Disk A spinning platter of magnetic data storage media. If the platter is very stiff it is a hard drive, if it is highly flexible it is a floppy disk, if it is a floppy disk in a hard housing with a shutter it is commonly called a diskette. Disk Drive The hardware which spins the disk and has the heads and control circuitry for reading and writing the data on the disk. Diskette A floppy disk in a hard housing with a shutter.

Extended Memory All memory more than the 640KB recognized by MS-DOS as system memory. FCC Federal Communication Commission. Floppy Disk A spinning platter of magnetic data storage media which is highly flexible. GB Gigabyte. Hard drive A spinning platter of magnetic data storage media where the platter is very stiff. I/O Input/Output. Data entering and leaving your Tablet PC in electronic form. I/O Port The connector and associated control circuits for data entering and leaving your Tablet PC in electronic form. IDE Intelligent Drive Electronics. A type of control interface for a hard drive which is inside the hard drive unit. IEEE802.11a One of the wireless LAN standards prescribed by the 802 committee in charge of establishing standards of LAN technology in IEEE (Institute of Electrical and Electronic Engineers).
