Can you mine bitcoins with an intermittent Internet connection? I've got a very precise question and this is not a dupe of:

Does Bitcoin rely on the internet?

My question boils down to: when you mine bitcoins, how "often" does the computer/hardware doing the mining need to connect to the Internet?

However to better explain what I mean by that question, here are a few sub-questions.

When a computer is mining, when is the result of the mining accepted/confirmed?

For example, after the computer received sufficient information to start mining, when will that information not be sufficient anymore to continue mining?  In other words: when will the computer need to have Internet access so that it can continue mining? 1 picosecond? 1 nanosecond? 1 ms? 1 second? 1 minute? 1 hour? 1 day?

What happens if some computation is done on my mining computer, but then Internet connection is off? Is the result "lost" and if that result is lost, after how much time is it lost? 1 picosecond? 1 nanosecond? 1 ms? 1 minute? 1 hour? 1 day?

It may look like a "stupid" question but it would really help me better understand how BitCoin works...

(as I'm new here [but certainly not new on the SE network] I don't know which tag to use: thanks for retagging accordingly if needed)
Assuming you are mining on a pool, your miner needs to receive and send work (shares) every few seconds, with the exact frequency depending on your hashing speed and the difficulty of the shares.

For example, my ASIC sends and receives shares at least once every 20 seconds or so.

So you need a reliable network connection if you don't want your miner to sit idle. This is the same reason why you normally configure the miner to have fall-back pool servers in case the main pool server goes down.
