The total time it will take to read the same 750 Kbytes off the optical disk is 653.75 ms
Considering the parameters given in the question, the total time taken to read the same drive is the addition of the average access time together with the time to transfer the data.
Mathematically;
Total Time taken = Access time (avg.) + data transfer time
where;
access time(avg.) = 185 msthe data transfer time can be estimated by using the formula:
= required quantity of data transferred/ speed of data transfer
= 750 kbytes ÷ 1600 Kbytes/s
= 0.46875 s
= 468.75 ms
∴
Total Time taken = 185 ms + 468.75 ms
= 653.75 ms

Write a C++ program that display a checkerboard pattern made of stars and blanks, as shown below. A checkerboard is eight squares by eight squares. This will be easier if you first declare two named string constants representing the two different row patterns. Be sure to include appropriate comment in your code, choose meaningful identifiers, and use indentation as do the programs.
The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program in C++ where comments are used to explain each line is as follows:
#include <iostream>
using namespace std;
int main(){
//This declares and initializes all variables
string star = "*", blank = " ", temp;
//The following iteration is repeated 8 times
for (int i = 1; i <= 8; i++) {
//The following iteration is repeated 8 times
for (int j = 1; j <= 8; j++) {
//This prints stars
if (j % 2 != 0) {
cout << star;
}
//This prints blanks
else if (j % 2 == 0) {
cout << blank;
}
}
//This swaps the stars and the blanks
temp = star;
star = blank;
blank = temp;
//This prints a new line
cout << endl;
}

False
Answer:
True
Explanation:
If you declare a variable in the initializer, it is local to the loop
In a FOR loop, if you declare a variable in the initializer, it exists only inside of the FOR loop is a true statement.
Can you declare a variable on a for loop?It is often seen that variable which acts in control of a for loop is required only for the aim of the loop and it cannot be used in another.
Conclusively, it is therefore likely to state the variable inside the initialization part of the for loop.

Given a main program that searches for the ID or the name of a student from a text file, complete the findID() and the findName() methods that return the corresponding information of a student. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains the name and the ID of a student, separated by a space.
Method findID() takes two parameters, a student's name and a Scanner object containing the text file's contents. Method findID() returns the ID associated with the student's name if the name is in the file, otherwise the method throws an Exception object with the message "Student ID not found for studentName", where studentName is the name of the student.
Method findName() takes two parameters, a student's ID and a Scanner object containing the text file's contents. Method findName() returns the name associated with the student's ID if the ID is in the file, otherwise the method throws an Exception object with the message "Student name not found for studentID", where studentID is the ID of the student.
The main program takes three inputs from a user: the name of a text file (String), a user choice of finding the ID or the name of a student (int), and the ID or the name of a student (String). If the user choice is 0, findID() is invoked with the student's name as one of the arguments. If the user choice is 1, findName() is invoked with the student's ID as one of the arguments. The main program finally outputs the result of the search or a message if an exception is caught.
Ex: If the input of the program is:
roster.txt 0 Reagan
and the contents of roster.txt are:
Reagan rebradshaw835
Ryley rbarber894
Peyton pstott885
Tyrese tmayo945
Caius ccharlton329
the output of the program is:
rebradshaw835
Ex: If the input of the program is:
roster.txt 0 Mcauley
the program outputs an exception message:
Student ID not found for Mcauley
Ex: If the input of the program is:
roster.txt 1 rebradshaw835
the output of the program is:
Reagan
Ex: If the input of the program is:
roster.txt 1 mpreston272

Explanation:
- You should call your file the same as your class (i.e., LabProgram.java)

- The find methods are very similar, they loop through the lines of the roster, splitting each line at a space and doing string comparison.

9.1 a. What is a device register? b. What is a device data register? c. What is a device status register?
(a) A device register is a register (or memory location) that is used for data transfer
to/from an input/output device. It provides a means of communication between the
processor and the input/output device. The processor can poll this register to find out
whether it has received an input or it can send an output from/to the specific device that the device register belongs to. In memory mapped I/O device registers are dedicated memory locations for each I/O device. There may be more than one device register (dedicated memory location) for one device.
(b) A device data register is a device register (a dedicated memory location in
memorymapped I/O) that holds the data that is to be input/output.
(c) A device status register is a device register (a dedicated memory location in
memorymapped I/O) that indicates the status of the input/output. It allows for the
processor to know whether or not input/output of the value in the device data register has occurred. Basically it is an important step to achieve synchronization in an asynchronous I/O system.
A ) Registered Devices means the MAC Address of a network interface on a Compatible Device in the name of the Customer registered (in a manner as ASK4 shall from time to time determine) to receive the Service and/or an Additional Service.
b) A device data register is a device register (a dedicated memory location in memorymapped I/O) that holds the data that is to be input/output. (c) A device status register is a device register (a dedicated memory location in memorymapped I/O) that indicates the status of the input/output.
(c) A device status register is a device register (a dedicated memory location in memorymapped I/O) that indicates the status of the input/output. It allows for the processor to know whether or not input/output of the value in the device data register has occurred.
What is the purpose of using status register?The status register lets an instruction take action contingent on the outcome of a previous instruction. Typically, flags in the status register are modified as effects of arithmetic and bit manipulation operations. For example, a Z bit may be set if the result of the operation is zero and cleared if it is nonzero.
