3.Define Graphical User Interface:
“A graphical system consists of objects and actions. Objects are what people see on the screen. They are manipulated as a single unit. A well-designed system keeps users focused on the objects, not on how to carry out actions.”

4. What is Persistence:
The maintenance of a state once it is established. An object’s state hould always be automatically preserved when the user changes it.

5.Describe the Principles of Good Screen Design?
A well-designed screen: . Reflects the capabilities, needs, and tasks of its users . Is developed within the physical constraints imposed by the hardware on which it is displayed. . Effectively utilizes the capabilities of its controlling software . Achieves the business objectives of the system for which it is designed .

6. Give some Common Usability Problems? . Ambiguous menus and icons . Languages that permit only single-direction movement through a system . Input and direct manipulation limits . Highlighting and selection limitations . Unclear step sequences . More steps to manage the interface than to perform tasks .

7. What are the Elements of Good Screen Design?
. Upper-left starting point . Provide an obvious starting point in the screen’s upper-left corner . Screen navigation and flow . Visually pleasing composition . Balance . Symmetry . Regularity . Predictability

8. Define the components of Memory. 
There two components: Long term memory contains the knowledge we posses. Short termreceives information from either the senses or the long term memory.

9.What is Information Processing?
The information that our senses collect that is deemed important enough to do something about then has to be processed insome meaningful way.

10. What are the main Functions of Menus? 
. Navigation to a new menu . Execute an action or procedure . Displaying information . Data or parameter input .

A touch screen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the device with a finger or hand. Touch screens can also sense other passive objects,

5. What is Pull-down Menus & Drop-down Menus?
Pull-down menus are menus that the user can "pull down" from the menu bar that traverses the top of the screen. On some platforms these are called "drop down" menus because the user does not need to hold the mouse button down in order for the menu to remain visible.

6. Write note on Events ?
An "event," with respect to user interfaces, is any function initiated by the user. Selecting
something from a pull-down menu, clicking a button or a checkbox, and closing a window are all examples of events.
