Input Buffering

/ˈɪn.pʊt ˈbʌf.ər.ɪŋ/

noun — “the art of letting user input pile up politely before the program grabs it.”

Input Buffering is a technique where data entered by the user or received from an external source is temporarily stored in a memory buffer before the program processes it. This allows programs to handle input efficiently, reducing the number of immediate reads from devices like keyboards, network sockets, or files, and preventing constant interruptions to the CPU.
