Shutter Speed

Shutter speed is nothing but the amount of time that the shutter is kept open or the length of time that your image sensor looks at the scene you’re attempting to capture. Shutter speed is measured in fractions of seconds. In most cases you’ll probably be using shutter speeds of 1/60th of a second or faster. The bigger the denominator the faster the speed (Example: 1/500 is much faster than 1/8). Lower shutter speed will lead to blur images because of camera shake. Camera shake is when your camera is moving while the shutter is open. Use tripod or image stabilization cameras when working with low shutter speed. Different selection of shutter speeds will yield different kind of visual effect on a final photograph. Generally, a fast shutter speed can freeze action while slow speed can blur your image. I would say keep experimenting the same shot with different settings to learn more.

Canon's AI Servo

AI Servo is Canon's predictive autofocus (AF) system. The name is derived from the use of Artificial Intelligence used to predict the speed and distance of the moving subject. It greatly increases your chance of getting a sharp image when your target is moving. It is the camera's ability to continuously focus on a moving subject, a feature normally only found on digital SLRs. It is generally used by sports or wildlife photographers to keep a moving subject in focus.
Autofocus Servo is normally engaged by switching focus mode to "AI Servo" in Canon or "Continuous" in Nikon followed by half-pressing the shutter release. The camera will continue to focus based on its own focus rules and your settings while the shutter release is half-pressed or fully depressed (actually taking shots). Predictive autofocusing happens whenever AI Servo is on and there's a readable subject with predictable movement where as Shutter release timing is controlled by the photographer for single shots and the first shot in a burst.

Choosing a branded Camera ?

Buying a digital camera can be disorienting. There are hundreds of cameras available at many different types of retail outlets, with prices ranging from $75 (Rs. 3500) to several thousand dollars. This, of course, is the big question that you really want an answer to and you know that nobody is going to give you one. If you ask anyone who already has a camera most will support the brand of the camera they have unless they have had some trouble with it, even then people are very forgiving. Also, be careful about fake cameras. You think you  paid for a popular brand until you reach home, tear the product box, and notice a slight variation in the spelling of  manufacturer' name. You feel cheated but often it's too late to do anything about it. Digital cameras are expensive electronics items, you don't want to get the brand wrong. I am a fan of Canon as they are into this business for a long time and my opinion about manufacturers who make the best film cameras would be Canon, Nikon, and Olympus, seem to make the best digital cameras. There are many other brands like Kodak, Panasonic, Fujifilm, Sony, Samsung etc.

Megapixel

Megapixel, one million pixels, refers to the number of dots in a digital cameras and other digital displays. The megapixel measurement reflects the ratio of individual pixels in a screen as it is divided by one million. In simple terms, a megapixel tells a photographer the camera’s capacity to detail an image. Digital cameras tend to produce images at 2048 x 1536 pixels, which renders a 3.1 megapixel measurement. The higher the megapixel number, the greater the resolution of the digital image. Images with higher resolutions appear clearer, sharper and more vivid.
