The Basic Networking concepts

Hi everyone! Welcome to my article on Basic Networking Concepts. Let’s dive in!

IP Addresses

• Definition: An IP address (Internet Protocol address) is a unique identifier for a device on a network. It allows devices to communicate with each other over the internet or local networks.
• Types:

— IPv4: Composed of four octets (e.g., 192.168.0.1).

— IPv6: Composed of eight groups of hexadecimal numbers (e.g., 2001:db8::ff00:42:8329).

DNS (Domain Name System)

• Definition: DNS translates human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network.
• Example: When you type www.google.com into your browser, DNS resolves this to an IP address like 142.250.190.78.

HTTP/HTTPS

• HTTP (Hypertext Transfer Protocol): The protocol used for transferring web pages over the internet. It is not secure by itself.
• HTTPS (Hypertext Transfer Protocol Secure): An extension of HTTP that uses encryption (TLS/SSL) to secure data transmitted between the client and server.

TCP/IP (Transmission Control Protocol/Internet Protocol)

• TCP: Ensures reliable data transmission by establishing a connection between sender and receiver and checking that all data packets are received correctly.
• IP: Handles addressing and routing of packets to ensure they reach the correct destination.
• Example: When you send an email, TCP ensures that the email is sent correctly and completely, while IP ensures that it reaches the mail server.
