Payroll systems accurately maintain data related to payroll processing. Familiarity with formal payroll systems and computerized software ensure the candidate has experience with current payroll technology.

This question illustrates whether the applicant has experience changing employee income tax withholding amounts. The applicant should be able to describe the necessary forms to use and the process for changing the information in the payroll system.

we can always fetch from one database and rewrite to another. Here is a nice solution of it.$db1 = mysql_connect("host","user","pwd")
mysql_select_db("db1", $db1);
$res1 = mysql_query("query",$db1);$db2 = mysql_connect("host","user","pwd")
mysql_select_db("db2", $db2);
$res2 = mysql_query("query",$db2);At this point you can only fetch records from you previous ResultSet, i.e $res1 – But you cannot execute new query in $db1, even if you supply the link as because the link was overwritten by the new db.so at this point the following script will fail
$res3 = mysql_query("query",$db1); //this will failSo how to solve that?

take a look below.
$db1 = mysql_connect("host","user","pwd")
mysql_select_db("db1", $db1);
$res1 = mysql_query("query",$db1);

$db2 = mysql_connect("host","user","pwd", true)
mysql_select_db("db2", $db2);
$res2 = mysql_query("query",$db2);

So mysql_connect has another optional boolean parameter which indicates whether a link will be created or not, as we connect to the
$db2 with this optional parameter set to 'true', so both link will remain live.

Now the following query will execute successfully.
$res3 = mysql_query("query",$db1);

Answer : C

Explanation:

Virtual circuits (VC)s are identified by DLCIs. DLCI values typically are assigned by the Frame Relay service provider. Frame Relay DLCIs have local significance.  A DLCI identifies a VC to the equipment at an endpoint. A DLCI has no significance beyond the single link. Two devices connected by a VC may use a different DLCI value to refer to the same connection.
