KEYPUNCHING Meaning and
Definition
-
Keypunching is a process of inputting data into a computer system using a specialized device called a keypunch machine. It involves the manual entry of alphanumeric characters and symbols onto a punched card, which could then be read by a computer. The keypunch machine typically consists of a keyboard that resembles a traditional typewriter with additional keys for control characters and functions.
In the early days of computing, keypunching was the primary method of data entry. It required skilled operators who would meticulously punch holes in the appropriate locations on the cards, representing the desired characters or data values. Each position on the punched card corresponded to a specific code or character, which the computer could interpret.
The keypunching process involved carefully aligning the card and placing it on the machine's mechanism. The operator would then press the corresponding key for each character, causing a punch to create a hole in the card. Keypunching required accuracy and attention to detail to ensure that the correct characters were punched, as errors could cause significant problems during data processing.
With the advent of direct keyboard input and other advanced input methods, keypunching has become obsolete in most modern computer systems. However, it played a vital role in early data processing and was an essential skill for computer operators and programmers.
