Answer:
Option A is the correct answer choice for the above question.
Explanation:
The computer system needs intercommunication which is done inside the processor to process the task given by the user. There are two types of model is used for intercommunication--
- Message passing and
- Shared memory
The difference between two is that message passing passes the message on two points at a single unit of time whereas shared memory simultaneous shares the multiple messages. That's why shared memory is faster than message passing.
- Hence option A is the correct choice because it also refers to the above concept. While the other is not correct because--
- Option B states that message passing is faster than shared memory which is wrong.
- Option C states that message passing is used for large data but shared memory is used for large data.
- Option D states that shared memory is unavailable in some processor which is wrong.
Answer: Multiplexing
Explanation:
By using the multiplexing technique we can easily use the multiple digit display in the input pins of the hardware. We can use this technique to display the several digits and the extra hardware is require which is proportional to the number of several digit to be display.
As, hardware use only limited number of input and output pins. Therefore, multiplexing is the technique used the number of hardware chips need for multiple digit display and can be minimize using this technique.
I can not understand your question, about it. What is homework of Gustavo working in, Visual or Dev C++ with any language?
