firewalls, ports, protocols

[gamiseta]

my current computer is a dell optiplex GX1 (its old) and i just got the below instructions but i got no idea how to do any of these on my computer (i dont know much about computers), i got no idea if i have a firewall and if i do i dont know what type, and i dont know how to configure the protocols and ports

can someone PLEASE help me with the following instructions -

please check that you have configured any firewall software such as Norton, Mcafee or Windows firewall to allow the software access to the Internet. This is usually done through settings/configuration under their allowed programs list. For more information on how to do this please refer to the firewall provider's user manual or your system administrator. The same would apply if you are going through a proxy server.

For more complicated proxy servers/firewalls you need to configure the exact ports and protocols allowed. Our download software uses these protocols (HTTP, HTTPS, TCP) and ports (TCP):

5700-5710, 5720-5724, 5750-5759, and 5760-5769

thanks alot for any help
