Enosis Solutions Technical Software Lead Interview Questions and Answers for Experienced

OOPs is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPs stands for Object-Oriented Programming.

• It focuses on creating objects that interact with each other to solve a problem.

• It uses concepts like inheritance, encapsulation, and polymorphism.

• Inheritance allows a class to inherit properties and methods from another class.

• Encapsulation is the practice of hiding data and method...read more

Constructor and destructor are special member functions in a class that are used to initialize and destroy objects respectively.

• Constructor is called when an object is created and is used to initialize the object's data members.

• Destructor is called when an object is destroyed and is used to free up any resources that the object was using.

• Constructor has the same name as the class and no return type, while destructor ha...read more

Polymorphism is the ability of an object to take on many forms.

• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• It is achieved through method overriding and method overloading.

• Example: A parent class Animal can have child classes like Dog, Cat, and Cow. All these child classes can have a method called 'makeSound', but each class can have a different implementation of the m...read more

To raise a defect, follow these steps:

• Identify the defect and reproduce it if necessary

• Document the defect with a clear and concise description

• Assign a severity level to the defect

• Assign the defect to the appropriate team or individual

• Track the status of the defect until it is resolved

Automation saves time and increases accuracy.

• Automation can run tests faster than humans

• Automation can perform repetitive tasks without getting tired or making mistakes

• Automation can simulate large amounts of data to test edge cases

• Automation can provide consistent results

• Manual testing is prone to human error and can be time-consuming

• Automation can free up human testers to focus on more complex testing tasks

C is a programming language used for system programming, embedded systems, and game development.

• C was developed by Dennis Ritchie at Bell Labs in 1972.

• It is a compiled language, meaning that the code is translated into machine-readable instructions before execution.

• C is known for its efficiency and low-level control over hardware, making it a popular choice for operating systems and device drivers.

• C functions are defin...read more

Header files are used to declare functions, variables, and constants that are used in multiple source files.

• Header files allow for modular programming and code reuse.

• They help to avoid code duplication and reduce errors.

• Examples of header files include stdio.h, math.h, and string.h.

• Header files are included using the #include preprocessor directive.

A microprocessor is a small computer chip that performs arithmetic and logic operations.

• Microprocessors are the heart of modern computers and electronic devices.

• They are made up of millions of transistors that switch on and off to perform calculations.

• Microprocessors fetch instructions from memory, decode them, and execute them.

• Examples of microprocessors include Intel's Pentium and AMD's Ryzen processors.

• Microprocesso...read more

Micro control is a type of control system that uses microprocessors to control various devices and processes.

• Micro control systems are used in various applications such as home automation, industrial automation, and robotics.

• They are designed to be compact and efficient, with low power consumption and high processing power.

• Micro control systems can be programmed using various programming languages such as C, C++, and a...read more

Embedded systems are computer systems designed to perform specific tasks within a larger system.

• Embedded systems are often used in devices such as medical equipment, automobiles, and home appliances.

• They typically have limited processing power and memory compared to general-purpose computers.

• They are designed to be reliable and efficient, often running on low-power processors.

• Programming languages commonly used for emb...read more

A network is a group of interconnected devices that communicate with each other. There are three types of networks: LAN, WAN, and MAN.

• A LAN (Local Area Network) is a network that covers a small area, like a home or office.

• A WAN (Wide Area Network) is a network that covers a large area, like a city or country.

• A MAN (Metropolitan Area Network) is a network that covers a larger area than a LAN but smaller than a WAN, like...read more

Modulation is the process of varying a signal's characteristics to transmit information.

• Modulation is used in various communication systems to transmit information over a distance.

• It involves varying one or more of the signal's properties such as amplitude, frequency, or phase.

• Examples of modulation techniques include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).

Amplitude is the measure of the height of a wave from its resting position.

• Amplitude is the maximum displacement of a wave from its equilibrium position.

• It is measured in units of length, such as meters or feet.

• In sound waves, amplitude determines the loudness of the sound.

• In light waves, amplitude determines the brightness of the light.

• Amplitude can be positive or negative, depending on the direction of the displaceme

Use is the purpose or function of something.

• Use defines the intended purpose of a product or service.

• It helps users understand how to utilize the product effectively.

• Use can also refer to the act of employing something for a specific task.

• For example, the use of a hammer is to drive nails into wood.

Amplification is the process of increasing the magnitude of a signal.

• Amplification is commonly used in audio systems to increase the volume of sound.

• It can also refer to the process of increasing the power of an electrical signal.

• Amplification can be achieved through the use of amplifiers or other electronic devices.

• In genetics, amplification refers to the process of making multiple copies of a specific DNA sequence.

• Am...read more
