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.

51. What is the role of a device driver in an operating system
Device drivers are specialized programs that allow the operating system to communicate with hardware devices, providing the necessary interface and control functions
52. Describe the process of booting in a computer system
Booting is the process of starting up a computer and loading the operating system into memory, involving steps like power-on self-test (POST), loading the bootloader, and initializing the kernel
53. What is thrashing in the context of memory management
Thrashing occurs when a system spends more time swapping pages in and out of memory than executing actual processes, leading to severe performance degradation
54. Explain the difference between batch processing and real-time processing
Batch processing involves executing a series of jobs without manual intervention, while real-time processing requires immediate processing and response to inputs, often used in time-sensitive applications
55. What is the purpose of the kernel in an operating system
The kernel is the core component of an operating system that manages system resources, handles communication between hardware and software, and provides essential services for application execution
56. 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
