Where before we would have actually had to teach two running programs to " talk " to each other in some intermediate language ( called a protocol in the networking world ) if we wanted them to exchange information , now when one program might need to get some information from another , on another computer , it need merely invoke a method on that other system ( specifically , in our case , on another Java Virtual Machine ) and wait for the returned result . There are times when a user might need to clear out his or her mailbox in order to conserve disk space . Flexible tenure is also a useful option where , for example , an older person might need to release equity to pay for care or major repairs . These questions must be answered for each individual user job role or responsibility you plan to support on the desktop - - this means that your organization might need to compile separate sets of answers for clerical staff , help desk workers , administrators , managers , accountants , and so forth .
