Another hardware term to know is port. Computer systems have ports into which the input and output devices are plugged. See examples below. Ports must be compatible with plugs or adaptors must be used.
So what is all the fuss about an 80 Gigabyte ( 80 million characters) hard disk drive? Not too long ago a hard disk drive could only store 300 million characters. Now they store upwards of 80 million characters. Hard disks, floppy disks, CD's (compact disks) of various sorts, zip disks, and DVD's (digital video disks) are all storage devices and serve to both input data to and output information from a computer system. They may be found inside the system box or external, plugging into a port at the back or side of the unit. Try not to confuse a storage device with the computer system memory (RAM or ROM) This issue has become a bit clouded. Memory cards for digital devices such as digital cameras are actually storage devices. However, the RAM internal to a computer system is temporary while the storage devices keep data, instructions, and information permanently - until a user deletes them.
