In a series of informative articles, I will introduce all issues associated with the World Wide Web from the employment perspective. Here I begin with the 30-year evolution of WWW to preface the series. It all started with a single processor exclusively used by a single user. The current user delivered programs through peripherals. Mainframe computing A single huge computer used by many users.
Every user has a committed terminal, but the actual processing is done on the mainframe computer.
Complex operating systems were needed for sharing resources. Relatively cheap computers used exclusively by one user. The stand-alone model can describe today s home users. Network computing Mainframe becomes a bottleneck as more users rely on computers to do their jobs. Terminals are substituted with PCs and workstations.
