All Macs are now running OS 8.1 and Microsoft Office 98. These changes complement the PCs, which use Windows NT 4.0 and Microsoft Office 97. We continue to add new protections against computer viruses monthly. This process effectively replaces the software on PCs and Macs at regular intervals, greatly increasing the reliability and functionality of all lab machines and ensuring the uniform distribution of software upgrades and new software. Because of this, it is more important than ever to save your work on network drives, floppys, or Zip disks.
Work saved on local hard drives is erased each time a fresh image is loaded.
