A high quality CAD system uses the following for printing drawing and graphs

Answer: B

Correct answer: Digital plotter

A CAD drawing is made of lines, and a plotter draws them as lines - continuously, at large size and with high precision - rather than approximating them with a grid of dots. That is why plotters remained standard for engineering and architectural output long after dot-matrix and line printers had been displaced elsewhere.

Answer: B

Correct answer: Because they can stop or allow the flow of current

The name comes from the analogy with a plumbing valve: like a tap, the tube lets current flow one way and blocks it the other, and the grid can stop or allow that flow. Amplification is a further consequence - a small change at the grid produces a large change in the current - but it is the controlling of flow that gives the valve its name.

Answer: C

Correct answer: ROM and RAM

Main (primary) memory is of two kinds: RAM, which is read-write and volatile, and ROM, which is read-only and keeps its contents without power - where the start-up firmware lives. “Primary and secondary” describes main memory against disk, which is a different division altogether.

In most of the IBM PCs, the CPU, the device drivers, memory, expansion slots and active components are mounted on a single board. What is the name of the board?

Answer: A
