Introduction                        This is the second blog in the networking fundamentals series in which we try to specify the what-abouts of TCP/IP Protocol suite. I believe this will be the most commonly used protocol on the internet. While it may not directly be used for communication, it is encapsulated under other protocols like HTTP(s), FTP and SFTP, etc., We will try to cover the typical use of TCP/IP and compare the same with OSI Model.                         Let's get started with details about TCP/IP. TCP is known as Transmission Control Protocol, which is connection-oriented protocol unlike our friend UDP. This protocol relies on sequential data transfer and guarantees the delivery. While these may seem an essential thing, this adds a certain amount of complexity to the implementation as well... Transmission Protocol           ...

 Introduction                                  The invention of the Computer has been one of the most significant technological advancements of the past century. From the early days of mainframe systems to modern laptops and smartphones, computers have become an integral part of our daily lives. In this blog post, we will explore the positive impact of computers on humans, their pros and cons, the benefits of computer technology for humans, and the latest updates in computer technology that have shaped our lives.  Benefits of Computers for Humans:                       Computers changed the whole system of our workstyle, communication methods, and interaction ways with the world. They have made our lives easier and more efficient in numerous ways.  Digitalized Professional Lives                 ...

    OSI   Reference Model | 7 layers Introduction of OSI Reference Model The OSI Model was developed by the ISO (International Organization for Standardization). OSI stands for Open System Interconnection. There are seven layers in this model. OSI model is developed after the TCP/IP Model.  Physical Layer The physical Layer is the lowest layer of the OSI Model. It coordinates the function required to transmit a bit stream over a communication channel. The physical layer is responsible for the movements of individual bits from one hop (node) to the next. It deals with the electric and mechanic specification interface and transmission media.  Data - Link Layer The Data-Link layer transmits frames from one node to the next. It transforms the physical layer into a reliable link making it an error-free link to the upper layer. Network Layer The Network Layer is responsible for the delivery of packets from the source to the destination. It provides host-to-host delive...
