Ques 49. What is File?
Ans. A file is a long sequence of bytes which represent data. Each file has a name and an extension which are separated by a dot (a period). The name, of course, identifies the file. The extension tells the computer what type of data is contained within the file. For example, a file called "Letter to George.DOC" is a Microsoft Word DOCUMENT. The file you are reading now is called "glossary.html". HTML stands for HyperText Markup Language, and it is the file type for web pages.

Ques 50. What is Floppy Disk?
Ans. A round, flexible piece of magnetic media stored within a 3.5 inch square protective plastic case. One floppy disk can store 1.44 megabytes of data. Because floppy disks use magnetic media, they must be kept away from magnets, or the data on them could be erased! Computer speakers are magnetically shielded to prevent erasure of floppy disks, but standard speakers are not!
