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 allow those chips to keep the data they are storing available. 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, this 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.
