A phrase used to describe whether letters are typed in uppercase or lowercase. Some computer programs and network services are "case sensitive," meaning "XYZ" is considered different data than "xyz," for example. Certain Internet users are case sensitive, too, and many opt to type in all lowercase (which really bothers some people, but hey-it's the way of the Web; get used to it). Note: IF YOU TYPE IN ALL UPPERCASE, IT IS THE VISUAL EQUIVALENT OF SHOUTING and a breach of netiquette.
