"Tech stocks" is a term that often makes us roll our eyes at Fool HQ, since it's rather meaningless. People often use the term to refer to computer-related companies and software companies. But, these days, it can be hard to think of companies that don't employ a fair amount of technology.

Think of pharmaceutical firms, such as Pfizer (NYSE:PFE) and Merck (NYSE:MRK), for instance. Drug chemistry and drug delivery processes involve technology. Golf club manufacturers apply technology to their new product development. (New! Kryptonite clubs! Harder than titanium!)

Pretty much any airplane-related enterprise uses technology -- from building jets to booking flights. Likewise, FedEx (NYSE:FDX) and other delivery specialists rely heavily on technology. Of course, some companies do so more than others. Sun Microsystems (NASDAQ:SUNW), for example, is much more of a technology company than is Hershey (NYSE:HSY). But even Hershey employs a fair bit of technology, in its research and production.

When we hear that "Tech stocks were up today," we have to wonder what exactly is being said. A good way to think about the term might be to use it for companies that draw most of their revenue from directly using or creating technology.
