What does refresh do, what does refresh do

Right-click on an empty space on the desktop, there is a "Refresh" option, what is the use?

Generally useless.

However, if you have closed some windows and there are still residual images left on the desktop, or you feel that the screen is not displayed correctly, you can click "Refresh" and it will generally return to normal.

Also, sometimes you change the icon of a desktop shortcut, but the display does not change, and clicking "Refresh" can also show the new icon.

Therefore, the refresh function is to clear the displayed cache and display the latest desktop. This is also the meaning of "refresh" in other windows or software.

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.

I've seen jokes about keyboard wear and tear on the Internet before, and the F5 key is mentioned. If someone's F5 key is worn badly, they must like to refresh, and this kind of person will keep brushing the newspaper with a leather puff when he goes to the toilet to read the newspaper, hoping to see the updated content.

Refresh in the browser is to update the current web page, that is to say, re** this page, desktop refresh is to clear the displayed cache, display the latest desktop. This is also the meaning of "refresh" in other windows or software.

It is to re-display the window that cannot be displayed normally.,By the way,Sometimes the general refresh doesn't work--- that is f5 doesn't work.,You can use ctrl+f5 to force the refresh.。 Thank you.

Recover the error of the last operation or open the latest page!

Whatever you use, I think.

It's purely a personal habit.

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.

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.

What is a refresh? Why refresh? DescriptionThere are several ways to refresh.

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.
