Answer:
Open a file when the program needs to work with it and close the file as soon as you have finished using it.
Explanation:
In programming, we have some files that are stored in memory, or created in some other section of the program to save information.
<u><em>for example</em></u>, we want to save the data of a class or school faculty to create a database. For this purpose I need to create a file.
As the files that we will create may contains data, these files will utilize computer resources such as, memory (RAM, Cache) and other resources. While programming, we need these resources as well.
<em>Therefore, It is necessary to open a file when the program needs to work with it and close the file as soon as we have finished using it. The reason is that, it takes computer resources which are limited. </em>
Answer:
Operating system is the software that is used to control different hardware of computers and handle scheduled tasks.
It also handles the interrupts from some external devices, or from some software. The interrupts are handled through Interrupt service routine. When some external event occurs the following steps has been taken by OS to perform the operation
- In first step, an external event has been occurred, and request to the cpu to perform operation.
- This request invoke ISR (Interrupt service routine), to perform the operation.
- The interrupts are stored in stack on the priority basis.
- The CPU performs the operation on Interrupt as per request of ISR.
- After Completing operation, CPU return to its initial task.
