Answer and Explanation:
Group by clause bunches every one of the information coming back from the question in the predetermined gatherings.
Order by clause will arrange the information either in rising or in dropping order depending on the section data or column data.
It is certainly a lengthy from execution perspective.
Envision that the quantity of columns returned by the question are millions and gathering and arranging information from this parcel takes bigger execution time.
The procedure is a lot of equivalent to on the off chance that you are approached to arrange the precisely coordinating names in a populace measurements, it requires colossal measure of handling time to make sense of the precisely coordinating names and after that arranging them as needs be.
The distinction between where and having clause:
'Where' and having clause in SQL are utilized to indicate separating conditions.
There is a little contrast between these two clause and is given as under:
WHERE clause is utilized while getting data (lines or rows) from the table, and the information which clears the condition will only be considered into the result set.
HAVING clause is later utilized to channel a data summary or gathered data.
On the off chance that the two clauses show up in SQL question, where clause will execute at first and afterward having clause is executed on the groups that returns the group clause.
Answer: an Arithmetic Logic Unit (ALU) that knows how to add numbers
Explanation:
The CPU can process those instructions easily, thanks to a control unit that knows how to interpret program instructions and an Arithmetic Logic Unit (ALU) that knows how to add numbers. With the control unit and ALU combined, the CPU can process much more complex programs than a simple calculator.
Answer: Option (A) is correct

Answer:
The following are the code in the Java Programming Language.
//set the for loop
for (k = 0; k < nMembers; k++)
{
//check that currentMembers[k] is equal to the memberID
if (currentMembers[k] == memberID)
{
//then, initialize isAMember to true
isAMember = true;
//and initialize the value of nMembers in k
k = nMembers;
}
//otherwise
else
{
//initialize isAMember to false
isAMember = false;
}
}
Explanation:
<u>The following are the description of the program</u>.
- Set the for loop statement that iterates from 0 and stops at the variable 'nMembers'.
- Set the if conditional statement that checks the variable 'currentMembers[k]' is equal to the variable 'memberID' then, initialize 'true' boolean value in the variable 'isAMember' and also initialize the value of the variable 'nMembers' in the variable 'k'.
- Otherwise, initialize 'false' boolean value in the variable 'isAMember'.
