statements cause task switching, the CPU automatically saves the TSS content of the current task, and restores the TSS content of the task that needs to be switched to, causing the task to switch. The description of Task 1 and Task 2 is similar to task 0.

In order to be in physical memory, the new process shares the same memory area as the original process when it calls fork () to generate a new process. Only when one
If you have used Windows 8, you must try Windows 8 with Windows 8's full screen win + prtSc.In other words, we have a shortcut screenshot key in Windows 8: win + prtSc. We all know that prtSc is a shortcut key in Windows.However, in Windows
initialization.Planet sphere = planet. Mars;
This makes it difficult for us to use this type in other types, because we don't know what value to initialize it.
Using this type to create an object will create an invalid planet.Observationdata d = new observationdata ();
Make sure that 0 is a valid value. If possible, it should be the best default value. There is no optimal solution for planet enumeration. When the user does not use it, it should not c

4) How to useThe same I put about the 3461AS package up (below)In the file where you want to use the feature, first include the header file, and then reference the Duanma array, the TempData array, and the display function for displaying.Then store the data in TempData before y
In Windows NT, The 80386 protection mode is more robust than Windows 95, and this "gold-plated cage" is more robust and hard to break. In Windows 95, at least application I/O operations are unrestricted, while in Windows NT, our applications are deprived of this permission. In NT, it is almost impossible to enter the real ring0 layer.In Windows NT, there are three device drivers:
1. "virtual device driver" (VDD ). Through VDD, 16-bit applications, such as DOS and Win16 applications, can access s

This chapter mainly describes what is [BX] and loop (loop) instruction how to use, loop and [BX] how to combine, what the paragraph prefix is what ghosts, and how to use the paragraph prefix. 1, [BX] concept [BX] and [0] similar, [0] indicates that the memory unit offset address is 0. To fully describe a memory unit, you need two kinds of information: the address

If defined #pragma pack(2) , thesizeof(S1)=8;sizeof(S2)=8

); Returns 2parseint ("10", 8); Returns 8parseint ("10", 10); Returns 10If the decimal number contains a leading 0, it is best to use cardinality 10 so that the octal value is not unexpectedly obtained. For example:parseint ("010"); Returns 8parseint ("010", 8); Returns 8parseint ("010", 10); Returns 10The Parsefloat () method is similar to the parseint () method
