![]() Most of the storage devices mentioned above are no longer used with today's computers. To move the information to another computer, save it to a removable storage device, such as a USB flash drive. By default, most information is saved to your computer hard drive. When saving anything on a computer, it may ask for a storage location, which is the location information is saved. Today, we have smartphones that have hundreds of times the capacity at a smaller price that we can carry in our pocket.Įach advancement of storage devices gives a computer the ability to store more data, and save and access data faster. The first hard disk drive from IBM cost $50,000, was only 5 MB, big, and cumbersome. After floppy diskettes were released, they were replaced by CD-ROM drives, which were replaced by DVD drives, which were replaced by flash drives. When new storage devices are designed, as people upgrade to those new devices, the older devices are no longer needed and stop being used.įor example, when punch cards were first used in early computers, the magnetic media used for floppy disks was not available. Because people need more and more space, want it faster, cheaper, and want to take it with them, new technologies have to be invented. ![]() Why so many different storage devices?Īs computers advance, the technologies used to store data do too, with higher requirements for storage space. Even a task, such as browsing the Internet, requires information to be stored on your computer. Without a storage device, a computer cannot save or remember any settings or information and would be considered a dumb terminal.Īlthough a computer can run with no storage device, it would only be able to view information, unless it was connected to another computer that had storage capabilities. In the picture is an example of a woman entering data to a punch card using a punch card machine.Ī hard copy is considered a form of paper storage, although it cannot be easily used to input data back into a computer without the aid of OCR. Today, these forms of storage are rarely used or found. Storing data online and in cloud storage is becoming popular as people need to access their data from more than one device.Įarly computers had no method of using any of the technologies above for storing information and had to rely on paper. USB flash drive, jump drive, or thumb drive.Solid-state storage (flash memory) has replaced most magnetic and optical media as it becomes cheaper because it's the more efficient and reliable solution. This technology is found mostly on extremely large HDDs or hybrid hard drives.Īnother common type of storage is optical storage, which uses lasers and lights as its method of reading and writing data. Today, magnetic storage is one of the most common types of storage used with computers. Below is a full list of all computer storage used over the evolution of the computer. Today, there are three types of media used to store computer data: magnetic storage, optical storage, and solid-state storage. Are storage devices input and output devices?.What storage device has the largest capacity?.You will find a specimen of this license on the Copyleft Attitude site as well as on other sites.
