Give two examples of computer related scenarios that exemplify:
a) Abstraction (two examples)
b) Virtualization (two examples)

Please show your detailed work! Thank you.

Solution

a.) Abstraction means hiding the unnecessary details that are not required. For example, website developer doesn\'t show real code they used for developing the website.

Another example for abstraction is the database implementation, the user which query the data see only the interface, user is not allowed to see the implementation data.

b.) Virtualization:

Now-a-days, cloud computing which creates a boom in the IT industry is actually based on the virtualization. People install their systems on the virtual cloud and use the various services provided by the vendor companies without worrying about their actual implementation details.

Another example of virtualization is computer memory as main memory by operating system. In case of shortage of main memory, operating system use some portion of secondary memory as main memory to speed up the processes.
