Few Facts Of Digital Cameras
A digital camera captures images in a digital format, unlike a conventional camera, which captures images using a photographic film.
History:
Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be produced in a digital domain. An engineer at Eastman Kodak, Steve Sasson, used solid-state CCD chips to build a prototype digital camera having a resolution of 0.01 megapixel, and recorded black and white digital images to a magnetic cassette tape. With this prototype model, Steve took the first image in December of 1975 taking 23 seconds to capture it.
In 1988, Fuji DS-1P became the first digital camera that captured images as a computerized file. However, the camera never entered the U.S. market. In 1991, Kodak DCS-100 was the first commercially available digital camera, which used a 1.3 megapixel sensor. With the advancement of technology, modern digital cameras have become multifunctional and are now capable of capturing audio/video and still photographs.
Benefits:
1 - You get superior image quality. Digital cameras can offer good to excellent image resolution.
2 - You get a fair price. A digital camera is reasonably priced and is affordable.
3 - You can transfer the pictures to your laptop. You can easily connect the digital camera to your laptop and transfer the pictures in your hard disk.
4 - You can print in large sizes. Due to its high resolution, pictures can be printed in large sizes by any plotter.
5 - You can email the pictures to your friends. You can send the pictures by email to your loved ones.
6 - You can store the images in CDs or hard disk. Once the pictures are transferred from digital camera to the computer, permanent storage on a CD or hard disk is possible.
7 - You can take the camera in your pocket while you travel. The small size of the digital camera makes traveling with it easy and a pleasure.
8 - You can move in close to your subject. Zoom lenses offer close-ups of your subject with sharp focus. You can take very good close-ups of flowers, bugs, stamps, coins, etc.
9 - You can rework the image in a computer. Any photo editing software can rework the images taken.
10 - You can take good pictures even in low-light situations. Due to flexible over sensitivity or ISO equivalents, digital cameras can easily take detailed pictures even in low-light conditions.
11 - You can take quality still photos of moving objects. Sports and fashion photography can be easily accomplished due to the fast burst rate of digital cameras.
12 - You save money. There is no need of buying photographic films, developing them into negatives and positives. Moreover, the batteries are usually rechargeable lithium-ion batteries, which last a long time.
13 - You can choose as per your needs and fancy. Many models are available like standard digital camera, underwater digital camera, waterproof digital camera, compact digital camera, and the professional digital camera.
Storage Media:
Digital cameras use memory to capture and store images. Some of the storages media used are onboard flash memory, 3.5" floppy disks, video floppy disk, PCMCIA hard drives, CD or DVD, CompactFlash memory cards, Microdrives, Memory Stick, SD/MMC, MiniSD Card, MicroSD Card, XD-Picture Card, SmartMedia, and FP Memory.
Power:
Digital cameras consume a lot of power, which is supplied by powerful, small in size batteries. Batteries are broadly divided into two groups, namely, off-the-shelf and proprietary. Off-the-shelf batteries are like AA, CR2, CR-V3, AAA, and RCR-V3. They are lithium-ion (Li-Ion) or Nickel metal hydride (NiMH) batteries. Standard AA non-rechargeable alkaline batteries either do not work or work for only a very short time in most cameras.
Proprietary batteries are built as per the manufacturer`s custom specifications and are usually available as aftermarket replacement parts. Generally, lithium ion batteries are widely used as proprietary batteries for digital cameras.

CECT I9 Review – How Does This New Quad Band With Java, More Memory, and Dual Sim Active Stack Up?
For almost a year, the original iPhone clone, the CECT P168, was known pretty much as the premier, best selling clone. I think this is because it was the closest thing to the original, very user friendly, had several embraced bonus features, and was widely available for not much money. That trend has changed though as the manufacturers have been rolling out improvements and upgrades to this well received model. One of the best selling of these newer models is the CECT i9. This article will review it's features, performance, and price.
Standard Popular Features: The i9 phone has everything the previous clones had and more. It is often thought of as "the best of both worlds" among the clones because it combines the standard popular features of many of the mainstream models with a few of the novelty features that are also gaining ground. As with most all of the clones, this one allows: web browsing; texting and email; full SMS, MMS, and WAP capabilities; MP3/MP4; Bluetooth; a built in digital camera / web cam and an FM radio. So, this is where this phone is the same, but here is where it is different.
Dual Sim Active: Like most of the clones, this one allows you to have two phone numbers or networks on one phone. However, unlike most - many of these phones sold under the name i9 allow for both sim cards to be active and online at once without needing to switch back and forth between the two.
Shake And Tilt Control AKA Swing To The Music: The original P168 did not have this addition. It came later on models like the A88 and the A380i. This means that you can advance music, media, wall papers, etc. by only shaking the phone. You don't have to look down or scroll. Likewise, the images on the phone will always right themselves no matter which way you turn or tilt the phone. Images go from portrait to landscape depending on which way you are holding or turning it.
Java: If there was any drawback to the original clones, it was that you could not download third party software or games via Java. This one supports Java so this is no longer an issue. Software like MSN, PowerPoint, Excel, and Outlook Express gives this cell phone so many more productivity and gaming possibilities.
Smaller, Sleeker Size: The i9 is smaller and sleeker than previous models, is dwarfed by a dollar bill, and will easily fit into a small pocket. It weighs only 95 grams with the dimensions of 110 x 60 x 11.5 mm.
More Memory: The original clones were expandable to up to 2GB of memory. The 9 can hold up to 8GB of memory (although it's more common to see them with 4GB). This is huge in my opinion because it ensures the phone is fast to function and download and you don't have to worry about it getting bogged down when you download songs, video and information.
Quad Band: The original iClone was a tri band. This one is a quad band, which covers nearly all world wide GSM networks.
Performance: I really like this phone. It performs very well and feels like a solid, high quality gadget. Since it now has Java, dual sim active, and more memory, it covers almost everything you could want in a phone. The slightly size does make it a bit slower to compose txt documents if you have large fingers, but I still prefer a lighter weight, sleeker model and feel this is a fair trade off. I've not found any bugs with it and I also like that it includes shake and tilt. I know that some people see this feature as a little eccentric (you either love it or hate it) but I am one of those people who finds it pretty useful.
Pricing: This CECT smart phone averages around $150, depending on how much memory is included. This is a bit more than some of the older models, obviously, but with all of the upgrades, I feel that it is more than worth it.
The Most Common Laptop Battery Problems
Laptop batteries can often be expensive because the laptop manufacturer is the only one who makes a battery to fit their particular laptop. This is done so the manufacturer will have control of the market when you need a new battery. Often this is done to encourage you to buy a new laptop instead of replacing the battery. In many cases there is little difference in the price, which is what the manufacturer intended.
Some laptop batteries, such as the Ni-Cad, will suffer from a problem which is commonly called the memory effect. This is caused when you continually recharge the battery without letting it discharge entirely. After a time the battery will forget that it has unused capacity and it will discharge much faster each time it is used. The best way to avoid this laptop battery problem is to allow your battery to completely discharge at least once each month. This allows the battery to retain its original memory and provides longer usage.
When your laptop is not in use for an extended period of time it is best to remove the battery. The battery will continue to slowly discharge during the time it is not in use. If this discharge takes place inside the laptop you may not be able to get your laptop to recognize the battery the next time it is recharged.
You can also experience battery problems if you allow your battery to completely discharge outside the laptop. You should check the battery while it in storage so it will not be allowed to completely discharge. This could also prevent the laptop from accepting the battery when you place it back into the computer.
If your laptop battery becomes hot to the touch you will need to remove the battery and allow it to cool off. If this problem continues when you replace the battery in the laptop, you will probably have a defective battery. It is best to remove the battery and replace it since a defective battery could cause extensive damage to the laptop.
Temperatures have an effect on laptop batteries. If you are experiencing extremely hot temperatures you will need to keep the battery in as cool an area as possible. Extreme heat can cause the battery to discharge prematurely and can eventually lead to battery damage.
Last year Toshiba recalled about 430,000 laptop batteries because they continued to lose power prematurely. Toshiba also reports that although these batteries were giving problems by losing power, there were no reports of the batteries overheating and there were no reported injuries as a result of the defective batteries.
Before the Toshiba recall, Dell and Apple had a battery recall because Sony had produced a defective batch of batteries. These batteries were known to overheat and some of them even produced fires. All of these batteries were replaced free of charge but the company did suffer some financial damage as a result of the recall.
Panasonic also had a laptop battery recall because the latches were defective. This was causing a mechanical problem with the batteries because they were not properly latched in. In many cases these batteries overheated but there were not reported injuries.
Laptops – Leading With Innovation
Latest gadgets such as laptops are proving to be useful in different spheres. From busy executives and software professionals to college-going students and busy housewives - people in different areas of work are realizing the benefits of state-of-the-art technology for staying connected on the move. As a natural corollary to this trend, the demand for innovative laptops is on the increase. Leading notebook manufacturers are taking a cue from these trends in customer behavior; they are designing and developing the most sophisticated laptops to satisfy this increasing demand for the same.
The Protege R400 notebook computer can be cited as a case in point. This mobile computing solution brings the knowledge of two leading manufacturers - Toshiba and Microsoft to users. This very high-end laptop is expected to meet the advanced needs of users, very much into mobile computing.The point that can be derived from this example is that the leading industry giants are realizing the huge possibilities that can be explored in this area. Consequently, they are associating with one another to create signature products wherein equal emphasis is given on style and ergonomics. The customers are the ultimate beneficiaries of these efforts. They get to possess and use some of the most sleek looking and sophisticated gadgets, such as laptops and that too at the most industry leading costs.
It can be concluded from this discussion that quite a lot goes into the design and development of the latest gadgets such as mobile phones or laptops. The best brains from different fields are coming together to give an out-of-the-world experience to customers and clients. In all these efforts, the focus is on innovation; the process of innovation is guided by what the customers want. And the end-product is often very much up to customer expectations. Users are in fact, more than happy with the latest laptops and notebooks that are currently available in the market.
What is Computer Desktop Remote Computer Access?
You are due to give a presentation at work on Monday - you have worked all weekend on perfecting it and when you reach office you find to your horror that you forgot to update the file on your USB drive. If you have ever found yourself in a similar situation, you might have wished very hard for access to your computer at home for just a short while to transfer the file.
This is exactly the function performed by Remote Computer Access - it helps you to use a computer to connect to another computer over the Internet for file access and for getting information even when the computers are separated by several miles.
There are two ways of achieving this - one is to use the Shared file system provided by Windows and the other is to use commercial software with a proprietary system. Remote access need not be confined to file access alone; you can also control the desktop of a computer that has been configured for remote access.
Once your computer has been configured for remote access, you can sit in front of a computer anywhere in the world and use the Internet to work on your computer - of course, the main drawback will be the delay in the response from your computer which would be a function of the distance separating you and your computer and the network speed. Drawbacks aside, the flexibility provided by remote access is enormous and eliminates the need to synchronize files on two different computers.
The level of access provided by remote access depends on the operating systems used on the client machine and the remote computer. If you are using Windows XP on both, the task is simplified as Windows XP comes with inbuilt support for remote access. You can log in to the remote machine using the same credentials you would use while sitting in front of it. Remote access is also secure.
With the remote desktop enabled, you can run programs on the remote computer, edit, save and transfer files between the two systems. Be aware that file transfer may be slow. You can print out documents from the remote computer on the printer connected to the computer where you are working and also hear audio played on the remote computer.
Setting up the remote desktop under Windows XP is simple and access can be initiated by selecting Start->programs->accessories->communications->remote desktop connection. Just type in the IP address of the remote computer in the window that pops up and click on Connect. You can now access the remote desktop. Once you are done, you can log-off from the remote computer to terminate the session.
