Problems solved by technology

For example, a mail server may have to reject important and / or desired e-mails when the mail server's storage capacity is filled to the maximum with unwanted e-mails containing advertisements
Additionally, thin client systems such as set-top boxes, PDAs, network computers, and pagers all have limited storage capacity
In any of these systems, unwanted e-mails take a user's limited resources
Additionally, typical users waste time by downloading large amounts of useless advertising information
