Operating Systems : Coursework 2 : Essay

  • Write an essay of 2000-3000 words on the topic of Operating Systems for mobile handheld devices such as PDAs (Personal Digital Assistants), Organisers and Pocket PCs. Such gadgets offer functions such as calendar/diary organising, telephone/fax and networking features, games etc. amongst many other things. They have a small LCD display, sometimes colour, and often use a stylus for touch-screen interaction rather than a keyboard. Behind the user-level applications is an operating system. Your essay should be concerned with technical details of these operating systems, their organisation and the facilities they provide for application-level software. We are not concerned with the applications themselves in any detail.
  • A number of manufacturers make these devices including Palm with their Palm III, V and VII series, HP with its Jornada series, Psion, Casio’s Cassiopeia, Handspring’s Visor etc. Some use their own proprietary operating systems and some use more widely available ones. For instance, Palm and a number of other manufacturers use PalmOS, Psion use their own EPOC system and the rest tend to use Microsoft’s Windows CE.
  • Write an overview of each of these three operating systems (and any others you may come across) together with a comparison of their approaches. This should be followed by a description of one of then in more technical detail.
  • Your main source of information will be the Web. There are also one or two books (on Windows CE, in particular). Include a list of references to the sources of information you have used, including URLs where appropriate. Your main difficulty is likely to be separating technical information from sales and marketing dross.
  • Your essay should be word-processed, not hand-written, and a hard-copy version handed in to the Informatics Teaching Office on or before the deadline.
  • Deadline : End of Term, Friday 15th December
