Hypertext Transfer Protocol - used for communication between web server and web browserport 80
Hypertext Transfer Protocol over Secure Sockets Layer - used to make a secure connectionport 443
Internet Message Access Protocol - protocol with a store-and-forward capability that allows messages to be stored on an email server instead of downloaded to the client.port 143
127.0.0.1Used to check that TCP/IP is functioning properly locally without checking the status of the network.
Network Address Translation - used to translate between public and private addresses. It allows the NAT server to be used as a proxy between them so all hosts on an internal network can be configured with private addresses.ICS-Internet Connection Sharing is included for use on Small Home Networks
Post Office Protocol - used for receiving email from an SMTP server.Port 110
Any server that acts on behalf of another in order to obtain network access, usually to the internet. Most are also NAT servers, but don't have to be. ISA- Microsoft Internet Security and Acceleration Server is one of the most well known proxy servers
