3. Character and String
The 'character' data type is able to store a single letter, number or symbol such as 'A', 'b', $, 4.
Using the character data type is very efficient in terms of memory as a character is stored either in a single byte (8 bits) or a single word (word length depends on the cpu type) depending on the computer system.
String data type
Characters are strung together to form words and sentences. It is convenient to treat these as a single variable the data type for this is called 'string'.

Note: Telephone numbers are stored as a string rather than an integer data type because an integer data type will remove any leading zeros from the number, thus 01926 becomes 1926. Also, no mathematics are likely to be carried out on such numbers.
