what the diffrent of digital zoom and opital zoom?

They are both done optically, it is just how it is processed that is different.  By that I mean one is on film and the other is stored digitally, however it is still the movement of the lens that increases or decreases power of the image for the picture.

commmon one is Convex lens\n(with different angles, to magnify upto diff levels)\nbut for higher levels, it depends upto the magnifying object and distance also

Most of the information in this guide applies to all video cameras whether they are digital or analog. Analog is the term used for all older style video cameras, recorders and players. The main feature of analog representations is that they are continuous. Digital representations consist of values measured at discrete intervals. These intervals can be so short as to simulate continuous movement.\n~~~Logigly  video images comes from a tape or memory card~~~\n~~~if you wish to understand the difference between Analog and digital video you must first understand the diference between those who created them (CAMERS) the difference between a digital and a analog camera~~~\nForm more documentetion Just CLick the link below:

I think you have that backwards.  Monitors have historically been analog (VGA), but more and more are now becoming available with digital inputs (DVI).\n\nDigital offers many benefits over analog, including longer cable lengths and a superior picture, but suffers (currently) from extra expense.  However the price gap is constantly decreasing, and before long analog monitors will become as much a historical curiosity as black-and-white TV.\n\nThe main reason for the improved clarity is that a digital interface allows your video card to directly address each and every pixel on your monitor individually.  No longer does the monitor have to approximate the desired result; the card can tell it precisely what needs to be displayed on every discrete pixel.\n\nIf you get a chance to try a dual-input monitor on a dual-output PC, you'll be amazed at just how much sharper the digital image is when you switch between the two sources.

Tabbed browsing, pop-up suppression, and better support for HTML, Javascript, and CSS standards, for starters. It's also a little faster.\n\nOne big difference is the lack of Active X support. While this means you still have to use IE to update Windows, the upside is that it eliminates some of the nastier ways in which a malicious website can manipulate your computer.

Have you tried maps.google.com?  It's quite brilliant and can give you a map, satellite shot, or a hybrid view of both.  The only iffy part will be how far it will let you zoom in.  But give it a try.

Adding to the above... If you can afford it and you want more than about 7x magnification, you should consider buying IS (image stabilizing) binoculars.   These need batteries, but dynamically correct for the shaking of your hands.  You can get them up to 15x magnification.\n\nAlso, it's important to consider what you want to use the binoculars for.  If you're going to use them at comparatively short distances, you don't want a pair that magnify too much because you'll have to keep moving the glasses around to see entire objects.  (That's why opera glasses, which are a form of binocular, are such low magnification - typically 2-4x).   Also, if you plan to use them at night or in low light, you want a large objective lens size (50mm or larger) because that allows the glasses to gather more light.\n\nLastly, if you'll use them in unstable situations (like a moving boat), consider the size of the exit pupil.  This is the objective diameter divided by the magnification, and measures the diameter of the image which your eye looks at.   This is important because it affects how precisely your eye has to be lined up with the eyepiece for you to see the image.

The DVI is a purely raw signal. While HDTV is a clean up of the signal and progressive scan is for skips. There is also the fact of how big your T.V. is compared to you monitor. It might look better because it's smaller, so there is less pixel space to cover.

1.- Optical mice are very sensitive to the material upon which they sit: make sure you are using an optical mousepad or other surface that is optical friendly \n\n2.- You might also want to check the sensitivity that you have selected for your mouse in the Windows XP Control Panel area. Choose Start -> Control Panel -> Mouse then go to the Pointer Options tab and see if any of those settings affect the behavior you're seeing.

Depends..\n\nIf you're wanting to get new photos on the computer, then a digital camera is the choice.\n\nIf you're want to empty the photo albums and get them digitized, then you need a scanner.\n\nAnd if you want to do both and you're on a tight budget, buy a $100 Scanner and spend a couple hundred on a digital camera.  And you'll have a good mix.

a regular camera lens focuses in light sensitive diodes, then the diodes changes electricity into digital elericity which is  0s and 1s which can be a file on a computer, and then those can focus on the computer into a folder

I am gessing that you want to knoe about "optical" telescope.\n\nThere are basically two types of optical telescopes.\n\n1. Refrective Telescope\n==========================\n\nThere is an objective lense that creates a virtual image of the object you are trying to see very close to asecond lense called the eaypiece. The eyepiece magnifies that virtual image many times bigger.\n\nMagnification = focal length of objective/focal lenth of eyepiece\n\n2. Mirror type (Newtonian)\n==========================\n\nThis type uses a parabolic mirror to create a virtual image of the object you are trying to see very close to the eaypiece. The eyepiece magnifies that virtual image many times bigger.\n\nMagnification = focal length of mirror/focal lenth of eyepiece

It might be appropriate to use one on a page that zooms a map, but probably not on a regular menu bar.  Think about the rest yourself and the amount of resources it consumes.  Also if there are other ways to accomplish the same clearly with less resources.  Hope this will help.

ImageZoom: you can enlarge photos by holding down the right mouse button and scrolling up or down.\n\nFlashBlock: automatically blocks all the flash on a site and replaces it with a clickable button.\n\nTabPreview: opens up a thumbnail of a tab when cursor is hovered over it.

magnification: is like how u see things pretty when they're away "distant " from you and when they come closer you see how much things u weren't able to see before.\nResolution: is like that when u have more knowledge about something and when u face it u could go along with it till a certain limit where ur knowledge limit.

.tiff is used for huge ultra-detailed images like full-sized astronomy pics from telescopes and such\n\n.gif is good for images with few colors and for animation\n\n.bmp is for non-compressed images (so watch out how big and how many colors there are or it'll be quite large)\n\n.png is good for images with a lot or few colors\n\n.jpg is good for compressed photo-quality images, but it can cause a lot of distortion
