Techopedia Explains Read/Write (R/W)
One way to describe R/W is as an open, dual functionality, versus read-only. Examples of read-only include files or systems that are protected with a read-only attribute that prevents end users from changing them in any way. Another example is an e-reader device, where individual e-book files are generally read-only.
