Answer:- Major property of a good hash code is that objects which are equal should return the same hash code .
Explanation: Hash codes is a numeric value which is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable.

Available options
=A4&&B4
=A4&" "&B4
="A4"&""&"34"
=A4&""&B4
Answer:
=A4&""&B4
Explanation:
In a Microsoft Excel spreadsheet, to combine the content of two cells into another cell, a user will have to use the command &
Hence, in this case, given that there is no need to have any character or blank space in between the content of the starging cells, which is just A4 and B4, then we have the following technique
1. Select the cell C2
2. Input the command = or +, then select cell A4
3. Input the command &
4. Then select the cell B4
5. Click enter.
Therefore, the answer should appear as =A4&B4.
But from the available options, there is nothing like that, so we pick =A4&""&B4 because it gives the same outcome.

- OS(The Operating System) sends <em>interrupts to the processor</em> to stop whatever is being processing at that moment and computer architecture send <em>data bus</em>. This bus sends<u> data between the processor,the memory and the input/output unit.</u>
- The operating system is a low-level software that supports a <em>computer’s basic functions</em>, such as <u>scheduling tasks and controlling peripherals</u> while the computer architecture has the <em>address bus bar</em>. This bus carries <u>signals related to addresses between the processor and the memory.
</u>
- The interface between <em>a computer’s hardware and its software</em> is its Architecture while An operating system (OS) is<u> system software that manages computer hardware and software resources and provides common services for computer programs.</u>
Explanation:
In short explanation,the Computer Architecture specifically <em>deals with whatever that's going on in the hardware part of the computer system </em>while the Operating System is the computer program <em>which has been program to execute at some instances depending on the programming instructions embedded in it</em>. An example is the MS Office.
