Sure. "Laser" is a word too, and it's all acronym.
I'm more bothered by the omission of "s". The S in teraflops is not plural, it's part of the acronym.
Your computer has 1 teraflop performance? One trillion floating point operations per _what_, then?
Laser, sonar, radar. Many, if not most, acronyms become words on their own at some point in English, especially if they enter the popular lexicon (leave their initial niche).
