The typical analog circuit that connects between the customer premises and the central office (phone company) has two copper wires. These wires are referred to as TIP and RING. There is typically a -48 VDC signal between the TIP and RING wires which is typically powered by the central office switch. When a standard analog phone is connected to the analog circuit and the handset is picked up (going off hook) a switch on the phone closes the connection between the TIP and RING wires and current is drawn from the central office switch. The switch determines that current is being drawn and provides dial tone so the person on the phone knows it is time to dial a number. A PBX FXO circuit running loop start looks like a standard analog phone to the central office switch. Now, one problem that is often seen with loop start circuits is a condition called "glare". Glare occurs when a call comes in on the analog line from the central office at the same time the PBX wants to seize the same line to make an outgoing call. The ground start protocol was designed to eliminate this problem with glare. From the PBX side, the RING lead is grounded first, then the central office circuit must ground the TIP lead before the PBX can close the loop between TIP and RING.
That a loop is curved and a whorl is shaped like a wave.

The difference is that pre means before and post means after in Latin so it's tested before or after. :)
foreach loop executes a predetermined number of times eg. list of items, rows in a table, etc. a for loop executes until a certain condition is met
Deterministic and non-deterministic loops A deterministic loop is predictable. The number of iterations of such a loop are known in advance, even before the loop has started. Most counting loops are deterministic. Before they start, we can say how many times they will execute. A non-deterministic loop is not easily predicted. A loop that is driven by the response of a user is not deterministic, because we cannot predict the response of the user. Non-deterministic loops usually are controlled by a boolean and the number of iterations is not known in advance.

the counter variable cannot be initialized in while loop before entering into the block.
A Loop pedals recorded sound does not fade (decay).
The 'break' command will stop a loop from going any further, where a 'continue' command will start the loop over at the top (or bottom) of the loop, bypassing other instructions that may be in the loop. The 'continue' command will not stop a loop, but a 'break ' command will.Note: these statements aren't commands or functions.
Ground loop current, which is undesirable and every effort should be made to eliminate it.

loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
no difference that's the difference
You mean PL/SQL? Well, they are different things, read the manual for details.
you have a ground loop, use a ground loop isolator to get rid of it.
No difference.
