A refresh may refer to any of the following:

Refresh1. In general, refresh is another way of describing the process of reloading or updating what is being displayed. For example, if you were on a certain website, refreshing the page would bring up the most recent content published on that page. Essentially, you're asking the site to send your computer the newest version of the page you're on.

2. The refresh button, also know as refresh option, is a function of all Internet browsers. It is used to ask the browser to send you the most updated version of the page you're currently on. See the browser page for additional information about this term and related links.

Tip: On a Windows-based computer, pressing the F5 function key will refresh the web page being viewed on all browsers. Sometimes this key is referred to as the refresh button on the keyboard. The refresh button may also be a button in the browser that resembles one or two arrows going in a circle, like the picture shown on this page.

Tip: Pressing the F5 function key can refresh the Windows desktop screen.

Tip: On a Mac, pressing Command+R will refresh the page you are currently viewing.

3. Refresh is a term that describes the process of renewing the screen contents on a CRT monitor. As the refresh rate increases, the image becomes clearer.

We recommended that anyone who still uses a CRT monitor to have it set to at least a 75 MHz refresh rate. Lower refresh rates commonly cause strain on the eyes. If you have a flat-panel display, you do not need to worry about the refresh rate.

4. When referring to computer memory, refresh refers to the recharging of dynamic RAM (DRAM) chips that allows them to keep holding the data they are currently storing. Memory refresh rate is commonly displayed as xK, where x is a number such as 2 or 4. If the memory has a refresh rate of 2k, it indicates how many rows it takes to complete the refresh. In our example of 2k, this means there are 2 thousand rows. The refresh cycle is a way of showing the time it requires to complete one row.

5. Refresh may also refer to a software utility developed to help improve the performance of how memory is handled on a computer.

6. When referring to a computer battery, refresh is an ability that allows Ni-Cad batteries to reset the memory that stores their charge state.
