Hepp 4. This diagram shows an example of memory configuration under dynamic partitioning after manyplacement and swapping-out operations have been carried out. Addresses go from left to right; grayareas indicate blocks occupied by processes; white blocks indicate free memory blocks. The lastprocess placed is 2-Mbyte and is marked with an X. Only one process was swapped out after that.4M「u txsuSM2M4M3Ma. If you are to add a new 10MB process in the memory, where could it possibly be added andwhy?b.

(Practice) Although the total number of bytes varies from computer to computer, memory sizes of millions and billions of bytes are common. In computer language, the letter M representsthe number 1,048,576, which is 2 raised to the 20th power, and G represents 1,073,741,824, which is 2 raised to the 30th power. Therefore, a memory size of 4 MB is really 4 times 1,048,576 (4,194,304 bytes), and a memory size of 2 GB is really 2 times 1,073,741,824 (2,147,483,648 bytes). Using this information, calculate the actual number of bytes in the following: a. A memory containing 512 MB b. A memory consisting of 512 MB words, where each word consists of 2 bytes c. A memory consisting of 512 MB words, where each word consists of 4 bytes d. A thumb drive that specifies 2 GB e. A disk that specifies 4 GB f. A disk that specifies 8 GB
(Practice) a. Using Figure 2.14 and assuming the variable name rate is assigned to the byte at memory address 159, determine the addresses corresponding to each variable declared in the following statements. Also, fill in the correct number of bytes with the initialization data included in the declaration statements. (Use letters for the characters, not the computer codes that would actually be stored.) floatrate; charch1=M,ch2=E,ch3=L,ch4=T; doubletaxes; intnum,count=0; b. Repeat Exercise 9a, but substitute the actual byte patterns that a computer using the ASCII code would use to store characters in the variables ch1, ch2, ch3, and ch4. (Hint: Use Appendix B.)
1. Consider the following incomplete C++ program: #include int main() { … } a. Write a statement that includes the header files fstream, string, and iomanip in this program. b. Write statements that declare inFile to be an ifstream variable and outFile to be an ofstream variable. c. The program will read data from the file inData.txt and write output to the file outData.txt. Write statements to open both of these files, associate inFile with inData.txt, and associate outFile with outData.txt. d. Suppose that the file inData.txt contains the following data: Giselle Robinson Accounting 5600 5 30 450 9 75 1.5 The first line contains a person's first name, last name, and the department the person works in. In the second line, the first number represents the monthly gross salary, the bonus (as a percent), and the taxes (as a percent). The third line contains the distance traveled and the traveling time. The fourth line contains the number of coffee cups sold and the cost of each coffee cup. Write statements so that after the program executes, the contents of the file outData.txt are as shown below. If necessary, declare additional variables. Your statements should be general enough so that if the content of the input file changes and the program is run again (without editing and recompiling), it outputs the appropriate results. Name: Giselle Robinson, Department: Accounting Monthly Gross Salary: $5600.00, Monthly Bonus: 5.00, Taxes: 30.000 Paycheck: $4116.00 Distance Traveled 450.00 miles, Traveling Time: 9.00 hours Average Speed: 50.00 miles per hour Number of coffee Cups Sold: 75, Cost: $1.50 per cup Sales Amount = $112.50 e. Write statements that close the input and output files. f. Write a C++ program that tests the statements in parts a through e.
