In our discussion of the IP protocol, the reader might have noticed that there are many desirable features that the IP protocol does not have. Suppose for instance that we are building an application that needs to transmit data in a stream oriented way - this could be a video, an MP3 file or a … Continue reading Networking basics – the TCP protocol
When I started this blog, my intention was to document my own attempts to learn and understand some of the topics at the intersection of computer science, physics and mathematics that have the potential to change the world in which we work and live. After spending some time with one of these topics - machine … Continue reading Quantum computing
In the last post in this series, we have covered the basics of the IP protocol - the layout of a network message and the process of fragmentation. However, there is one point which we have not yet discussed. Assume that an application or operating system has actually assembled a message and applied fragmentation so … Continue reading Networking basics – IP routing and the ARP protocol
In the previous post in my networking series, we have looked in detail at the Ethernet protocol. We now understand how two machines can communicate via Ethernet frames. We have also seen that an Ethernet frame consists of an Ethernet header and some payload which can be used to transmit data using higher level protocols. … Continue reading Networking basics – IP
In the previous post in this series, we have looked at the layered architecture of a typical network stack. In this post, we will dive into the lowest layer of a typical TCP/IP implementation - the Ethernet protocol. The term Ethernet originally refers to a set of standards initially developed in the seventies by Xerox … Continue reading Networking basics – Ethernet
Recently, I picked up an old project of mine - implementing a Unix like operating kernel from scratch. I will post more on this later, but one of the first things I stumbled across when browsing my old code and my old documentation was the networking stack. I used this as an opportunity to refresh … Continue reading Networking basics – the layered networking model
Its been a few days since I started to play with Paperspace, and I have come across a couple of interesting features that the platform has - enough for a second post on this topic. First, GIT integration. Recall that the usual process is to zip the current working directory and submit the resulting file … Continue reading More on Paperspace Gradient
