The Mac II had eight 30-pin SIMMs, and memory was installed in groups of four (called "Bank A" and "Bank B"). The original Macintosh II did not have a PMMU by default. It relied on the memory controller hardware to map the installed memory into a contiguous address space. This hardware had the restriction that the address space dedicated to ...

Mac OS X revived the use of AppleDouble; on file systems such as NFS and WebDAV that do not natively support resource forks, Finder information, or extended attributes, that information is stored in AppleDouble format, with the second file having a name generated by prepending "._" to the name of the first file (thus, this information acts as a ...
