Nov / Dec 2015 Important Questions
Velammal Engineering College
The given 25 questions are important questions and one can get just pass marks if the University question is standard. If question paper is twisted, this may not help. So I request the students to study the below, only if anybody find it difficult to pass. Others should study the entire syllabus OR first study these questions, and then study the remaining. STUDY IN THE SAME SERIAL NUMBER ORDER GIVEN. DON’T SHUFFLE.
1. Draw and explain the architecture of 8085.
2. Draw and explain data flow of 8085.
3. With neat sketches, explain the signals and various modules of Intel 8051 microcontroller.(Architecture)
