Point-to-Point Protocol (PPP) | Overview and Fundamentals

Previously, we saw SLIP, i.e. the Serial Line Internet Protocol, a simple data link layer protocol. Within this article, we’ll take a look at the Point-to-Point Protocol (PPP) another data link layer protocol as well, but it’s more powerful than the SLIP and a little complicated as well. The Point-to-Point Protocol was under development until…

Serial Line Internet Protocol (SLIP) | TCP/IP Data Link Layer

In this blog we will look at one of the link-layer protocols, i.e. Serial Line Internet Protocol, which is responsible for addressing the physical layer, Media Access Control (MAC) and also framing the datagrams obtained from the layer 3 protocol i.e. Internet Protocol (IP). The Physical Layer is the lowest layer on the OSI Reference…

TCP/IP Protocol Suite and Architecture

In this blog, we will learn about the TCP/IP Protocol Suite and TCP/IP Model Architecture. The Transmission Control Protocol ( TCP) is the transportation layer (layer 4 in the OSI Model) protocol which is responsible for link establishment and management. TCP enables efficient data transmission between processes in computer software. The OSI Model IP i.e.…

OSI Model: Networking Layers, Grouping, ‘N’ Notation, PDUs & SDUs

The OSI Reference Model is a valuable tool for explaining how the network functions, and also for describing the relationships between different networking technologies and protocols. In this blog, I will discuss what are the OSI Model layers, Notations used in the Model, and important data encapsulation concepts like Protocol Data Units (PDUs) and the…

Introduction To The Open Systems Interconnection (OSI) Reference Model

Networking is a vast topic and therefore a Model was introduced to understand the networking layer by layer. Models are useful because they help us understand difficult concepts and complicated systems. The OSI Reference Model facilitates the study, design, development, and rearrangement of networks by allowing them to be viewed as modular parts that communicate…

Network Performance Measurements: Bandwidth, Throughput & Latency

There are a number of terms that are used to refer to various aspects of network performance. Some of them might be familiar to you also. You will ofter see the use of these terms in any networking book or blog. Before going deep into the networking world, we should properly understand what these terms…

Circuit-Switching and Packet-Switching Networks

Devices are connected together using a network to allow the exchange of information between them. The path between devices over which the information will flow can be categorized into two namely circuit-switching and packet-switching Networks. Also read Introduction to Computer Network. Circuit-Switching In the circuit-switching networking method, a connection i.e circuit is set up between…

Introduction to Computer Network

We are living in an age where the network is everywhere and we use it regularly in the form of the INTERNET (The Ultimate Network), and the future will be more about the network. It is also possible, we might develop a massive network than the INTERNET. This makes the Computer Network an extremely important…
