Mr. Clarkson Talks About... Protocols and Port Numbers

[TheMatteoDV]

POP stands for Post Office Protocol, not needed as you said but it makes sense.

@TheMatteoDV It does - I meant to add that in the edit, but forgot. Cheers for clearing that up.

@mwclarkson No problem I was doing revision for my exam at 1:40 today and started watching your videos which are a really good recap, thanks!

When I try the command prompt thing: "telnet is not recognized as an internal or external commend, operable program or batch file"

[mwclarkson]

@mint301 Go to Control Panel >> Programs&Features >> Turn Windows features on or off >> Telnet Client.... You should find the option to install telnet or switch it on.

(Google is your friend :-D)

Or better still, use a Mac or Linux machine...
