These are the questions not copied from anywhere. It is my original work. These are questions asked in interview for electronics and computer science students.
About the author: The author of this article is an engineering student of B.E. in ECE. He is not a geek nor a nerd, but has extreme interest in programming in 8051,8086,C,C++,html etc....
Tip for interview for ece students:
Revise almost all your subjects before your interview.
Prepare yourself for the worst case.
- 8086 is how many bit microprocessor?
- 8086 gave rise to which famous architecture?
- 8008 is how many bit processor?
- Which mos technology is used for 8086up?
- In 8086 all internal registers and buses are ____bits wide.
- The main four registers in 8086 are?
- The four index registers are?
- The four segment registers are?
- What are the flags in psw?
- Which instruction pointer is used here?
- Here the address bus used is of ____bits wide.
- The data bus was _____with the address bus in order to fit in standard 40 pin package.
- Here stack pointer is ___bits wide.
- Here instruction pointer is _____bits wide.
- Here flag register are _____bits wide.
- Here segment registers are _____bits wide.
- In 8086 input output space is _____kb.
- How many interrupts are there in 8086?
- What are the control flags present in 8086 up?
- 8086 has a____ bit flag register.
- Out of 16 bit flag register, how many are active. Also name them.
- How the physical address is calculated?
- What was the advantage of using 8 bit data bus in 8088?
- 8008 was launched in 1972, same year when Dennis Ritchie gave c.
- In 1974 8080 was launched.
- In 1977 8085 was launched, which could cope with single 5v supply instead of three different operating voltages.
- The 8086 project started in 1976.
- In the beginning 8086 was implemented using depletion load circuitary with about 20,000 transistors (29,000 counting all ROM and PLA sites). It was soon moved to HMOS.
- Physical address calculation:
- (16×segment + offset), therefore producing a 20-bit external (or effective or physical).
- The first pc of all times IBM used intel 8088, a version of 8086 with 8 bit data bus.
- The 1st commercial computer made using 8086up was Mycron 2000.
