Question 1

Communication controllers in microcontrollers _________.
A) support only UART communication
B) allow microcontrollers to communicate with other devices using specific communication protocols
C) require a separate external clock source to operate
D) require little configuration to operate

Accepted Answer

Communication controllers in microcontrollers are designed to allow microcontrollers to communicate with other devices using specific communication protocols such as UART, SPI, I2C, etc. They do not support only one type of communication, do not always require a separate external clock source, and often require detailed configuration to operate correctly.

Question 2

Pulse width modulation can be used to control a motor by using the duty cycle to_________.
A) change the amplitude of the winding current
B) change the amplitude of the winding voltage
C) change the effective voltage applied to the motor winding
D) change effective current delivered to the motor winding

Accepted Answer

The answer of Pulse width modulation can be used to...

Question 3

Microcontrollers contain external memory controllers because _________.
A) communication controllers and other peripherals require external memory to operate
B) some microcontrollers do not contain any internal memory
C) all microcontrollers require an external ROM to boot up
D) all of the above

Accepted Answer

Some microcontrollers do not contain any internal memory, necessitating the use of external memory controllers to interface with external memory.

Question 4

An assembler is used to _________.
A) write and edit assembly language programs
B) convert assembly language to machine code
C) convert the assembly language for one processor to the assembly language for another processor
D) convert a high- level language to assembly language

Accepted Answer

An assembler is specifically designed to convert assembly language code into machine code, enabling the computer to execute the instructions.

Question 5

A compiler _________.
A) converts machine code into assembly language
B) converts assembly language into a high- level language
C) allows machine code for one processor to run on another processor
D) converts a high- level language to machine code

Accepted Answer

A compiler translates code written in a high-level programming language into machine code, enabling the computer to understand and execute the instructions.

Question 6

An advantage of assembly language programs is_________.
A) they can run on any processor
B) they typically run faster than programs written in a high- level language
C) they can use the same compiler tools as high- level languages
D) they are well- suited for large and complex applications

Accepted Answer

Assembly language programs are closer to machine code compared to high-level languages, allowing them to execute more efficiently and often faster, as they can be optimized for specific hardware.

Question 7

All of the following are processor instruction types except_________.
A) arithmetic
B) data transfer
C) loops and jumps
D) encryption

Accepted Answer

Encryption is not a processor instruction type; it is a process or function that can be implemented using various instructions.
