The given statement, "The output unit of a pc performs the calculation and logical decisions" is false, because the output unit of a PC is responsible for displaying information to the user and presenting the results of calculations and logical decisions made by the computer's processor.

The output unit of a PC is critical in displaying data and information in a way that the user can readily see and understand. This category contains monitors, printers, speakers, and other output peripherals. Its major role is to translate processed data into a human-readable form or format, allowing users to efficiently engage with the computer system.

While the output unit can display the results of the computer's processor's calculations and logical decisions, it is important to note that the actual execution of these calculations and logical decisions take place within the central processing unit (CPU) or other components of the computer system. The output unit's role is to convey the processed information to the user in a meaningful way, whether through visual, auditory, or other sensory means.

Answer:

See explanation section

Explanation:

See the program at the end of this solution

The program can be sabotaged if the source file is altered before running the program.

Take for instance,

Someone changes

for(int i =k;i<=n;i++)

to

for(int i =3;i<=20;i++)

This implies that no matter the user input, the program will only calculate the sum of 3 to 20

It is also possible that the program is altered by an external process.

Take for instance;

n = 10

k = 1

And the sum has been calculated for the range of k = 1 to 5.

Then the program is altered by an external process.

15 (sum of 1 to 5) will be displayed instead of 55 (sum of 1 to 10)

Program written in C++

#include<iostream>

using namespace std;

int main() {

int k.n,total=0;

cin>>k;

cin>>n;

//Assume k will always be less than n

for(int i =k;i<=n;i++) {

The m:n relationship between sale and available tune can be resolved through the use of a junction table.

This table acts as a bridge between the two entities and contains foreign keys from both the sale and available tune tables. First, identify the primary keys of both the sale and available tune tables to create the junction table. These will be used as foreign keys in the junction table. The junction table will also contain any additional fields needed to record information about the relationship between the two entities, such as the date of the sale or the price paid. Overall, the use of a junction table is an effective way to resolve m:n relationships between entities.

Once the junction table is created, the m:n relationship can be resolved by inserting records into the junction table. Each record represents a sale of a specifically available tune and contains the foreign keys from the sale and available tune tables and any additional information. Queries can be used to retrieve information about the relationship between sales and available tunes. For example, a query can be used to find all available tunes that have not been sold or to find all sales of a specifically available tune.

The Address Resolution Protocol or ARP cache contains every MAC address and corresponding IP address that will be used by the host. Therefore, this refers to a true statement.

The Address Resolution Protocol or ARP is a layer 2 protocol that is used to map MAC addresses to IP addresses. On a network, all hosts are located by their IP address, but NICs do not have IP addresses, they use MAC addresses. Thus, ARP provides a critical mapping function in the Internet protocol suite to associate the IP address with a MAC address.

For example, in order to transmit data over a network, the ARP cache contains every MAC address with associated IP address of the host.
