8. The terminal of claim 2, wherein when the user touches the touch-screen display with a pointer at a first position and at a second position on the touch-screen display at the same time, and drags the pointer to a third position on the touch-screen display, the controller further determines a direction in which the user drags the pointer.

9. The terminal of claim 8, wherein when the user drags the pointer in a first direction, the controller determines the user is cutting the data between the first and second positions to the third position to be later pasted at another position on the touch-screen display, and when the user drags the pointer in a second direction different than the first direction, the controller determines the user is deleting the data between the first and second positions to the third position.

10. A terminal comprising:

a touch-screen display configured to be touched by a user; and

a controller configured to determine an area of the touch-screen display that is touched by the user and to perform an operation on data displayed on the touch-screen display based on the determined area of the touch-screen touched by the user.

11. The terminal of claim 10, wherein when the user touches a first position on the touch-screen display and drags a pointer to a second position on the touch-screen display, the controller deletes data displayed on the touch screen within an area between the first and second positions.

12. The terminal of claim 10, further comprising:

a selectable option configured to be selected by the user to indicate whether the operation performed on the data on the touch-screen display is a deletion operation or a cutting and pasting operation.

13. The terminal of claim 10, wherein when the user touches with a pointer a first position on the touch-screen display and drags the pointer to a second position on the touch-screen display, the controller further determines a direction in which the user drags the pointer.

14. The terminal of claim 13, wherein when the user drags the pointer in a first direction, the controller determines the user is cutting the data defined within an area between the first and second positions to be later pasted at another position on the touch-screen display, and when the user drags the pointer in a second direction different than the first direction, the controller determines the user is deleting the data defined within the area between the first and second positions.

15. A terminal comprising:

a touch-screen display configured to be touched by a user; and

a controller configured to determine that a user has touched a first position on the touch-screen display with a pointer and dragged the pointer to a second position on the touch-screen display, and to perform an operation of the data displayed on the touch-screen display from the first position to the second position.

16. The terminal of claim 15, further comprising:

a selectable option configured to be selected by the user to indicate whether the operation on the touch-screen display is a deletion operation or a cutting and pasting operation.

17. The terminal of claim 15, wherein when the user touches the touch-screen display with the pointer at the first position and drags the pointer to the second position on the touch-screen display, the controller further determines a direction in which the user drags the pointer.

18. The terminal of claim 17, wherein when the user drags the pointer in a first direction, the controller determines the user is cutting the data between the first and second positions to be later pasted at another position on the touch-screen display, and when the user drags the pointer in a second direction different than the first direction, the controller determines the user is deleting the data between the first and second positions.

19. A method for executing a function on a terminal, said method comprising:

determining a number of simultaneous touches on the touch-screen; and

performing a function based on the determined number of simultaneous touches.

20. The method of claim 19, wherein the number of simultaneous touches corresponds to a user simultaneously touching at least two different positions on the touch-screen at a same time.

21. The method of claim 20, wherein the function is a deletion command configured to delete data displayed on the touch-screen or is a paging command configured to flip through pages in an electronic book displayed on the touch-screen.

22. The method of claim 21, wherein when the user touches the touch-screen display with a pointer at a first position and at a second position on the touch-screen display at the same time, and drags the pointer to a third position on the touch-screen display, the deletion command deletes data displayed on the touch-screen display from the first and second positions to the third position on the touch-screen display.

23. The method of claim 21, wherein the performing step flips through a respective number of pages according to the number of simultaneous touches on the touch-screen.

24. The method of claim 19, further comprising:

selecting whether an operation on the touch-screen display is a deletion operation or a cutting and pasting operation,

wherein when the user touches the touch-screen display with a pointer at a first position and at a second position on the touch-screen display at the same time, and drags the pointer to a third position on the touch-screen display, the performing step determines a direction in which the user drags the pointer, and

wherein when the user drags the pointer in a first direction, the performing step determines the user is cutting the data between the first and second positions to the third position to be later pasted at another position on the touch-screen display, and when the user drags the pointer in a second direction different than the first direction, the performing step determines the user is deleting the data between the first and second positions to the third position.

25. A method for executing a function on a terminal, said method comprising:
