Primary key is the key that is actually chosen, for example a social security number.
There is also a unique key, say our finger prints! they also uniquely identify humans, but usually we prefer to use social security number when we list people (a unique key could be a primary key if we chose so)

"Why the computer is called diligent
Versatile machine"
Computer is called versatile machine because it is used in almost all the fields for various purposes.Because it can perform the task repeatedly without loosing its speed and accuracy for a long time.They are versatile because they can be used for all sorts of task.They can also do many of the same tasks in different ways.Computer is the electronic device which perform the logical and mathematical calculation.Computer is known as the versatile machine because it is very fast in every field and its part of life without it was cannot imagine life.
It can do the work faster and in every field the computer is used for making their work faster.
It can perform the work fast so it is called versatile machine.
Advantages of versatile machine:
- Computer are very fast due to which thousand of job can be performed within the short period of time.
- Complex mathematical problems and logical operations can be solved by using this computer.
- As computer is versatile device,multiple task like communication,graphics,documentation can be done.
Disadvantages of versatile machine:
- Computers are machine hence they have no brain so they work according to the program instruction set inside it.
- It is an electronic deice and it uses electronic sources to work,So it is very risk to store data and information on the computer independently because some electric and electronic damages may damage the data.So we have to make regular backup of the data.
