The statement that is true about network protocols is that:
Using a protocol other than TCP/IP can result in data loss.What are network protocols?A network protocol is a system of principles that governs how data is delivered between devices on the same network.
Primarily, it enables linked devices to interact with one another despite variations in internal operations, architecture, or design.
The way this is done is true the use of Transmission-control protocol/Internet protocol (TCP/IP).
TCP/IP is the primary protocol or communication language of the Internet. Therefore, using a protocol other than TCP/IP can result in data loss.

. Write programming code in C++ for school-based grading system
Explanation:
The grade must be calculated based on following pattern:
Average Mark RangeGrade91-100A181-90A271-80B161-70B251-60C141-50C233-40D21-32E10-20E2
Calculate Grade of Student in C++
To calculate grade of a student on the basis of total marks in C++ programming, you have to ask from user to enter marks obtained in 5 subjects. Now add marks of all the 5 subjects and divide it by 5 to get average mark. And based on this average mark, find grade as per the table given above:
// C++ Program to Find Grade of Student // -------codescracker.com------- #include<iostream> using namespace std; int main() { int i; float mark, sum=0, avg; cout<<"Enter Marks obtained in 5 Subjects: "; for(i=0; i<5; i++)
Kamal plans to offer new, more favorable contracts to business customers who are now receiving a discount and use wireless services. Determine whether each customer should receive a new contract as follows:
a. In cell 15, enter a formula using the AND function that tests whether the Wireless value is equal to "Y" and whether the Discount value is equal to "Y".
b. Fill the range 16:118 with the formula in cell 15.
Solution :
'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.
Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true. If one of the P or Q is not true, then outcome result will be false.
In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.
Therefore, using the AND operation of the customers as :
Customer Wireless Discount Outcome
A N N FALSE
B Y N FALSE
C N Y FALSE
D Y Y TRUE

I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?
a. hard drive is full
b. photos were taken in a different country
c. USB port is broken
d. the file structure of the 2 hard drives are not compatible
The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.
The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.
Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:
JPEGPNGJFIFAny external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.
The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false
Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:
"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer
Answer:
c. Copy the executable file to the user’s computer
Explanation:
When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.
To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.
The program will work fine without errors.
However, do not mistake the executable file for the source file. The source file ends in .cpp.

Why are data silos problematic?
Answer:
Hampers collaboration
Resource wastage
Lack of data integrity
Explanation:
Data silos comes into play When different departments of an orgainiziations independently collects data needed for its operations. The finance, HR, administrative departments and so on collects their data and keeps it to themselves. As a result there is a repetitive and needless gathering and storage of already existing data, that is the data required by one group will have to be gathered again while it currently exists with another group. This leads to inefficient resource management and wastage. This practice also leads to data integrity as data stored differently across departments becomes inconsistent and less accurate over time. Team work and collaboration is gradually eroded as each group continues to hold on to its resources which poses a problem towards organizational growth.
