TCP and UDP : A Guide to Network Communication Protocols

Image
In the world of computer networks, two fundamental protocols play a vital role in facilitating communication: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). These protocols govern how data is transmitted and received across networks. In this blog post, we will delve into the basics of TCP and UDP, demystifying their functionality, differences, and use cases. By the end, you will have a clear understanding of these protocols and their importance in network communication. Transmission Control Protocol TCP: The Reliable Connection-oriented Protocol: TCP is a connection-oriented protocol that ensures reliable delivery of data. Think of it as a conversation between two individuals where messages are exchanged and acknowledged to ensure the information arrives intact. TCP establishes a connection between a sender and receiver before data transmission, verifying that packets are delivered in the correct order and without errors. TCP's features include: a. Reliabilit...

Demystifying DNS: Understanding the Network Protocol

In today's interconnected world, the Domain Name System (DNS) plays a vital role in enabling the seamless flow of information across the internet. While it might seem complex at first, understanding DNS is crucial for anyone interested in networks and cybersecurity. In this blog post, we will delve into the fundamentals of DNS, demystify its inner workings, and explore its significance in maintaining a robust and efficient network infrastructure. What is DNS? DNS, short for Domain Name System, is a hierarchical decentralized naming system that translates human-readable domain names (such as www.example.com) into machine-readable IP addresses (such as 192.0.2.1). It acts as the phone book of the internet, linking domain names to their corresponding IP addresses. How DNS Works: DNS Resolution Process: When a user enters a domain name in their web browser, the DNS resolution process begins: The user's device sends a DNS query to a DNS resolver (usually provided by the Internet Ser...
