Why do we refresh our computer desktop???

Hello everybody, today I am going to tell you the reason behind refreshing a computer. This article is specially for my Windows user friends. In my teaching experience 100% students in the class admit that they do refresh a computer after start-up or during usage of computer. Interesting fact is that almost all of them don’t know reason behind refreshing.

Question is still the same. Why do we refresh our computer desktop? You can get an idea about it here.

1. Suppose you need to do 3 hard tasks in 1 hour.
2. You work hard and complete your first task.
3. Now before starting second task, you wipe sweat and drink water or to say you refresh your working state.
4. Similarly, refreshing a computer is to refresh state of an operation in computer and show its current status.

To understand the answer, first we need to understand another interesting fact.

Refreshing in Computer Monitors

To display a video, animation or anything, a monitor has to repaint its content frequently at about 60 times per second. It is known as monitor refresh rate. The standard refresh rate for a high-definition display is 60 Hz, means repaint content 60 times per second. Wow, did you know that?

Why a monitor needs to refresh its content 60 times per second and not 50, 40 or 30 times? Refreshing below 60 Hz produces flicker in picture. A higher refresh rate produces smooth picture and less motion blur. You can learn more about display terminology like Hz, HDTV, etc.

Standard Computer Monitor screen refreshes itself at 60 Hz means 60 times per second. It is known as Monitor refresh rate.

Flicker was  a major problem with CRT displays.

Here is the Answer…

Answer: Refreshing a computer is to refresh state of an operation in computer and show its current status.

To make it more simple, understand this with an example. When copying files from one folder to another, Windows regularly updates copied files on-screen.

Sometimes, due to performance reasons Windows disables this feature and user can’t see updated status of copied files. In that case you can use Refresh option from context menu to clear operation till now and refresh the current status.

You can Refresh the status on desktop screen and Windows Explorer by pressing F5 on keyboard.
