Answer:
It is the ALU or the Arithmetic Logic Unit.
Explanation:
It is the ALU. However, keep in mind that registers and buses do a very important task. The number of registers we have, faster is the processing, and the opposite is true as well. And there is a reason behind this if we have different channels for sending and receiving the data from the memory, and several registers for storing the data, and we can formulate the requirement seeing the requirements for full adder and half adders. Remember we need to store several variables in case of the full adder, and which is the carry, and if we have separate registers for each of them, our task becomes easier. Remember its the CU that tells the ALU what operation is required to be performed. Also remember we have the same channel for input and output in the case of Van Neumann architecture, as we have a single bus. and we also have a single shared memory. And Harvard architecture is an advanced version of it.
Answer:
Replace the first blank with:
message = "Hello " + name + ". Your lucky number is " + str(number)
Replace the second blank with:
return message
Explanation:
The first blank needs to be filled with a variable; we can make use of any variable name as long as it follows the variable naming convention.
Having said that, I decided to make use of variable name "message", without the quotes
The next blank is meant to return the variable on the previous line;
Since the variable that was used is message, the next blank will be "return message", without the quotes
Answer:
Option (d) is the correct answer.
Explanation:
An Array is used to store multiple variables in the memory in the continuous memory allocation on which starting index value is starting from 0 and the last index value location is size-1.
In java programming language the array.length is used to tells the size of the array so when the user wants to get the value of the last element, he needs to print the value of (array.length-1) location so the correct statement for the java programming language is to print the last element in the array named ar is--
System.out.println(ar[ar.length-1]);
No option provides the above statement, so option d (None of these) is correct while the reason behind the other option is not correct is as follows--
- Option a will prints the size of the array.
- Option b also gives the error because length is an undeclared variable.
- Option c will give the error of array bound of an exception because it begs the value of the size+1 element of the array.
Answer:
Deleting files and etc on your computer.
I = V/R. So the answer is 9/200 = 0.045A = 45mA which is B
