              The 8mm backup format is a format for storing magnetic tape data used in computer systems, launched by Exabyte Corporation. It is also known as Data8, often abbreviated to D8 and writes D-Eight on some Sony brand media. The company was formed in order to take the 8 mm video format and make it suitable for data storage. They did this by building a mechanism and a reliable data format that used the common 8 mm video tape technology that was available at the time. This was the first form of helical scanning used commercially for data storage. The ribbon was made vertically and has a length of 112 meters. It was designed to withstand heat and high temperatures. It has been introduced in at CERN in 1994.

              Now called RSA SecurID, SecurID is a mechanism developed by Security Dynamics that allows two-factor authentication for a user on a network resource. It works on the principle of the unique password mode, based on a shared secret. Every sixty seconds, the component generates a new six-digit token on the screen. The latter comes from the current time (internal clock) and the seed (SecurID private key that is available on the component, and is also from the SecurID server). During an authentication request, the SecurID server will check the entered token by performing exactly the same calculation as that performed by your component. The server knows the two information required for this calculation: the current time and the seed of your component. Access is allowed if the token calculated by the server matches the token you specified.

              A new generation with a reworked motherboard is launched on 2001 with however the same Graphite box. It also included a processor speed-bump, and brought the DVD-R "SuperDrive" to the mid-level model. The Quicksilver PowerMac was available in three configurations: The 733 MHz model, with 128 MB of RAM, a 40 GB hard drive, and a CD-RW drive, was 1,699 dollars, the 867 MHz configuration, with 128 MB of RAM, a 60 GB hard drive and a DVD-R drive, was 2,499 dollars, and the high-end dual-800 MHz model, with 256 MB of RAM, an 80 GB hard drive and a DVD-R drive, was 3,499 dollars. The 733 MHz model is the first personal computer to have a DVD burner, named SuperDrive at Apple. The design was updated on 2002 with 800 MHz, 933 MHz and dual 1 GHz configurations, becoming the first Mac to reach 1 GHz.
