Navitasys India Assistant Engineer Interview Questions, Process, and Tips for Experienced

An ideal diode is a theoretical diode that exhibits zero voltage drop when forward biased and infinite resistance when reverse biased.

• An ideal diode acts as a perfect conductor when forward biased.

• It allows current to flow in one direction with zero voltage drop.

• When reverse biased, it acts as an open circuit with infinite resistance.

• The input-output characteristic curve of an ideal diode is a vertical line at zero vol...read more

Program to compute factorial of a number using recursion

• Define a function that takes a number as input

• Check if the number is 0 or 1, return 1 if true

• Else, call the function recursively with n-1 as input and multiply with n

• Return the result

• Example: factorial(5) = 5 * factorial(4) = 5 * 4 * factorial(3) = 5 * 4 * 3 * factorial(2) = 5 * 4 * 3 * 2 * factorial(1) = 5 * 4 * 3 * 2 * 1 = 120

The OSI model has 7 layers that define how data is transmitted over a network.

• Layer 1: Physical - deals with the physical connection of devices

• Layer 2: Data Link - responsible for error-free transfer of data between devices

• Layer 3: Network - handles routing of data between different networks

• Layer 4: Transport - ensures reliable delivery of data between applications

• Layer 5: Session - establishes and manages connections ...read more

Session layer manages and controls the connections between applications.

• Establishes, maintains and terminates sessions between applications

• Synchronizes data exchange between applications

• Manages session checkpoints and recovery

• Examples: Telnet, FTP, SMTP

A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage is reached.

• Zener diodes are commonly used as voltage regulators.

• They have a sharp breakdown voltage, which makes them useful for stabilizing voltage in electronic circuits.

• Zener diodes are often used in power supplies, voltage references, and surge protectors.

• They are also used in noise reduction circuits and as...read more

• He has been associated with ISRO for over three decades and has contributed to several missions.

• Under his leadership, ISRO has achieved several milestones including the successful launch of Chandrayaan-2.

Program to print first 10 natural numbers on the screen

• Declare a variable i and initialize it to 1

• Use a loop to print i and increment it until i reaches 10

An IP address is a unique numerical identifier assigned to every device connected to the internet.

• IP stands for Internet Protocol

• It consists of four sets of numbers separated by dots

• Each set can range from 0 to 255

• Example: 192.168.1.1 is an IP address

• IPv4 and IPv6 are the two versions of IP addresses
