CPU, the central processing unit, can take and understand instructions and output a result according to its instructions. A core component of a CPU is the APU, an arithmetic processing unit, this is responsible for all mathematical calculations and comparisons. <span />
<span>Ordering of tuples in a Relation : </span>The tuples
are not considered to be in order, even though they appear to be in the tabular
form. The Ordering of attributes in a relation schema R and of values
within each tuples - We consider the attributes in R(A1, A2, .., An) and the
values in t=<v1, v2, .., vn> to be in order. Values in a tuple : All values are considered to be indivisible (atomic). A
special null value is used to represent values that are unknown or not applicable
to certain tuples.
Answer:
Definition, Prototype
Explanation:
A function prototype is the one who declares return type,function name and parameters in it.
<u>Syntax of function prototype
</u>
returnType functionName(type1 argu1, type2 argu2,...);
Function definition contains the block of code to perform a specific task.
<u>Syntax of function definition</u>
returnType functionName(type1 argu1, type2 argu2, ...)
{
//body of the function
}
Whenever a function is called, the compiler checks if it's defined or not and control is transferred to function definition.
So,it is necessary to define the return type and parameters of the function.
Answer: Its a method of transferring data between the CPU and a peripheral, such as a network adapter or an ATA storage device. Each data item transfer is initiated by an instruction in the program, involving the CPU for every transaction.
Explanation: idk if this helps but hope it does
