A printer that is printing a set of documents would perform best utilizing a single-threaded process. In this instance, the printer is developing the documents in the order they were queued. There is no need to have additional threads added to the process because the printer is only going to allow the documents to print in order. This example may be different if the printer could print several jobs at once because the printer would need to assign specific jobs to certain print heads and may even need to add custom finishes to certain documents.
An application that allows the graphical user interface (GUI) to remain responsive while processing a large number of files would best be done utilizing a multithreaded process. The reason this example needs to be conducted with a multithreaded process is because the main thread is being used to process the large number of files. At the same time the files are being processed an additional thread is needed to ensure that the GUI remains responsive to other requests. Silberschatz et al. 2014 states that "If a process has multiple threads of control, it can perform more than one task at a time." Thus, making this a perfect example of multithreading.
A Python webserver that listens for requests, reads them, and pushes the data in the database would best perform utilizing a multithreaded process. Multithreading is used best in this example because the webserver is having to perform multiple tasks simultaneously. If the webserver were operating on a single thread, the process would take much longer as the program can only perform one task at a time. For example, if the webserver were pushing the data into the database it would not be able to listen for a new request until that process was finished.
A shell program that closely monitors its own working space, such as open files, environment variables, and current working directory would perform best using a single-threaded process. In this example the program is self-contained meaning is does not need to rely on any additional outside resources so running it in single thread makes the most sense. If the program were calling for additional resources, there may be a need to switch to multithreading as the program would not be able to pull resources and perform its function at the same time.
A program that calculates a large number of payments where each calculation is independent of other payment calculations would best perform using a single-threaded process. This example is similar to the calculator example I have provided below where there is no need for additional threads because there is only one task being performed. Each payment is made by itself where there is no relationship between additional payments so there is no need for the program to associate them.
An example that uses a single thread would be the calculator on your computer. This program takes the numerical data that the user inputs and calculates what the result will be. In this example there is no need for additional threads as there is only one function being performed at a given time even though the user may be entering numerous equations.
An example that would require a multithreaded solution would be if an individual wanted to edit videos or photographs utilizing video and photo editing software. These types of programs perform numerous tasks at once to aid in the editing process so the need for multithreading is imperative. This is especially true for video editing because as changes are being made to the video, the program is constantly updated and changing the file properties at the same time.
An example that can either be single or multithreaded would be the use of an internet browser utilizing only one tab. This example of course is specific to which type of URL the user is connected to and would only utilize a single thread if there were not numerous processes the page would have to load. On the other hand, the web browser could be multithreaded if there were numerous pages that were running “where multiple tabs can be different threads.” (GeeksforGeeks, 2021)
