Answer:
Explanation:
Hadoop clusters can boost the processing speed of many big data analytics jobs, given their ability to break down large computational tasks into smaller tasks that can be run in a parallel, distributed fashion.
Answer:
showProduct(int,double)
for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.
Explanation:
The code is
- <em>public static void showProduct (int num1, double num2){</em>
- <em> int product;</em>
- <em> product = num1*(int)num2;</em>
- <em> System.out.println("The product is "+product);</em>
- <em> }</em>
showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.
If showProduct( 10,10.0) is called the output will be 'The product is 100'.
Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.
This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
Answer:
Annotation symbol
Explanation:
A flowchart is a diagram that is used to show and represent a workflow, process or algorithm. Flow charts are used in designing processes or programs. Flow charts are usually designed using boxes and arrows.
An annotation symbol is a symbol used in flowchart to hold comments and it is usually represented by a three-sided box connected to the step it references by a dashed line.
Answer:
c. Both a and b
Explanation:
In computing, processing information simply means performing a task. It means transforming data from one form to another.
In the real sense of it, it means, performing arithmetic or logical operations (by ALU) on binary data which could result in transmitting data from input devices to output devices. When a user launches the calculator application on his PC, and he tries to do some arithmetic (which is processed by the ALU) by entering numbers using his keyboard/mouse (input devices), he gets the result on the screen(output device). This scenario is a typical example of processing information.
