IMAP keeps email on an email server by default

Explanation:

IMAP by default can keep the email in the server, this is so helpful because we can get the email in any location, this is the difference with POP3.

POP3 stores the email in the server, but when we get the email with our application, the server deletes all the information, although we can do a configuration in the settings called Keep email on the server.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
