    Everyone has their own way of explaining it. The ISA is the bridge, or the interface, between the hardware and the software. Or it’s the blueprint. Or it’s the computer’s DNA. These are helpful enough, as is the common comparison of an ISA to a language. “You and I are using English,” as [Calista Redmond] said to me at the conference. “That’s our ISA.” But it gets confusing. Software speaks in languages too—programming languages. That’s why [David Patterson] prefers dictionary or vocabulary. The ISA is less a specific language, more a set of generally available words.

    It's an awkward name: Isamay, pronounced Is-a-may. Isa is my paternal grandmother's name (shortened from Isabel) and May my maternal grandmother's (it comes, somehow, from Margaret).
