The Test-and-Set instruction is used in hardware to achieve synchronization.It can be defined in the following way:function Test-and-Set (var target: boolean): boolean;beginTest-and-Set:= target;target := true;end;Now show how the Test-and-Set instruction can be used to protect a critical region and henceachieve mutual exclusion (do not worry about satisfying the bounded waiting condition).(8 points)repeat

(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
(Civil eng.) Modify the program written for Exercise 9 to determine the maximum load that can be placed at the end of an 8-foot I-beam, shown in Figure 2.21, so that the stress on the fixed end is 20,000lbs/in2. Use the fact that this beam’s rectangular moment of inertia is 21.4 in4 and the value of c is 3 in.
If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?
(Electrical eng.) a. Write, compile, and run a C++ program that calculates and displays the value of the current flowing through an RC circuit (see Figure 3.19). The circuit consists of a battery connected in a series to a switch, a resistor, and a capacitor. When the switch is closed, the current, i, flowing through the circuit is given by this formula: i=(EIR)et/RC Eisthevoltageofthebatteryinvolts.Risthevalueoftheresistorinohms.Cisthevalueofthecapacitorinfarads.tisthetimeinsecondsaftertheswitchisclosed.eisEulersnumber,whichis2.71828( roundedtofivedecimalplaces). Using this formula, write, compile, and run a C++ program to determine the voltage across the capacitor shown in Figure 3.19 when t is 0.31 seconds. (Note: The value of RC is referred to as the system’s time constant.) The program should prompt the user to enter appropriate values and use input statements to accept the data. In constructing the prompts, use statements such as “Enter the voltage of the battery.” Verify your program’s operation by calculating by hand the current for the following test data: Testdataset1:Voltage=20volts,R=10ohms,RC=0.044,t=0.023secondsTestdataset2:Voltage=35volts,R=10ohms,RC=0.16,t=0.067seconds b. Check the value computed by your program by hand. After verifying that your program is working correctly, use it to complete the following chart:
In the ________, memory addresses consist of a single integer.
