Most people believe that the terms "data" and "information" are interchangeable and mean the same thing. However, there is a distinct difference between the two words
Data is raw, unanalyzed, unorganised, unrelated, uninterrupted material which is used to derive information, after analyzation On the other hand, Information is perceivable, interpreted as a message in a particular manner, which provides meaning to data. Data is the collection of raw facts and figures. It is without any proper meaning. Data may be collection of words, numbers, graphics or sounds. Examples of Data Student Data on Admission Forms When students get admission in a college. They fill admission form. This form contains raw facts (data of student) like name, father’s name, address of student etc. INFORMATION Processed data is called information. When raw facts and figures are processed and arranged in some order then they become information. Information has proper meanings. Information is useful in decision-making. Actually we process data to convert it into information. Examples of Information Merit List After collecting admission forms from candidates, merit is calculated on the basis of obtained marks of each candidate. Normally, percentage of marks obtained is calculated for each candidate. Now all the candidates names are arranged in descending order by percentage. This makes a merit list. Merit list is used to decide whether a candidate will get admission in the college or not.

Some computers may still have these, but back in the older day, the A: and B: drive were reserved for use as Floppy Disk Drives. The reason you might not have heard of these drives is because all big computer fabricators generally stopped including them on personal computers in 2003.
It was common to have two drives, hence why A & B are reserved. This is because of drive incompatibility, there wasn’t a set standard at the time and so you had to be prepared to read media that was formatted differently. It's not that computers don't have B drives. Initially, (hardly two decades ago), personal computers didn't have hard discs they were equipped with two floppy drives called drives A and B. Later, a hard disk was introduced and was labelled as the C drive. Other drives like the CD drive, DVD drive, flash drive and others were labelled D, E, etc. If you have a computer having two floppy drives, then they are called A drive and B drive. Source:Internet |
