A portable device, designed by Apple computer, used for storing and playing audio files, is termed as the iPod. These devices have their own distinctive style and can store anything from a few hundred to a few thousand songs. All these audio files are generally encoded from MP3 and Advanced Audio Coding (AAC) compression algorithms.

The iPod was released by Apple in 2001 and till date no other device has been able to match the ease of use of it. A couple of years later, the same manufacturers also designed and released the mini iPods that were one-third of the size of the original. Then, came the shuffle, the smallest member of the iPod family, which was almost the size of the package of a stick gum.

Initially the they had a small hard disk for storage. Even the flash memory used by shuffle had a small hard disk. The only benefit with the flash memory is that it retains its contents even after the power is turned off, unlike the computer memory that loses its content once the power is switched off. But with increasing downfall in the capacity as well as the prices of all the three models, the storage capacity of all the three has increased over time.

The greatest advantage of the iPods is the way it works with the programs on the PC. They work in synchronization with a software called iTunes present in the personal computer (PC). This happens as soon as it is connected with the PC that uses either Windows or Macintosh operating systems. It automatically updates the music library and keeps a track of how often a song is played. It removes the old episodes that are heard and replaces it with the new ones. This synchronization does not require the intervention of the user and this has made the iPods much more accessible than the MP3s and has resulted in its domination over the other devices.

Another advantage of iPod is that, the moment they are plugged in, the batteries recharge, without any manual botheration. Moreover they work quite well as audiobooks. This is especially noted when you stop listening, it remembers exactly the song where you stopped and begins automatically from the next one. This facility is generally not available on most of the players where it is required to listen to the entire chapter to get to the next number. Also, we get the facility of listening to songs at a faster rate that proves helpful when there is enough material to cover in a short time.

The Apple added another feather to its cap in the form of the iPhone, which is a blend of the cell phone and iPod in one device. This portable device also has a camera and can even connect to the internet, that too wirelessly. Thus a small box can be used for making phone calls, listening to music, taking pictures, downloading music, checking e-mails and surfing websites. After the iPhone, came the iPod touch that resembles the former a lot in appearance and functions except for the camera and the phone.

However, before buying any model of iPod, it is important to consider the use of the same. If you want to watch videos or play games, then the earlier versions can be a good choice. Shuffles and nano are simply wrong choices for such an application. These models are functional if you are just interested in hearing a lot of music of your choice. The iPhones and iPod touch are multifunctional and the latest choice of the present generation.

iPods have also faced some criticism based on its short life span and frail hard drives. Moreover they were condemned over the fact that some of their models were more durable than the others. It was observed that the models that used hard drives were weaker than the models using flash memory. Inspite of all these downs, iPod continued its innovativeness and won many accolades and awards throughout the world.

Car stereos are installed in cars to make the driving comfortable and enjoyable. For most of the people today a car stereo is a vital element of their car. They are placed at the heart of the car audio system and are nicely shaped and fitted as to match the interiors of the car.

Now, it may sometimes happen that rather than using the factory installed car stereo year after year, people may want to try a better quality system. But lack of knowledge about the specific ways of removing an installed car stereo can prove to be a hindrance. However, in this case it should be mentioned that though removing an installed car stereo is not a tough job yet it needs caution since the process is technical.

The process of removing an installed car stereo depends mainly on the type of the stereo and the type of the car. Generally, there are two main ways to remove a car stereo, the spring mounted clips and bolt-on. In the first, the stereo is held in place by 4 small clips, so that the stereo does not slide out of the dash. The tools necessary to remove it are a pair of DIN tools that are usually U-shaped. And at the top of the U there are small poles that fix the clips to the stereo. After inserting properly, there will be a click sound and the stereo will simply slide out of the dash.

There are car stereos that are attached to the dash and then it will be a bit difficult to get it out. However, there aren’t special tools for the uninstalling process. There are brackets bolted to the car. They are sometimes mounted to the stereo to bring some variation in the method. However, to access the screws or the bolts that hold the stereo in the place, a few trims have to be removed. And one has to be careful while removing them. That is the essence of the bolt-on method.

There are basically one or two trim pieces that surround the face of the stereo. And to remove it the screws that are usually hidden from normal view have to be detached. Infact, there are some hidden clips which have to be taken care of while removing the trim. In this case, removal tools can be used.

Now once the trims are removed we should remove the screws or bolts holding it in place. When they too are removed, the stereo will slide out of the dash.

Then you should disconnect the electrical connectors at the back of the stereo, by unscrewing the antenna cable at first. Actually, the antenna cable is the furthest connection near the passenger side. The next step is removing the power connection. Finally, you must remove the wiring harness connector from the back of the stereo. Now, as all the electrical connections are removed from the back of the stereo, the car stereo is removed completely. These are basic instructions about removing an installed car stereo. In the case of any complication you should give a call to the service center and get expert guidance.

A photographic camera is an apparatus for taking photographs or moving film. All cameras have the same basic design - a lightproof container with a lens and a light-sensitive surface. A digital camera is different from a standard 35 mm SLR (single lens reflex) in the sense that digital cameras require no film rolls.

In earlier times careful planning went into taking pictures of an object but with a digital camera you can take a number of photographs and then select the best posture that you have captured while the rest of the pictures can always be deleted without involving any monetary loss. The pictures can then be transferred to your personal computer from where you can take out printouts if you have a color printer installed.

The quality of the photographs in a digital camera depends upon the camera resolution which is determined by pixels. Pixels or picture elements are any of the minute areas of uniform illumination of which an image on a digital display screen is composed. The greater the number of these pixels, the sharper is the image created. A digital camera which offers a resolution of 5 mega pixels is normally considered a good camera.

The weight of the digital camera also goes a long way in camera selection. Once upon a time digital cameras used to weigh one kilogram but with technological advancement they have become very compact and sleek. These modern cameras now come with zoom facilities. You can use digital zoom in any picture-taking mode to get up to 3X magnification beyond optical zoom.

You can do more with your digital camera like using different modes. General picture taking offers an excellent balance of image quality and ease of use. Point-and-shoot simplicity function is provided when taking pictures under special conditions. You can capture video with sound. You can view your favorite pictures. To capture far away scenes, the camera uses infinity auto focus. The camera automatically sets the focus distance depending on the zoom position.

Most digital cameras permit a white-balance setting which automatically transmits by inference which element should look white and which should look black. The lens is an integral part of any camera and determines the quality of the photographs. All digital cameras have LCD screens which can vary in size.

Care and maintenance of your digital camera is of utmost importance. If you suspect water has gotten inside the camera, remove the battery and memory card and allow all components to air-dry for at least 24 hours before using the camera. Blow lightly on the lens or LCD to get rid of dirt and dust. You should always wipe softly with a lint-free and soft cloth or lens cleaning tissue. Never use solutions unless intended particularly for camera lenses. Never allow chemicals such as sun tan lotion, to contact painted surfaces.

For digital camera, battery care is vital. Do not allow batteries to touch metal objects, including coins. Otherwise a battery may short circuit, discharge energy, become hot or leak. Always remove the battery when the product is stored for an extended period of time.

If your budget allows always buy a digital camera that provides you with higher resolutions, longer zoom lens and some other special features. Advanced consumer cameras usually require that you spend some time with the instruction manual to master all their capabilities, but they have few limitations.

Digital camera assures a user friendly working with pictures and videos. If accidentally you delete a picture you can use the undo delete function to retrieve it but this should be done immediately after you delete a single picture.

The walkie talkie, also known as the handheld transceiver has a rich history and has been instrumental in developments in the military sphere. Fundamentally they are a hand held way to communicate with anyone else who has a similar device. Their history can be traced to the Canadian government who during the Second World War designed the device in order that military operatives had a ready form of communication for operational activities.

The first walkie talkie device was the Motorola SCR-300. First being released in 1940 it was not as handheld as modern variants; at this time the smallest devices still required the user to carry a backpack. However development occurred quickly and in the latter stages of the war a handheld device was released being labelled the ‘handie talkie’ by troops. The term walkie talkie, although being used describe all modern devices during the war referred to the backpack model rather than the handheld. The handie variety however suffered in terms of operation because of its reduced size.

Development after the war was rapid with improvements to both range and size evident amongst the allied nations. However the walkie talkie still had its limitations. Due to the power restrictions, normally only a few watts, the communication applications were somewhat poor. Most handheld devices of the post war era, even up to the seventies operated poorly in built up areas where buildings restricted the transmission of radio waves. As a result, military personnel often had to utilise a highly mounted ‘repeater’ that vastly improved the range of the device.

Today the walkie talkie is still a frequently used device in the military although modern models are far smaller and usually integrated in the form of headsets and mouthpieces. The devices however are not purely used in the military sphere, applications today include the public sector, outdoor activities and security personnel, in fact anywhere where constant communication is needed, a walkie talkie is regarded a standard piece of equipment. Other developments have improved the durability of the devices making them shockproof and waterproof. Some developments have focussed on the size of the devices; modern electronics have allowed light and small models to enter the market. Additionally, designers have incorporated scrambling devices in order for operatives to have private communications; this type of development has been especially useful in the construction of police radios.

The walkie talkie has also become a popular toy for children. Predominantly these are low power devices that do not require a licence because they operate in a specific frequency range and do not have the power to communicate over long distances. Normally the components used in the construction of these toys are far cheaper than ‘adult’ varieties meaning that they are not applicable for uses in business. In addition, while more expensive models have a separate microphone and speaker, the children’s models use one speaker for both purposes. One use that is not normally present on adult variants is the inclusion of a code button on kid’s devices. While this is included for the use of Morse code messaging, it is usually used to annoy parents.

The walkie talkie has come from a military background, created to ease the tasks of those in warfare to a device that can be used by children as a toy. This shows that it has entered many different sections of society and has become integral to many different communication requirements. Without the invention of this device, short range communication would not be as easy; the role they play in security, law enforcement and safety procedures cannot be underestimated and most probably form the most important developments the walkie talkie has brought us.

Technology expert Thomas Pretty looks into the history of the walkie talkie and its various uses in military, public sector and entertainment spheres.

Deciding on which game console is the best depends on the user. Technology wise all the three game console utilizes the state of the art technology. It would be harder to determine which one is better in the sense that all of them give a different kind of excitement to its clients.

Especially the game console Wii because how the game is played is different than what you used to. It allows movements of your hands in order to execute actions from your characters. Using the game Wii is ideal when you play sports like boxing, tennis, and bowling. The downside of having this game console is that it would be hard to play strategy games using this kind of game play. It is kind of complex and difficult to get used to when you play first person shooter. Changing weapons and reloading and browsing through the menus is hard enough, how much more if you are running and trying to focus to shoot a target. The good thing about this kind of game console is that it allows you to practically be part of the game itself. It is as if you are really the one playing it. This would provide their users a different sense of enjoyment unlike the usual game console that you are used to.

Playstation3 is certainly the most user friendly among the three game consoles because most gamers are already familiar of its game menus and most of all the games that you could playing using the game console is almost limitless. Being the first among the three game consoles do have its benefits because most games available can be played available could be played on PS3. There are no limitations in whatever games you wanted to play if you have this game console around. The graphics is also good and not to be taken lightly. However, the problem of PS3 is that you could not store enough games in your console because the memory slots are limited. You are also limited in playing in two players which is not the ideal way of playing when you are in a group.

The Xbox is probably one of the newest game consoles that allow you to store more games in your system. It has a higher memory capacity compared to its counterparts. The best thing about this game console is that you can play more than two players at the same time. Now that is something new and exciting. Its graphics is also commendable. The downside of playing this game console is that you can play only limited games in it. Unlike the Playstation3 that allows its players to play almost any game out in the market.

Choosing the right one that suits your needs depends on your taste. Some people like playing Playstation3 while others prefer Xbox. Some prefer a new way of doing games and they eventually chose the Wii. The three game consoles that I mentioned have their own advantages and disadvantages. Make sure to check its pros and cons before playing it.
