Additional information in cable television and specifications

Hello!
I want to know what is the purpose and functions of dish? How does it works? What do you mean by “egress?” How does it affect cable television reception? What are the main reason why we have “egress?” What is F-Connector and what is the use of it? Is it an old connector? Do we have a upgraded version of this connector? What does HFC stands for and what is the proper use of it? What is forward path? What is matching transformer and what is a jumper?
Thank you!
