Automatic computer shutdown tutorial

Windows XP have a shutdown of the process, it is the Windows \ System32 under Shutdown.exe. If your computer shuts down at 22:00, select "Start → Run", enter time "at 22:00 Shutdown-s", this time the computer 1-22 immediately a "System Shutdown" dialog box, the system will countdown at 30 seconds after you save job tips. You can select the way the countdown shutdown, method: Enter the "Shutdown.exe-s-t 3600", 3600 that 3600 seconds is a small one.
Set up after the good, but suddenly you do not want to automatically shutdown, method: enter "shutdown-a". Also enter "shutdown-i", will open the automatic shutdown dialog box, you can set up automatic shutdown.
Shutdown.exe parameters, each with a specific purpose, the implementation of each will have different effects, such as "-s" on that turn off the local computer, "-a", said the abolition of shutdown operation, following is a list of more parameters, we can use at Shutdown.exe in on-demand.
-F: force close the application -M \ \ computer name: control of remote computer
-i: show the graphical user interface, but must be the first option Shutdown

Keyboard Development

Brief Introduction keyboard: Computer development in recent years more and more quickly, with the development of computer hardware, there is a lot of hardware are eliminated. However, some computer components have always maintained, we know that the keyboard is one of them. Although the sweep scanning device, WordPad emerging, but the keyboard is still exist.
Previous keyboard has 84 keys, with the hardware technologies improve a 101 key keyboard, mainly add some new function keys. Later Windows system, change to 104 key keyboard, which is now the mainstream of the keyboard with 101 keys compared to the previous add the Win key and a menu key, to enable easy manipulation of the system.
General keyboard layout is similar to the basic, fundamental divided into four categories:
A. function keys: F1 ~ F12, at the top of the keyboard, and function depends on the software programs, different software and its function may differ, if Word is used in the search to replace F5, F5 in IE while Medium is used to refresh.
B. Main keyboard: it is our normal place for typing, it accounts for the largest piece of the keyboard are, there is A ~ Z a total of 26 letters, number keys, symbol keys and the spacebar, Enter and so on.
C. small keyboard: is the number keys and the addition and subtraction multiplication and division operator key places, at the right side of the keyboard, this side is designed for statistical data.
D. other keys: the main keyboard and numeric keypad between the four arrow keys and the Home, End keys, etc..
Now a lot of the keyboard is designed according to ergonomic, multi-functional Internet keyboard, remote control keyboard, a variety of tablet keyboard, function keys so that we become more and more convenient operation.
Apart from the special function keys, the basic 104 key keyboard with almost. Future Development: With the development of science and technology, the keyboard function will be more and more strong, and for our lives more convenient. Benefit such as near the last few years there have been touch-screen technology, which monitors keyboard and mouse with integrated, direct hand pointing to the control computer screen.

1G Free space

This is 1G of free space address:http://www.5944.net/
this free space to support
html asp php
Also supports the bonding domain name It is a pity is that there is no sql data.

If you used to study, this space still can, but if you make a stand, it is intended for future development, you are better to buy a space. Since I have used this space to a certain time will be the problem.

Installed anti-virus software has become very slow computer

Ago, had thought that the antivirus software can be installed to prevent the virus from entering your computer, so each system must be re-install a antivirus software, but with the escalation of anti-virus software, accounting for more and more resources, and install antivirus software, computer will become very slow very slow. This is normal!

How can we make it, first bought a better computer Units, two anti-virus software is not installed. In fact, if you computer does not have any important documents, are not installed antivirus software. Since installed antivirus software is not 100 percent to prevent the virus, another virus will always have a little more than anti-virus software updates faster, in other words the only antivirus software with virus.

So if there is no particular importance to the things we can install a 360, there was little need to install antivirus software.

Delete files at ease

At uninstall applications, you will be prompted "The system indicates that the following shared file is no longer used by any programs" (If the following shared file is deleted, will not be able to re-use of any other procedure), in the end should not delete the these documents? It is very difficult to answer this question in one sentence, but the fortunate thing is that this problem would not normally bring disastrous consequences.

Windows system will be preserved in the registry of a counter used to record each file-sharing the number of applications. When you install the application necessary to use a certain file, the registry of the document corresponding counter will add one. And when you uninstall an application, the corresponding counter will be minus one. When the document into a 0:00 counter, you will receive the above information, because the system think you delete the last file to use this procedure. But the system is not always correct, install and uninstall software, the process is not always smooth and unmistakable, there is so counter may be wrong.

How to solve it? If you worry about running low on disk space, you can click "Yes To All" button to delete all the shared files, it appears unlikely the problem. Even if true there is problem, you can still use this to reinstall file-sharing applications. If there is enough disk space, you can temporarily remove these shared files. These documents apart from taking up some disk space, has no effect on the system.

Computer slowing down after the Games finish off

Sometimes after the Games finish off a number of large-scale or large-scale software run finished, it was found that a very slow computer. This is why. In fact, depositors are due to failure to make timely release into the Game or the memory of large-scale software. So that very slow computer
Solution: start - write-off. Is that simple, put all of a sudden release of memory

Pixels with the resolution, what is the difference?

1. What is a pixel? Put simply, we are usually talking about pixels, is the CCD / CMOS optoelectronic sensors on the number of components, a photosensitive element after photographic, photoelectric signal conversion, A / D conversion step, the output at the photo on the formation of a point, if we put the image to enlarge several times, you will find that these are in fact continuous tone color similar to those of many small parties consisting of points, which constitute a small side point is the smallest unit of image "pixels" (Pixel). CCD pixels are divided into pixels and effective pixels, is now on the market marked the majority of digital cameras are CCD pixels rather than an effective pixel.

2. What is the resolution? Speaking of pixels on the resolution had to talk about. Since the two are inseparable! The so-called "resolution" refers to units of length, the expression or the number of captured pixels. And pixel, the resolution also divided into many versions. One of the most common is the image resolution, we usually say that the output of digital camera photos maximum resolution, refers to the image resolution, units are ppi (Pixel per Inch) Print resolution is also very common, as the name implies, is the printer or printing equipment, the output resolution, unit is the dpi (dot per inch) Display resolution, is the Windows desktop size. Common settings have 640x480, 800x600, 1024x768 ... and so on. Screen font resolution: PC font resolution is 96dpi, Mac font resolution of 72dpi. Of course there will be other output device resolution. Because of a wide range, in this not described in detail, there is interest in a friend can go online search.

3. Pixel image resolution and the relationship between the That said, the definition of pixels and resolution, let us take a look at the relationship between the two. Friend may be careful has been found that pixel and resolution are directly proportional to, the greater the pixel resolution is also higher. Let us take an example! Previously mentioned, sub-pixel effective pixels and the CCD pixel Normally two million-pixel digital camera, the largest-resolution images are 1600 × 1200 = 192 million pixels, in other words, the actual effective pixels is 1,920,000. Commonly referred to as three million pixel digital camera, the largest-resolution images are 2048 × 1536 = 3145728 pixels, that is to say 3,140,000 effective pixels. Other-pixel digital camera, its effective pixel resolution and conversion is also true. Can be seen that the higher the pixels, maximum output is also higher resolution images.

4. Printing resolution and the relationship between pixel Print resolution, related to the size of our photo prints, and therefore more important. In fact, method of calculation is very simple: 2,000,000-pixel digital camera, 1.92 million effective pixels, maximum output of 1600 × 1200 Photos Wide: 1600 Pixels/300 dpi = 5.3 " High: 1200 Pixels/300 dpi = 4 " This means that if the output resolution of 300dpi prints, prints up to 5.3 × 4-inch photos, but usually the size of photos are: 5 inch: 5 × 3.5 6 inch: 6 × 4 It is clear that the two million pixels to 300dpi the effect of processing the largest 5-inch photos. (Note: The human eye can tell the maximum resolution is 300dpi, beyond this resolution, people's eyes are unable to see the difference, that is to say 300dpi and 600dpi people at a glance there is no difference, so now processing equipment The biggest design output resolution is 300dpi, of course, each person's request for clarity is not the same as, in general can achieve 200dpi will be able to let the majority of people satisfied with the two million so-pixel prints 6-inch photos, in most people it seems very clear.)

Summary: As mentioned above, the "print size" and the image resolution are closely related, as long as the image resolution has changed, the size of print will be followed by changes in pixel resolution and image have a direct relationship, so the three can be mutual conversion. And one of the most fundamental is the pixel.

So buy a digital camera, the pixel is also an important consideration, the specific needs of the number of pixels, can be according to their own needs.

Paternity machine can be shutdown

There is a lot of time, we have some things I want to go out of one, so we set up paternity machine.

In fact, paternity machine is this: apart from computer motherboards from other parts of memory are off, meaning that only the memory work. And we usually normal shutdown, are in order to protect the hard drive.

Because of the hard disk inside the disk with a very small distance between the head and suddenly the pass off very easily hurt the hard drive. And paternity machine, the hard disk itself has been shut down. Do not worry, therefore, we can disconnect the power directly.
