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>
Kernal is the core of an operating system that maintains the computer’s clock, starts applications, and assigns the computer’s resources, such as devices, programs, apps, data, and information.
d. kernal.
<u>Explanation:</u>
Every operating system runs the operating system based on kernel instructions. Main or major role of operating system is kernel. If boot loader program fails to load kernel operation is missing the kernel we need to reinstall operating system or repair the operating system.
To display clock in the workstation or laptop or desktop, clock device driver been executed by kernel of operating system.
Kernel is core of any operating system, but kernel also controlled by operating system such as Unix etc.
The answer is D. It's asking for the most UNETHICAL not ETHICAL, the answer before me was ETHICAL. Sharing personal data is UNETHICAL.
the answer is they often contain biases :)
