip.
Another one of the more popular GPS devices is a GPS navigational unit. These units can either be mounted in your car or come in a portable system that you can transfer from vehicle to vehicle. Once a destination is entered into the GPS navigational system, it can literally walk you through your trip telling you where to turn and the time and distance relative to each portion of the drive. Some navigational units offer a feature whereby you can find restaurants, shopping, hospitals, and accommodations regardless of where you are; this can be incredibly useful when hunting services in a town with which you are unfamiliar.
GPS tracking, another of the GPS devices, allows you to track another person or thing. Many parents use GPS tracking in the cars of their teenage drivers. Others use this system to help protect precious items that are in danger of being stolen.
No matter which of the GPS devices you choose, you will no doubt find GPS to be an essential part of your life before long.

What types of devices would you use in this network?
What types of devices would you use in this network? What benefits would you gain from using switches in the labs rather than hubs? When might these be important?
*Arctic University is opening a new satellite location and it has been decided that it will use a combination of Ethernet and wireless networks. The location will be composed of 4 computer labs, 20 classrooms, and 50 offices for administrative staff.
From what I know, switches doesn’t allow for internet connection. It cannot relay internet connections to whatever computers connected to it. It merely connects these computers together for INTERNAL network. Hubs on the other hand can allow for internet connection sharing.
I’d would think using hub would be better to gain excess to external stuffs on the net.. information etc.
Cheers

You would need switches/hubs in the labs and offices, Wireless Lan access points in the classrooms, a router to connect each of these devices to the external world. The external world connection could be a satellite connection OR a fiber optic inter-continent connection.
The primary difference between a hub and a switch is that a hub provides a shared medium for all its users. Hence, only one station can talk (send or receive) at a time – others have to wait for him to stop talking before they can speak. Switch provides a dedicated segment for each of the stations that are connected to it. Thus, half the stations could be sending data to the other half simultaneously.

My first concern is what type of work will be done in the labs? If each person is going to be needing a lot of processor speed, graphics, and memory, then I would go with switches. If the labs are going to be using regular applications, then I would use hubs. The best way to think about it is a switch provides a direct connection, where a hub shares its connection.

Simplest answer…do NOT use hubs. That is the equivalent of buying VHS tape player over a CD player. Switches are faster, more intelligent and more versatile. Plus the cost is about the same as a hub nowadays.
