A touchpad or trackpad is a type of pointing device.Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a pointer in a graphical user interface on a computer screen.
The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized. According to Microsoft's MSDN website, the default timing in Windows is 500 ms (half a second). [6] The double-click time is also used as a basis for other timed actions.

Internal view of a Macintosh LC. The LC uses a "pizza box" case with a Processor Direct Slot (PDS) but no NuBus slots.

The LC has a 16-bit data bus, which is a major performance bottleneck as the 68020 is a 32-bit CPU.
Instead of placing windows all over the screen, the windowing manager, Con10uum, uses a linear paradigm, with multi-touch used to navigate between and arrange the windows. [62] An area at the right side of the touch screen brings up a global context menu, and a similar strip at the left side brings up application-specific menus.
TAP, namely network TAP, simulates a link layer device and operates in layer 2 carrying Ethernet frames. TUN is used with routing. TAP can be used to create a user space network bridge. [2] Packets sent by an operating system via a TUN/TAP device are delivered to a user space program which attaches itself to the device. A user space program may ...
