Recruitment by Cisco:
Cisco recruits candidates either through campus recruitment in colleges or through its own offices in different parts of the nation. Irrespective of the place of recruitment, the company recruits candidates by conducting recruitment examination in the form of written test followed by interview.
Cisco placement exam pattern
CISCO selects technical candidates through written test for a duration of one hour and the question paper for this written examination will have three sections, where in section 1 will be common for all candidates and second and third section will have questions based on the specialization branch of candidates. The first section of the question paper will have questions from the following areas:
• Number representations
• Small numerical
• Virtual memory
• Microprocessor
• Architecture
• Flip flops
• Digital logic design
The second section of the question paper will be devoted for questions from software related areas, while third section is meant for questions from hardware area.

Cisco Interview Procedure
Interview Procedure :
The written test is followed by a lengthy technical interview. The interview may last up to 1 hour or more. It is entirely technical with questions on all basic fundamentals.

ANS: 10
11. In memory mapped I/O how I/O is accessed………….
ANS: Just like a memory location (Means, I/O devices can be accessed using the instructions like mov A,M etc…)
12. What is the use of ALE in 8085…….
