Basic Computer Awareness — MCQ Practice Questions

A strong grip on basic computer concepts is non-negotiable for any government exam aspirant. The Basic Computer Awareness topic covers the foundational building blocks that every competitive exam tests — and tests repeatedly. Questions in this section span the core input-output cycle, types and functions of memory (RAM, ROM, Cache), storage devices, central processing unit (CPU) architecture, operating system basics, and fundamental hardware components. These are the concepts that appear in the computer awareness sections of SSC CGL, SSC CHSL, SSC MTS, IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, RRB NTPC, RRB Group D, and dozens of state-level recruitment examinations every year. The quiz sets under this topic are structured to build your knowledge progressively. Start with Set 1 to assess your baseline, then move to Set 2 to reinforce and expand. Each question is paired with a focused explanation designed to eliminate confusion and lock in the correct concept. Key Subtopics: • Definition and working of a computer • Input devices vs Output devices • Types of memory: Primary & Secondary • CPU components: ALU, CU, Registers • Operating System functions • Basic hardware identification
