Differentiate between external and static variable?

External variable are those global variables which can be linked from other modules.

Static variables has programming scope of a file/module or inside a function. For example:

Sample.c
static int static_1;/*File Scope*/
int add_user(char *username)
{
  static int user_count = 0;/*Function scope*/
}

Static variables are restricted inside a file/module or inside a function by linker. It cannot be linked externally.
