If we use a computer for many hours (as people often do at work), what health issues might affect us?
-
Eye-Strain
-
Back and Neck Ache,Repetitive Strain Injury (RSI) in Wrists and Hands
-
Brain cancer
-
Nothing
Correct Answer(s)
A. Eye-Strain
A. Back and Neck Ache,Repetitive Strain Injury (RSI) in Wrists and HandsExplanation
Using a computer for long hours can lead to various health issues. One common problem is eye strain, which occurs due to staring at a screen for extended periods. Additionally, sitting in the same position for hours can cause back and neck ache. The repetitive movements involved in typing and using a mouse can lead to repetitive strain injury (RSI) in the wrists and hands. Therefore, it is important to take breaks, practice good posture, and use ergonomic equipment to minimize the risk of these health issues.Rate this question:

Look away from the monitor at regular intervals – re-focus on distant or close objects to exercise the muscles in the eye can solve the eye-strain.
-
True
-
False
Correct Answer
A. TrueExplanation
Taking regular breaks and looking away from the monitor to focus on distant or close objects helps to exercise the eye muscles and alleviate eye strain. This is because staring at a screen for long periods can cause eye fatigue and strain, leading to symptoms such as dryness, blurred vision, and headaches. By practicing this habit, the eyes are given a chance to rest and refocus, reducing the strain caused by prolonged screen use. Therefore, the statement is true.Rate this question:

Many people suffer from back and neck pain after working at a computer for a long time. This is usually due to them having a __________.
Correct Answer
bad sitting postureExplanation
Many people experience back and neck pain after prolonged computer use because they have a bad sitting posture. Sitting in a slouched position or hunching over the computer can strain the muscles in the back and neck, leading to discomfort and pain. Maintaining a proper sitting posture, with the back straight and supported, can help alleviate these issues and promote better spinal alignment.Rate this question:

Back and Neck Ache can be solved by setting the computer keyboard and monitor at the correct height for the seated person (keyboard higher than the elbow, top of monitor lower than at eye level).
-
True
-
False
Correct Answer
A. FalseExplanation
The statement suggests that setting the computer keyboard and monitor at the correct height can solve back and neck ache. However, this is not entirely true. While having an ergonomic setup can help alleviate discomfort, it may not completely solve back and neck ache. Other factors such as posture, duration of computer use, and overall ergonomics of the workstation also play a significant role in preventing and managing back and neck pain.Rate this question:

What areas have the increase of Employment after the personal computer (PC) was developed in the early 1980s?
-
Manufacturing
-
Web Designers
-
IT Technicians
-
Newspaper Printing
Correct Answer(s)
A. Web Designers
A. IT TechniciansExplanation
After the development of personal computers (PCs) in the early 1980s, the areas that experienced an increase in employment were web designers and IT technicians. This is because the rise of PCs led to the growth of the internet and the need for professionals who could design and maintain websites, as well as handle the technical aspects of computer systems. Manufacturing and newspaper printing, on the other hand, may not have seen a significant increase in employment as a direct result of PC development.Rate this question:

Often microcontrollers also contain ____ and _____ to allow easy connection to devices such as sensors and actuators.
-
ADCs
-
CPUs
-
DACs
-
RAMs
Correct Answer(s)
A. ADCs
A. DACsExplanation
Microcontrollers often contain ADCs (Analog-to-Digital Converters) and DACs (Digital-to-Analog Converters) to allow easy connection to devices such as sensors and actuators. ADCs convert analog signals from sensors into digital signals that can be processed by the microcontroller, while DACs convert digital signals from the microcontroller into analog signals that can be used to control actuators. These components are essential for interfacing with the analog world and enabling the microcontroller to interact with external devices.Rate this question:

Plugging too many power cables into a socket can result in the socket being ________, overheating, and a fire starting.
Correct Answer(s)
overload
overloadedExplanation
Plugging too many power cables into a socket can result in the socket being overloaded, overheating, and a fire starting. When a socket is overloaded, it means that it is being asked to supply more electrical current than it is designed to handle. This can cause the wires inside the socket to overheat, leading to a potential fire hazard. Therefore, it is important to ensure that the number of power cables plugged into a socket does not exceed its capacity to prevent overloading and potential dangers.Rate this question:
