Why do we use software development? Well this is done for one main reason and that is o provide value and growth to the user's requirements. The basic fundamental lies in the fact that the user requirements and needs or marketing goals have to be created or converted into good software application. So essentially, what software development does is that it permits the end user to carry out tasks he/she wants to do.
It is used to carry out all functions according to the need. What has happened do far and what we have learnt from it is that the requirements of software development will continue and these requirements may also increase as the market tends to develop. The entire world is shifting from traditional style workmanship to a techno savvy work environment. More and more companies are now being restructured with advance technology and IT services. As such, to acquire the latest in technology, software development has become the main means of doing business in the world today also resulting in the flourishing growth of the IT Industry.
So how it essentially goes about is that it helps you keep the latest hands-on technology at minimal cost. Hence, we can say with a lot of surety that IT companies are flourishing high because of the increased need of software development services. We see here how IT companies and software development are inter-linked.
One's boom causes the other to rise. Many companies are therefore offering services in software development. As new development processes are explored in the world, software development will have unbounded growth. This is how much software development means to the world today. The applications that software development have to offer comprise of a host of extremely complicated machines for different purposes including so many industry types and just about anything you can think of.
As you got to your office, you will also discover how offices are trying to make their work paperless and software development is playing the main role to get to achieve this target.

Super Mario - a Short History
Super Mario is a classic game series created by Nintendo Entertainment System. It stars an Italian plumber called Mario and his brother Luigi. In most of the games, players are required to finish each level to be able to proceed to the other. In one of the games, the objective of it is to save Princess Peach from the hands of Bowser which is the ruler of the Koopas. The game could be played by two players as well as one.
Super Mario Bros could be considered one of the most successful games ever created as it has more than 40 million copies of it sold. This game may be the backbone of Nintendo’s success in the gaming world as it survived during the video game crash during the 1980s. Due to the overwhelming success of Super Mario, the Mario Brothers are officially Nintendo’s highest known mascot. Even its theme music is well known by a lot of people. It has been well used by a lot of video games as well.
There are additional items that would aid them with their quests. By collecting 100 coins, the life of the character would be increased by one. By collecting a certain mushroom, the characters will turn larger and these characters would be called Super Mario or Luigi. These characters are able to take two hits before losing one of their lives. There are numerous other "upgrades" available and should only require you to check them out by playing the games. Players would also be playing in different worlds where each world has its own sub-level as well. At the last world and at the last level, they would then fight the last boss and victory would mean the end of the game.
Super Mario also has a lot of versions released by Nintendo. Though the graphic gets slightly better by each of the new version coming out, the game play stays the same. The game might be the one that you play just to kill time. Other than that, it may not be so interesting.
However, there are also car racing games that are starred by characters available in the Mario games. You can find these racing games in arcades. The graphics of it are also much better. You can choose your driver and get upgrades and keep track of them in a card which is available for you to buy on the machine itself. It is very enjoyable to play it with your friends and family members or even just by yourself.
Super Mario games are available in a lot of platform such as the GameBoy Advance, Famicom Disk System, NES and many others. There are also flash game versions of Super Mario available for download. Checkout Mario Games Online for free online games to play.

Wireless Lan's
A Wireless LAN is a wireless local area network that connects two or more computers or devices without using wires. It is commonly called as WLAN.
It was developed by IEEE 802.11(Institute of electrical and electronic engineering). 802.11standards use the
Ethernet protocol and CSMA (carrier sense multiple access with collision avoidance) for path sharing.
WLAN devices allow users to move their laptops from one place to another place within their offices without the need for wires and without losing network connectivity.
WIRELESS LAN’S:
Wireless LAN’s allow greater flexibility and portability than the traditional wired LAN, that the wired LAN requires a wire to connect a user’s computer to a network
But the WLAN connects computer to a network using an access point devices. This access point communicates with devices equipped with wireless network adaptors and it connects to a wired Ethernet LAN. This access point
Devices have a coverage area up to 300 feet (approximately 100 meters).
WIRELESS LAN COMPONENTS:
A Wireless LAN comprises two types of equipments.
1. A wireless station
2. Access point
A wireless stations are equipped with wireless networks interface card (NIC).Access points are base station for the wireless networks, they transmit and receive radio frequency to communicate with wireless devices. Wireless clients can be mobile device such as laptops, personal digital assistants, I phones and fixed devices such as desktops and workstation that are equipped with the wireless network interface (NIC).
Nowadays WLAN are becoming popular in more wide range of business customers.
For example:
Hospitals, Universities, Hotels, retail shops are using this wireless technology to conduct their daily business operations.
BENEFITS:
Wireless LAN’s offer five primary benefits
USER MOBILITY:
Users can access files, network resources and internet without physically connected network to the wires.
RAPID INSTALLATION:
The installation time is very less because the network connection can be made without adding wires, or pulling it through walls or ceiling, or making modification to the infrastructure cable plant.
REDUCED COSTS:
The initial investment of wireless LAN is little higher than the wired LAN, but there is no need of installation charges and the wiring charges.
SCALABILITY:
WLAN network topologies can easily be configured to meet specific application and installation needs and to scale from small peer to peer network to very large enterprise network that enable roaming over a broad area.
FLEXIBILITY:
Users can quickly install a small WLAN for temporary needs such as a conference, tradeshow or in the meetings. It is flexible so we can take WLAN in our necessary locations.
So Wireless LAN’s is best to fit your computers or devices to communicate over a network.

Uses of Bluetooth Remote Control
A Bluetooth remote control can turn a Bluetooth enabled cell phone into a universal remote controller for windows. The Bluetooth remote control enables the user to view his power point slides on his cell phone directly and can play or browse the songs in the Itunes, Media player, WinAm and many more. In other words, a Bluetooth remote control can be called as a true universal remote control which enables the user to modify or add the controlled programs. It also helps to customize simpler key maps or even to gain control over the user interface and write own VB and Java scripts.
Bluetooth remote control can be used for both pleasure and business. A business person can view his power point slides in his cell phone and also can give presentations. Persons using it for pleasure can change the songs that are played on Media player or Itunes, he can also browse for albums and artists and change the volume and so on. The user can also add support to the newer applications. With the use of the key maps the user can define application actions in a very easy manner and can also link them to any of the buttons on the cell phone.
The Bluetooth remote control supports all personal computer Bluetooth solutions. There is no need for setting up a Bluetooth separately as it can be connected from the user’s cell phone. On the whole, the user can view his actual desktop on his cell phone with the help of the Bluetooth remote control.
Since Bluetooth works very efficiently and effectively within the ten meter radius, it can be used for controlling the gadgets of the entire house from anywhere. This makes it possible to switch on or off the television even while lying on the bed in the bedroom without the need to go to the living room and pointing the remote control to the television to turn it on or off. When the Bluetooth technology is combined with the cell phones, it becomes even more powerful, yet very simple and it becomes a real time remote control for the Mac or windows applications.
The Bluetooth remote control allows the user to visually and easily map mouse and keyboard function to the cell phone’s keypad. Any application can be controlled virtually without the need to install any software additionally. The user can even export and import customized control mapping images in order to suit the cell phone model using the favorite graphics package. A HID profile is generated by the application that could be beamed to the Bluetooth remote control using USB/serial, Bluetooth or infrared without even the need for any kind of configuration changes.

Top 5 Influential Games of All Time
I'm sure anyone that has ever owned a video game console or played games on their PC has those few games that they remember most fondly. As the game industry has grown up and evolved so too have the players themselves. The kids who were playing Mario on their NES (Nintendo Entertainment System) and SNES (Super Nintendo Entertainment System) are now spending hundreds of pounds on top end PCs and Xbox 360s.
I'm no different and video games were a huge part of my childhood while growing up. While many people are glued to their TV spending hours watching the same mindless shows I found that games consoles gave a much richer experience. I'm not alone and there are many great games I've played over the years. The following five games are ones that stand out above all others and the ones that changed the way I saw electronic entertainment.
Tetris was the first. As a six year old boy in 1990 I was the proud owner of an original Nintendo GameBoy with Tetris included as the only game. Now obviously as one so young I was never much good at it. I never saw the rocket ship that supposedly appeared if you got a really high score, and I never finished the game. However, what Tetris did do for me was spark an interest in computer games.
Created in 1985 by Alexey Pajitnov the game is one of the most popular and influential of all time. It has appeared in some form on almost every single device capable of running games since it was first released. The version that I played 18 years ago on the GameBoy was one of the most popular and the version that shot it to international success. Tetris is consistently named in the top 5 of 'Greatest Game of All Time' lists, I expect for reasons similar to my own.
There have been many games since that have far eclipsed Tetris in almost every facet but it still remains that first introduction to video games for thousands, maybe millions of people.
Next up is The Legend of Zelda: A Link to the Past. A flagship title for the SNES in the early 90s, A Link to The Past was unlike anything I'd ever played before. Offering two huge worlds to explore and a plot not unlike anything from a Lord of the Rings book it offered more gameplay and replay value than any game I'd played. For the time the graphics and the sounds were amazing and I spent many hours lost in the immersive game world.
The reason I picked this game over it's successor, Ocarina of Time, is that this is the first Zelda game I played, and as such has left a lasting impression. While Ocarina of Time is generally thought of, and rightly so, as being the superior game it was A Link to The Past that really made a huge success of the Zelda franchise.
The next game I chose for this article is one that is actually fairly similar to A Link to The Past. It is made by a Japanese company, features a large explorable game world, a great cast of characters, an engaging story and fantastic gameplay. Final Fantasy 7 was a massive hit. The first of the series to make any impact outside its native Japan the game features one of the best stories ever told in a video game.
This was the first game where I felt that games and film were really starting to merge. FF7 featured many non-interactive cut scenes and FMV (full motion video) sequences to augment the gameplay and help tell the story. While many people are put off by the lengthy pauses in action and hefty amount of text to read I found that the game became like reading a book in which you could decide how the story would unfold and which characters would star, and even if they would live or die.
The success of Final Fantasy 7 led the way for many similar games to get made and flourish in the western market, which typically hadn't warmed to Japanese RPG titles, instead preferring driving and fighting games. It is my belief that even online games such as EverQuest and World of Warcraft would never have enjoyed the level of success they have if it wasn't for FF7.
Usually games based on films are some of the worst games you can play. I don't think I've played a good one before or since my next entry. As important as FF7 was for the Playstation, Goldeneye 007 was so for the N64. A brilliant game that helped bring FPS to consoles and pioneer many features that are simply taken for granted these days.
However the reason I've mentioned Goldeneye isn't for the single player game, nor for the groundbreaking technology. It is for the multiplayer. This was the game that made me realise that as fun as games were, they were far more fun when playing with and against your friends instead of on your own. I lost countless hours of sleep in the late 90s to all-nighter Goldeneye multiplayer sessions with school friends. A brilliant game and the best use of a film license that I can think of.
Last up is a game that brought me back to the PC for games, and one that thanks to its huge modding community has kept me playing for years after its initial release.
Half Life and its sequels and mods that followed were and still are the defining PC games of their generation. The first Half Life game was praised for the complete immersion it offered the player, telling the story entirely through the eyes of Gordon Freeman, without ever taking control from you.
Half Life also had a huge and dedicated modding community. These people created their own single and multiplayer games using the Half Life engine and the SDK released by Valve. Of these mods Counter Strike is by far the most successful and was later released as a commercial product. Counter Strike also happened to be the game that introduced me to games online and on LANs, an extension of the multiplayer gaming enjoyed with Goldeneye on the N64 some years earlier.
Well these were the games that influenced me the most, it is really hard to pick a top 5 and there are many that I've missed. I'm sure that some will agree with the games I've listed and others won't be able to comprehend some of the titles I've left out. Hopefully in the future we'll see some games that will push the boundaries even further and eclipse what we've seen so far.

5 Basic Tips to Selection of Motherboard
Motherboard is one of the important parts of the computer. The entire computing process is based on the motherboard.
The technology of the motherboard are always upgrade frequently in a year. The system is getting more compact and the capacity of the motherboard is get increases. People always love fast speed and they are always in search of higher version of the CPU.
1. System upgaradation includes change in capacity of the processor. The new versions of processors are available from many companies. If you are looking for upgraded version of the processor, you must have to select the processor based on the present system configuration.
2. Apart from the processor, it is essential to select the proper upgraded processor as per your budget. You must have to consult the system engineer to get the suitable version of the processor to replace the current processor. In the earlier years the Celeron mother boards were installed in most of the system and in laptop or notebook.
3. In the present era, Pentium grade and new version of processor are available with higher capacity of the processing the database. Similarly you must have to upgrade the BIOS as per your configurations.
4. If you install the faster processor than it carry more power load and if you install old version of motherboard than it does not work so it is better to select the proper motherboard that suits to your requirement.
5. The motherboard is available around $100 pr more. You must have to select the proper version of the processor based on the motherboard. If you want to install the motherboard you must have to get the details about the capacity of the motherboard that suits to your needs.
It is better to select the motherboard that suits to your existing needs.

What is Bios
One of the most common uses of Flash memory is for the Basic input/output system of your computer, commonly known as the BIOS. On virtually every computer available, the BIOS makes sure all the other chips, hard drives, ports and CPU function together.Every desktop and laptop computer in common use today contains a microprocessor as its central processing unit.
The microprocessor is the hardware component. To get its work done, the microprocessor executes a set of instructions known as software.
Two different types of software:
* The operating system - The operating system provides a set of services for the applications running on your computer, and it also provides the fundamental user interface for your computer.
* The applications - Applications are pieces of software that are programmed to perform specific tasks
* The BIOS are the third type of software your computer needs to operate successfully.
What does BIOS perform?
The BIOS software has a number of different roles, but it’s most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere. It cannot get it from the operating system because the operating system is located on a hard disk, and the microprocessor cannot get to it without some instructions that tell it how. The BIOS provides those instructions.
Some of the other common tasks that the BIOS perform include:
* A power-on self-test (POST) for all of the different hardware components in the system to make sure everything is working properly
* Activating other BIOS chips on different cards installed in the computer - For example, SCSI and graphics cards often have their own BIOS chips.
* Providing a set of low-level routines that the operating system uses to interface to different hardware devices - It is these routines that give the BIOS its name. They manage things like the keyboard, the screen, and the serial and parallel ports, especially when the computer is booting.* Managing a collection of settings for the hard disks, clock, etc.
* The BIOS is special software that interfaces the major hardware components of your computer with the operating system. It is usually stored on a Flash memory chip on the motherboard, but sometimes the chip is another type of ROM.
When you turn on your computer, the BIOS perform many things in the following sequence:
1. Check the CMOS Setup for custom settings
2. Load the interrupt handlers and device drivers
3. Initialize registers and power management
4. Perform the power-on self-test (POST)
5. Display system settings
6. Determine which devices are bootable
7. Initiate the bootstrap sequence
We know that each computer device is prone to some kind of repair. BIOS are not an exception. Computer repair services also include BIOS maintenance services. BIOS when maintained by regular usage of some of the computer repair services results in enhanced computer performance.

External looks are decidedly deceiving when you are standing on the showroom floor looking at the two side by side. Both of the televisions are flat and thin, but they use different engineering to bring you the same results.
How a Plasma TV Works
Plasma TV engineering use the same basic technology as the fluorescent light bulb. The screen is made up of of cells. In each cell two glass panels are set-apart with a thin gap filled with neon-xenon gas and then sealed in the form of plasma when it is produced. This gas is then electrically charged at precise intervals when the Plasma TV is turned on. The electrically charged gas then moves through the red, green, and blue phosphors (A phosphor is any material that, when exposed to radiation, emits visible light ), creating a television Picture. These phosphor cells ( red, green, and blue phosphors) are called pixels.
Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images.
How a LCD TV Works
LCD TVs use a different technology.
panels are made of two sheets of clear material, are then polarized, and glued together. One of the layers is coated with a specific chemical compound that contains the separate liquid crystals. An Electrical charge is then passed through the crystals, allowing the crystals to either let light through or block the light and this creates your image.
LCD crystals do not produce light on their own , so a light source, much like florescent bulb is needed for the LCD to produce a visible picture.
Different from the old style TV or a Plasma TV, there are no phosphors that have to be energized, less power is needed and less heat is generated than a Plasma or old style CRT television. Also, there is no radiation emitted from the LCD screen.
Plasma vs LCD
Plasma over LCD ADVANTAGES:
1. The availability of Larger screens.
2. Deeper blacks for a Better contrast ratio.
3. Clearer color and saturation of the colors.
4. Good motion tracking, very little or no motion lag especially with the faster moving images.
The DISADVANTAGES of Plasma vs LCD are:
1. Plasma TVs are more sensitive to the burn-in effect of static images. It is similar to when you stare at a bright light and then close your eyes and you can still see the light. It goes away but it can be a pain in the butt.
2. Plasma TVs create more heat than LCDs, because of the light needed for the phosphors to create the images.
3. Does not work as well at high altitudes.
4. Shorter screen life span (about 30,000 hours which equals 8 hrs of viewing a day for 9 years). The good news is, screen life span is improving to as high as 60,000 hours because of improvements.
LCD ADVANTAGES over Plasma are:
1. No burn-in effect of static images.
2. Uses less power so it operates at a Cooler temperature.
3. No problems at higher altitudes use.
4. There is an increased image brightness.
5. Longer screen life (about 60,000 hours - Most likely all you will need to do is replace the light source, not the whole thing).
6. Weights less than a Plasma TV so it is easier to mount on a wall.
DISADVANTAGES of LCD vs Plasma televisions include:
1. Less of a contrast, you don't get the deep blacks of a Plasma for that crisp clear picture.
2. Doesn't track motion well (fast moving objects may be a little jittery) - But, this is getting better with the new design of the 120Hz screen refresh rates in top-end LCDs.
3. Hard to find the larger screen sizes. But they are starting to show up on the market at the higher prices.
4. LCD TVs usually cost more than same-sized Plasma TV, However the price of the LCD is coming down due to increased production.
