Speaking in a pre-recorded segment of Radio 5 Live's Emma Barnett Show - which she will guest edit - Camilla said: "I'm ashamed to say that I really hated the internet. I didn't understand it and I thought, 'What's the point of this?'.
"Since lockdown, it's been so brilliant because I've been able to communicate with family, my children, my friends.
"But it's also taught, children ... otherwise children who aren't at school what would they have done without it?"
Camilla has been missing her grandchildren and "shall look forward to the day" she can finally hug them again.
She said: "You're so excited because you haven't seen them for three-and-a-half months ... Your first reaction is to run up and hug them, and you have to sort of put up your hands. It's a very odd feeling."
Camilla has made the most of not having to get dressed up while she's been out of the public eye and not undertaking in-person official duties but is concerned she'll be very reluctant to stop wearing her jeans when the time comes.
She said: "It will be very hard to get out of them again. I think you get into a sort of way of life, don't you?"
