Introducing computing and IT

1 Computers: from rarity to ubiquity


This first section of the course should take you around one hour to complete.

The theme of this section is the development of digital technologies, from the physically large and highly expensive equipment of the 1950s to the omnipresent networks and computer-based devices which our digital lives are founded on today. This section will:

  • compare the development of the computer to the development of the telephone
  • describe some of the digital technologies that form an integral part of many people’s lives
  • introduce the term information society.
