Cards were a fixed size. They were limited to 80 characters per card, so abbreviations were commonly used. This was one of the issues with the Y2K transition, years had been abbreviated with two characters instead of 4.
A program had to be written into the computer through the cards. Each card represented a line of code. If a program had 1000 lines of code, that was 1000 cards that had to be punched out on the machine, and kept in order. If you dropped them, it took forever to resort them.
Cards might not feed into the reader correctly, particularly if the weather was humid or damp. A bent card might jam up the machine, destroying some of the other cards, resulting in having to re-punch the cards.

What are punch cards?

What is Jacquard's loom?
The Jacquard loom is a mechanical loom which was invented in1801 by Joseph Marie Jacquard. The loom is controlled by cards with punched holes, and creates complex woven textile patterns such as brocade, damask, etc. It was the first machine to use punched cards to control a series of operations and the operator could change the pattern of the weave by changing to different cards. Each hole location on a card corresponds to a hook which can either be raised or lowered depending on whether the hole is punched out left solid. The hook raises or lowers a thread harness, which carries and guides the warp thread so that the weft will either lie above or below it, the sequence of raised and lowered threads creating the pattern. Modern jacquard looms are controlled by computers instead of punched cards, and may have thousands of hooks.

Why do you use keyboards?
Because the computer can't read my thoughts and I need some way to tell it what I want it to do. When I first started using computers you used punched cards to do that and the keypunch that punched the cards had a keyboard but was not connected to the computer. You punched the deck using the keyboard on the keypunch, then took the deck to the computer's card reader.

What is electronic punch card system?
An electronic punch card system was the first data entry system for computers. Cards were punched with holes according to the information that was stored or directions for the computer. The card was inserted into a card reader and the data was collected. Factories still use a type of punch card system with their manual time cards.
