With the invention of computer and subsequent introduction of Internet, the whole world has become a global village and distance barrier between countries and its people has disappeared once for all. By using various software technologies, products and services were developed and made available to people all over the world. Software technology and Internet has revolutionized each and every component of human life where conventional practices were replaced with modern ones by using technologies.

You cannot single out any human activity which is carried out without using a computer or software service. If you take an example of a common man in a big city or small town, each and every activity he carries out from dawn to dusk is made simple with a software service or product. Different types of computer languages are developed which became the back bones of software and related technologies. Software engineers are leaving no stones unturned as far as upgrading the available technologies are concerned, so as to make human life easier. Software technologies are used in the fields of trade, sports, art, beauty, medical services,travel and the list may be endless. The concept of conventional trade and marketing is replaced by on line marketing where one can trade product and service through his websites. The invention of computer-aided design or CAD is a real breakthrough in the history of modern world and since then CAD has been used for architecture, hardware and software products. Now we are living in a world where you cannot think of leading a normal life without a computer and Internet. It is a common scene in every house hold where people start browsing Internet before brushing their teeth and taking a hot coffee or tea. Looking at the popularity of software services and its increasing demand among all sections of society all over the world, many software service providers entered the field and came out with unique tools and services. The software king Microsoft has become a house hold name all over the world and has made the concept and usage of computer very simple through various software products and services. It is really nice to know that up gradation of existing software techniques are only meant to give more options and comfort to persons who uses them directly or indirectly. Introduction of cordless phones or mobile phones is a landmark development which has helped to make the communication on line. Computer technology is a boon to man kind and you cannot put a stop to its progress. As said earlier, many individual companies as well as multinational corporations started showing interest towards software services and the end result is that some of them became very popular through their unique software service and software products. Among many such players who tried to make a mark on their customers through user friendly products, NVIDIA stood first, which is a multinational corporation based at California in United States of America. Since 1993, NVIDIA has gained popularity among different sections of society through their specialized services like graphics processing units and chip technologies for all types of workstations, personal computers and various mobile devises. NVIDIA received admiration from its customers for supplying reliable quality integrated circuits like graphics processing units or GPUs. NVIDIA is also a front runner in supplying various types of chip sets which are used in graphic cards, video game consoles as well as in motherboard of a computer. Products like Geforce gaming series, quadro series for CAD, digital content creation on your work station and nForce series which are used in the chip sets of an integrated motherboard are marketed by NVIDIA. If you are looking for unique graphics-processors or wireless-communications processors, you can buy them from NVIDIA. They also provide useful product like digital-media-player software. In order to make their graphics processing units more user friendly, NVIDIA, came out with a unique computing engine, popularly known as CUDA or Compute Unified Device Architecture .By using standard programming language like 'C ', a software engineer can have access to CUDA in any of the NVIDIA graphics processing units. Most of the latest drivers available in the market are equipped with CUDA components, which is an indication of its popularity as well as usefulness. Compute Unified Device Architecture smoothly works with all NVIDIA GPUs which includes Geforce, Quadro and tesla line. NVIDIA’s CUDA is the sole technology which is developed buy using C ' language. CUDA is very useful to software engineers and software developers since it allows them to develop software programs in a very short period to solve computation problems which are complicated. The unique feature of CUDA is, it gives access to the native instruction set and memory in CUDA GPUs to a software developer. The programs like GeForce 8 series of Nvidia video cards are workable on video cards developed in future for the simple reason that they are having binary compatibility. Compared to general purpose computation on GPUs, CUDA is having number of advantages. For a software developer, placing CUDA in graphics processing units .is really a gift from NVIDI for the simple reason that it makes his work easier and interesting. Some of the other advantages of CUDA are, easy access to code, shared memory and faster down loads. For a common man who is not having more knowledge about software programing, “CUDA” may be a alien word but as far its advantages are concerned, he should be thankful to the developer of CUDA and NVIDI for ever. If you are fond of videos and maintaining a home theater, CUDA helps you to edit and share videos in a quick time.
