Routers connect multiple networks together, while switches connect devices within a single network.
Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).
Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.
Routers determine the best path for data packets based on routing tables, whi...
A MAC address is a unique identifier assigned to network interfaces for communications on a network.
MAC stands for Media Access Control
MAC addresses are 48 bits long
They are usually represented in hexadecimal format, like 00:1A:2B:3C:4D:5E
There are 5 types of IP classes: A, B, C, D, and E.
Class A: Used for large networks with over 16 million hosts. Example: 10.0.0.0
Class B: Used for medium-sized networks with up to 65,000 hosts. Example: 172.16.0.0
Class C: Used for small networks with up to 254 hosts. Example: 192.168.0.0
Class D: Reserved for multicast addresses. Example: 224.0.0.0
Class E: Reserved for experimental use. Example: 240.0.0.0

Inheritance: creating new classes from existing ones
Polymorphism: using a single interface to represent multiple types
Abstraction: hiding implementation details from the user
Examples: class, object, inheritance, polymorphism, encapsulation

Method overloading is having multiple methods with the same name but different parameters. Method overriding is having a method in a subclass with the same name and parameters as a method in its superclass.
Method overloading is done within the same class while method overriding is done in different classes (subclass and superclass).
Method overloading is achieved by changing the number of parameters or the data type of ...
The parent class of all classes in Java is the Object class.
All classes in Java implicitly extend the Object class.
The Object class provides basic methods such as toString(), equals(), and hashCode().
Any class can override these methods to provide custom implementations.
Example: public class MyClass extends Object { ... }
Example: Object obj = new MyClass();
SQL databases are relational and use structured query language, while NoSQL databases are non-relational and use various data models.
SQL databases are based on a fixed schema, while NoSQL databases are schema-less.
SQL databases use tables to store data, while NoSQL databases use various data models like key-value, document, columnar, or graph.
SQL databases are better suited for complex queries and structured data, whil...
