A decade resistance box is piece of laboratory equipment that allows the user to dial in a precise amount of electrical resistance to be inserted into a circuit. For example, it might have a dial for 100s of Ohms, 10s of Ohms, and 1s of Ohms, and allow the user to set any value from 999 Ohms to 0 Ohms in 1 ohm steps. While the use of this device has probably been largely superseded in laboratory use by more sophisticated equipment, it was used in the past in some or all of the following applications: Measurement of unknown resistances by the "bridge" method, Setting the current in a test circuit, Calibrating other lab equipment such as an Ohmmeter or Ammeter, Demonstrating Ohm's Law, and so on.

even a six year old knows this so i am going to leave you on suspence:)
Client/server applications
Scientific Computer Applications was created in 1969.
what do they mean when they say close all applications on the computer
Resistance decade box is nothing but Resistance bank. It has various ranges of Resistance value ranging from few ohms to few mega ohms. In other terms, large value of resistance are fabricated in single box is said to be Resistance decade box.
we use it when we require a variable resistance in a circuit
The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.
A box of precision resistors where you can dial in the exact resistance you want with dials. Essentially a variable resistor with very precise, discrete, settings.
same as decade resitance box but instead of reitances there wil be capacitances

a box which has resistance between 1 ohm to 50000 ohm
It is used to dial in a specific resistance within the range of the box. It can be used wherever you need a resistor of an unknown value or a precise value. Most decade boxes provide reistance with .01% of the desired resistance. I've used them to balance a wheatstone bridge that had a tiny mV offset.
to measure unknown resistance
reduce distortion,
It depends on what you want to accomplish. If you want to decrease the resistance in a circuit, you would place the box in parallel to some other resistor. If you want to increase the resistance in a circuit, you would place the box in series.
