Whereas previous generations ordered products from mail order retailers and expected to wait several weeks as their order was delivered to the retailer via postal service, was processed and filled, and then shipped back; digital generations expect to place an order on a web site and receive the product within a day or two. Whereas previous generations expected to take a test in class and have it returned graded within a day or two, the digital generations expect to take a test online and see the results immediately. Whereas previous generations called friends on the telephone and expected them to call back within a few hours if they were not available, members of the digital generations expect their friends to carry cell phones and answer their messages (phone calls or text messages) within seconds.
