11/12/2022 0 Comments Using zenmap![]() ![]() It determines how to break application data into packets that networks can deliver, sends packets to and accepts packets from the network layer, manages flow control and handles re-transmission of dropped or garbled packets, and acknowledges all packets that arrive. ![]() TCP is a connection-oriented protocol, which means a connection is established and maintained until the application programs at each end have finished exchanging messages. If you want to learn the philosophy behind TCP & need a book to read on weekends check out this masterpiece dated September 1981! And that's what is fascinating about networks, the protocols we are using today are exactly the same as were defined decades ago with very few alterations, if at all. One of the most prominent protocols in this layer is TCP. In the attempt to keep this post away from surpassing its limits to be called a post, let's discuss briefly one of these layers, L4 => Transport layer These layers are responsible for handling everything that happens behind the scenes when you make that new network connection (say, open a new tab on your browser and go to ), and in here are a bunch of protocols. Sneak peek into (somewhat applicable history):Įven if you have bunked the Computer Networks lectures in your school/college, if you are remotely associated with engineering, there are high chances you'd have heard of this term. There are just way too many exciting things in this single concept! So, let's begin with the basics: The initial things that'll get you started with learning more about the networks and getting hang of the awesome tool: NMAP Networks is a very broad concept to understand and explore. If you are not sure about the majority of the questions asked above, congrats, you have landed on the correct post! Please follow along. How are you doing? More so, how is your internet doing? What about LAN? Are you exchanging traffic with domains you'd not want to? Are there any open ports on your network that can be attacked? Most importantly (and somewhat not related to the post) have you changed your router's default credentials? Here's to learning basics of networking and an awesome tool called NMAP! ![]()
