Answer:
1200 Hz
Explanation:
Given that the signal encodes 4-bit words, then
log2M = 4,
Again, we're told that the system operates at 9600 bps, so
C = 9600
If we bring back our earlier relation, we have
9600 = 2B * 4
9600 = 8B
B = 9600 / 8
B = 1200 Hz
Therefore, we can conclude that the minimum required bandwidth of the channel is 1200 Hz
The minimum required bandwidth of the channel is 1200 Hz
In a signal processing system, bandwidth(measured in Hertz) refers to the variation between a higher frequency and a lower frequency in a continuous range.
It can be calculated by using the formula:
[tex]\mathbf{B_ a = \dfrac{f_s}{2} }[/tex]
where;
The sampling rate [tex]\mathbf{f_s = \dfrac{R}{n}}[/tex]and;
The operation rate of the digital signaling system R = 9600 bpsThe number of bits (n) = 4∴
The sampling rate is:
[tex]\mathbf{f_s = \dfrac{9600 \ bps}{4 \ bits}}[/tex]
= 2400 Hz
The minimum required bandwith [tex]\mathbf{B_ a = \dfrac{f_s}{2} }[/tex] is:
[tex]\mathbf{B_a = \dfrac{2400 \ Hz}{2}}[/tex]
= 1200 Hz

With what speed will a clock have to be moving in order to run at a rate that is one-half the rate of a clock at rest
Answer:
Speed = 0.866c
Where c is speed of light
Explanation:
We want to find the speed at which it run at a rate that is one-half the rate of a clock at rest.
Thus, we will use time dilation equation to solve it.
Thus;
t_o/√[1 - (v²/c²)] = 2t_o
Where:
t_o is time at rest
v is the speed at which it runs
c is the speed of light.
t_o will cancel out to give;
1/√[1 - (v²/c²)] = 2
Rearranging, we have;
√[1 - (v²/c²)] = ½
Let's make v the subject of the formula;
Let's square both sides to get;
1 - (v²/c²) = ½²
1 - (v²/c²) = ¼
Rearrange to get;
1 - ¼ = v²/c²
¾ = v²/c²
Take square root of both sides to get;
v/c = √¾
v = c × 0.866
v = 0.866c

Fill in this function that takes three parameters, two Strings and an int. 4- // Write some test function calls here! The Strings are the message that should be printed. You should alternate printMessage("Hi", "Karel", 5); between the Strings after each line. The int represents the total number of lines that should be printed. public void printMessage(String lineOne, String lineTwo, in For example, if you were to call 19.
printMessage("Hi", "Karel", 5);
// Start here! 12 the function should produce the following output:
Hi
Karel
Hi
Kare
Answer:
The function in Java is as follows:
public static void printMessage(String lineOne, String lineTwo, int lines){
for(int i = 1;i<=lines;i++){
if(i%2 == 1){
System.out.println(lineOne);
}
else{
System.out.println(lineTwo);

Explanation:
This defines the function
public static void printMessage(String lineOne, String lineTwo, int lines){
This iterates through the number of lines
for(int i = 1;i<=lines;i++){
String lineOne is printed on odd lines i.e. 1,3,5....
if(i%2 == 1){
System.out.println(lineOne);
}
String lineTwo is printed on even lines i.e. 2,4,6....
else{
System.out.println(lineTwo);

An amount of money P is invested in an account where interest is compounded at the end of the period. The future worth F yielded at an interest rate i after n periods may be determined from the following formula:
F=P(1+i)n.F=P(1+i)n.
Write a program that will calculate the future worth of an investment for each year from 1 through n. The input to the function should include the initial investment P, the interest rate i (as a decimal), and the number of years n for which the future worth is to be calculated. The output should consist of a table with headings and columns for n and F. Run the program for P = $100,000, i=.05, n=10 years F=P(1+i)nF=P(1+i)n
Modify the problem by using the following general formula for compounding interests: F=P(1+i/m)^mn where, m is the number of interest payments per year. Solve the problem for m=1 (annual) and m=12 (monthly).
Answer:
def future_worth(p,i,n):
print("n \t F")

Explanation:
The "future_worth" function of the python program accepts three arguments namely the P (amount invested), i (the interest rate), and n (the number of years). The program runs a loop to print the rate of increase of the amount invested in n number of years.
How we ingest streaming data into Hadoop Cluster?
Hadoop could be described as an open source program to handle big data. By utilizing the MapReduce model, Hadoop distributes data across it's nodes which are a network of connected computers. This data is shared across the systems and thus enables it to handle and process a very large amount dataset at the same time. These collection of networked nodes is called the HADOOP CLUSTER.
Hadoop leverages the power and capabilities of it's distributed file system (HDFS) which can handle the reading and writing of large files from log files, databases, raw files and other forms of streaming data for processing using ingestion tools such as the apache Flume, striim and so on. The HDFS ensures the ingested data are divided into smaller subunits and distributed across systems in the cluster.

Write a pseudocode statement that declares the variable total so it can hold integers. Initialize the variable with the value 0
Answer:
Declare total = 0
Explanation:
Given
Variable name: total
Variable type: integer
Variable value: 0
Required
Write a pseudocode statement
Because total is meant to hold integer values, it can be initialized as:
total = 0
Using total = 0.0 means that total is meant to hold floating values. So, we make use of
total = 0
However, this variable must be declared before being initialized.
So, we make use of the following statement to declare the variable:
Declare total
"Declare total" and "total = 0" gives:
Declare total = 0
Col 1 Col2 Col 3
Row 1 23.1 13.58 14
Row 2 56.783 46.29 45.71
Write a program that accomplishes the following objectives:
1. reads in the number of rows, then the number of columns,
2. using nested FOR loops, reads in the column data for each row,
3. adds up the data for each row and derives an average for each row,
4 also adds up all the data in the table and derives an overall average.
Hints
1. Look at slides 3 and 4 of CS1336_Lect5e_nested_loops.pptx and Pr5-14.cpp for samples of nested FOR loops, especially line 38 in slide 4 for a calculation of average per student. That is very much like a row average.
2 Have two running total variables, for example rowsum and totalsum. Initialize totalsum to 0 in the beginning of the program Initialize rowsum to 0 before the inner loop (see line 29 in slide 4). Keep running totals for both of these inside the inner loop (see line 36 in slide 4). Average the rowSum after each iteration of the inner loop (see line 38 in slide 4). Average the totalsum after the outside loop ends
When the input is as shown in Figure 1. your program should produce the output as shown in Figure 2.
Figure 1: (sample input) 23 23.1 13.58 14 56.783 46.29 45.71
Figure 2 (sample output) Lverage of data in row #1 is 16.89 Average of data in row #2 is 49.59 Average of all data is 33.24
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);

Which daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed
Answer:
Swap daemon
Explanation:
Swap daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed. The main function of the swap daemon is to monitor processes running on a computer to determine whether or not it requires to be swapped.
The physical memory of a computer system is known as random access memory (RAM).
A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer.Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS),machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).
Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.
There are two (2) main types of random access memory (RAM) and these are;
1. Static Random Access Memory (SRAM).
2. Dynamic Random Access Memory (DRAM).
java Two smallest numbers Write a program that reads a list of integers, and outputs the two smallest integers in the list, in ascending order. The input begins with an integer indicating the number of integers that follow. You can assume that the list will have at least 2 integers and fewer than 20 integers. Ex: If the input is: 5 10 5 3 21 2 the output is: 2 and 3 To achieve the above, first read the integers into an array. Hint: Make sure to initialize the second smallest and smallest integers properly.
Answer:
The code to this question can be defined as follows:
import java.util.*;//import package for user input
public class Main //defining a class
{
public static void main(String[] args)//defining main method
{
int m1,m2,num,t,i;//defining integer variable
Scanner incx = new Scanner(System.in);//creating Scanner class object
m1 = incx.nextInt();//input value
m2 = incx.nextInt();//input value
if (m1 > m2)//use if block to check m1 greater than m2
{//swapping value
t = m1;//holding m1 value in t
m1 = m2;//defining m1 that take m2
m2 = t;//holding m2 value
}
for (i = 2; i < 6; i++)//defining for loop
{
num = incx.nextInt();//input value
if (num < m1) //defining if block to smallest value
{
m2 = m1;//holding m2 value in m1
m1 = num;//holding num value in m1
}
else if (num < m2)//defining if block to smallest value
{
m2 = num;//holding num value in m2
}
}
System.out.println(m1 + " " + m2);//print two smallest values
}
}
Output:
5
10
5
3
21
2
2 3
Explanation:
In the above code, five integer variable "m1, m2, num, t, and i" is declared, in which it creates the scanner class object for inputs the value and use m1 and m2 use to the input value.
In the next step, if a block is used to swap the value and pass into the for loop that use if block to find the two smallest values and hold its value into the m1 and m2 and print its value.

What is the missing line?
>>> myDeque = deque('math')
>>> myDeque
deque(['m', 'a', 'f'])
O >>> myDeque popleft
O >>> myDeque.clear()
O >>> my Deque pop
O >>> myDeque.clear()
Correct question:
What is the missing line?
>>> myDeque = deque('math')
>>> myDeque
deque(['m', 'a', 't'])
Answer:
myDeque.pop()
Explanation:
The double ended queue, deque found in the python collection module is very similar to a python list and can perform operations such as delete items, append and so on.
In the program written above, the missing line is the myDeque.pop() as the pop() method is used to delete items in the created list from the right end of the list. Hence, the 'h' at the right end is deleted and we have the output deque(['m', 'a', 't'])
myDeque.popleft () deletes items from the right.
What would the proper initialization and declaration be for an ArrayList myTemps meant to store precise temperature measurements
Answer:
Explanation:
When dealing with the Java programming language you need to first declare the variable type and then initialize that variable. Since precise temperature measurements would be in a double format (example: 98.3) then the proper way to do this would be with the following code.
ArrayList<Double> myTemps = new ArrayList<Double>();
myTemps.add(98.3);
myTemps.add(33.2);
myTemps.add(48.5);
This code declared the ArrayList as type Double and added three elements to the array
The proper initialization and declaration should be shown below.
Proper initialization and declaration:At the time of dealing with the programming language i.e. JAVA here we required to first see the type of variable after this we have to initialize it. The measurment of the temperature should be in the double format example 98.3
So, the following code should be used.
ArrayList<Double> myTemps = new ArrayList<Double>();
myTemps.add(98.3);
myTemps.add(33.2);
myTemps.add(48.5);
This code should be declared the ArrayList since type Double and added three elements to the array.
