(b) for each of these references, identify the binary address, the tag, and the index given a direct-mapped cache with two-word blocks and a total size of 8 blocks. also list if each reference is a hit or a miss, assuming the cache is initially empty. (c) you are asked to optimize a cache design for the given references. there are three direct-mapped cache designs possible, all with a total of 8 words of data: c1 has 1-word blocks, c2 has 2-word blocks, and c3 has 4-word blocks.
Answers
In 0x03, the cache is missed because it's empty initially.
In 03 ->, the tag value is 0 as the index value is 3.
The tag and the index value can also be written in binary form.
What is a cache?A cache is a hardware or software component that stores data in order to serve future requests for that data more quickly; the data stored in a cache may be the result of an earlier computation or a copy of data stored elsewhere.
A physical address in computing is a memory address that is represented as a binary number on the address bus circuitry to allow the data bus to access a specific storage cell of main memory or a register of a memory-mapped I/O device.
Based on the information given, the references, identify the binary address, the tag, and the index given a direct-mapped cache with 16 one-word blocks has been illustrated in the attached picture.

(2) Output the total weight, by summing the array's elements.
(3) Output the average of the array's elements.
(4) Output the maximum array element.
Your program must define and call the following two functions:

Your program MUST NOT use a vector. Your program must use an array to store the weights, and loops to input and process the values.
Answers
This program will require the user to input five double values representing five people's weights. The values will be stored in an array of doubles, then total weight, average, and maximum array element will be computed and output.
Computing Total Weight, Average and Maximum Weight from an Array of People's WeightsTo solve this problem, we need to declare an array of doubles to store the five weights. We will also need to define two functions:
totalWeight to compute the total weightmaxWeight to compute the maximum weightSteps to follow:
First, we must prompt the user to enter five numbers for the weights. We can use a for loop to iterate over the array and store the values in each element. Next, we need to output the array's numbers on one line, each number followed by one space. We can use another for loop to iterate over the array and output each element, separated by a space.Now, we need to output the total weight, summing the array's elements. We can call the totalWeight function to compute and return the total weight.To output the average of the array's elements, we can divide the total weight by the number of elements in the array.Finally, we need to output the maximum array element. We can call the maxWeight function to return the maximum value in the array.Learn more about Programming: brainly.com/question/23275071

Lab12B: My dog can do tricks
For this lab we once again are going to create 2 classes, 1 called Dog and 1 called Lab12B.
Dog objects have a few attributes, but this time unlike chair objects they can also do some cool things
too. Each action is represented by a method. Therefore, for any action our Dog can do or we do to the
Dog, we are going to create a method. For example, if I want my Dog to bark, I can create a method
to do that in the Dog class and call that method in the driver Lab12B (once I have created an object.)
Dog class:
• Variables (Attributes): - make these public, like the first exercise
o int age //current age of the dog
o double weight //how much does it weight in lbs
o String/string name //what is the name of the dog
o String/string furColor //color of the dog’s fur/hair
o String/string breed //what breed is the dog
• Behaviors (Methods): - these also should be public
o bark //prints "Woof! Woof!"
o rename //take a string and change the name of the dog
o eat //take a double and add that number to weight
Keep in mind you need to have a return data type for each method and what parameters these take
to carry out their function when creating the methods.

All method attributes, such as access level, return type, name, and arguments, are defined in the method declaration.In the class, a method with the name of the method followed by parentheses must be created (). A method definition is made up of two parts: a method header and a method body. We can invoke a method by using the syntax: method name(); /calling a non-static methodA method is a class's executable element. InterSystems IRIS supports both instance and class methods.

This generation of operating systems used remote processing, time-sharing, and multiprogramming. High-level languages (such as COBOL, PASCAL PL/1, FORTRAN-II to IV, BASIC, and ALGOL-68),
Hence, A third-generation programming language is a high-level form of computer programming that is less focused on the fourth and fifth generations and is typically more machine-independent and programmer-friendly than first- and second-generation assembly languages and machine code.

which is immiscible with water? multiple choice graphicexpand image graphicexpand image graphicexpand image graphicexpand image graphicexpand image
Answers
The liquid are immiscible as the two liquid in the glass vessel present as two layer, the miscible liquid will present as single layer, therefore the liquid in the glass vessel is immiscible and two liquid have low mutual solubility.
What is Immiscibility?
Immiscibility is the property of two substances that prevents them from combining to form a homogeneous mixture. It is said that the components are "immiscible." Fluids that do mix together, on the other hand, are referred to as "miscible."
The components of an immiscible mixture will separate. The less dense component will rise to the top, while the more dense component will sink.
Water and oil are immiscible liquids. Alcohol and water, on the other hand, are completely miscible. Alcohol and water would then mix to form a homogeneous solution in any proportion.

The two variables are thought to have a linear relationship with one another. We therefore seek a linear function that, given the feature or independent variable, accurately predicts the response value(y).
What is Machine Learning - Linear Regression?Regression is the term used when attempting to determine the relationship between two variables.That relationship is used to forecast the outcome of upcoming events in statistical modeling and machine learning.In linear regression, a straight line is drawn through all of the data points using the relationship between them.You can use this line to forecast future values.Python has tools for identifying relationships between data points and for drawing a linear regression line. Instead of going through the mathematical formula, we will demonstrate how to use these techniques.The x-axis in the example below represents age, and the y-axis represents speed. We recorded the age and speed of 13 vehicles as they passed a toll booth. Let's check to see if the data we gathered could be applied to a linear regression:ExampleA scatter plot should be created first:
matplotlib.pyplot import plt
x = [5,7,8,7,2,17,2,9,4,11,12,9,6]

What is Code segment?
A code segment, also known as a text segment or simply text in the field of computing, is a section of a computer file that contains object code or an analogous segment of the program's address space that contains executable commands and directives information.
When a program is processed and executed, it is saved in a computer file, which contains object code. The code segment is one of the divisions of this object file, which when the program is stored in memory by the loader as a result of it possibly being carried out and implemented, a variety of memory segments are assigned for a specific purpose, equivalently to both segments in object code based computer files and also segments that are only required at run time during execution.
