GPS stands for global positioning system, a system that has been established and is managed by the Department of Defense. The GPS system utilizes satellites that have been put into orbit that help people determine their exact location whether it be for the purposes of personal navigation, military activities, or any type of enterprise that requires an exact global positioning by latitude, longitude and altitude. GPS systems are installed in automobiles, motorcycles, some PDAs, Airplanes, dog collars, fishing boats, and so many other products.
GPS systems all started out in the army in the year 1970. In the army, many soldiers needed navigation systems to know their directions around other countries. Without this device it would be really hard for them to find their way around. This device has saved soldier’s time in war and has also saved many lives. GPS systems are very powerful devices and are a great navigation system to use to get around.
GPS systems have gone for beyond just serving the army. They now serve just about everyone. These navigation systems help drivers find there way through city streets and help hikers find their way through the rough terrains of the mountains. They also help pilots find their way around the skies as well as helping mariners find their way around the great sea. The GPS systems technology can help serve anyone in need of it.
GPS systems can also be purchased for motorcycles, and hikers sometimes use such systems to determine where they are while walking. Cyclists should not be left out of the mix, and runners, joggers, and skiers use navigation systems to prevent themselves from becoming lost in an unfamiliar area. Some PDAs - personal digital assistants - are equipped with built in navigation devices, while some Palm devices also include such systems.
Navigation systems are sold with a variety of features and what kind of features you should look for is solely dependent on two factors - price and need. The most basic of navigation systems will provide you with a route from one point to another point or to multiple points, depending on your destination and trip plan. A benefit of such navigation systems is that they not only serve as a guide to your preplanned destination, they also serve as guide back to where you started. Any route you plan in a navigation system is completely reversible thanks to the innovative design of such systems.
Alternatively, you may pay more money for a navigation system that has voice capabilities. You can purchase a navigation system that will guide you to your destination vocally and while speaking to you it will offer up a turn-by-turn dictation of your journey. Conversely, those individuals that spend the majority of their time traveling - like a delivery man may find that they prefer a navigation system that they can preplan many destinations at one time and then move from one set of directions to another. Thus, such individuals require a uniquely designed navigation system -one that possesses multi destination capabilities. Finally, there are different navigation systems for boats, motorcycles, cars, and joggers so you will need to be sure to purchase the product you require for your intended use. The most popular GPS Systems are made by: Navstar, Magellan, Garmin, Slim Trak, Cobra, Holux, Suunto USA, and Timex.

ezinearticles.comIn the world of Information Technology (IT) Management where acronyms and technologies seemingly reproduce exponentially, it is a necessity to be able to separate out the real important issues from the underlying noise. When it comes to monitoring, what really matters is the ability to drill through the noise and determine what in your business is either currently being affected, or what will become affected soon.
There are two basic types of monitoring, fault management (which uses a push model), and network management (which traditionally uses a pull model). Fault management systems use a push model and receive packets of information without requesting it in the form of SNMP Traps, Notifications, and Informs. The senders of this information (the various equipments located on the network), do so whenever they feel that there is something noteworthy, and especially when there is a problem that they are experiencing, whether it be something they themselves are undergoing or something that a neighbor may be reporting to them. One advantage of these fault systems is the breadth of information that is available, as well as the fact that the information simply comes to the SNMP manager. The disadvantage to these types of systems are that typically once the information is sent, it is “too late”, and the problem has already happened. It is generally a “reactive” type of monitoring. At this point, the network administrator or engineer must come to the rescue, either with software tools such as a MIB Browser or real hardware tools such as a screwdriver and a hard-drive.
Traditional Network management and monitoring systems use a pull model, and periodically (typically every 5 minutes), poll the systems in the network for specific statistics and information which may be used later on to correlate data or to run historical reports. The advantage of these types of systems is that they are “proactive”, and allow the admin to make decisions based on the statistics collected and the reports that they can run.
The combination of the fault and network monitoring allows an administrator to have a much more holistic view of the network. Advanced systems can do event correlation to match some of these real-time faults and SNMP traps with data collected from the polling engines, and then real-life business decisions can be made. For example, if a system determines by analyzing historical data that the amount of free space on a hard-disk has decreased more rapidly as of late, and there is a fault that comes in from the online ordering system stating that it cannot take orders online anymore, a correlation engine can determine that the reason may in fact be because the hard-disk has finally filled up and this is preventing the ordering system from fulfilling orders. An even better system would look at trends over time and send a message to a network administrator before the hard-disk fills up, telling them that they have just a couple of days left before this potential problem could happen.
In conclusion, network and fault management are two of the most crucial facets of your IT monitoring paradigm. There are other important facets of IT to manage, like applications and configuration, but both of these fall underneath the umbrella of network and fault in some cases as well. A really good correlation system must have at least basic configuration knowledge, including components of each system monitored as well as the connective and topological layout of the network and systems.

The growth and evolution of information retrieval have been spectacular over the last ten years. Not too long ago, information retrieval could have easily been referred to as a petty discipline in information, whereas today millions of people worldwide experience it regularly. It is safe to say that the Internet is mostly responsible for having driven this revolution. However, the growth of information retrieval has also been brought about by enterprises seeking to network all of their information together.
It goes without saying that all enterprises, whether governmental, commercial, academic or nonprofit, have huge demands on information retrieval. The reason is more than obvious. Most of the information in an enterprise exists in many forms such as documents, HTML pages, media objects and paper, and not in relational databases. In other words, many enterprises are faced with the lack of structure in their information, which can make the information seeking process slow, complicated and expensive. Instead of investing in training, which is a must in the process of accessing information sources, enterprises prefer to reshape their information systems and use information retrieval systems, which are proven to increase the value of information assets in an enterprise. Enhancing the value of the information assets is an achievable goal if enterprises acknowledge the need to add structure to their information and retool their information systems.
While there are some techniques developed on the web that enterprises can adapt and use, most search techniques on the web are not applicable to enterprises. Enterprise search differs substantially from web search because of the different characteristics of the enterprise processes and content. Therefore, Internet search and enterprise search have followed different paths of evolution, and the difference between them is quite substantial.
It is in the best interest of each enterprise to make its information system functional by allowing all available information to be accessed irrespective of its storage format or location. This can be attained by means of a generic search portal. Enterprise search procedures that require elaborate training translate into increased costs. On the other hand, if enterprise search procedures are functional and the search engine technologies that the enterprise employs allow for easy and frequent access to relevant information, costs decrease and benefits increase. To the benefits of all enterprises and organizations, the latest innovations in the area of search engine technologies allow for the enterprise information search process to be fully reshaped.
There are many organizations that deploy enterprise search software. Subsequently, requirements may vary, beginning with software platforms and hardware constraints, all the way to security models, firewall, bandwidth, user communities, document formats and so forth. The ideal solution for enterprise search requirements is the implementation of a search engine paradigm that can be integrated perfectly into the existing information systems of the enterprise. A good example of such enterprise search solutions is DirectInfo, a family of products and services that allows enterprises to easily access their information assets. The specific requirements and deployment needs of each enterprise can be met by the DirectInfo solution, which can be deployed either out-of-the-box or highly customized.
