This book is best for the freshers because of the simple language, very good flow of contents and better organization of the topics.

It also contains lot of material useful for quick revision before exams (review questions with answer, discussion questions, objective questions, points to remember)
Think boxes are really very good for reinforcing the concepts.
The book is also very useful to the teachers.

Though the author is not very famous, this is the most comprehensive guide on the 8051 micro controller available.

The language is lucid and the pace of the book is very steady. This makes it the most ideal book for beginners.
I would personally rate it above the books of 8051 by Kenneth Ayala and Muhammad Mazidi.

One of the best book beginner's

Easy to understood

Nice

The delivery was supposed to be made on 30th of June 2017 or 1st of July 2017. But it was delayed without any reason by 4 days and only delivered on the 4th of July 2017. I am happy that Flipkart has accepted the mistake from their end and gave me a gift card for the delivery charge amount of the product. I would definitely recommend purchase of items on flipkart to anyone.
