What is varistor and what it do?
A varistor is a "variable resistor". When its value changes it then changes the amount of electricity it drops. Some of the energy goes to do the job; some of the energy is "dumped" out as heat. How about this: the volume control on your radio is a varistor. A dimmer switch on your living room lights is a varistor.

Did varistor having polarity how you will place the component and how you will check the component status?
Varistors are not polarity sensitive. Now I'm pretty sure that the device in question is a varistor. I googled for SAS-820KD05, found several references but unfortunately no data sheet - maybe you have more luck. One main criterium for selecting a varistor is the varistor voltage - as long as the voltage applied to the varistor is below the varistor voltage, it will behave like a capacitor. When the voltage is above, e.g. caused by a transient, it acts as a resistor, shorting this transient. Another important value is the max. pulse current a varistor can withstand.

What is the use of metal oxide varistor disc in Lightning arrestor?
I think your answer is given in previous question -( correct size of varistor across 24v coil) I am just pasting the same here. . . "When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby. It renders the power strip useless. But the connected devices are usually spared. "
How do you determine correct size varistor on a 24vac coil?
is this coil a single shot solenoid or is it used as a filter i assume you want to know a good value for a varistor to stop voltage spikes from the reverse EMF which is aprox. 4X the input voltage. so i would say to use 2X-3X the input Voltage so 48 or 72 Volt MOV (Metal oxide varistor) You want the varistor to be several volts greater than the peak voltage of the signal across which it is connected. 24 volts is probably the RMS value of the coils voltage. Your varistor must be selected to be greater than the peak voltage. When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby.

What is a surge suppressor varistor?
A varistor is an electronic component used for surge suppression. It is also known as a voltage dependent resistor, but it acts more like two zener diodes reversed and placed in parallel. The majority of surge suppression devices use these. However, they don't work all that well for lightning strikes.
Asked in Computer Programming
What is a compiled program?
A compiled program is source code that is translated to either machine code (native code) or byte code. Native machine code requires no further translation and can be executed as-is, but byte code must be interpreted in order to produce the required machine code. Java is an example of a language that compiles to byte code that is suitable for interpretation by the Java virtual machine. C++, on the other hand, compiles to native machine code. Interpretation is much slower than executing native machine code program, however it is more efficient to interpret compiled byte code than it is to interpret high-level source code. Moreover, byte code is generally portable whereas native machine code is always machine-dependent.
