Travel weight
The total weight of a
notebook computer package that includes the notebook, transformer,
carrying case, external drives, cables, full-size battery pack and
adapters for connecting accessories — all devices that are necessary
to keep a mobile computing environment functional. Travel weight is a
concern for notebook users who rely on the mobility of their notebook
devices. A notebook’s travel weight is different than its system
weight, which refers to the weight of just the notebook device and not
any of the accessories. Unless the term travel weight is used, one
should assume that any quoted weight only refers to the system weight.
Sandbox
A security measure in the
Java development environment. The sandbox is a set of rules that are
used when creating an applet that prevents certain functions when the
applet is sent as part of a Web page. When a browser requests a Web page
with applets, the applets are sent automatically and can be executed as
soon as the page arrives in the browser. If the applet is allowed
unlimited access to memory and operating system resources, it can do
harm in the hands of someone with malicious intent. The sandbox creates
an environment in which there are strict limitations on what system
resources the applet can request or access. Sandboxes are used when
executable code comes from unknown or untrusted sources and allow the
user to run untrusted code safely.
