As computers go these days, it is not unusual for the amount of free RAM to reach a critical level at which no other processes will fit into what little unused memory is left. Modern operating systems will then start swapping pages of memory to disk to make room; the data can be read back in later if necessary. This is a procedure called swapping, and it can take several forms. Windows maintains a large hidden file somewhere on the drive (usually in the root directory of C:) which it uses for this purpose. Linux, UNIX, and UNIX-alikes most often …
If you've been following the saga of Torrentspy, then you know that the Motion Picture Association of America has been trying to force the website's admins to start logging all of the activity on their site so that the MPAA can then subpoena the records and track down people who've been illegally downloading pirated movies.

And the hits just keep on coming.. researchers at UCLA have developed a memory circuit that can store 20KB of data in a physical space the size of a white blood cell. Compared to current random-access memory circuits of 2007, this new circuit has a data density of 100 gigabits per square centimeter, which is a new world record, if nothing else. That single memory cell can store the complete text of the Declaration of Independence of the United States of America and still have some room left over. Unfortunately, this is just a lab toy, and isn't anywhere near …
