variable_set('variable_name','value') --> set the variable name and
its value in table {variable} and makes it accessible via
varialbe_get()

//from bootstrap.inc
<?php
function variable_set($name, $value) {
  global $conf;

  db_lock_table('variable');
  db_query("DELETE FROM {variable} WHERE name = '%s'", $name);
  db_query("INSERT INTO {variable} (name, value) VALUES ('%s', '%s')",
$name, serialize($value));
  db_unlock_tables();

  cache_clear_all('variables', 'cache');

  $conf[$name] = $value;
}
?>


drupal_get('variable_name','default_vaule') --> this function will
check the table named {variable}
 for  variable if its found it will take its value otherwise
default_value will be taken

//from bootstrap.inc
<?php
function variable_get($name, $default) {
  global $conf;
  return isset($conf[$name]) ? $conf[$name] : $default;
}
