title: How to try out HTTP, FTP, SMTP etc. application protocols
body: <p>I am reading <a href="https://rads.stackoverflow.com/amzn/click/com/B005GLUZ2Q" rel="nofollow noreferrer" rel="nofollow noreferrer">Computer Networking: A Top-Down Approach 5th (fifth) edition</a>. I have reached chapter two and I wonder if it is possible to actually try out the different application protocols by writing the requests etc? I am using Windows if that matter if you need a tool for doing that, and if I need a tool, what does the tool do behind the scenes for connecting?</p>
