CD Short for
"Compact Disc," A CD-ROM can be read by a computer with an optical drive. The "ROM"
part of the term means the data on the disc is "read-only," or cannot altered or
erased. Because of this feature and their large capacity, CD-ROMs are a great media
format for retail software. CD-ROMs share the same technology as audio CDs, but
they are formatted differently, allowing them to store many types of data.

DVD (also
known as "Digital Versatile Disc" or "Digital Video Disc") is a popular optical
disc storage media format. Its main uses are video and data storage. Most DVDs are
of the same dimensions as compact discs (CDs) but store more than seven times as
much data.

SD Memory Card
Stands for "Secure Digital." It is a type of memory card used for storing data in
devices such as digital cameras, PDAs, mobile phones, portable music players, and
digital voice recorders. The card is one of the smaller memory card formats, measuring
24mm wide by 32mm long and is just 2.1mm thick. To give the cards some orientation,
the top-right corner of each SD card is slanted.
Part of the reason the cards are called "Secure Digital" cards is because the cards
have a copyright protection feature built in. The security feature, called "key
revocation" means protected data on the card can only be read by specific devices.
What This Means To You: You will need either a card reader built
in to your computer or an external card reader. Keep in mind that some digital picture
frames can not handle big image files, so if you have trouble you may want to save
a copy of your image at a reduced size and save that to your SD Card. When you add
an SD Card to your scanning order, we will fill it with your newly scanned images
at a reduced resolution. This makes the file sizes more compatible to work with
Digital Picture Frames. Learn more about SD Cards!
External Hard Drive
The computer's hard drive is what stores all your data. It houses the hard disk,
where all your files and folders are physically located. A typical hard drive is
only slightly larger than your hand. It is a non-volatile storage device which stores
digitally encoded data on rapidly rotating platters with magnetic surfaces.
Hard drives are the storage medium in desktop and laptop computers as well as all
servers and mainframes throughout the world. Although removable disks encased in
cartridges use the same "hard" disk media and a similar drive technology, they are
mostly called "removable drives" rather than hard drives.
