Punch cards have many names, they can be called “Punched Cards”. With reference to the discovery of Punch Cards, they are also called Hollerith Cards or IBM Cards since Herman Hollerith was the founder of IBM. Punch cards can be described as
“A set of paper cards in which a number of holes are punched by means of a machine or manually by hand to represent codes and data related to computers and programming”
The primary use of punch cards could be summed up as storage of information and other data during the days of early computers. These cards could be installed in a card reader machine which would convert the sequence of these holes into information that could be used digitally.
For instance, in the days of ancient computers, a person who used to program computer codes would write code manually in a handwritten form. The handwritten program or computer code would be later converted into punched cards by means of a punch card machine. The set of punch cards was then used to create a computer program or means of a card reader which could interpret the information on the card as digital information.
History of Punch Cards
The history of punch cards dates back to 1725 when they were initially used in the textile industry. It is quoted that Joseph Marie Jacquard used to create portraits woven in silk by means of these punch cards. With the passage of time the cards started becoming popular and by 1832 Semen Korsakov started using punch cards to save information and search data.
In 1890 Herman Hollerith introduced a method by which punch cards could be used as instruments to record information and store data by means of a punch card reading machine. These punch cards were used for recording data during the US census. Later when Hollerith founded IBM, a software & computer development company they went popular by the name of IBM cards.
How to use a Punch Card:
A punch card looked like a cardboard sheet with lots of holes in it on each column. The holes in each column were arranged in a manner that each sequential column represented a character such that each card developed a single line of code. In this way, a whole code or program was developed on the cardboard the punch card stored the information. Since each card could only be used in a limited manner, in order to develop a whole program or store a code, a whole set consisting of many cards as required.
In order to read and input the data on the punch card and load the computer program, the card was placed inside a card reader, installed on the computer. When the card is installed in the reader, the punch card reader starts reading from the left side at the top of the card. Going downwards vertically, from the top of the card to the bottom. Column after column the reader moved across the cards to interpret information.
The top of the card said what each card contained so that it could be understood what was saved and stored on a certain type of card. In the case of errors and omissions, the whole card must be printed again. The code on the punch card was similar to the binary system.
In the early days of computers, the old devices were not advanced enough to store and process large amounts of information like the devices of modern times. In order to save information and store, essential programs punch cards were used. The use of punch cards diminished after the development of magnetic strips. Punch cards were a primary storage device in the early 1900s which were later replaced by modern means of storing information by the 1960s.
Importance of Punch Cards:
Punch Cards were a cheap mean and reasonable device since
Input Of Data & Information:
Punch cards we primarily used to put data in the mainframe computers. Punch cards were one of the primary methods of storing and retrieving data
Storage Of Information:
The punch card was an effective way to save information in the early times. This was an efficient mean of editing updating and replacing information
Output Of Information
Sometimes the punch card would be used as a source for generating output, which would be later used by other programmers to process and develop different programs.
