Evolution of Linux computing and its implications

Thirty years ago, computers were so physically immense that they often had to have rooms and buildings built with the purpose to accommodate them. Yet even with such bulky restrictions, the main problem posed by computers at the time was that each one had a different, unique operating system. Software was mainly created or customised to suit the specific needs of individual computers and inter-compatibility between operating systems had yet to be considered nor developed. Understandably, computers at the time were extremely costly items, were temperamental, and more often than not caused headaches for both users and system administrators alike.
