A Course Resource and Portal to Peer Blogs
The key to using memory most efficiently is virtual memory management. Consider both Windows and UNIX operating systems. Compare and contrast how each implements virtual memory. Describe how each one handles page faults, working sets, and page sizes, and how it reconciles thrashing issues. Cite your sources (URLs), and remember to include your name in your comment.
The history and culture of computing is an essential part of your education in the discipline. Research the origins of the term "algorithm," summarize what you found, and then post the URL of the site where you found the information as well as your name. This is an extra credit, optional exercise!
The first element of Operating systems we study is memory. The textbook is limited to those elements of memory that were available at the time of its publication, but other technologies have recently emerged. One of these memory related technology is magnetoresistive RAM, or magnetic RAM which uses the term MRAM. Webopedia defines MRAM and links to other, older types of RAM such as DRAM. Wired has an article written in 2000 about the emergence of instant access memory. Read these two sites and then comment in this blog on the rapid changes in computer technology.
