The first 8-inch floppy disks created in the 1970s had a capacity of 80 kilobytes. By 1986, IBM improved its design, resulting in the 3.5-inch floppy disk, which had a maximum capacity of 1.44 megabytes.
The smallest format of a floppy disk can hold 79.75 kilobytes, while the largest capacity of a magnetic floppy disk stores 2.88 megabytes. The storage capacity of a floppy disk depends on the type of the disk being used.
A floppy disk is covered with iron oxide, a magnetic material, and the floppy drive records information on the disk by magnetically rearranging the material. The drive reads the data on a floppy disk by sensing the arrangement of the magnetic coating and translating it into computer code.
Floppy disks were introduced in the late 1960s and early 1970s. Initially, they were 8 inches wide, although this quickly was reduced as technology developed.
Since 1969, there have been three different size floppy disks for computers, each one with different storage limits. The most recently used disks have a hard plastic cover measuring 3.5 inches by 3.5 inches. It can hold up to 1.44 MB of data.
As of 2015, the average range for a hard-disk on an entry-level computer is between 320 GB and 750 GB. As the computer increases in specifications, so does the amount of hard drive space. Larger computers can have up to 10 TB of space on their hard drives.
According to HowStuffWorks, a floppy disk is used to store computer data on a medium that exists outside of the computer. Before high-capacity online and offline storage solutions became widely available, floppy drives were a simple way to store and distribute information.
To format a hard drive in Windows 7, access the Disk Management section via the Computer Management utility, locate the disk you wish to format, and choose the Format option from the context menu. Specify the parameters regarding the file system and allocation unit size, and initiate the process.
A local disk drive is a data storage device inside a computer that holds the operating system; software; and files, such as images, music, movies and documents. Hard disk drives store data as bits, zeros and ones, on a stack of plates coated with magnetic material. As the plates spin, a magnetic hea
The main purpose of a hard disk drive is to operate as a storage device for data. A hard disk stores data internally by recording it on metallic plates that are charged electromagnetically. As of 2015, hard drives can store many gigabytes of data.
