Introduction to Routing in Computer Networks

Introduction to Routing in Computer Networks

Comments 14 Comments

Routing is an important function in computer networking that involves directing data packets from one device to another across a network. It ensures that information reaches its destination efficiently and accurately. Routers are the key devices responsible for making routing decisions in a network. A detailed tutorial can be found here. This page will not be updated further; therefore, visit this one. Routing is divided into two categories. Understanding Static Routing Static routing is a routing method where network administrators…

CIDR (Classless Inter-Domain Routing) and VLSM (Variable Length Subnet Masking)

CIDR (Classless Inter-Domain Routing) and VLSM (Variable Length Subnet Masking)

Comments 142 Comments

In the domain of networking, two pivotal concepts revolutionized the way we allocate and manage IP addresses: CIDR (Classless Inter-Domain Routing) and VLSM (Variable Length Subnet Masking). CIDR emerged as a response to the limitations of traditional IP addressing, introducing a more flexible and efficient approach to representing IP address ranges. On the other hand, VLSM, a crucial extension of CIDR, empowers network administrators with the ability to optimize subnetting by allowing variable-length subnet masks. Together, CIDR and VLSM have…

Packet and Frames in Computer Networks

Packet and Frames in Computer Networks

Comments 23 Comments

Packets, frames, and error detection are fundamental concepts in computer networking and data communication. These terms are used to describe how data is structured, packaged, and transmitted in a network, as well as how errors in data transmission are identified and handled. Let’s explore these concepts: What are Packets? A packet is a small unit of data that is transmitted over a network. It typically includes both the data to be sent and control information, such as the source and…

Basics of Internet Protocol (IP) AND IP Addressing

Comments 2 Comments

The Internet Protocol (IP) is a fundamental set of rules and conventions that define how data is transmitted and routed over the Internet. It is the backbone of modern networking, ensuring that every piece of data finds its correct destination, whether between two computers in a local lab or between continents. Visit the detailed course on Computer Networks for more tutorials and visual explanations. Introduction to the Internet Protocol (IP) The Internet Protocol provides the addressing and routing system that…

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

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

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…
