A dual processor SMP system includes an L1 data cache for each processor and employs the MESI protocol to maintain cache consistency. Each cache is a 2-way set associative copy-back cache that contains a total of 8192 cache lines. All cache lines are 256 bytes in size. The ways within each empty set are filled from lowest to highest (way0, way1, etc.). A write-allocate policy is used for each cache. One software process, P1, runs on the first processor at the same time that another software process, P2, runs on the other processor. a) All caches are initially empty, so each cache line starts out in the invalid (I) state. P1 makes the first memory access by writing the value 80 to a variable X at address 0x400804C0. What set is affected in P1's cache and what is the final MESI state for the affected line? Explain your answer. b) After P1 writes X, P2 then writes the value 156 into a variable Y at memory address 0×400804 F8. What action should be taken for P1 's cache in response to the write by P2, and what is the final MESI state for any affected line in P1's cache? Explain your answer. c) What set is affected in P2's cache when P2 writes the value 156 into Y and what is the final MESI state for the affected line in P2's cache? Explain your answer.

The thing that happen to the patent awarded to Mauchly and Eckert is that the business was sold to Remington Rand in 1950. Remington Rand ultimately combined with Sperry Corporation to form Sperry Rand, which is still in business today as Unisys.

The ENIAC patent held by Mauchly and Eckert was declared invalid by the U.S. Federal Court in October 1973 for a number of reasons. Some related to the interval between the First Draft's publication and the patent filing date (1947).

The Electronic Numerical Integrator and Computer (ENIAC), the first general-purpose electronic digital computer finished in 1946, is said to have been credited to scientists such as John William Mauchly and J. Presper Eckert.

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

Organisms in a food web are related through producer/consumer, predator/prey, and parasite/host relationships. Because of these relationships, one population affects others through direct and indirect interactions. A direct interaction refers to the linear relationship between two organisms such as predator feeding on a prey (a lion eating a deer) while an indirect interaction is a type of relationship that occurs or is mediated through a third.

Explanation:

The third line of computer system development created problems in timing and synchronization that contributed to the development of the concept of the process: multiprogramming batch operation, time-sharing, and real-time computing. The concept of the process was developed due to the problems associated with these three lines of computer system development.

Multiprogramming batch operation is the simultaneous execution of two or more programs on a single processor. Each program is assigned its segment of memory, and the system switches between the programs. During this line of development, there was no synchronization of operations, and different users competed for the same resources, resulting in inefficiencies in computer use. Time-sharing is the sharing of a computer system's time among many users by a computer, and it involves allowing multiple users to access a computer concurrently. It is similar to multiprogramming, but it allows multiple users to interact with the computer simultaneously.

However, this line of computer system development faced timing problems due to the competition among the users for the same resources. Real-time computing is the processing of data immediately upon receipt. It involves processing data as they become available, and it is used in systems that require immediate response. This line of computer system development created problems in timing and synchronization that contributed to the development of the concept of the process, which refers to an instance of a computer program that is being executed by one or many threads.

A symbolic link, also known as a soft link, is a special type of file that serves as a reference to another file or directory. It does not contain the actual data of the target file but rather acts as a pointer to it.

When creating a symbolic link, it does not create a new file or directory; instead, it creates a link to an existing file or directory.If a file already exists with the same name as the symbolic link you are trying to create, the symbolic link creation will fail. This is because the file system does not allow two different files with the same name to exist in the same directory.To create a symbolic link, the target file or directory should not already exist with the same name. If you want to create a symbolic link with a specific name, ensure that no other file or directory shares the same name in the target location.

The statement is False.

This is because excel displays the value of a cell based on the number format applied to that cell. The value that is stored in the cell may be a precise value, but it may be displayed differently in the spreadsheet depending on the number format.

For example, if a cell contains the value 123456, it can be displayed as "123,456" if the number format is set to display numbers with a thousands separator. Additionally, when a formula results in a value that is very large or small, Excel will use scientific notation to display the value in the spreadsheet, even though the precise value is stored in the cell.

In addition to this, if a cell contains text, Excel will display the text as it is, even if the cell is formatted to display numbers.

It's worth noting that the value stored in a cell can be different from the value displayed in the cell, and it's important to understand the difference between them when working with Excel.
