Comptia A+ 220-802 Chapter 12 Flashcards
A program that runs on top of the OS and allows the user to issue commands through a set of menus or other interface (which may or may not be graphical). Shells
make an OS easier to use by changing the user interface. pg 565
Shell
A method by which a person communicates with a computer using graphical images, icons, and methods other than text. pg 565
Graphical user interface (GUI)
Any group of computers that have a communication link between them. pg 565
Network
A multitasking method that depends on the application itself to be responsible for using the processor and then freeing it for access by other applications. pg 565
Cooperative multitasking
A multitasking method in which the OS allots each application a certain amount of processor time and then forcibly takes back control and gives another
application or task access to the processor. pg 565
Preemptive multitasking
The ability of a single application to have multiple requests in to the processor at one time. This results in faster application performance because it allows a
program to do many things at once. pg 565

When it comes to interacting with a mouse in Windows, there are three possibilities: pg 573
**Primary mouse click—A single click (typically the left mouse button) used to select an object or place a cursor.
**Double-click—Two primary mouse clicks in quick succession. Used to open a program through an icon or for other application-specific functions.
**Secondary mouse click (or alternate click)—Most mice have two buttons. Clicking once on the secondary button (usually the one on the right, although that can
be modified) is interpreted differently from a left mouse click. Generally, in Windows this click displays a context-sensitive menu from which you can perform
tasks or view object properties.

This option places the computer into a hibernation
state. The session is saved and can be restored, but monitor and hard disks are turned off. pg 581
Sleep (Windows 7 and Windows Vista only)
This option places the computer into a low-power state.
The monitor and hard disks are turned off, and the computer uses less power. pg 581
Stand By (Windows XP only)
What are icons? pg 581
Icons are shortcuts that allow a user to open a program or a utility without knowing where that program is located or how it needs to be configured.
When you delete files where does the computer send them too? pg 584
The Recycle Bin
Used to change the state of the window on the
Desktop. pg 585
Minimize and Maximize/Restore buttons
Used to easily end a program and return any resources it was using to the system. It essentially does the same thing as double-clicking the control box, but with one
less click. pg 586
Close button
The area between the control box and the Minimize button. It states the name of the program and in some cases gives information about the particular document being accessed by that program. pg 586
Title bar
Used to present useful commands within an application in an easily accessible format. Clicking one of the menu choices displays a list of related options you may choose from. pg 586
Menu bar
The window that is currently being used. pg 586

is a copy of your system configuration at a given point in time.
restore point
How are the 3 ways.Restore points are created? 591
- Windows creates them automatically by default.
- Two, you can manually create them yourself (which is highly recommended before you make
any significant changes to the system, such as installing new drivers). - Three, during the installation of some programs, a restore point is created before the installation; that way, if
the install fails, you can “roll back” the system to a preinstallation configuration.
In Win7 what is the path to set up a restore point? pg 591
Start > All Programs > Accessories > System
Tools > System Restore.
what is a path? pg 593
A path indicates the location of the file on the disk; it is
composed of the letter of the logical drive the file is on and, if the file is located in a directory or sub directory, the names of those directories.
