What exactly is the purpose of connection links straped between the rocket and the launch pad
$begingroup$
I am curious on what are those multiple connection cables latched between the rocket and launch pad.
What exactly is the purpose of it, I am aware that one should be for filling up the fuel. But what are the rest used for, and I wonder what makes those connections so crucial that they are not disconnected until the lift off.

Don’t forget that all the fluids and gases that went in might have to come back out if the launch is scrubbed. You don’t want to have to send somebody out to replug umbilicals into a fully-fueled rocket just because you unplugged them too soon before a scrubbed launch.

In general, umbilicals are provided from the launch pad to the vehicle for any services that need to be provided after the vehicle is installed on the launch mount, and to remove hazardous gases from the vicinity of the vehicle.
Consider that vehicles can sit on the pad for long periods if problems occur during the countdown. Many different consumables may need to be replenished. Use of ground supplied power and cooling conserves vehicle resources for flight.
Details vary, but will be similar for all vehicles.
For the Space Shuttle, the top umbilical arm (the "beanie cap") connected to the liquid oxygen tank vent at the tip of the External Tank, and carried oxygen vapors away from the vehicle.
The next arm down, which passes on the other side of the solid rocket booster in this picture, is the External Tank Hydrogen Vent and Intertank Access Arm...which does exactly as its name suggests.
The next arm down is the Crew Access Arm.
Most interfacing services on the Shuttle were provided by the Tail Service Masts, the gray tombstone-shaped structures to the left and right of the Orbiter tail. They supplied cold coolant, purge gas, liquid oxygen, liquid hydrogen, gaseous nitrogen and gaseous helium, and returned warm coolant, recirculated liquid oxygen and liquid hydrogen to the ground facilities. Sense line connections for the leak detection system were provided. They also supplied connections for electrical power, communications, and data.
Here is a schematic of one of the T-0 umbilicals showing the various connectors and a list of the services provided through them. I haven't found a list for the other umbilical but it was very similar.

Nice answer! Would it be worth including a Saturn V picture to show how many umbilicals might be necessary without something like the Tail Service Masts?

@OrganicMarble I'll see if I can find the notes from when I was working on a LUT model for my SV rocket. I'd compiled what the pipes on each arm were for from engineering diagrams hosted by the LUT yahoo group. (Mostly I needed to know which set of pipes I needed to connect to on the tower.)

I've a suspicion no-one is using wireless telemetry on the pad, beyond ensuring the link is operational as go-no-go step. But modern technologies like ethernet replace a lot of wiring to analog sensors.
