10+ Lyncis Technologies Interview Questions and Answers
Q1. 6. Differences among method, constructor and deconstructor?
Method, constructor and destructor are all used in object-oriented programming to define and manipulate objects.
A method is a function that is associated with an object and can be called to perform an action on that object.
A constructor is a special method that is called when an object is created and is used to initialize the object's properties.
A destructor is a special method that is called when an object is destroyed and is used to clean up any resources that the object wa...read more
Q2. Why C is preferred over python in embedded systems
C is preferred over Python in embedded systems due to its low-level control and efficiency.
C allows for direct memory manipulation and low-level hardware access, which is necessary in embedded systems.
Python, on the other hand, is a high-level language that requires an interpreter, making it less efficient and slower than C.
C also has a smaller memory footprint and can be optimized for specific hardware, making it ideal for embedded systems.
Python is better suited for applica...read more
Q3. Write a program to sort an array of numbers
Program to sort an array of numbers
Use a sorting algorithm like bubble sort, insertion sort, or quicksort
Loop through the array and compare adjacent elements to swap them if necessary
Repeat until the array is sorted in ascending or descending order
Q4. Difference between microcontroller and micro processor
Microcontroller is a self-contained system with memory, input/output peripherals and a processor. Microprocessor only has a processor.
Microcontroller has on-chip memory and peripherals while microprocessor requires external memory and peripherals
Microcontroller is used in embedded systems while microprocessor is used in personal computers
Microcontroller is cheaper and consumes less power than microprocessor
Examples of microcontrollers are Arduino, PIC, and AVR while examples ...read more
Q5. What is the difference between array and list?
Array is a fixed-size data structure while list is a dynamic data structure.
Arrays have a fixed size while lists can grow or shrink dynamically.
Arrays store elements of the same data type while lists can store elements of different data types.
Arrays are accessed using an index while lists are accessed using an iterator.
Examples of arrays include int[], char[], and boolean[] while examples of lists include ArrayList and LinkedList.
Q6. Explain waterfall life cycle model and its stages?
Waterfall model is a linear sequential approach to software development.
It consists of five stages: Requirements, Design, Implementation, Testing, and Maintenance.
Each stage must be completed before moving on to the next.
It is a rigid model and changes cannot be made easily once a stage is completed.
It is suitable for projects with well-defined requirements and stable technology.
Example: Developing a calculator app.
Q7. Code to sort the numbers in ascending order
Use a sorting algorithm like bubble sort or quicksort to arrange numbers in ascending order.
Implement a sorting algorithm like bubble sort, selection sort, insertion sort, quicksort, etc.
For example, in bubble sort, compare adjacent elements and swap them if they are in the wrong order.
Repeat this process until the array is sorted in ascending order.
Q8. Does python have array data structure in it?
Yes, Python has array data structure in it.
Python has a built-in array module that provides an array() object
Arrays can be of any type, such as integers, floating-point numbers, and strings
Arrays are mutable and can be modified using various methods
Q9. 4. Explain Encryption and Decryption Techniques?
Encryption is the process of converting plain text into a coded message, while decryption is the process of converting the coded message back into plain text.
Encryption uses an algorithm to scramble the original message into an unreadable format.
Decryption uses a key to reverse the encryption process and retrieve the original message.
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses different keys.
Common encryption tec...read more
Q10. 5. Difference between overriding and overload?
Overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class. Overloading is when a class has two or more methods with the same name but different parameters.
Overriding is used for runtime polymorphism while overloading is used for compile-time polymorphism.
Overriding can only occur in a subclass while overloading can occur in the same class or its subclass.
Overriding changes the method behavior while overloading do...read more
Q11. Difference between big endian and small endian
Big endian and small endian are two ways of storing multi-byte data in computer memory.
Big endian stores the most significant byte first and the least significant byte last.
Small endian stores the least significant byte first and the most significant byte last.
The choice of endianess affects how data is interpreted and communicated between different systems.
For example, the IP protocol uses big endian for its header fields, while the x86 architecture uses small endian for its...read more
Q12. Write a program to swap two numbers
A program to swap two numbers
Declare two variables and assign values to them
Use a third variable to store the value of the first variable
Assign the value of the second variable to the first variable
Assign the value of the third variable to the second variable
Q13. 7. Explain program, process and thread?
Program is a set of instructions that performs a specific task. Process is an instance of a program in execution. Thread is a subset of a process.
Program is a set of instructions written in a programming language.
Process is an instance of a program in execution. It has its own memory space and system resources.
Thread is a subset of a process. It is a lightweight process that shares the same memory space and system resources as the parent process.
Multiple threads can run concu...read more
Q14. Draw and explain D flop truth table
D flip-flop is a digital circuit that stores a single bit of data and transfers it to the output on the rising edge of the clock signal.
D flip-flop has a single data input (D) and two outputs (Q and Q').
The truth table for D flip-flop is: D Q(t) Q(t+1), 0 0 0, 1 1 1.
The D input is sampled on the rising edge of the clock signal and transferred to the output.
The Q output is the complement of the Q' output.
D flip-flop is used in sequential circuits for storing and transferring d...read more
Q15. 3. Explain each layer of OSI?
OSI model has 7 layers that define how data is transmitted over a network.
Layer 1: Physical layer - deals with physical connections and electrical signals.
Layer 2: Data link layer - responsible for error-free transfer of data between nodes.
Layer 3: Network layer - handles routing of data packets between networks.
Layer 4: Transport layer - ensures reliable data transfer between end-to-end connections.
Layer 5: Session layer - establishes and manages communication sessions betwe...read more
Q16. What is bootloader
Bootloader is a program that loads and starts the operating system when a computer is turned on.
Bootloader is the first program that runs when a computer is turned on.
It is responsible for loading and executing the operating system.
Bootloader is usually stored in the computer's firmware or on the hard drive.
It performs hardware checks and initializes the system before loading the OS.
Examples of bootloaders include GRUB, LILO, and Windows Boot Manager.
Q17. 2. Explain OOPs Concepts?
OOPs concepts are the principles of Object-Oriented Programming that help in designing and implementing software systems.
Encapsulation - bundling of data and methods that operate on that data
Inheritance - creating new classes from existing ones
Polymorphism - ability of objects to take on many forms
Abstraction - hiding implementation details and showing only functionality
Example: A car is an object that encapsulates data such as speed, fuel level, and methods such as accelerat...read more
