Computer Fundamental Interview Questions & Answers
Showing 10 of 56 questions | Page 2
Technical interview questions and answers form the base of any Computer Fundamental Interview because companies want to evaluate a candidate’s basic understanding of computers, number systems, memory, input/output, software types, operating systems, and logic building. These fundamental concepts help interviewers judge whether a candidate is ready for technical roles, IT support jobs, programming positions, or general office operations. Companies like TCS, Infosys, Wipro, Cognizant, and Accenture frequently ask fundamental questions in campus placements and initial screening rounds. This guide covers frequently asked Computer Fundamental interview questions with clear explanations to help freshers and job seekers strengthen their basics. Preparing these questions will help you perform confidently in written tests, technical interviews, and aptitude-based assessments.

11. What is the difference between RISC and CISC architectures
RISC (Reduced Instruction Set Computer) architecture uses a small set of simple instructions, while CISC (Complex Instruction Set Computer) architecture uses a larger set of more complex instructions
12. Discuss the importance of file systems in an operating system
File systems manage how data is stored and retrieved on a disk, providing a way to organize, store, and access files efficiently
13. How does paging differ from segmentation in memory management
Paging divides memory into fixed-size pages, while segmentation divides it into variable-sized segments based on logical divisions, such as functions or data structures
14. Explain the concept of pipelining in computer architecture
Pipelining is a technique where multiple instruction phases are overlapped to improve CPU performance by executing different parts of instructions simultaneously
15. What is the purpose of DMA in a computer system
Direct Memory Access (DMA) allows hardware subsystems to access system memory directly, bypassing the CPU, to speed up data transfer rates
16. How do operating systems manage process scheduling
Operating systems use process scheduling algorithms to determine the order in which processes are executed, optimizing CPU utilization and ensuring efficient process management
17. What are interrupts and how are they handled by the operating system
Interrupts are signals that indicate an event requiring immediate attention, and the operating system handles them by temporarily halting the current process, executing an interrupt handler, and then resuming the process
18. Explain the concept of virtual machines and their use cases
Virtual machines are software emulations of physical computers, allowing multiple operating systems to run on a single physical machine, often used for testing, development, and server consolidation
19. What is the difference between symmetric and asymmetric multiprocessing
Symmetric multiprocessing involves multiple processors sharing the same memory and I/O resources equally, while asymmetric multiprocessing assigns different tasks to different processors
20. Describe the functioning of a disk scheduling algorithm
Disk scheduling algorithms determine the order in which disk I/O requests are processed, aiming to reduce seek time and improve disk throughput
