Puzzled by PQ? Thrown by 3G? Nonplussed by nVidia?

Here's hoping our handy Glossary can set you straight, like a bridge over troubled water.

Ubuntu operating system


Ubuntu is a computer operating system based on the Debian GNU/Linux distribution, and is distributed as free and open source software, with frequent, regular releases and a consistent desktop interface. It is named after the Southern African philosophy of Ubuntu ("humanity towards others").  Ubuntu is backed by Canonical's commercial services and support on both the desktop and the server. It releases critical bug fixes and is never more than six months away from the latest version of anything in the open-source world. See also Kubuntu.


• Notion Ink initially announced the capability of running Android, Chrome OS and Ubuntu on ADAM; but as of December 2010, there is only an Android version available, with the custom Eden user interface built on top.

USB Flash Drive

A Universal Serial Bus flash drive consists of a flash memory data storage device integrated with a USB interface. USB flash drives are typically removable and rewritable, and most weigh less than 30 g (1 oz). Storage capacities in 2010 can be as large as 256 GB with steady improvements in size and price per capacity expected. Some allow 1 million write or erase cycles and have a 10-year data retention cycle. UFDs are often used for the same purposes as floppy disks or CD-ROMs were. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because of their lack of moving parts.

• ADAM has two type A USB ports into which UFDs may be plugged.

User Interface

The User Interface is the space where the interaction between a human and a machine occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the machine which aids the user in making operational decisions.


ADAM sports a user interface called Eden, which sits on top of the underlying Android operating system (diagram, left – click to enlarge).

Universal Serial Bus


USB can connect computer peripherals such as mice, keyboards, digital cameras, printers, personal media players, flash drives, Network Adapters, and external hard drives. For many of those devices, USB has become the standard connection method. Unlike older connection standards such as RS-232 or Parallel port, USB connectors also supply electric power, so many devices connected by USB do not need a power source of their own.


• ADAM has two type A USB ports and one mini A-USB port.

User eXperience

User eXperience (UX) is about how a person feels about using a system. User experience highlights the experiential, affective, meaningful and valuable aspects of human-computer interaction and product ownership, but it also includes a person’s perceptions of the practical aspects such as utility, ease of use and efficiency of the system.

ADAM's UX is mediated by its Eden user interface.
