COMPUTER FUNDAMENTALS

Detailed explanation-1: -The first 8-inch floppy disk had a storage capacity of about 80 kilobytes. By 1986, IBM introduced the 3-1/2 inch floppy disk with 1.44 megabytes of storage space. This may seem like very little now, but at the time it was hard to imagine needing more space than that.

Detailed explanation-2: -In the middle of 1970s, a 5.25 diskette was introduced. Today, the most commonly used floppy disks are 3.5 inches and have the capacity of 800 KB to 2.8 MB (with a standard of 1.44 MB).

Detailed explanation-3: -Floppy disks store much less data than a CD-ROM disk or USB flash drive. A normal 31⁄2 inch disk can store 1.44 megabytes of data. This is usually enough for simple text documents.

Detailed explanation-4: -The correct answer is A. A double-density 3.5-inch floppy disk has a storage capacity of 1.44 MB.

Detailed explanation-5: -If you were to use the conventional base 2 or 1, 024 KB to figure out the capacity of a floppy diskette size, it would be 1, 474, 560 bytes.
