In computing, BIOS is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process. The BIOS firmware comes pre-installed on an IBM PC or IBM PC compatible's system board and exists in some UEFI-based systems to maintain compatibility with operating systems that do not support UEFI native operation. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS originally proprietary to the IBM PC has been reverse engineered by some companies looking to create compatible systems. The interface of that original system serves as a de facto standard.
KNOPPIX is an operating system based on Debian designed to be run directly from a CD / DVD or a USB flash drive, one of the first live operating system distributions. Knoppix was developed by, and named after, Linux consultant Klaus Knopper. When starting a program, it is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly.
Mac OS 9 is the ninth and final major release of Apple's classic Mac OS operating system which was succeeded by Mac OS X in 2001. Introduced on October 23, 1999, it was promoted by Apple as "The Best Internet Operating System Ever", highlighting Sherlock 2's Internet search capabilities, integration with Apple's free online services known as iTools and improved Open Transport networking. While Mac OS 9 lacks protected memory and full pre-emptive multitasking, lasting improvements include the introduction of an automated Software Update engine and support for multiple users.
A USB flash drive is a data storage device that includes flash memory with an integrated USB interface. It is typically removable, rewritable and much smaller than an optical disc. Most weigh less than 30 g (1 oz). Since first appearing on the market in late 2000, as with virtually all other computer memory devices, storage capacities have risen while prices have dropped. As of March 2016, flash drives with anywhere from 8 to 256 gigabytes (GB) were frequently sold, while 512 GB and 1 terabyte (TB) units were less frequent. As of 2018, 2 TB flash drives were the largest available in terms of storage capacity. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to physically last between 10 and 100 years under normal circumstances.
Norton AntiVirus is an anti-virus or anti-malware software product founded by Peter Norton, developed and distributed by Symantec since 1990 as part of its Norton family of computer security products.

U3 was a joint venture between SanDisk and M-Systems, producing a proprietary method of launching Windows software from special USB flash drives. Flash drives adhering to the U3 specification are termed "U3 smart drives". U3 smart drives come preinstalled with the U3 Launchpad. Applications that comply with U3 specifications are allowed to write files or registry information to the host computer, but they must remove this information when the flash drive is ejected. Customizations and settings are instead stored with the application on the flash drive.
MediaPortal is an open-source media player and digital video recorder software project, often considered an alternative to Windows Media Center. It provides a 10-foot user interface for performing typical PVR/TiVo functionality, including playing, pausing, and recording live TV; playing DVDs, videos, and music; viewing pictures; and other functions. Plugins allow it to perform additional tasks, such as watching online video, listening to music from online services such as Last.fm, and launching other applications such as games. It interfaces with the hardware commonly found in HTPCs, such as TV tuners, infrared receivers, and LCD displays.
Windows Genuine Advantage (WGA) is an anti-infringement system created by Microsoft that enforces online validation of the licensing of several Microsoft Windows operating systems when accessing several services, such as Windows Update, and downloading Windows components from the Microsoft Download Center. WGA consists of two components: an installable component called WGA Notifications that hooks into Winlogon and validates the Windows license upon each logon and an ActiveX control that checks the validity of the Windows license when downloading certain updates from the Microsoft Download Center or Windows Update. WGA Notifications covers Windows XP and later, with the exception of Windows Server 2003 and Windows XP Professional x64 Edition. The ActiveX control checks Windows 2000 Professional licenses as well.
Cactus Data Shield (CDS) is a form of CD/DVD copy protection for audio compact discs developed by Israeli company Midbar Technologies. It has been used extensively by EMI, BMG and their subsidiaries. CDS relies on two components: Erroneous Disc Navigation and Data Corruption.
The terms Recovery disc, Rescue Disk/Disc and Emergency Disk all refer to a capability to boot from an external device, possibly a thumb drive, that includes a self-running operating system: the ability to be a boot disk/Disc that runs independent of an internal hard drive that may be failing, or for some other reason is not the operating system to be run.
Windows Live Mesh is a discontinued free-to-use Internet-based file synchronization application by Microsoft designed to allow files and folders between two or more computers to be in sync with each other on Windows and Mac OS X computers or the Web via SkyDrive. Windows Live Mesh also enabled remote desktop access via the Internet.
Oracle VM VirtualBox is a type-2 hypervisor for x86 virtualization developed by Oracle Corporation. VirtualBox was originally created by InnoTek Systemberatung GmbH, which was acquired by Sun Microsystems in 2008, which was in turn acquired by Oracle in 2010.
Norton 360, developed by Gen Digital Inc., is an “all-in-one” security suite for the consumer market. Originally released in 2007, it was discontinued in 2014; its features were carried over to its successor, Norton Security.
The security of Advanced Access Content System (AACS) has been a subject of discussion amongst security researchers, high definition video enthusiasts, and consumers at large since its inception. A successor to Content Scramble System (CSS), the digital rights management mechanism used by commercial DVDs, AACS was intended to improve upon the design of CSS by addressing flaws which had led to the total circumvention of CSS in 1999. The AACS system relies on a subset difference tree combined with a certificate revocation mechanism to ensure the security of high definition video content in the event of a compromise.
The PlayStation Portable system software is the official firmware for the PlayStation Portable (PSP). It uses the XrossMediaBar (XMB) as its user interface, similar to the PlayStation 3 console. Updates add new functionality as well as security patches to prevent unsigned code from being executed on the system. Updates can be obtained in four ways:

An Android version was released in 2014.
gOS or "good OS" was an Ubuntu-based Linux distribution created by Good OS LLC, a Los Angeles-based corporation. Its CIO David Liu described that after meeting Enlightenment and open source people, he realized that his dream to bring Web 2.0 applications into mainstream use could be achieved by creating a Linux distribution that made it easy for users to access Google and Web 2.0 applications. David Liu went on to create the Chinese Twitter clone called Wozai (我在), leaving gOS officially defunct.
Carbonite, Inc. is an American company that offers an online backup service, available to Windows and macOS users. In 2019 it was acquired by Canadian software company OpenText. It backs up documents, e-mails, music, photos, and settings. It is named after carbonite, the fictional substance used to freeze Han Solo in Star Wars: The Empire Strikes Back. Carbonite was the first such service to offer unlimited backup space for a fixed price. Previously, all online backup services were priced by the gigabyte; many other vendors have since changed to an unlimited model.
μTorrent, or uTorrent is a proprietary adware BitTorrent client owned and developed by Rainberry, Inc. The "μ" in its name comes from the SI prefix "micro-", referring to the program's small memory footprint: the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet. μTorrent became controversial in 2015 when many users unknowingly accepted a default option during installation which also installed a cryptocurrency miner.
