SSL can be used on many ports; for web traffic, the common port is 443.
they are both ports of entry.
web servers us port 80 to serve websites by default but they can be reconfigured to serve on different ports
Port 80 is primarily used for HTTP traffic, allowing web browsers to communicate with web servers and retrieve web pages. Port 25 is traditionally used for SMTP (Simple Mail Transfer Protocol), which is responsible for sending and routing emails between mail servers. Both ports are essential for their respective functions in web browsing and email transmission.
They both have "web" in it :)
Many modern laptops don't have a serial port at all. The most common serial ports on desktop computers were the old style of mouse ports that look like this picture: http://i32.tinypic.com/29vtir.jpg
they are all ports
Yes, we can host multiple web sites on single web server and only one FTP server per IP address. They just use different ports.
A website that shows how to open ports in a firewall is the Sever Fault website. Another website that shows how to open ports in a firewall is the Windows website.
When two programs on the same computer want to access the internet, they will each use a different port. For example, if you are chatting on AIM and browsing the web at the same time, web traffic will go through port 80 and AIM traffic will go through port 5190. That way when data comes back to the computer, it can be directed either to AIM (if it comes in on 5190) or the web browser (if it comes into port 80). If you are choosing a port manually for some reason, it doesn't usually matter what you choose as long as that port number is not in use by another program. Pick a big random number and you are safe. -DJ Craig
"Surfing the web" or "web browsing" or "Google it"
Multiplexing the data of diverse application over a common channel can be a good thing.
