`
`This invention makes it possible for a customer computer to
`connect to an online service provider computer by phone,
`Internet, or other method, pay a fee to said service provider,
`and obtain additional processing and storage resources for
`the customer's computer. The resources can take the form of
`virtual storage and processing capabilities. These capabili(cid:173)
`ties give the customer computer what appears to be addi(cid:173)
`tional local processing power and/or additional local
`storage, this storage possibly including preloaded software
`and/or data.
`
`The additional resources made available to the customer
`computer can be used either to enhance the customers' local
`needs (such as access to virtual storage for additional disk
`space, or access to a more powerful processor of similar type
`for program execution), or these additional resources can be
`used by the customer computer to support services on-line
`that otherwise would be unavailable, impractical, or unaf(cid:173)
`fordable. Examples of services include software and infor(cid:173)
`mation rental, sales, and release update services, anti-viral
`services, backup and recovery services, and diagnostic and
`repair services, to name a few.
