It is the protocol that allows the computer to communicate the email server for uploading and downloading the message whenever it is connected to the computer. POP has the ability to download all of the messages onto a local computer. So that the users can view all the downloaded messages on their system whenever they want to view in the absence of internet connection. POP has a small email server with some limited space that saves the money of the consumer or company.
