Modems
- Modems allow you to communicate with other computers using a phone
line. Modem speeds are in bits per second (14.4, 28.8 and 56 thousand bits
per second are standard).
CD-ROM Drives
- A CD-ROM drive is a high capacity storage device which lets you read
data from the disk, but not write data back. The speed of the drive (how
fast the CD platter spins) is measured in multiples from the first
generation drives. New drives are up to 24X (or 24 times the first drives),
but while the CD spins faster, it is not really 24 times faster in actual
output.
Printers
- There are different types of printers (laser, ink jet, dot matrix) with
differing quality of output. They are measured in dpi (dots per inch) and
ppm (pages per minute), the higher the better.
Scanners
- Scanners "digitize" printed material (like photos and graphics) and
save it to a graphic file format (like .GIF or .JPG) for display on the
computer.
