2. Difference between Set, List, Tuple, Dictionary. 

This is one of the most commonly asked Apisero Interview Questions. Set, List, Tuple, and Dictionary are all a collection of data. Let us look at all of them in detail.

• Lists: are just like dynamic-sized arrays, declared in other languages (vector in C++ and ArrayList in Java). Lists need not be homogeneous, making it the most potent tool in Python.
• Tuple: A Tuple is a comma-separated collection of Python objects. Regarding indexing, nested objects, and repetition, a tuple is comparable to a list, but a tuple is immutable, whereas lists are mutable.
• Set: Iterable, changeable, and without duplicate elements, a Set is an unordered collection data type. The Set class in Python reflects the mathematical concept of a set.
• Dictionary: In Python, a dictionary is an ordered (since Py 3.7) [unordered (Py 3.6 & earlier)] collection of data values that may be used to store data values like a map. Unlike other Data Types that only contain a single value as an element, the dictionary holds a key: value pair. The dictionary includes a key-value pair to make it more efficient.

 

3. What is the lambda function in Python?

The lambda function is an anonymous function with a tiny size. A lambda function can take any number of parameters, but only one expression can be used. For example, 

addValue = lambda x : x + 5
print("Addition using Lambda Function")
print(f"5+5={addValue(5)}")

 

 

4. What is garbage collection?

Garbage collection (GC) is a memory management function in programming languages like C# and Java. One or more garbage collectors (GC engines) are included in a GC-enabled programming language, which automatically frees up memory space that has been allocated to objects that are no longer needed by the application. That application can then utilize the recovered memory space for future object allocations.

5. What is classLoader in Java?

The Classloader subsystem of the Java Virtual Machine is in charge of loading class files. The class loader loads a Java program first when we run it.

There are three varieties of classLoaders in Java,

• ClassLoader in Bootstrap
• Extension ClassLoader
• System or Application Classload

 

6. Define Marcos in C/C++.

In C/C++, macros are preprocessor constants that are changed at build time. As a result, a macro in a program is a named section of code. The compiler substitutes this identifier with the actual piece of code when it recognizes it. The drawback of macros is that they are code modifications rather than function calls. They also offer the benefit of saving time when substituting similar values.

 

7. What is structured programming?

This is one of the most common Apisero Interview questions, and they expect you to present your views on Structured Programming. A programming paradigm in which the control flow is organized is known as structured programming. A structure, such as conditional statements, loops, block structures, and subroutines, is a block with a set of rules and a specified control flow. Structured programming is required by nearly all programming paradigms, including the Object-Oriented Programming model.

 

8. Define struct in C programming language.

In C programming, a structure or struct is a user-defined data type that allows us to mix data objects of various kinds. A structure is essentially a representation of a record. The syntax of structs in C programming is given below,

struct Node{
   int value;
   Node *next;
};

 

9. What are unions in C programming?

In C, a union is a data type that allows you to store many data types in the same memory region. Even though a union might have a large number of members, only one of them is worth anything at any given moment. Unions allow you to reuse the same memory space for several jobs. The syntax of unions in C programming is given below,

union nameOfUnion
   {
      data member definition;
      data member definition;
      ...
      data member definition;
   };

 

An example of unions in C programming is given below:

union book
{
char nameOfBook[15];
    char nameOfBookAuthor[15];
    int priceOfBook;
};

 

10. What is the difference between finally, finalize, and final keyword?

Finally, finalize, and final are all keywords in the object-oriented programming language. Let us understand each one of them.

• final: final is a keyword and access modifier for restricting access to a class, method, or variable. With classes, methods, and variables, the final keyword is utilized.
• finally: Whether the exception occurs or not, the "finally" section in Java Exception Handling executes the necessary code. In exception handling, the final block is always linked to the try and catch block.
• finalize: finalize is a Java method that performs clean-up operations immediately before an object is garbage collected. With objects, the finalize() function is utilized.

 

11. What is polymorphism?

This Apisero Interview Question is used to test your fundamentals. Polymorphism is nothing but the fact that something can exist in more than one form. It is made up of two words: "poly" (meaning numerous) and "morph" (meaning shape). Its behavior changes according to the circumstances. This happens when we have a lot of classes that are connected through inheritance. Consider the car base class, which contains a carBrand function (). Volkswagen, Ferrari, BMW, and Audi are examples of derivative vehicle classes, each with its unique car design. There are two forms of polymorphism in C++,

• Compile Time Polymorphism or Static Polymorphism.
• Runtime Polymorphism or Dynamic Polymorphism.

 

12. What is virtual memory?

Virtual Memory is a type of storage allocation that allows you to address secondary memory as if it were the primary memory. Machine addresses, distinct from the addresses used by the memory system to denote virtual storage spaces, are automatically transformed from program-generated addresses. The computer system's addressing architecture limits virtual storage capacity. The quantity of secondary memory available is specified by the number of main storage sites rather than the actual number of primary storage locations.

 

13. Explain memory management in operating systems.

In a multiprogramming computer, the operating system takes up a small fraction of memory, while several programs use the remainder. The activity of splitting memory among many operations is known as memory management. Operating systems use memory management to coordinate operations between the main memory and the disc while performing a job. Memory management's primary purpose is to make the most of available memory.

14. What is socket programming?

Socket programming is a networking technology that allows two network nodes to interact. One socket (node) monitors traffic on a specific port at a given IP address while the other socket connects to it. The server creates the listener socket while the client is connected to it.

 

15. What is MultiThreading?

Multithreading is a system where several process threads are established to increase the system's computational performance. Threads are performed simultaneously in multithreading, and process generation in multithreading is done economically.

16. What is MultiProcessing?

A system with more than one or two processors is known as multiprocessing. CPUs are added to increase the system's computation performance in multiprocessing. Multiprocessing allows for the execution of several processes at the same time. Multiprocessing may be divided into two types,

• Symmetric Multiprocessing
• Asymmetric Multiprocessing 

 

17. What is a primary and a foreign key?

A primary key is employed to ensure that data in one column is unique. NULL or empty values are not allowed in this field. It's either an existing table field or one the database generates in a predetermined order. In contrast, a foreign key is a column or set of columns in a relational database table that connects data from two other tables. It's a column (or several columns) that refers to another table's column (usually the primary key).

 

20. List a few benefits of using the Database Management System.

The following are some of the benefits of a database management system:

• It is used to aid in the management of database redundancy.
• Ensures that data is consistent.
• Easily accessible.
• Backup and recovery services are available.
• Integrity limitations are enforced.
• It puts a stop to unauthorized access.
• Multiple user interfaces are provided.
• Due to the query usage, data extraction and processing are simple.

 

21. What is SLIP?

Serial Line Internet Protocol (SLIP) is an abbreviation for Serial Line Internet Protocol. It's a TCP/IP-based basic protocol used to communicate via serial ports and routers. They allow computers previously configured for direct communication to communicate with one another.

 

22. Mention the advantages and disadvantages of the star topology.

The spoke hub distribution idea is used in a star topology, a computer network. Each host in a star network is linked to the center hub. A single hub serves as a communication route in the most basic form. It is one of the most frequent computer network topologies. Some of the advantages of star topology are,

• It's simple to examine, set up, and change.
• The only nodes that have failed are those that have been impacted. Other nodes are still operational.
• High performance may be achieved with a limited number of nodes and minimal network traffic.
• Adding, uninstalling, and transferring devices is simple in a Star topology.

 

The disadvantages of star topology are,

• The linked nodes are deactivated if the hub or concentrator fails.
• The expense of setting up a star topology is significant.
• Buses may experience significant delays due to heavy network load.
• The hub's capacity determines performance.
• A damaged cable or a lack of adequate termination might bring the network offline.

 

23. What is Agile Methodology?

Agile software development is a set of iterative development approaches in which requirements and solutions emerge from cooperation amongst self-organizing cross-functional teams. Agile development's ultimate value is that it helps teams create products faster, with higher quality and predictability, and more flexibility to react to change.

 

24. What are microservices?

Microservices are architectural patterns commonly employed in current web systems with fragmented functionality. This implies that each service is a separate, modular procedure that may be introduced at any time. SOA is still used in lightweight architecture, which may benefit bigger businesses.

 

25. What is VPC in the Cloud?

A virtual private cloud (VPC) is a private cloud computing environment within a public cloud. A virtual private cloud (VPC) is a conceptually distinct component of a public cloud that offers a virtual private environment. A virtual private cloud (VPC), like a public cloud, is built on a shared infrastructure. A VPC, on the other hand, creates a barrier between cloud clients that share resources. This isolation can be achieved via a private IP subnet or a virtual local area network (VLAN).
