Consider a logical address space of 64 pages of 1,024 words each, mapped onto a physical memory of 32 frames. Show your work. You can either type the solution or write

Answers

Answer 1

Answer:

Logical address = 16 bits

Physical address = 15 bits

Explanation:

Logical space, number of pages = 64 = 2^6

Word size per page = 1024 = 2^10

Size of logical address :

Number of pages * words per page

2^6 * 2^10 = 2^(6+10) = 2^16 = 16 bits

For the physical address :

Number of frames = 32 = 2^5 frames

Word size = 1024 = 2^10

Number of frames * word size

2^5 * 2^10 = 2^(10+5) = 15 bits

Code a complete Java program to load and process a 1-dimensional array.

Create clear comments as you code to tell me what you are doing.
Import the Java libraries that you will need.
Create a single dimensional array that will hold 15 wages.
In the main, load an array with all of the records from a .txt file named Salary txt. The file has 15 records in it.
Sort the array in ascending order.
Write a method named increaseWages(). This method will add $500 to each of the 15 wages. In other words, you are giving each person a raise of $500.
Pass the array to the method from the main().
Increase the wage amounts in the array (as described above), in the method. In other words, in the end the array should hold the NEW, higher wages.
Output each new wage (use the console for this)
Calculate a total of the new wages in the method
Output the total of the new wages in the method (use a dialog box for this)
Return the array with the new wages to the main().

Counting the character occurrences in a file
For this task you are asked to write a program that will open a file called “story.txt”
and count the number of occurrences of each letter from the alphabet in this file.
At the end your program will output the following report:
Number of occurrences for the alphabets:
a was used – times.
b was used – times.
c was used – times…. …and so, on
Assume the file contains only lower-case letters and for simplicity just a single
paragraph. Your program should keep a counter associated with each letter of the
alphabet (26 counters) [Hint: Use array]
Your program should also print a histogram of characters count by adding
a new function print Histogram (int counters []). This function receives the
counters from the previous task and instead of printing the number of times each
character was used, prints a histogram of the counters. An example histogram for
three letters is shown below) [Hint: Use the extended asci character 254]

Write a function process_spec that takes a dictionary (cmap), a list (spec) and a Boolean variable (Button A) as arguments and returns False: if the spec has a color that is not defined in the cmap or if Button A was pressed to stop the animation Otherwise return True

Answers

Answer:

Explanation:

The following code is written in Python. The function takes in the three arguments and first goes through an if statement to check if Button A was pressed, if it was it returns False otherwise passes. Then it creates a for loop to cycle through the list spec and checks to see if each value is in the dictionary cmap. If any value is not in the dictionary then it returns False, otherwise, it returns True for the entire function.

def process_spec(cmap, spec, buttonA):

   if buttonA == True:

       return False

   

   for color in spec:

       if color not in cmap:

           return False

1. Worldwide Web: In computing, WWW simply means World Wide Web. The world wide web was invented by Sir Tim Berners-Lee in 1990 while working with the European Council for Nuclear Research (CERN); Web 2.0 evolved in 1999. Basically, WWW refers to a collection of web pages that are located on a huge network of interconnected computers (the Internet). Also, users from all over the world can access the world wide web by using an internet connection and a web browser such as Chrome, Firefox, Safari, Opera, etc.

In a nutshell, the World Wide Web is an information system that is generally made up of users and resources (documents) that are connected via hypertext links.

2.E-mail: An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send and receive texts and multimedia messages over the internet.

It is considered to be one of the most widely used communication channel or medium is an e-mail (electronic mail).

3. Powerline networking: this is a wired networking technology that typically involves the use of existing electrical cables in a building to connect and transmit data on network devices through powerline network adapters.

4. Cable: this include network cables such as CAT-5, CAT-6 and fiber optic cables used for connecting and transmitting signals between two or more network devices.

What does getfenv() do?

Answers

Answer: getfenv() is a type of function. Particually a envirotment function. for a lua coding.

Explanation: What this does it goes thourgh  line of code in a particular order.

This means. getfenv is used to get the current environment of a function. It returns a table of all the things that function has access to. You can also set the environment of a function to another environment.

Forgot to include examples of where this could be used. Although not very common uses, there are some. In the past Script Builders used getfenv to get the environment of a script, and setfenv to set the environment of a created script’s environment to a fake environment, so they couldn’t affect the real one. They could also inject custom global functions.

Not entirely sure if this uses getfenv or setfenv, but the use in Crazyman32’s AeroGameFramework is making the environment of each module have access to other modules without having to require them, and having access to remotes without having to directly reference them.

Is the proportion of the female population age 60 or older in country A greater than the proportion of the female proportion age 6 or older in country B Read this excerpt adapted from The Rocket: The Story of the Stephensons, Father and Son by H. C. Knight. It was a critical moment, but [Stephenson] had no fears of the result. Robert often came to Liverpool to consult with his father, and long and interesting discussions took place between father and son concerning the best mode of increasing and perfecting the powers of the mechanism. One thing wanted was greater speed; and this could only be gained by increasing the quantity and the quality of the steam. For this effect a greater heating surface was necessary, and mechanics had long been experimenting to find the best and most economical boiler for high-pressure engines. Young James, son of that Mr. James who, when the new Liverpool and Manchester route was talked of, was the first to discover and acknowledge George Stephenson's genius, made the model of an improved boiler, which he showed to the Stephensons. He introduces himself to our notice now with a patented model of an improved boiler in his hand, which Stephenson thinks it may be worth his while to make trial of. "Try it," exclaimed the young inventor"try it, and there will be no limit to your speed. Think of thirty miles an hour!" The improved boiler was what is called a multi-tubular boiler. An iron boiler is cast, six feet long, and three feet and a third in diameter. It is to be filled half full of water. Through this lower half there run 25 copper tubes, each about three inches in diameter, open at one end to the fire, through which the heat passes to the chimney at the other end. You see this would present a great deal of heating surface to the water, causing it to boil and steam off with great rapidity. The invention was not a sudden growth, as no inventions are. Fire-tubes serving this use started in several fertile minds about the same time, and several persons claimed the honor of the invention; but it was Stephenson's practical mind which put it into good working order and made it available. For he told Robert to try it in his new locomotive.What is explained in this excerpt that is not explained in "The Steam Engine"? A.
