Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data.
The central processing unit (CPU) of a computer is what manipulates data by performing operations.In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but larger and cheaper options father away.Often the fast volatile technologies (which lose data when powered off) are referred to as ‘memory’, while slower persistent technologies are referred to as ‘storage’.
8 inch floppy disk
This 8 inch floppy disk was made by Memorex. A floppy disk is a disk storage medium composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with fabric that removes dust particles.The earliest floppy disks were developed in the late 1960s and were 8 inches (200mm) in diameter. The phrase ‘floppy disk’ appeared in print as early as 1970.Floppy disks were later produced in 5¼ inch (133mm) and 3½ inch (90mm) sizes and were a ubiquitous form of data storage and exchange from the mid-1970s well into the 2000s.
