91.308 Assignment 1: Intro and OS Mini-Research Project

1. Read Chapter 1 of Tanenbaum (pages 1–67).

2. Prepare written answers for the following questions at the end of Chapter 1:
   • Question 7, cost of video RAM
   • Question 8, kernel mode
   • Question 23, client-server model

   These written answers should be handed in in class on the assignment due date.

3. Research information about an obsolete/unusual/modern/obscure computer platform, and describe key properties of its operating system.

   Each student must choose a different machine or platform. This will be ensured with the following procedure:

   1. Log into the class's discussion board, using the ikonboard link from the class home page. Create an account for yourself if necessary.
   2. Choose your machine/platform.
   3. Go to the ikonboard discussion board and look through the topic entitled Reserve your OS here. Make sure your machine is not taken. If it is, go to step 2 and try again.
   4. Make a posting to this same board, reserving your selection.
   5. Perform the research.
   6. Post your writeup under the topic entitled Post your OS reports here.

   Your report should be about 1 page long, and include details such as:

   • Years that the computer was in use.
   • Was it multi-user or single-user? Single-tasking or multi-tasking?
   • What peripherals (disk, printer, input, screen) did the system have?
   • What was the primary application/purpose?
   • Special features of the operating system.

   Also – very important – make sure to give full citations and URLs to all source material that you used in preparing the report.

   The report should be posted under the discussion topic “Post your OS reports here” by the end of class on the assignment's due date.
