It contained networking questions
A router is a networking device that forwards data packets between computer networks, while a switch is a networking device that connects devices within a network.
Router operates at the network layer of the OSI model
Switch operates at the data link layer of the OSI model
Router connects multiple networks together
Switch connects devices within the same network
Router uses IP addresses to route traffic
Switch uses MAC addre
Routing is the process of selecting the best path for network traffic to reach its destination.
Routing involves determining the optimal path for data packets to travel from the source to the destination.
Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.
Routing protocols like OSPF, BGP, and EIGRP are used to exchange routing information between routers.

MAC address is a unique identifier assigned to network interfaces for communications on a network.
MAC address stands for Media Access Control address
It is a 12-digit hexadecimal number (e.g. 00:1A:2B:3C:4D:5E)
Used to identify devices on a network at the data link layer of the OSI model
DHCP stands for Dynamic Host Configuration Protocol, used to automatically assign IP addresses to devices on a network.
Automatically assigns IP addresses to devices on a network
Helps in managing and organizing IP addresses efficiently
Reduces the need for manual configuration
Prevents IP address conflicts
Example: When a device connects to a network, DHCP assigns it an IP address from a pool of available addresses
A dangling pointer is a pointer that points to a memory location that has been deallocated or freed.
Dangling pointers can lead to crashes or unpredictable behavior in a program.
They can occur when a pointer is not updated after the memory it points to is freed.
Example: accessing a dangling pointer after freeing the memory it points to can result in a segmentation fault.
REST APIs are a set of rules and conventions for building and interacting with web services using HTTP methods.
REST stands for Representational State Transfer
Uses standard HTTP methods like GET, POST, PUT, DELETE
Data is transferred in JSON or XML format
Stateless communication between client and server
Example: Twitter API allows developers to access and interact with Twitter data

The OSI model has 7 layers that define how data is transmitted over a network.
Layer 1: Physical - deals with the physical connection of devices
Layer 2: Data Link - responsible for error-free transfer of data between devices
Layer 3: Network - handles routing of data between different networks
Layer 4: Transport - ensures reliable delivery of data between applications
Layer 5: Session - establishes and manages connections ...
Yes, there are seven layers in the OSI model.
The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has a specific function and communicates with the layers above and below it.
The OSI model is used to standardize communication between different computer systems.
Examples of protocols that operate at each layer include Ethernet at the Data Link layer and HTTP at t

Calculate the running median of a stream of numbers.
Use two heaps - a max heap for the smaller half of the numbers and a min heap for the larger half.
Keep the heaps balanced by ensuring the size difference is at most 1.
If the heaps are balanced, the median is the average of the top elements of the two heaps. Otherwise, it is the top element of the larger heap.
Trie is a tree data structure used for efficient retrieval of key-value pairs, commonly used in autocomplete and spell check applications.
