Why V. Rajaraman’s "Fundamentals of Computers" Remains a Bestseller

Before you download any PDF, it is crucial to understand the author’s credibility. Prof. V. Rajaraman is a Padma Shri awardee and a pioneer in computer science education in India. He authored the first-ever textbook on computer science in the country.

Unlike other technical books that drown readers in jargon, Rajaraman’s writing style is lucid, logical, and student-friendly. The book bridges the gap between theoretical concepts (like Boolean algebra) and practical applications (like Microsoft Office or programming logic). This is why teachers across universities in Asia, Africa, and the Middle East still prescribe this text for BCA, B.Sc (CS), and B.Tech first-year courses.

Step 2: Solve Numerical Problems

The book contains unsolved end-of-chapter problems. Pay special attention to:

• Number system conversions (Binary to Hex, etc.)
• Binary addition/subtraction using 1’s and 2’s complement
• Truth tables for logic gates
