Understanding Routing in Computer Networks: From Basics to Advanced Protocols

Understanding Routing in Computer Networks: From Basics to Advanced Protocols

Comments 5 Comments

Think about how you use Google Maps or a delivery app every day. When you request directions, it doesn’t direct you blindly; it calculates the best route considering roads, traffic, and time. Similarly, in computer networks, packets need smart decisions on where to go and how to get there efficiently. Just like your map app reroutes when a road closes, routers dynamically reroute data to keep it moving smoothly. The complete tutorial on Computer Networks can be explored here. “Routing…

Introduction to ICMP Protocol

Introduction to ICMP Protocol

Comments 8 Comments

The Internet Control Message Protocol (ICMP) is an integral part of the Internet Protocol (IP) suite, which plays a crucial role in network communication. Although it is not used for data transmission like protocols such as TCP or UDP, ICMP serves an important function in diagnosing network issues and ensuring that data is delivered efficiently. ICMP is often used by network devices, including routers and hosts, to send error messages and operational information, helping maintain healthy network communication. You can…

Understanding IPv6 Addressing

Understanding IPv6 Addressing

Comments 17 Comments

IPv6, or Internet Protocol version 6, is the most recent version of the Internet Protocol, which serves as the foundation for communication on the Internet. It was developed to overcome limitations posed by its predecessor, IPv4 (Internet Protocol version 4), and to address the growing needs of the evolving internet. IPv6 is a 128-bit long address standard, designed to provide a vastly expanded address space compared to the 32-bit addresses used in IPv4. IPv6 addresses are expressed as eight groups…

Distance Vector and State Link Routing Protocols

Distance Vector and State Link Routing Protocols

Comments 17 Comments

Routing protocols are fundamental to network communication, and two prominent categories are Distance Vector and State Link protocols. Distance Vector protocols, exemplified by Routing Information Protocol (RIP), make routing decisions based on cumulative distances to destinations, conveyed through periodic updates. They employ algorithms like Bellman-Ford and rely on routing tables to determine the best paths. However, the convergence time can be slower due to periodic updates, and scalability may be challenging in large networks. This page will not be updated…

Error Detection and Correction in Data Communication

Error Detection and Correction in Data Communication

Comments 15 Comments

Before going toward error detection and correction, let bit explore the byte stuffing which accrues in packet transmission. What is Byte Stuffing? Byte stuffing is a data encoding technique used in computer networking to ensure the reliable transmission of information, particularly in the context of data framing. It involves the insertion of special control characters, known as “flag” or “escape” characters, into the data stream to distinguish them from the actual data. The primary purpose of byte stuffing is to…

Multiple Access Techniques (Channelization) in Data Communication

Comments 3 Comments

In modern communication systems, multiple devices often need to share the same communication channel. This is where Multiple Access Techniques (MATs) come into play. They allow multiple users to efficiently use a limited amount of bandwidth simultaneously. These techniques are crucial, especially in wireless networks, where many users are trying to connect without causing interference. Visit the detailed tutorial on computer networks here. Common Multiple Access Techniques Here’s a breakdown of some of the most common multiple-access techniques: Frequency Division…

Circuit Switching and Packet Switching in Computer Networks

Circuit Switching and Packet Switching in Computer Networks

Comments 1 Comment

Circuit switching and packet switching represent two distinct paradigms in data communication. Circuit switching creates a dedicated communication path for the entire duration of a conversation, ensuring a continuous link between devices. In contrast, packet switching involves breaking data into independent packets, allowing for flexible routing and efficient resource utilization across the network. You can also visit a detailed tutorial on Data Communication and Computer Networks here. What is Circuit Switching? Circuit switching is a communication method where a dedicated…

Ethernet and Its Technology

Ethernet and Its Technology

Comments 1 Comment

Ethernet is a widely used and standardized technology for wired local area networks (LANs) that facilitates the transmission of data between devices within a localized network. It defines the rules and protocols for how data packets should be formatted, transmitted, and received over physical network connections, typically using Ethernet cables with RJ-45 connectors. The detailed tutorial on Computer Networks can be accessed here. Have you ever plugged a LAN cable into your laptop and instantly connected to the internet? That’s…
