Hey!! While think of buying mobile what you consider? Will you ever think of Operating System(OS)? Never!!!! Okay basically we just give importance to mobile appearance and other features like mp3 player, inbuilt and extendible memory. Is it Trendy, slim and sleek. But most of the us are not considering about Operating System OS. It is very important to know about operating system which your phone works. The OS of the mobile phones heavily impacts its performance. The better the OS, the smoother the user experience.

How do you know which is better OS?

Let we see some of the OS and their features, Currently SYMBIAN, WINDOWS, APPLE IPHONE & BLACKBERRY are available in the market.

Symbian – It is developed by Symbian foundation and originally distributed under a proprietary license but, with time, it is drifting towards open source and Eclipse public license. The latest stable version available for symbian OS is v9.4.

Symbian users can enjoy a rich multimedia experience with advanced camera features similar to standalone digital cameras with 35 new features. These include image orientation following tilt sensor, preset image enhancements, digital/optical zoom, auto focus spots, panorama stitch and image distortion correction, auto focus and red eye reduction.

The default user interface (UI) for symbian OS is S60 platform, UIQ, MOAP. User Interface is software platform that runs on top of the symbian OS. It basically contains the user application. With improved seamless connectivity to home computers and the facilitation of easy transfer of music, videos and images, one smartphones can replace several devices.

Content Addressable Memorys (CAM’s) in their most trivial form, work in a way opposite to conventional memories. While a random access memory (RAM) returns data upon providing the address, a CAM provides address when data is supplied. So effectively a CAM is a search tool that looks for the data in question within its data base.

CAM’s commonly work as hardware search engines in routers and switches to accelerate forwarding of packets on the destination route. We will talk about the various other applications that consider a CAM as an important processing engine as we proceed engine as we proceed in this article.

As indicated in its definition, CAM holds the address to be looked up for and returns the route associated information to the host processor to perform the successive tasks of forwarding the incoming packet. So we can also define a CAM as a network coprocessor to the central processor.

Note that TCP/IP and /or OSI models are taken here as reference to explain the concepts similar analogies may be drawn with other protocols like IPX/SPX, Apple Talk and UDP.

In order to get a true understanding of the functionality of CAM’s, you need to dig a little deeper into the domain in which these work. If you look at either the OSI reference model or the TCP/IP stack, you will find that the lower three layers are the ones that are concerned with the packet delivery to its peer, while all the other layers are more concerned with the content, its presentation and formatting.

The physical layer adopts analogue means of data transfer and is not concerned with acknowledgement of the transmitted data. This leaves the next two layers to make sure that the transmitted packet was indeed received in its original form – that is the order of information, encryption used for data protection, etc

Another important task that needs to be performed by these upper layers is to ensure delivery of the packet to its correct recipient. This is done in two ways.

1. Using MAC (media access control) address. This addressing scheme is adopted at layer 2 of the OSI layer. It is used in such network device as switches/bridges.

2. Using IP addresses. This addressing scheme is used to transmit any IP packet and communicate with its peer on the network, which is the data link layer on the destination. It is used in such network devices as routers and layer 3 switches.

One of the confusing things in choosing a digital camera is deciding how many mega-pixels you should look for. The answer depends on what you plan on doing with the finished pictures.

First, you need to understand what a pixel is. In terms of digital prints, a pixel simply means a dot of color that makes up the image. A mega-pixel is equal to one million pixels. The more mega-pixels a camera has, the greater the amount of information it records.

The easiest way to decide what to look for is to know what size prints you are likely to print from your camera. A one mega-pixel camera is fine for those who don’t plan on printing photos but rather just post them on the internet. A small print, say 4 x 6, will print acceptably from this camera.

A 2 mega-pixel camera will enable you to produce good quality 5 x 7 prints and fair quality 8 x 10 prints. When you reach 4 mega-pixels you can print out excellent quality 8 x 10 prints and acceptable 11 x 17 prints and a 5 mega pixel camera will allow you to print out high quality 11 x 17 prints.

Most families find a camera in the 3.2 Mega-pixel range to be the best choice. The quality of both 5 x & and 8 X 10 prints is very good yet the files on your computer are not so large you need worry about not having enough space.

Any camera over 5 mega-pixels is unnecessary for all but professionals in photography; even then, only those who have need for poster-size prints find that many mega-pixels worth the money. Most freelance photographers find 4 or 5 mega-pixels to be sufficient for excellent-quality prints.

The choice is yours. Look to what you plan on doing with your photos and then decide. In most cases spending the money for increased optical zoom and lower mega-pixels is the best choice.

With all the features digital cameras have these days, you may find keeping batteries a problem. This could well be your biggest expense, but there are some things you can do to increase the length of time your batteries stay charged. Let’s start with the three biggest sources of power drain.
The LCD screen takes up the most power. It is possible to turn this feature off unless you really feel the need for it. Using the camera’s viewfinder will conserve power. Another big power drain is the flash. Whenever you can, use natural lighting to take your photos and turn off the flash. This will help save your battery for times when you absolutely need the flash. A third drain on your battery is constantly using your zoom. It takes more power zooming in and out than it does keeping your zoom at a steady place. Try to find a setting you like and sticking with it as much as possible..
Some other things you can do to make your battery last longer are::
* Make sure Power Saving mode is on, or simply switch off your camera when you’re not using it.
*In cold weather, keep your camera and batteries warm in your jacket until you are ready to use them. The cold drains batteries very quickly.
*Store batteries in a cool, dry location away from sunlight and other heat sources.
*Avoid unnecessary playback of your already taken images. Try to decide when you take the picture if it is a “keeper” or needs deleted and then refrain from reviewing until the pictures are downloaded to your computer.
*Use the AC adapter. Most digital cameras have an adapter that allows you to plug directly into a power point. If you don’t plan on moving around a lot and are near an outlet, the AC adapter will increase the life of your batteries.

Needing to buy more or recharge your battery is something you won’t be able to avoid completely, but with a few precautions this won’t be needed as often.
