	and MPEG-4. H.264 typically achieves a coding efficiency around three times as high as MPEG-
	2. This means that comparable quality can be achieved at around a third of MPEG-2 data
	quantity.

HTTPS	Hypertext Transfer Protocol Secure: encrypts and authenticates communication between Web
	server and browser

	decimal notation, for example "209.130.2.193"
iSCSI	Storage over IP process for storage networks; specifies how storage protocols are operated
	over IP
ISDN	Integrated Services Digital Network

	J
JPEG	An encoding process for still images (Joint Photographic Experts Group)
	K
kbps	Kilobits per second, the actual data rate
