Recently, I used the Windows system performance statistics program to collect statistics on CPU usage, memory usage, and network traffic. Now I want to sort it out (three articles in total) and hope to help you.
The directory is as follows:

When we say that a CPU is "32-bit" or "64-bit", it refers to the width of the arithmetic logical unit (ALU) in the CPU, this corresponds to the number of registers in the CPU. The larger the number of digits, the larger the data processed at a time. More information can be processed.
In computer systems, the data bus width is usually the same as that of ALU, but

1. Use debug to write the following program segments to the memory and execute them one by one. Observe the changes in the CPU registers after each command is executed.
?(1) Use the e command to modify the memory unit starting from and write the machine code
(2) run the U command to view the meaning of the machine code in the memory.
(3) The initial

Measures taken:
IIS service manager ---- application pool ---- add your application and set the maximum memory. When the Program reaches the maximum memory, it will automatically restart.
Upgrade the memory to 2 GB, And the access traffic is relatively high. Generally, it takes about 24 hours to restart. The memory is not used up, and the W3WP process accounts for one hundred and eight 90 MB, when SQL accounts for more than two hundred logs
I will upload my new book "Write CPU by myself" (not published yet). Today is 15th articles. I try to write them every Thursday.
In the previous chapter, the original five-level pipeline structure of openmips is established, but only one Ori instruction is implemented. It will be gradually improved from this chapter. This chapter first discusses issues related to pipeline data, then modifies openmips to solve the problem, and verifies the solution i

How is a CPU and computer heart made?
Silicon Wafer manufactured by Silicon Ingot Slicing
1. A large Silicon Single Crystal or ingot (purity 99.999999999%) is cut by a diamond blade to make a thin silicon wafer.
2. The surface of the silicon wafer is polished to make a mirror.
Processing surfaces to manufacture Semiconductors
3. oxide films are generated on the wafer surface.

Some students found that the CPU does not support virtualization when installing the virtual environment with the book CD, so I made a virtual environment that does not require virtualization, using virtual box, UBUNTU linux10.04 lts (around 4 GB)
You can download and use it if necessary. This virtual environment contains the lab environment required in the book (except for AndroidSource code, Too big, you need to write it yourself, otherwise it will

MySQL database versions are updated quickly, and new features are constantly updated. What's more, it solves many bugs that affect our applications. In order to make our MySQL better, we need to upgrade it, even though you will say it is running well and stable, and it is enough. Next, let's take a look at several common upgrade methods.
