Aricent Technologies Technical Interviews Question Bank continued from Part 6
Q-31. What are the different flags supported by the 8086 microprocessor?
A : The 8086 microprocessor has the following flags – carry flag, auxiliary carry flag, parity flag, zero flag, overflow flag, trace flag, interrupt flag, direction flag, and sign flag.
Q-32. Which type of stack is used in 8086?
A : The 8086 microprocessor uses LIFO (Last In First Out) stack in which the element which is inserted last, gets removed first.
Q-33. What is Stack Pointer?
A : Stack Pointer or SP is a Special Function Register (SFR) in microprocessor/microcontroller which contains the address of the top of the stack.
Q-34. What is Program Counter?
A : Program Counter or PC is a Special Function Register (SFR) in microprocessor/microcontroller which contains the address of the first byte of next instruction or next byte of a multi-byte instruction to be fetched for execution of a program.
Although Aricent (or any other ECE core company) focuses more on ECE subjects, apart from the above ECE questions, some Computer Science (Programming) questions preparation would improve your chances of selection. Here are some of them which I came across during Aricent interviews –
- Sorting algorithms
- Linked list formation
- Insertion and deletion of nodes at various positions of the Linked list.
- push() and pop() implementation using linked list
- Program for fibonacci series
- Program for factorial of a number
- Program for swapping two numbers (with and without using third variable)
- Some questions on pointers
- Program implementation of important Object Oriented Programming (OOP) concepts
- What is getch()?
- What is conio.h?
- Important DBMS concepts and writing SQL queries.
I hope the above hints would help during your preparation for ECE core companies specially. Remember that the more preparation you do, the more you increase your chances of selection. The above questions provide you hints to the important and frequently asked topics in ECE core companies. For detailed information of these questions/topics, ask your teachers, consult textbooks or search on the internet to get a clear picture of everything. Read here my interview experience of Aricent Technologies. Thanks for being a patient reader 🙂 !.
All the best!
