Some devices handle both input and output functions. These devices are called input/output (I/O) devices, a term you will encounter quite often.
• Floppy disk drive
Mechanism for reading and writing to low-capacity, removable, magnetic disks. Used to store and easily transport information.
• Hard disk drive
High-capacity internal (and sometimes external) magnetic disks for storing data and program files. Also called fixed disks.
Converts computer data to information that can be transmitted over telephone wires and cable lines. Allows communication between computers over long and short distances.
• Network card
An expansion card that allows several computers to connect to each other and share information and programs. Also called network interface card (NIC).
• CD recorder
Also called CD-R. You can copy data to a CD with this device, but you can only write to a section of the disc once. Variations on this type of device include compact disc–rewritable (CD-RW) drives. These drives allow you to read, write, and overwrite a special CD-ROM-type disc.
• Tape drive
Large-capacity, magnetic, data storage devices. Ideal for backup and retrieval of large amounts of data. Works like a tape recorder and saves information in a linear format.
