Translator programs called assemblers convert assembly-language programs to machine language at computer speeds.

   

Interpreter programs, developed to execute high-level language programs directly, avoid the delay of compilation, and run faster than compiled programs.

Which of the following statements best explains why
nitrogen gas at STP is less dense than Xe gas at STP?
(a) Because Xe is a noble gas, there is less tendency for the Xe
atoms to repel one another, so they pack more densely in
the gaseous state.
(b) Xe atoms have a higher mass than N2 molecules. Because
both gases at STP have the same number of molecules per
unit volume, the Xe gas must be denser.
(c) The Xe atoms are larger than N2 molecules and thus take
up a larger fraction of the space occupied by the gas.
(d) Because the Xe atoms are much more massive than the
N2 molecules, they move more slowly and thus exert
less upward force on the gas container and make the gas
appear denser.
