• 13:02, 1 August 2023 Andrew talk contribs created page OPS345 Lab 7 Newversion (Created page with "= Email services components = Originally there was only one "email" protocol: SMTP. It was designed to address, route, and receive messages for a destination user on a destination server. Later an extra couple of protocols (POP3 and IMAP) were developed so that people wouldn't have to read their email on the command-line on the SMTP server. Now there are many components, making a powerful, reliable, but complex system. Here's a simplified diagram of what typically happen...")

The cyphertext created by a good encryption algorithm is impossible (or, for weak algorithms: at least impractical) to decrypt (covert back into plain text) without a key. You've been using public key cryptography for your entire life (unless you were born before the 1990s). And you've been setting up public key cryptograph...")

Computers on the internet can only communicate with each other using IP addresses. But people aren't very good at remembering long strings of numbers (up to 12 digits for ipv4) or even longer strings of numbers and characters mixed (24 characters for ipv6). Therefore DNS is a critical part of the internet infrastructure, and just about everyone who has a website needs to do so...")

Only people in the Matrix can look at a stream of binary data and see pictures.
