Computer memory is being discussed. Technician A says RAM-type memory is erased when the vehicle's battery is disconnected from the computer. Technician B says ROM memory can be erased with a scan tool. Who is correct?

Technician A says N-type semiconductors have loose, or excess, electrons. Technician B says P-type semiconductors are positively charged materials. Who is correct?

Before an analog sensor signal can be processed by a computer, it must first be converted into a digital format.

What is the major difference between ROM and RAM memory in a microprocessor?

_____ allows control modules to share sensor and output status information without the need for additional sensors or wiring.

Technician A says some types of voltage sensors provide input to the computer by modifying or controlling a constant, predetermined voltage signal. Technician B says some types of voltage sensors provide a voltage generating signal. Who is correct?

Which of the following is not a type voltage generating sensor?

A(n)____________________ is the simplest type of semiconductor.

The four basic functions of a computer are input, output, processing, and _____.

The voltage applied to the _____ of a transistor controls the flow of electric current through the transistor.

Technician A says the primary purpose of a multiplexing system is to send and receive multiple analog signals. Technician B says multiplexing uses bus data links. Who is correct?

____________________ means that data concerning the effects of the computer's commands are fed back to the computer as an input signal.
