Resistor tolerance is how accurate the resistor value is. You may have a 10% tolerance, 820 ohm resistor, which means the actual value of resistance is 820 ohms +/- 82 ohms. If you design a circuit that has very stringent requirements for resistor values, you may need to purchase a resistor that has a smaller tolerance (like 5, 2, 1, .5%). The smaller the tolerance, the more expensive it will be (generally).
on electronic components, of course, can not be made absolutely perfect. so there must be imperfections in the making, it is called tolerance. for ex: 100ohm resistor ,a tolerance of 5%, meaning the resistance between 95-105ohm (100ohm * + / -5%). not fit 100ohm.
The color bands on a resistor represent the resistor's resistance value. In this case, the colors brown, black, red, and gold correspond to the digits 1, 0, 2, and a multiplier of 10%, respectively. Therefore, the resistance of this resistor can be calculated as 10 * 10^2 ohms, which equals 1000 ohms or 1 kiloohm.
Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
100 megohm the 10 ohms completely vanishes in the tolerance of the 100 megohm resistor, in that range tolerances can exceed 20% of nominal.

The smaller the tolerance, the more expensive it will be (generally).
The minimum and maximum possible value is defined by the tolerance. To calculate the range of the resistor, simply add or remove the amount of the tolerance. For example, a 100Kohm resistor with 5% tolerance can range from 95Kohm through until 105Kohm. The lower the tolerance, the more accurate the resistor is.

A 1 ohm 20% tolerance resistor should not exceed 1.2 ohms actual resistance.
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
Yes, that looks right.

You don't, you read the tolerance markings. If you measure the resistor and it is outside the marked tolerance it is bad.
