activity terms

taking a pic

annotating a page
animating a drawing
making sounds & music
measuring and sensing
sharing your favorites
inviting your friends
surfing on the web, etc...

XO terms

school server
a machine at each school that works as an access point and provides
serverless peer-to-peer
a wayof providing peer-to-peer sharing of data via peer-to-peer connectivity, from one XO to another.
XS server
see school server

networking terms

infrastructure
sometimes used to describe traditional network connectivity, with an access point
mesh
see mesh layer
mesh view (AKA neighborhood view)
A view of who is sharing the mesh network with you. See sugar terms
mesh layer
a layer that can run over peer-to-peer, over infrastructure, etc.
peer-to-peer
see serverless peer-to-peer
presence
jabber
networking protocol that the XO uses
tubes
tubes runs over the mesh and over traditional infrastructure.
simple mesh
school server mesh
mesh channel
access point
infrastructure mode
mesh portal point

terms for the outer case

dual-tone
the two-color nature of the icon on the outside of the laptop; one color or tone for the o and the other for the x

Hardware and firmware terms

Forth
God's gift to terse programmers
Open Firmware
God's gift to hardware debuggers
System Firmware
The system firmware is made up of 2 parts: The EC and OFW. The first part is the software that runs the embedded controller (EC). The EC handles the processing of the keyboard, touchpad, game buttons, power button, and charging the battery. The second part is OpenFirmware (OFW). OFW is responsible for initializing the hardware and booting the operating system. OFW also handles boot security so that it will only load "offical" OLPC operating systems.
Wireless Firmware
The wireless firmware is software that controls the operation of the wireless radio. It is downloaded into the wireless radio by the operating system.

external storage device terms

Jumpdrive
A small, external storage device that plugs into one of the USB ports on a computer. They can store between 16MB (enough to hold several music files) up to 4GB (enough to hold several high quality full-length movie files) and a wide range in between. Jump drives are easily purchased at any electronic store starting as low as $5 to $10.
Thumb drive

USB drive

USB Stick

home view
a view of what activities you are running, and how much memory they take—the starting view on the laptop;
group view
a view of your friends with whom you are working on shared projects;
neighborhood view
a view of who is sharing the network with you (mesh or otherwise) and what activities are being shared there;

Security

BitFrost
the OLPC security platform.
Rainbow
Rainbow implements the isolation shell implicitly described in the Bitfrost security specification. This means that it isolates activities (and eventually system services) that it is asked to run from one another and the rest of the system.
Activation
In order to use your laptop for the first time (or after a "reflash" of the operating system), it must be unlocked by an activation key.
Activation key
The key that unlocks the laptop
Developer key
If the boot firmware sees a developer key, it makes the XO laptop work just like any ordinary PC-style laptop, in the sense that it will let you interrupt the boot process and enter commands; and it will try to boot and run any program you supply to it, no matter whether the OLPC organization has tested or signed it. (The laptop also works this way if its firmware security is disabled.)
Signed/unsigned builds
OLPC produces both "signed" and "unsigned" builds of the operating system. Signed builds are release builds that have undergone QA testing. Unsigned builds are development builds, which are used for testing new features and bug fixes. You cannot run an unsigned build in your laptop unless you have either a developer key or security has been turned off (as in the case of the G1G1 laptops).
key generation
The process of generating both activation and developer keys
lease
When a laptop is activated, the activation has an expiration date. The period between activation and expiration is the lease period. The lease period is determined during the key-generation process; the laptop can be reactivated after the lease has expired.
passive kill
currently unsupported, this is a mechanism that uses the lease mechanism to require laptops to periodically ask for a renewed activation. Without the renewal, the lease will expire and the laptop will be locked.
active kill
currently unsupported, this is mechanism where by a laptop that has been reported stolen can be remotely shutdown when it connects to the Internet.
virus
malware
