To "announce" something means to let people know about it publically. Companies often "announce" things like new products, changes in their policies, good news about their sales, and so on:
The company announced plans to close factories and drop unprofitable product lines.
Companies can "announce" things in writing (with a "press release") or in a public presentation (a "press conference")
You use "going to ___" to talk about what will happen in the future. "Going to ___" is more natural than "will" for most situations where you're expressing someone's plans to do something:
They're going to meet us at the airport.
I'm just going to stay home and relax this weekend.
If you want to give or sell something to people, you first need to tell people that you will give it to them or ask if they want it. This is called "offering" something.
You usually use the word "offer" when the things you're giving or selling are good or exciting:
We're offering 20% off everything in the store, this weekend only.
"Internet access" is the phrase that we use to describe the ability to connect to the Internet. It also explains the services that people use to connect to the Internet:
How much do you pay per month for Internet access in France?
A store or restaurant company that has lots of stores in different places is called a "chain". Each store in the chain is called a "location". For example a representative from such a company could say:
We have over 300 locations across the U.S. and Canada.
You use the word "location" in this way when you're talking about the company as a business. In everyday life, when you want to talk about one store or restaurant in a chain, you just call it a "store" or a "restaurant".
