Varchar cuts off trailing spaces if given a shorter word than its declared length, while char does not. Char will pad spaces after it if given a shorter word.

What is the difference between char and varchar data types?
The CHAR datatype uses a fixed length, where as the VARCHAR datatype can be variable in length up to the maximum value specified for the length. If you insert "Hello" into a CHAR(10) field, the column would actually contain "Hello " with 5 trailing spaces. The same value inserted in a VARCHAR(10) field would contain "Hello". char datatype is fixed length data type and it store maximum 255 characters while varchardatatype store up to 4000 character of variable length datatype

Different between oracle datatypes char20 and varchar20?
In Oracle, the char(20) datatype is a fixed length character string. It will always use 20 characters in the block. If the value contained in the field is less than 20 characters, it will be padded on the right (or the left, depending on coding) with spaces. In Oracle, the varchar(20) datatype is a variable length character string. It will use betwen 1 and 21 characters in the block, 1 for the length, and 0-20 for the data. Its effective length can range between 0 and 20 characters. Note, however, that a string of length 0 is indistinguishable from a null value. This is a deviation from the SQL standard that Oracle acknowledges, but fixing it would break too much existing code. Note also that comparing a char against a varchar is problematic. With the trailiing spaces, the char is not the same as a varchar containing the same characters. Predicates involving these mixed types should use the rtrim expression on the char datatype. (Example: while rtrim(mycharvalue) = myvarcharvalue) Note also that varchar is obsolete. Current code should use varchar2, such as varchar2(20).

Difference between number and text type field in ms access?
This is true in any database (Access, Oracle). A number field is technically called a "NUMERIC" field. Only numbers can be inserted into a field that has this designator. A text field is for characters or numbers. It can be a "CHAR" (character), a VARCHAR (characters or numbers). It's basically a way of putting rules on columns--what type of data belongs there.
