Computed columns in SQL are calculated columns where the value of the column will be automatically inserted according to the formula specified.  

Suppose Net salary = Gross_salary – PF, so this can be created as,

Create table Employee(empno, empname, Basic, HRA, PF, Gross_Sal = Basic+HRA,Net_salary = Gross_salary-PF)

When you query Select * from Employee, all the fields along with the calculated column values will get displayed. Even if you update on the field, changes will be automatically done in calculated column.

The programmer.

The CPU (central processing unit or simply the processor) is the brain of the computer system, it processes data at a very fast rate depending on it's processing speed. But it only relates to speed of data processing and a link between components of the system.

What are the advantages of mine shaft gear and the disadvantaged​
romanna [79]

Answer:

One sheave means that you are using a single drum winder. They are the worst! Double drum winders control easier, brake better and are much more efficient. They save time ( two skips or cages) and can be clutched to perform faster shift transport. A single drum is slow, unbalanced and can be a nightmare if it trips out during hoisting. If the brake system is not perfect it can be a real hairy experience. For a runaway single drum, there is no counterbalance effect. It always runs to destruction. With a double drum, the driver still has a chance to control the winder to a certain extent and he has two sets of brakes to rely on. A single sheave could also mean a shaft with a single compartment. No second means of escape unless there are ladders or stairways. Not a very healthy situation.

Those are just a few points. I am sure much more can be said in favor of a double drum winder and two or more sheaves in the headgear. Most of the shafts I have worked at have multiple winders and up to ten compartments. They all have a small single drum service winder for emergencies and moves of personnel during shift times. They are referred to as the Mary - Annes. Apparently, the name originated in the U.K. where an aristocratic mine owner named the first such winder after his mistress.

The question above has multiple choices as below;

<span>a.      </span>Wear aggregation.

<span>b.      </span>Wear mitigation.

<span>c.      </span>Wear prevention

<span>d.      </span>Wear leveling

The answer is d) Wear leveling.


This technique by some SSD controllers to increase the memory’s lifetime is called wear leveling. The mechanism for this principle is simple: distribute the entries for all the blocks evenly so that they will wear out evenly. Flash controller typically manages wear leveling and uses a wear leveling algorithm to control which physical block to use.
