Exploring C++, Data Structures, and HTML

What is the purpose of an operating system?

• The purpose of an operating system is to manage computer resources and provide a user interface for interaction with the hardware.

• To provide internet connectivity

• To increase battery life

• To enhance graphics performance

Explain the difference between a process and a thread in C++.

• A thread is a separate execution unit with its own memory, while a process shares memory with threads.

• A process is a thread that runs in parallel with other threads.

• A process is an independent execution unit with its own memory, while a thread is a lightweight unit of a process that shares memory with other threads.

• A process and a thread are the same, both representing a single execution path.

What is a binary tree and how is it structured?

• A binary tree is a hierarchical data structure where each node has at most two children.

• A binary tree can have any number of children for each node.

• A binary tree is a flat data structure with no hierarchical relationships.

• A binary tree is a linear data structure with nodes arranged in a single line.

Describe the advantages of using linked lists over arrays.

• Advantages of linked lists over arrays include dynamic size, efficient insertions/deletions, and ease of implementing complex data structures.

• Simpler implementation of basic data structures

• Fixed size and memory allocation

• Faster access to elements by index

What is the role of the kernel in an operating system?

• The kernel stores all user data and files.

• The kernel provides internet connectivity for applications.

• The kernel manages system resources and facilitates communication between hardware and software.

• The kernel is responsible for user interface design.

How do you implement a stack using a linked list in C++?

• Define a Node structure, create a Stack class with push, pop, and isEmpty methods to manage the stack.

• Implement the stack using a queue

• Use an array to implement the stack

• Create a class with only a push method

What are the different types of HTML elements?

• Text elements

• Image elements

• Video elements

• Block-level elements, Inline elements, Self-closing elements, Form elements, Semantic elements.

Explain the concept of memory management in operating systems.

• Memory management is the process of storing data on hard drives.

• Memory management is solely about increasing the speed of the CPU.

• Memory management is the process of controlling and coordinating computer memory, ensuring efficient allocation and deallocation of memory resources for processes.

• Memory management refers to the physical arrangement of computer hardware.

What is a doubly linked list and how does it differ from a singly linked list?

• A doubly linked list can only be traversed from the last node to the first node.

• A singly linked list has two pointers per node, while a doubly linked list has one.

• A doubly linked list is more memory efficient than a singly linked list.

• A doubly linked list allows traversal in both directions, while a singly linked list only allows traversal in one direction.

What is full form of HTML

• Hyper Tone Medium Language

• Hi Text Markup Language

• Hyper Text Markup Language

• None of the above
