Embedded Computer Trivia Questions

1.

The Personal Computer (PC) is

A.

A dedicated computer
B.

A general purpose computer
C.

An embedded computer

Correct Answer
B. A general purpose computer

Explanation
A personal computer (PC) is classified as a general-purpose computer because it is designed to perform a wide range of tasks and can be used by individuals for various purposes. Unlike dedicated computers that are built for specific functions or embedded computers that are integrated into other devices, a PC is versatile and can be used for activities such as word processing, internet browsing, gaming, and multimedia tasks. It is not limited to a single function or application, making it suitable for general use by individuals in different settings.

2.

Which of the following is not an example of an embedded (dedicated) computer?

A.

Controller chip in an automatic washing machine
B.

Controller chip in an ABS
C.

Netbook

Correct Answer
C. Netbook

Explanation
A netbook is not an example of an embedded (dedicated) computer because it is a portable personal computer designed for general-purpose use. Embedded computers, on the other hand, are specialized systems that are built into other devices or machinery to perform specific functions. The controller chips in an automatic washing machine and an ABS are examples of embedded computers as they are dedicated to controlling and managing the respective devices' operations.

Which of the folowing is an example of an output device that is likely to be founf on a dedicated computer?

A.

Keypad on a microwave oven
B.

LED lights on microwave oven
C.

Keyboard used with a PC

Correct Answer
B. LED lights on microwave oven

Explanation
LED lights on a microwave oven are an example of an output device that is likely to be found on a dedicated computer. Output devices are used to display or present information from a computer system to the user. In this case, the LED lights on the microwave oven serve as an output device to indicate the status or settings of the microwave. While the keypad on the microwave oven can also be considered an input and output device, the LED lights specifically serve the purpose of outputting information. The keyboard used with a PC is not an example of an output device, as it is primarily an input device for entering data into the computer.

Process Control systems (eg. a Thermostat) generally use input they get from

A.

Sensors
B.

LED lights
C.

Mouse

Correct Answer
A. Sensors

Explanation
Process Control systems, such as thermostats, rely on input from sensors to monitor and regulate various parameters. Sensors detect changes in temperature, pressure, humidity, or other variables, and provide this information to the control system. Based on the sensor readings, the control system can make adjustments to maintain the desired conditions. This ensures that the system operates efficiently and effectively. LED lights and a mouse are not typically used as input for process control systems.

Autopilot computerised systems

A.

Are completely reliable
B.

Tend to be more reliable and consistent than humans
C.

Both the above are correct

Correct Answer
B. Tend to be more reliable and consistent than humans

Explanation
Autopilot computerized systems tend to be more reliable and consistent than humans. This is because these systems are designed to follow precise algorithms and instructions, eliminating the possibility of human error or fatigue. Unlike humans, autopilot systems do not get distracted, tired, or emotional, which can affect their performance. Additionally, these systems can process vast amounts of data and make split-second decisions, ensuring a higher level of accuracy and efficiency. However, it is important to note that autopilot systems may still have limitations and can encounter technical failures, but overall, they are considered to be more reliable than human operators.
