This round started with some questions from Programmable Logic Controllers or PLC followed by some basic questions from Intel 8051 Microcontroller.
PLCs are used to control machinery and automate processes in industrial settings.
Monitoring inputs from sensors
Executing control algorithms
Communicating with other devices
Logging data for analysis
Implementing safety functions
Examples: controlling a conveyor belt, regulating temperature in a furnace
Ladder logic programming is a graphical programming language used for PLCs, with basic elements like contacts, coils, timers, and counters.
Ladder logic consists of rungs, which are made up of inputs (contacts) and outputs (coils).
Contacts represent conditions that must be met for the output to be energized.
Coils are outputs that are energized when the conditions of the contacts are met.
Timers and counters are used to c...
PLC inputs and outputs include digital inputs, digital outputs, analog inputs, and analog outputs.
Digital inputs: used for receiving binary signals (on/off, high/low). Examples: push buttons, limit switches.
Digital outputs: used for sending binary signals. Examples: relays, solenoids.
Analog inputs: used for receiving continuous signals. Examples: temperature sensors, pressure transducers.
Analog outputs: used for sendin...
The S7 controller offers high performance and flexibility but can be complex to program and expensive.
Advantages: high performance, flexibility, scalability
Disadvantages: complexity in programming, expensive
Example: S7-1200 offers fast processing speeds and can be easily expanded with additional modules
Example: Programming for S7 controllers may require specialized training and expertise
The time stamp in S7-200 PLC is used to record the time when a specific event occurs.
Time stamp is a feature in S7-200 PLC that records the time when a specific event happens.
It helps in tracking the sequence of events and troubleshooting issues.
Time stamp can be used to monitor the performance of the PLC system.
Example: A time stamp can be recorded when a sensor detects a change in temperature.
Example: Time stamp can ...
Jnc stands for Jump and Call in the context of microcontrollers.
Jnc is an instruction used in microcontrollers to jump to a specified address if the carry flag is not set.
It is commonly used in conditional branching operations in microcontroller programming.
For example, in 8051 microcontroller assembly language, the instruction JNC label will jump to the specified label if the carry flag is not set.
The types of interrupts in the Intel 8051 microcontroller include external hardware interrupts, timer interrupts, and serial communication interrupts.
External hardware interrupts are triggered by external devices connected to the microcontroller.
Timer interrupts are generated by the internal timers of the microcontroller.
Serial communication interrupts occur when data is received or transmitted through the serial port.

Round duration - 50 Minutes
Round difficulty - Medium
This round was heavily inclined towards Operating System and Computer Networks and the interviewer asked questions revolving around the fundamentals of the subject.
A bootstrap program is a small program that initializes the operating system on a computer.
Bootstrap program is stored in ROM or EEPROM and is executed when the computer is powered on.
It loads the operating system kernel into memory and starts its execution.
Bootstrap program is responsible for setting up the initial state of the operating system.
Examples include BIOS (Basic Input/Output System) in PCs and UEFI (Unified
Demand paging is a memory management scheme where pages are only brought into memory when they are demanded by the program.
Pages are loaded into memory only when needed
Helps in reducing the amount of physical memory required
Improves overall system performance by allowing more processes to run simultaneously
Commonly used in virtual memory systems
Five essential UNIX commands are ls, cd, pwd, mkdir, and rm.
ls - list directory contents
cd - change directory
pwd - print working directory
mkdir - make directory
rm - remove files or directories
Different types of VPN include remote access VPN, site-to-site VPN, and client-to-site VPN.
Remote access VPN allows individual users to connect to a private network from a remote location.
Site-to-site VPN connects entire networks together over the internet.
Client-to-site VPN allows individual devices to connect to a private network.
Examples include OpenVPN, IPsec, and SSL VPN.
The OSI Reference Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.
The OSI Reference Model stands for Open Systems Interconnection Reference Model.
It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific functions and communicates with the adjacent layers for data trans...
TCP is a connection-oriented protocol that ensures reliable data delivery, while UDP is a connectionless protocol that focuses on speed.
TCP stands for Transmission Control Protocol and is used for reliable data transmission.
TCP establishes a connection between sender and receiver before data transfer.
TCP uses sequencing and acknowledgment to ensure data integrity.
UDP stands for User Datagram Protocol and is used for fa...
