What is the primary cause of time drift in a computer system?
Too many applications running simultaneously
Defective power supply units
Frequent updates to the operating system
Inaccurate hardware clock adjustments
Inaccurate hardware clock adjustments - This is correct. Time drift occurs when the system's hardware clock (often a real-time clock or RTC) becomes inaccurate due to factors such as crystal oscillator imperfections, temperature variations, or aging components. This results in the system time gradually drifting away from the accurate time.
Frequent updates to the operating system - Operating system updates typically do not affect the system clock and are not a cause of time drift.
Defective power supply units - A defective power supply can cause other hardware issues, but it is not a primary cause of time drift. The RTC is usually powered by a small battery independent of the main power supply.
Too many applications running simultaneously - Running multiple applications can impact system performance, but it does not cause time drift, which is related to hardware clock accuracy.
