signed: its value can be less than zero
unsigned: its value cannot be less than zero
example:
16 bit signed: -32768 .. 32767
16 bit unsigned: 0 .. 65535
The primitive data types in C include:[signed|unsigned] char[signed|unsigned] short[signed|unsigned] int[signed|unsigned] long[signed|unsigned] long longfloatdoublelong doubleEnumerations (enum) and arrays may also be considered to be primitive types.
Data is stored in databases. To make the database more efficient, different types of data are usually classified as a certain 'data type'.
"int" is the abbreviation for an integer data type. In Java an int is specifically a 32-bit signed integer.
C datatype can be categories into two part 1) Scalar data type 2) derived data type.. The scalar data type is also called basic data type they are int char float double long signed or unsigned are key word which effectively change the storing power of these data type. by default they are signed in nature..

no
No, not always. It depends on the type of data you collect. If it is quantitative data, you will be able to calculate a mean. If it is qualitative data, a mean can't be calculated but you can describe the data in terms of a mode.

The answer depends on the type of data. The mean or median are useless if the data are qualitative (categoric): only the mode is any use. The median is better than the mean is the data are very skewed.
Unsigned int does not have a sign, meaning that it can be zero or a positive number in the range of data type (int). Signed data has a sign and can be positive, zero or negative.
