As someone with little technical experience in bitcoin has become a member of this forum, i want to know more about how bitcoin wallet is operated?
I think that the OP is asking specifically for practical info on how to use a bitcoin wallet. Although each wallet is slightly differently operated, and Charles-Tim already answered you with the most important fundamentals, I think the the best way to learn how bitcoin wallets are operated is making little transactions (to yourself maybe?) when fees are low. With a little more practice you can try signing them or (most importantly) coin control, but as a newbie don't be afraid to learn by doing, with small amounts of course, just in case .
