What are the benefits of refresh and what is the use of refresh What does refresh do

Many people have the habit of clicking "refresh" on the context menu of the Windows desktop.

First, let's talk about the original meaning of "refresh". The explanation in the Windows XP help documentation is "Refresh the display information with the current data update". This feature is useful for many Windows applications, such as updating the display of file information in the browser, reloading pages in the browser, and so on.

The desktop is a special folder, the essence of which is refreshed is still to update the display information.

To illustrate the proper use of "refresh": you are browsing a folder with an explorer (including staring at a particular folder on your desktop without opening anything), and if some background program (e.g. FTP upload) generates some new files in that folder, but does not notify the explorer through the message loop, you need to manually refresh to see the new files. For example, if you're flashgetting a file, open the folder it's in, use the details view, and try refreshing it multiple times, you'll see that the file keeps growing in size.

While updating the display information, Explorer will also rearrange the icons in the way the user presets to keep the view neat and organized.

Refresh" also has some "side hustles". Since it informs the explorer of certain initialization operations, it is possible to make some changes to the registry key settings related to the explorer take effect immediately; Sometimes the explorer is abnormal, and it may be restored by refreshing it on the desktop; Sometimes there is a problem with the graphics card or application that causes a "color patch" to appear on the desktop, which can also be removed by a refresh.

However, the idea that "refresh is refreshing the system, clearing up memory space, and speeding up system response" is misleading for beginners. I really don't know who invented this theory and then spread it widely. A reasonable understanding is:

"Refresh" is a user self-comfort feature designed by Microsoft - the new one is better than the old one, and the refresh must be faster, maybe it will really feel faster after the refresh, so ...... be crazy

Summary. 1.Refresh:

That is, update the existing page.

Refresh while surfing the web will update the web page.

Refreshing the desktop will restore the desktop icon to a neat state, that is, update the desktop.

2.Why refresh:

Speed up system response.

Paste similar charts or files anywhere (no automatic sorting is selected), after pasting, you can see that there is overlap or messiness, refresh it, and you can see that the charts and files have become orderly (familiar with it: make the desktop cleaner)!

If you change the settings of some registry entries, you can refresh them on your desktop and take effect.

If the icons on the desktop are cluttered and you have a setting to arrange the icons, refresh it to rearrange it.

Pressing F5 without stopping can basically see the reaction speed of the machine. Refresh:

Summary. Refresh Reason - The attenuation of DRAM information stored due to capacitor leakage needs to be replenished in time, so regular refresh operations are arranged;

There are three commonly used refresh methods – centralized, decentralized, and asynchronous.

Centralized: During the maximum refresh interval, a period of time is arranged for refresh.

Decentralized: insert a refresh cycle after each read and write cycle, no CPU access dead time;

Asynchronous: It is a compromise between centralized and decentralized.

Hello, I have seen your question and am sorting out the answer, please wait for a while Refresh reason - the attenuation of DRAM information stored due to capacitor leakage needs to be replenished in time, so a regular refresh operation is arranged; There are three commonly used refresh methods – centralized, decentralized, and asynchronous. Centralized: During the maximum refresh interval, a period of time is arranged for refresh. Decentralized:

A refresh cycle is inserted after each read/write cycle, and there is no CPU access to the dead time; Asynchronous: It is a compromise between centralized and decentralized.

1. Refresh means that when the new settings cannot take effect automatically, the refresh makes the new settings take effect, and the current available resources of the system can be re-detected.

2. For example, if we change the icon for a shortcut on the desktop, the new icon will automatically take effect when we click "OK" or "Apply". But if, for some reason, the new icon doesn't show up, you'll need to manually refresh it for the new settings to take effect. In fact, in most cases, Windows itself can automatically refresh and make the new settings take effect, in most cases without the need for manual user intervention.

Just try refreshing it manually when you run into a problem. I often see many people refresh seven or eight times in a row, lest the system will not work if the number of refreshes is less, but in fact, there is no need at all.

3. In addition, refreshing the desktop has another function, which is to roughly detect the current available resource occupation of the system. For example, if a daemon is taking up a lot of system resources and busy, the refresh operation will be slow. If you have a lot of available system resources, the refresh will be very fast. Therefore, we can use the simple operation of refresh to roughly check whether the current key date content of the system is in a busy state.

The Windows desktop is sometimes stuck, such as the mouse's draft laughter movement track is retained, etc., in order to look good, so the desktop reset function was born, which is commonly known as refresh.
