Summarize the below scenario

Look at the bank, the tellers are like a thread and they operate concurrently.

Each thread has a line of customers this line acts like a que. Now what time of que. Now when a teller works with a customer how is the tread working (block, ect).

Now there must be a scheduler - who is that?

Head teller? So look at the book and for each piece like thread, queues, process, communication algorithms, etc then I want you to find each piece in the book to a person in the bank.

Expand the example to cover the loan officers. They do have people waiting for them acting like a queue.

But what makes there queue different.

Maybe be appoint rather than first one, first server. What type of queue has appointments?
