Lesson 11:Digital Cameras
Like most peripherals, digital cameras are experiencing lower prices, making them more affordable for most consumers. Price ranges and feature sets, though, vary greatly among manufacturers, and non-standard terminology makes it difficult for consumers to select the right product.

Category Overview
Cameras come in a variety of shapes and sizes, with some fairly standard features and some unusual ones. Most come standard with a minimum of 2MB of onboard RAM for image storage, which usually allows about 20 pictures to be stored.

IMAGE STORAGE
Most cameras come with one of the following minimum storage options:2MB of internal RAM, or flash memory; a 2MB or 4MB removable CompactFlash card made by SanDisk, Toshiba's 2MB or 4MB SmartMedia card; or Intel's Miniature card. There are also a few other types, but those listed make up most of the market.
A flash-memory PC card can quickly rewrite blocks of data over and over. Flash memory is non-volatile, which means it retains data without needing a battery backup.
- CompactFlash:Originally developed by SanDisk and now manufactured by other vendors, these storage products are solid state (they have no moving parts) and use roughly 5 percent of the power required by small disk drives.
- Toshiba's SmartMedia is similar in concept to SanDisk's product, but is much smaller, and industry analysts say it is more susceptible to damage due to its light construction.
- Iomega has a format called n-Hand, which is basically a tiny Zip drive that the company has been shopping to camera vendors for about a year. However, due to the power drain the drive mechanism puts on the camera, no company has picked it up.
- Intel's Miniature Card:Competing against CompactFlash technology is Intel's own flavor of memory, the Flash Memory Format. A Miniature Card based on flash memory is also solid state and durable. Like the CompactFlash, Miniature Cards are more affordable than standard PC cards when considering the product's durability and life expectancy.
