Answer:

file subversion

Explanation:

File subversion is compliant with the copy-modify-and merge model. Here, users make personal working copies which they can adjust concurrently. After the adjustments, the files are merged into a final copy by the version control system or someone.

This is similar to the version control process of Leslie's company. The team members all save their altered versions of the files which are then finally merged into one final file.

Which threading model is best for achieving true parallelism and how?
WITCHER [35]

Answer:

The explantion of this question is given below in the explanation section.              

Explanation:

Parallelism means that an application is split into smaller subtasks that can be processed in parallel on multiple CPU at the same time. Parallelism is related to application handling individual tasks on multiple CPUs. To achieve true parallelism your application must have more than one thread running, schedule the task into other threads, graphics cards, and CPU, etc.  

It is noted that parallelism is a concept while multiple threading in computer programing is its implementation. Some operating systems provide a multiple threading that combined the user-level thread and kernel-level thread facility. In such a system, multiple threads within the same application can run in parallel on multiple CPU or processors

There are three types of Multithreading Model

• Many to many relationships.

• Many to one relationship.

• One to one relationship.

Many to many relationship

This model multiplexes any number of user threads onto an equal or smaller number of kernel threads. However, this model provides the best accuracy to concurrency. However, using this model, true parallelism can be achieved, if the system has multiprocessor.  

Many to One model

This model maps the user-level threads to one kernel-level thread and its management is done in userspace by the thread library. In this model, only one thread can access the Kernal at a time, so multiple threads are unable to run on multiple CPU in parallel.  

One to one relationship

This model provides one to one relationship between the user and kernel-level thread. This model is better than the many-to-one model. It allows another thread to execute when a thread makes a blocking system call. However, it supports multiple threads to execute in parallel on the microprocessor. This model provides true parallelism.

Fill in the blanks, so the print statement displays the result of the function call in order.
sergejj [24]

Answer:

Rep;ace the blank with

smaller, bigger

So, the complete line is:

smaller,bigger=order_numbers(100,99)

Explanation:

From the question, we understand that the program is to return the order of a number from least to highest

This has been well implemented in order_numbers function

Because the order function returns two values, the order_function must be called in order to accept two values and the syntax is:

<em>value1,value2 = function(return-value1,return-value2)</em>

In this case, the statement is:

smaller,bigger=order_numbers(100,99)

So, in the next line of the main, the values of smaller and bigger are printed:

<em>print(smaller,bigger)</em>
