what is the printscreen key on a laptop
Print screen In Microsoft Windows, pressing Prt Sc will capture the entire screen,[1] while pressing the Alt key in combination with Prt Sc will capture the currently selected window.[1] The captured image can then be pasted into an editing program such as a graphics program or even a word processor. Pressing Prt Sc with both the left Alt key and left ⇧ Shift pressed turns on a high contrast mode (this keyboard shortcut can be turned off by the user).[2] Since Windows 8, pressing the ⊞ Win key in combination with Prt Sc(and optionally in addition to the Alt key) will save the captured image to disk (the default pictures location).[3] This behavior is therefore backward compatible with users who learned Print Screen actions under operating systems such as MS-DOS.

Taskbar The specific design and layout of the taskbar varies between individual operating systems, but generally assumes the form of a long strip along one edge of the screen. On this strip are various icons which correspond to the windows open within a program. Clicking these icons allow the user to easily switch between programs or windows, with the currently active program or window usually appearing differently from the rest. In more recent versions of operating systems, users can also "pin" programs or files so that they can be accessed quickly, often with a single click. Due to its prominence on the screen, the taskbar usually also has a notification area, which uses interactive icons to display real-time information about the state of the computer system and some of the programs active on it.
1st & Ten (graphics system) The system makes use of a combination of motion sensors mounted on the broadcast cameras to record what they are viewing,[4] and/or the use of match moving computer graphics technology[5] and an enhanced version of chroma key or "green screen" technology.[6]
Cerebrum With the assistance of the cerebellum, the cerebrum controls all voluntary actions in the body.
Malware Once a malicious program is installed on a system, it is essential that it stays concealed, to avoid detection. Software packages known as rootkits allow this concealment, by modifying the host's operating system so that the malware is hidden from the user. Rootkits can prevent a malicious process from being visible in the system's list of processes, or keep its files from being read.[25]
