A program component that allows structuring of a program in an unusual way is known as
Answer: B
Correct answer: Coroutine
Ordinary procedures follow a strict call-and-return discipline. A coroutine instead suspends itself and hands control to another coroutine, later resuming exactly where it left off with its state intact, so two routines can advance in step - a structure that does not fit the usual hierarchy of calls.

A hybrid computer uses a _____ to convert digital signals from a computer into analog signals.
Answer: C
Correct answer: Modem
In a hybrid installation the digital machine’s output has to be presented to the analogue side as a continuously varying signal, and the modem performs that conversion: its modulator turns the bit stream into an analogue waveform, and its demodulator turns the returning waveform back into bits.

_____ is need to build dynamic web documents?
Answer: D
Correct answer: All of the above
A dynamic page is assembled rather than served ready-made, and all three have a hand in it: HTML supplies the structure the browser renders, CGI lets the server run a program that generates the page for each request, and Java (with applets and server-side code) supplies logic on either side. Since each plays a part, the combined option is right.
