Data Storage Technology Similar Eslpod Record Holes Machine

Technology "evolves" (changes over time) very rapidly, and there have been many recent "advances" (improvements) in "data storage technology" (ways to record information so that it is not lost).

One of the first types of data storage technology was "punch cards." These were "stiff" (not easy to bend) pieces of paper that had many holes "punched" (cut into something) into them, and the position of those holes controlled the behavior of a machine. For example, punch cards were used to control "textile looms" (machines that weave cloth) and to play "organs" (large piano-like instruments).

"Magnetic tape" was a major "milestone" (an important point in the progress of something) in data storage technology. Similar to a "cassette tape" (devices used to record and play music before CDs were invented), they use a long piece of magnetic tape that is "wound up" (rolled in a circle) and then unwound as it is "read" (viewed and interpreted) by a machine.

"Floppy disks" (were large, flexible plastic squares containing a metal "disk" (a flat circle) that could be read by computers. Over time, they became smaller and the littlest ones had a hard plastic "case" (outer covering).

Most of these data storage technologies have been replaced by "flash memory," which is used in "USB flash drives" (devices that plug into computers), "memory cards" or "memory sticks" (small devices that are placed in a cell phone or camera), and similar products.

Each "generation" (a group of items that use similar technology) of data storage technology "improves upon the last" (is better than the one that came before it), storing more data in less space, usually more quickly and less expensively.
