Frequently Asked Questions (FAQs)

Q1: What is a binary digit (bit)? Ans: A binary digit, or bit, is the smallest unit of data in a computer, represented by either 0 or 1, matching the on/off states of electronic circuits.

Q2: What is the main purpose of a process scheduler? Ans: The primary goal of a process scheduler is to manage CPU utilization by deciding which process gets the processor’s time and when.

Q3: How do ASCII and Unicode differ? Ans: ASCII is a 7 or 8-bit code used for basic English characters, while Unicode is a larger standard (8 to 32 bits) that supports languages from all over the world.

Q4: What is an application patch? Ans: An application patch is a small software update designed to fix bugs, improve security, or enhance the performance of an existing program.

Q5: What is the difference between Multitasking and Multiprogramming? Ans: Multiprogramming keeps the CPU busy by loading multiple programs, while Multitasking allows a user to run several apps at once by switching between them very quickly.
