I have read in forums and googled results , that 'Refresh' is not needed in Linux (Ubuntu /Linux Mint , etc ) like systems.
I never found the reasons or concept behind REFRESHING in Linux.
What exactly does refresh means in Linux, I am aware that 'F5' / 'Ctrl+R' keys work and doesdo a refresh kind of operation in Linux OS, but what exactly does it do.
And also why there is no need of 'Refresh' in Linux , if it is there then Why.
