Computer Fundamental Interview Questions & Answers
Showing 10 of 56 questions | Page 4
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.

31. Discuss the use of memory-mapped I/O in computer systems
Memory-mapped I/O allows hardware devices to be controlled and accessed by reading and writing specific memory addresses, simplifying device management and improving performance
32. Explain the concept of virtual memory in an operating system
Virtual memory is a memory management technique that allows the execution of processes that may not be completely in memory, by extending the available memory through disk space
33. Describe the difference between multiprogramming and multitasking
Multiprogramming refers to running multiple programs on a single processor by rapidly switching between them, while multitasking involves running multiple tasks simultaneously, often on multiple processors
34. What is a deadlock and how can it be prevented in operating systems
A deadlock occurs when two or more processes are unable to proceed because each is waiting for the other to release a resource. It can be prevented by ensuring that at least one of the necessary conditions for deadlock is not met
35. Explain the significance of cache memory in a computer system
Cache memory is a small, high-speed memory located close to the CPU, used to temporarily store frequently accessed data and instructions to speed up processing
36. 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
37. 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
38. 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
39. 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
40. 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
