The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.

Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.

quester [9]

Answer:

Hi there! The answer is C:

Explanation:

The scope of the LOWER function is limited to the select clause it is being used in. Outside of the select statement, the column will be returned as it is currently present in the database. Using the LOWER function will not automatically store data in lower case letters in the database tables. As an exercise, try creating a simple database table called "Employees" with columns "id" and "name". Then input a row using an insert statement with id as 1 and name as "BLAH". Try using the select statement with LOWER function and then without the LOWER statement.
