Understanding IPv6 Addressing

Understanding IPv6 Addressing

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

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. Distance Vector Protocol A Distance Vector…

Circuit Switching and Packet Switching in Computer Networks

Circuit Switching and Packet Switching in Computer Networks

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 detailed tutorial on Data Communication and Computer Networks here. What is Circuit Switching? Circuit switching is a communication method where a dedicated communication…

Error Detection and Correction in Data Communication

Error Detection and Correction in Data Communication

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…

Ethernet and Its Technology

Ethernet and Its Technology

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. What Are LAN Cables? LAN cables, short for Local Area Network cables, are physical cables or wires used to connect devices within a localized network. Types of…
