TCS Assistant Engineer Interview Questions and Answers

Generate a star pattern using a desired language.

• Use nested loops to print the desired number of rows and columns.

• In each iteration, print a '*' character to form the pattern.

• Adjust the loop conditions and print statements to create different patterns.

• Consider using variables to control the number of rows and columns.

• Experiment with different loop structures to create more complex patterns.

OOPs concepts are the fundamental principles of object-oriented programming.

• Abstraction: Hiding implementation details and showing only necessary information.

• Encapsulation: Binding data and functions together in a single unit.

• Inheritance: Acquiring properties and behavior of a parent class by a child class.

• Polymorphism: Ability of an object to take many forms.

• Example: A car is an object that has properties like co...read more

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 zer...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

• K. Sivan is an Indian space scientist and the current chairman of ISRO.

• 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

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 a...read more

An IP address is a unique identifier for a device on a network, enabling communication over the internet.

• IP stands for Internet Protocol, which is a set of rules for sending data over the internet.

• There are two main types of IP addresses: IPv4 (e.g., 192.168.1.1) and IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• IPv4 addresses are 32-bit numbers, while IPv6 addresses are 128-bit, allowing for a vastly large...read more
