What Are Storage Devices?
Introduction to Storage Devices
- In 1947, the Williams tube was introduced as a significant advancement in storage technology, with a capacity of 0.0625 KB, comparable to a very short text document today.
- The importance of storage devices is highlighted by their role in managing information and files on computers, making basic tasks like data backup feasible.
Types of Storage Devices
Optical Media
- Optical media are read using a high-precision laser beam; common examples include CD-ROMs, DVDs, and Blu-ray discs.
- A key limitation of optical media is their relatively low storage capacity compared to the data consumption needs of individuals.
Magnetic Media
- Magnetic media remain widely used due to their ability to handle large volumes of data; examples include hard drives, floppy disks, and DAT tapes.
- The first hard drive created by IBM (model 350) had a capacity of 4.4 MB, which is roughly equivalent to one MP3 song today.
