Part III - So what am I looking for?Probably the last question you need to ask yourself. Weigh up between image (size, shape, style, colour), performance (play time, memory, compatibility, gizmos, other functions) and quality (useability, interface, design, battery life). Work out what's important, and Google or eBay will do the rest for you (or if not, then your younger brother or sister will also suffice). There is always a cheaper price for something, but there is always more hassle to get something that you want exactly. If you've ever bid for an eBay item, then found something way cheaper than what you've just bought, then you'll know what I mean. Look, if you're going to spend money (any amount of money), then it's important to at least pick something that works long enough for you to at least look the part, and one that you won't throw out the window because that's all it's good for. Therefore, battery life, memory, interface and compatibility should not be taken lightly. Part IV - So what do I do with it?You've got yourself an MP3 player, so what's next. Well, you can use it as a fashion accessory, play some MP3 music, or just leave it sitting in the closet until a better model comes out. It's hard to say unless you've got one, and once you've got one, you'll work out what to do with it. Sometimes it's an expensive lesson to learn, but most times when you spend money for something, you invariably find a use for it, even if it's just another item on the eBay used section.Useful advice? Well, don't just take my word for it, because even bad advice needs to be taken to be believed. Take these suggestions into account when you are choosing your mp3 player, and you'll be well equipped.
GPS Units make sure you know where you are going no matter where you are. Gone are the days of getting lost easily. A GPS system can cost under $100 for a less-than-fancy model. However, what your GPS Unit looks like is not as important as what it actually does.The GPS receiver is a handheld, sometimes portable device that works with the Global Positioning System (GPS) network. The GPS network is comprised of 27 satellites that constantly orbit the earth. As the earth rotates, so do the satellites. Of these 27, 24 of the satellites actually work, while three are used as backups. As you can imagine, running the GPS is quite costly.The GPS network was originally developed by the United States military. The military used it to increase navigational accuracy. However, it was not long before the GPS network was open for use by anyone.How it works is simple. First, the satellites have multiple orbit routes around the earth. At any one moment in the day, at least four of the satellites are able to transmit information from the satellites to GPS receivers. Of course, it is imperative that the view between the satellite and the GPS unit is unobstructed. That is why GPS receivers sometimes do not work right in areas with high mountains, a lot of trees, or skyscrapers in the way.GPS receivers work with the satellites. First, the GPS hunts down four of the satellites that can connect with and transmit information to the GPS unit. Once four satellites have been found, the distance to each of the satellites is recorded, and the GPS can pinpoint its location, by the distance it is from each satellite.This mapping and estimating is based on a principle in mathematics, which is known as trilateration. How it works is by traveling through three-dimensional space. This is complex to understand, but the result is amazing, and it should be what you look for when purchasing a GPS unit of your own.Trilaterion that works in 3-D is what is used to map your location. A series of spheres line the distance from one place to the next, based on the location of the satellites at the time of the transmission to the GPS receiver. The spheres intersect and meet and as the distances from different locations on different spheres are measured, your exact location is pinpointed. All of the four satellites' plots work together, to intersect in one place through the spheres.GPS receivers generally try to use more than four satellites at one time. This provides a more accurate location and less room for error. The Earth is also used as a marker, which works with the GPS network to help pinpoint locations on the surface of the planet.GPS receivers have to know how far a distance it is from the satellite to the unit. To do this, radio signals sent from the GPS satellites are analyzed. These signals are high in frequency though they are relatively low in power. The better your GPS unit is the better chance you have of using multiple satellites in order to pinpoint your exact location.Since radio signals travel at the same speed light does, GPS receivers are able to determine how fast the waves travel and how far they have traveled. At random times, the satellites transmit pseudo-random code, which are digital patterns, to the GPS receivers. The GPS unit will then play the digital pattern, though there will be a lag. This lag is based on how fast the signal traveled, and is a major part of the GPS plotting process.In order to track the signals pattern, the satellite and the GPS receiver use clocks, which synchronize together. The Satellite uses an atomic clock, while the GPS receiver uses a regular clock. However, to accommodate synchronization, the clock in the GPS unit is able to constantly reset. This prevents any type of clock problems from occurring.There are various types of GPS systems. These systems work to fix any inaccuracies and errors in the GPS receivers location tracker. These systems include WAAS and DGPS.
The definition of a cheat is pretty easy to figure out. If you have an affair with someone other than your lover, you can be called a cheat. If you copy answers from another person during an exam, you can also be called a cheat. In sports, if you try to win or get an advantage by disregarding the rules you are cheating but in computer games this definition become hard to follow. Taking advantage or lying to your fellow game players does not automatically mean you are cheating.Cheating in a computer game is defined by the game and the people who are playing it.A lot of "computer games" come with a cheat code. This is usually to help a person get started and makes the game a little easier. They are usually designed for a single player. If you use these cheat codes you are cheating technically but it doesnt mean you have an advantage.The most common occurrence of cheating is when there are multiplayer and mass multiplayer games through the internet. In this instance, the players are not known to each other so they dont have the restrictive influence of being seen by their opponents.There are two main areas of cheating in computer games. You can change your settings through the use of exploits, bugs and external software or cheesing.If you alter your computer settings, the layout of the computers hardware or the computer game to fit your gaming style you are cheating in a sense and this can be alright. But if you went even further and changed the brightness or the color of the screen in order to see better in shadow areas it becomes questionable.Exploits are termed as errors in the game itself that give an advantage to one person or another. If someone deliberately uses those it a game, it could be considered cheating but it also could add to the excitement of the game.There are software programs you can purchase that modify a program that runs computer game. This is a more serious form of cheating. Other software programs study the status of the game through the computers RAMAnother form of cheating is called cheesing. This is when the players do things that cannot happen in real life or are not allowed in real life.The most common of game cheats these days find ways to change the games software. Even if the game developers try to encrypt or protect the files, there are software programs that will be able to change the games code without changing the main program. Cheats of this kind may be detected using programs that are installed on a server.Preventing computer game cheaters is not easy. There are a lot of grey areas to agree on and consider before you term someone a cheat.
Close to 1200 companies are now providing Voice over Internet Protocol (VoIP) service in the US and Canada. Despite this figure more and more cable companies, DSL operators, and telecom majors are moving to this technology, most likely because they realize that VoIP is the future of telephony. They also likely realize that the market is still wide open, making now the best time to capture it.The success of VoIP services can be boiled down to two factors. Cost is the first factor. Unlike conventional telecom companies, VoIP companies do not need to invest in expensive infrastructures because the Internet serves this function already. This means they can start and run a phone service at a tiny fraction of the cost of a conventional telecom company--a savings that can be passed on to the consumer.This allows VoIP companies to make a profit while charging rates that are comparatively very low. In fact, some VoIP companies offer call plans starting as low as $9 a month. Furthermore, most of VoIP companies offer unlimited calling across the US and Canada. The end result is a phone bill half that which the average phone subscriber is likely to pay for conventional telephone service.The second factor to the success of VoIP services is all the low-cost or no-cost added features. The average VoIP phone comes with a plethora of useful features. These features likely include caller id, call-waiting, three-way calling, call blocking, distinctive ring, international call forwarding, call waiting disable function, repeat dialing, return dial, call filtering, sequential ringing, secondary virtual phone number, additional service lines, toll-free numbers and Web-based management.This is a massive improvement over the features offered by most conventional services, and since they are usually provided at no additional charge by VoIP services the customer is getting a phone service that not only costs less, but also offers more features. More and more Americans and Canadians are switching to the VoIP services for just this reason. The only additional expense is the up-front cost of the installation of a broadband cable connection or a DSL line, which of course many already have for their computer connection.Initially the VoIP services were limited to the geeks of the world, who used telephony software that was available free on the net and ran on a computer. This option never gained popularity because the voice quality was usually poor and the service only allowed calls to be made from computer to computer. The requirement for both users to be online and in possession of similar software in order connect over VoIP was a serious limitation.Once the infant VoIP software was modified to allow connection to specialized or standard phones through adapters it became possible to call from one phone to another. It was then that the potential of VoIP was realized. When companies like Vonage launched an aggressive campaign to woo traditional phone subscribers the technology got a significant further boost. After that the market absolutely exploded.
You have heard it all-everyone is talking about the VOIP technology and how it is outpacing the telephones companies and even the cellular companies. So what is all the talk about? VOIP allows you to make your entire local, long distance and international telephone calls over your high-speed internet connection. All of this for just one low price that can be rolled up into your monthly internet cable invoice. The technology is changing rapidly and there are a lot of new features available to people savvy enough to get in on the ground floor for this new technology.So, what should you do? How different will your VOIP technology be over your regular telephone company? If you listen to the advertisements, you will realize that they are a lot alike, but there are also some benefits that VOIP technology now offers.For your VOIP telephone phone, you can have voice mail, 3-way calling, speed dialing, call forwarding, simultaneous ring, call waiting, caller ID, call return, caller ID block, anonymous call rejection, do not disturb feature, and last number redial. If changing to the VOIP system you can take your existing telephone number, get great international rates, make it possible for people overseas to call you with it being a local call for them (gone are the long distance rates), you get free in-calling network and can manage your account online.Well, this sounds a lot like the other phone companies, so what really makes the VOIP technology better? It is debatable as to whether or not this is better. It is definitely different, however; recently, there was a press release on http://News.com that "A technical review conducted by the British government has found several security flaws in products that use VOIP and text messaging, including those from Microsoft and Cisco Systems." So, there can be a problem with the VOIP technology.There is also concern that the VOIP does not full support their own encryptions yet. This means that it is easy to eavesdrop on VOIP telephones and to even change what is being said. Experts are working on security options, but have not yet found one that is completely reliable to take care of this problem.If you look at it only one way, you would say, this is a major problem and I can not deal with that. However, consider the cyper terrorists. They can and will disrupt any communications system-all it takes is the time and patience to find a single flaw and everything can come crashing down.The choice is yours to decided whether or not the VOIP technology is advanced enough for you to use this as your primary means of communicating on the telephone. Take your time and really think about whether or not this new VOIP technology will do everything you need it to do. If not, you might want to wait a few years until the technology has advanced more before changing over to the new VOIP technology. You know that technology will only change and be improved for the better.
