The best way to prevent repetitive strain injury (RSI) is to:
Correct Answer
B. Take regular breaks from your computer.
Explanation
Regular breaks from computer work can help prevent repetitive strain injury (RSI) by giving the muscles and tendons in the hands, wrists, and arms time to rest and recover. Prolonged computer use can lead to overuse and strain on these muscles, which can result in RSI. Taking breaks allows these muscles to relax and reduces the risk of developing RSI.

This helps to identify any potential issues or errors that may prevent the system from booting up successfully.
27.
The operating system loads the moment the computer is switched on.
Correct Answer
B. False
Explanation
The statement is false because the operating system does not load the moment the computer is switched on. When a computer is turned on, it goes through a booting process where the hardware is initialized and the basic input/output system (BIOS) is activated. The BIOS then checks for a bootable device, such as a hard drive or a USB drive, and loads the operating system from that device. Therefore, the operating system loads after the computer is switched on, not immediately.
28.
Which of the following are examples of an operating system?
