In this new revolution of IT world most of the organizations are focusing on a single solution that is “Custom Software Development”. Every enterprise needs unique solutions so that they can put their business processing ideas into practice. Custom software development meets all these requirements for business enterprises so that they can deliver unique solutions for their business processing. These days each and every firm whether it is small or big is different in terms of functions so they require such type of solutions that results better productivity and portability. To fulfill all these requirements custom software solution plays a vital role.


In this business competitive edge, custom software development provides tailor-made solutions to fulfill their customer’s needs. We cannot ignore the significance of customized software just because of it is not only made on the basis of requirements but also client’s preferences. The motive behind developing custom software is that they can be used by a single client or a group of clients but not for the masses. Tailor-made software is made with the consent of its client so the chance of error seems to be very less. If there is any problem or complication regarding software emerged then modification can be done at the time of development.

The main advantage of using custom software is that it provides a kind of flexibility for an enterprise which needs to be update and modify its functionality with this modern era. Because if you want customer’s satisfaction then you have to use client oriented approach for getting best results. These software are not developed with the intention of focusing majority of the market, they are designed and developed for those who want unique business solutions according to their planned budget, time and resources available.

There is no doubt that development of custom software becomes very handy for your business that brings better productivity and portability. Because designing good software a developer must follow certain protocols such as going through the business requirements, proper execution of plans and following standard software development life cycle at every stage of software development. So you should be very conscious while approaching a software developer or enterprise to make a comprehensive solution for your business firm. Though, in this competitive rat race every company which makes custom software should have a dedicated and technically sound team so that they can design best software that ensures higher degree of performance with customer’s performance.

However designing custom software can be expensive but on the other hand pre-developed software will not be able to fulfill customers’ requirements.

OEM stands for original equipment manufacturer and the phrase "OEM software" refers to that software that is sold under licence to computer producers or computer seller in order to allow them to pre-install the respective software on the computer they are about to sell as a bundle. This OEM software is purchased by the computer manufacturer or seller directly from the software producer or from its distributors.

By doing this, those who sell the bundled computers with pre-installed software get a serious discount, as they buy large numbers of licences - of course the number of licenses has to correspond directly to the numbers of systems they sell. This way all parties win: the software producer gets to sell its product 's licenses, even if for a smaller price that if they had waited for the end user to purchase the license for every computer, but it saves a lot of time and the costs are recovered because they sell big quantities.

The OEM software can only be purchased by authorized computer sellers that assemble computer systems as bundles and it must be installed only by the purchaser. The end user will only use the software that was already installed on the computer when they bought it. The end user can't purchase OEM software, but only use it. However, if the end user wants to replace the existing pre-installed software with some other version of the software, they can do it only if they replace it with another licenced software. But I am afraid in this case they will lose the right to the assistance and support offered by the computer seller.

But why would they bother buying and installing OEM software on the computers that are about to be sold in the first place?Well, first of all every software application that is installed on every computer must consider its technical details and see if the software is compatible with the computer features, because this isn't always possible. It is the responsibility of the person installing to software to take care of this part.

And if you want things to be perfect the guy doing this must be a professional, because otherwise you can do harm to your computer. Then it is about installing the operating system and all the software of all the computer components and all the necessary drivers that must be installed by someone who knows what is doing there. But this is also a marketing tool because the client has the possibility to see what the computer is like, the way it works even before purchasing it. Besides, the buyer can use the computer right out of the box, without the trouble of installing all the necessary stuff. As a bonus, they will also get assistance and support in case something happens.

The only problem is that the end-users must buy the configuration that is already made by the producer. and use it like this. But I don't consider it an inconvenient, as they usually make the best possible combinations, as they are professionals. The OEM software that is pre-installed is also guaranteed and you know for sure it is not a free trial that will end in a few days and you are also spared the trouble and expense of purchasing a new software license that is expensive and needs to be installed. Just make sure you get the genuine software and not some fake pirated version.

GPS (Global Positioning System) is a U.S. space-based global navigation satellite system. Nowadays people from all over the world, not only USA uses this reliable system that offers positioning services.
<-300x250 Medium Rectangle - center->
GPS has three major components: satellites (between 24 and 32) that orbit the Earth, four control and monitoring stations in different parts of the Earth, and the GPS receivers owned by users. GPS satellites send signals from space that are used by GPS receivers to provide three-dimensional location (latitude, longitude, and altitude) plus the time.

GPS is now a valuable aid to navigation worldwide, and a useful tool for map-making, tracking and surveillance. GPS has become of real help in all transportation systems worldwide, in the air, on the ground or on the sea. Not to mention emergency services that use GPS to locate the victims of accidents or disasters they are supposed to rescue. The accurate timing provided by GPS is an important tool in all activities of our lives. But GPS is not used only by professionals. Normal people from a variety of fields use it on a daily basis to ease their life.

The first navigation system that used a satellite was called Transit and was tested in 1960 by US Navy. Five satellites, but they could only provide a navigational fix once every hour. In 1967it was followed by Timation, a satellite that placed accurate clocks in space, a technology that GPS relies on. Then, during the 1970s Omega Navigation System was developed - the first worldwide radio navigation system. The system became more and more accurate as they introduced atomic clocks in artificial satellites.

The first GPS devices were built according to the model of the radio navigation systems such as LORAN and the Decca Navigator that were used during World War II.

So the early days of the GPS were only known by the army and a few scientists. And it was used in military and political problems. But then there was an unfortunate event in 1983 that allowed this technology to be used by civilians, too. That was the shooting down of the Korean Air Lines Flight 007 because it got into the USSR's prohibited airspace. President Ronald Reagan then decided that such things should be avoided and GPS use became part of common use. The first satellite was launched in 1989 and the 24th and last satellite was launched in 1994.

Initially only the military staff had access to the highest quality and the signal available for civilian use was intentionally degraded ("Selective Availability", SA). This stopped in 2000 and improved the precision of civilian GPS from about 100m to about 20m.

A GPS receiver regularly receives signals from the satellites and in this why it is capable of calculating its position on Earth. All the messages sent by GPS satellites contain information about the time when the message was sent, the precise orbital information and the general orbits of all GPS satellites.

The exact position of the GPS receiver is calculated using at least three satellites because there are three dimensions of space. However, even a very small clock can cause a large positional error. That is why receivers use four or more satellites to find out the exact location and time of the receiver. Most of the people who use GPS technology are not interested in using the exact time, but only location. Only some specialized people use this kind of applications like time transfer, traffic signal timing, and synchronization of cell phone base stations.

GPS navigation software usually deals with one of the following two categories: navigation and route tracking. The navigation feature allows you to establish an itinerary and gives you clear instructions how to get there. This software is based on a vector -based map, usually for cars or other motorized means of transport. Navigation tracking allows you the route that you followed or will follow in the future and usually shows a map with a red line on the screen; you must follow this line in order to get to the targeted place or represents the trip you have already made.

These two types of software are seldom offered in the same package.

Track - A track is a trace of the places you have been to with your vehicle (often called a "breadcrumb trail"). The software of your GPS unit receives your position and time and records this data as points on a map. If you want to see this track, all you have to do is access the memory of your GPS and the display will show the itinerary taken as a series of dots or a line connecting the dots on a map.

Route- the software shows you the recommended itinerary for the trip you want to take. You introduce a set of information such as starting point and finish point and, according to this data the screen displays you the best route to follow. It is very similar to the first feature of the GPS presented above, except the fact that the first one is in reverse.

Waypoints are used to mark particular locations, important cities, towns or relief forms you meet on the way to your intended destination. They are used only as reference and guidance because sometimes there are different routes from one place to another and waypoints help you follow the right path.

You can use this software on a laptop computer with GPS receiver attached to it. You should know that most GPS software that you find in shops is compatible only with Windows and Mac OS X, yet some can support Linux as well. However, it is easier for you to use the GPS software on your palm, PDA or smartphone. These devices can also be used as a wireless modem for a computer; so that you can upload the information about the route you want and download the recommended itinerary.

The GPS software you can find in stores differs only by means of maps available. Some of them have embedded maps (Nav N Go, ROUTE 66,TomTom Navigator, TomTom Mobile, Destinator, Garmin nRoute, Garmin BaseCamp - released in March 2009, GPS Tuner, Microsoft Streets and Trips 2009). Others have an open source and free navigation software with maps (OpenStreetMap). There is a kind of navigation software with scanned or downloaded maps stored in the computer (Master Navigator Software, OziExplorer). And finally Navigation software with maps downloaded from a remote server: Google Earth (Windows, Mac, Linux), google maps, GPS Tuner (Version 5.x on Windows Mobile, Smartphone), Navit, VZ Navigator (smartphone)
