instantiation: Creates an instance of a class, the concrete object of the class.
method: a function defined in a class.
object: An instance of a data structure defined by a class. The object consists of two data members (class variables and instance variables) and methods.

it's not easy to really implement it. "Add a touch screen" is very simple, but this is missing the fundamental sense of the return to the simple spirit of innovative interactive design of the spiritual core.

In-depth understanding of the Linux kernel, there are three chapters on memory management, this is a chapter, and the eighth chapter discusses how the kernel assigns itself main memory, and the Nineth chapter, considering how to assign a linear address to a process.
Memory Address--(P40)
The following three types of addresses are relative to the 8086 processor.
Logical addresses (logical address)

an object. The acceleration of motion is also changed, and if the acceleration is taken, what force the object is subjected to or what kind of motion the object carries out, we can know. Using acceleration, we can do the simulation of pedometer, object motion application. the 3 elements of the values variable of the accelerometer are represented by X,Y , respectively. , Z the acceleration value of the axis. the gravity sensor uses the same set of coordinate systems as the accelerometer sensor
