Maintain elevation of underground piping by using level instruments and proper installation techniques.
Use a level instrument to check the elevation of the piping during installation.
Ensure that the piping is installed with a consistent slope to prevent low spots where water can accumulate.
Regularly inspect the piping to ensure that it has not shifted or settled, which can affect the elevation.
Consider using supports o...

Welding electrodes are chosen based on the material being welded. Different materials require different types of electrodes.
Electrodes for mild steel have a coating that produces a stable arc and minimal spatter.
Stainless steel electrodes have a coating that resists corrosion and produces a smooth, clean weld.
Cast iron electrodes have a high nickel content to prevent cracking.
Aluminum electrodes have a special coating ...
I was interviewed in Apr 2017.
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...
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 ...
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...

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
