Answer:
In C++:
#include<iostream>
using namespace std;
int main(){
int rows, cols;
cout<<"Rows: "; cin>>rows;
cout<<"Columns: "; cin>>cols;
int rowsum = 0; int totalsum = 0;
float nums[rows][cols];
for(int i = 0;i<rows;i++){
for(int j = 0;j<cols;j++){
cout<<"Row "<<i+1<<", Column "<<j+1<<": ";
cin>>nums[i][j];
rowsum+=nums[i][j]; totalsum+=nums[i][j];
}
cout<<"Average of row "<<i+1<<": "<<(rowsum*1.0/cols*1.0)<<endl;
rowsum = 0;
}
cout<<"Overall Average: "<<(totalsum*1.0)/(rows*cols*1.0);
return 0;
}
Explanation:
This line declares number of rows and number of columns as integer
int rows, cols;
This line prompts user for number of rows
cout<<"Rows: "; cin>>rows;
This line prompts user for number of columns
cout<<"Columns: "; cin>>cols;
This line initializes rowsum and totalsum to 0, respectively
int rowsum = 0; int totalsum = 0;
This line declares a 2d array
float nums[rows][cols];
The following iteration gets user input into the array
for(int i = 0;i<rows;i++){
for(int j = 0;j<cols;j++){
cout<<"Row "<<i+1<<", Column "<<j+1<<": ";
cin>>nums[i][j];
This line sum up the rows
rowsum+=nums[i][j];
This line sum up each entry
totalsum+=nums[i][j];
}
This line calculates and prints the average of each row
cout<<"Average of row "<<i+1<<": "<<(rowsum*1.0/cols*1.0)<<endl;
rowsum = 0;
}
This line calculates and prints the overall average
cout<<"Overall Average: "<<(totalsum*1.0)/(rows*cols*1.0);
What is true about the process of converting analog data into digital data?
a
To make the digital version be a more accurate representation of the analog data, the process should use fewer bits to represent each sample.
b
The digital version is a representation of the analog data but cannot include all of the details.
c
A longer interval between measured samples means more details will be captured in the conversion from analog to digital
d
The digital version contains all of the details of the analog data, as long as enough storage capacity is available.
Answer:
b. The digital version is a representation of the analog data but cannot include all of the details.
Explanation:
Analog data are continuous infinite stream of data but since the computer has finite memory, these data could only be represented on the computer by converting them to finite data. This process is called analog to digital conversion.
The following are some of the things that should be noted when doing this conversion:
1. Since the digital version is a finite representation of the analog which is infinite, it (the digital version) cannot include all of the details in the analog.
2. For the digital version to be a more accurate version of the analog data it represents, as much bit as possible should be used to represent each sample.
3. Short intervals between measured samples means more details will be captured in the conversion from analog to digital.
Analog to digital conversion of data simply involves the converting an infinite stream of data into a Finite version of the same data.
Digital data are Finite representation of the infinite data typical of analog representation. Hence, a Finite sequence, will not habor all the data or information contained in an analog record.
Therefore, the digital data representation will only be a Finite representation of the analog data and will not contain all of the details.

Which statement best describes the refraction of light
Answer:
Two wave pulses move toward each other along a rope. The two waves produced have different speeds.
Explanation:
Refraction of light is the change in the speed of light as it travels. The correct option is C.
What is refraction?The bending of light as it passes from one medium to another is caused by the difference in the speed of light in the different media.
When viewed through a medium with a different refractive index, this bending of light can cause objects to appear distorted or displaced.
The change in direction and speed of light as it passes from one medium to another, such as from air to water or from water to glass, is referred to as refraction.
This happens because the speed of light changes when it moves from one medium to another due to a change in the refractive index of the medium.
Thus, the correct option is C.

Write a python program that: - Defines a tuple of 5 integer numbers - prints the tuple - Appends a new value to the end of the tuple - prints the tuple again Please note that appending a new value to a tuple will change the tuple. However, as you learned in Unit 5, tuples are immutable i.e. do not change. Therefore, to solve this problem, you need to find a way to change a tuple.
Answer:
The program is as follows:
my_tuple = (1,2,3,4,5)
print(my_tuple)
mylist = list(my_tuple)
mylist.append(6)
my_tuple = tuple(mylist)
print(my_tuple)
Explanation:
This defines a tuple of 5 integers
my_tuple = (1,2,3,4,5)
This prints the tuple
print(my_tuple)
To add new element to the tuple; First, we convert it to list. This is done below
mylist = list(my_tuple)
Then, an item is appended to the list
mylist.append(6)
The list is then converted to tuple
my_tuple = tuple(mylist)
This prints the tuple
print(my_tuple)

True or False: One benefit of virtualization is that it allows for better use of already existing hardware that may not be seeing full utilization.
Answer:
True.
Explanation:
Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.
Generally, to use the virtualization technology on a computer, it must be enabled in the BIOS/UEFI).
Additionally, VMware tools can be installed on host computers to check which processes are having high CPU usage by using vimtop, as well as checking if vCenter Server is swapping.
Hence, one benefit of virtualization is that it allows for better use of already existing hardware that may not be seeing full utilization. Hardware components such as storage devices, central processing unit (CPU), random access memory (RAM), host computers are extensively put into use.

1. When the Cisco 2950 switch is first turned on, it behaves like a hub. Why is this so, and what must happen before the switch can send unicast traffic to a specific port
Answer:
The switch sends broadcast traffic to all ports like a hub to get the number of ports used and build its MAC address table.
Explanation:
A network switch is a device used in a LAN to connect all available workstations. Unlike a network hub, it is able to send frames from a host or workstation to another using its MAC address table.
An example of a switch is the Cisco 2950 switch. When it is first turned on, it acts as a hub, broadcasting traffic to all its ports. This process is used to create a MAC address table to get the IP address of workstations and the ports they relate to, enabling it to send unicast traffic to a specific port.
