A directional antenna or beam that used as an antenna that radiates or receives additional power from the unwanted source into certain directions that enhances performance and reduces interference.
Receiver satellite TVs commonly employ parabolic antennas.It better pulls signals in one way in which it detects a weaker or more distant signal than an omnidirectional antenna counterpart.The difference is that they do it by reducing their ability to draw signals from other directions.The coverage area is smaller yet extends farther out. This could reach up to 8 miles under optimum conditions.Learn more:

WHAT ACTIONS CAUSE SPAM ON LINKEDIN?
Answer:
LinkedIn has a very smart algorithm, and it has a very strict policy against spammers. Back in 2014, it deleted millions of accounts that were causing spam on LinkedIn.
Spam occurs:
1. When you send bulk of connect requests in a short time
2. When you send irrelevant messages to prospects
3. When you Perform overactivity
4. When you use LinkedIn automation tools
5. When you send spammy and sales-y messages
All these actions cause spam on LinkedIn, and it immediately takes action against you by restricting your account temporarily or permanently.

1.11 Additional practice: Output art1.12 zyLab training: BasicsWhile the zyLab platform can be used without training, a bit of training may help some students avoid common issues.The assignment is to get an integer from input, and output that integer squared, ending with newline. (Note: This assignment is configured to have students programming directly in the zyBook. Instructors may instead require students to upload a file). Below is a program that's been nearly completed for you.Click "Run program". The output is wrong. Sometimes a program lacking input will produce wrong output (as in this case), or no output. Remember to always pre-enter needed input.Type 2 in the input box, then click "Run program", and note the output is 4.Type 3 in the input box instead, run, and note the output is 6.When students are done developing their program, they can submit the program for automated grading.Click the "Submit mode" tabClick "Submit for grading".The first test case failed (as did all test cases, but focus on the first test case first). The highlighted arrow symbol means an ending newline was expected but is missing from your program's output.Matching output exactly, even whitespace, is often required. Change the program to output an ending newline.Click on "Develop mode", and change the output statement to output a newline: print(userNumSquared). Type 2 in the input box and run.Click on "Submit mode", click "Submit for grading", and observe that now the first test case passes and 1 point was earned.The last two test cases failed, due to a bug, yielding only 1 of 3 possible points. Fix that bug.Click on "Develop mode", change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before).Click on "Submit mode" again, and click "Submit for grading". Observe that all test cases are passed, and you've earned 3 of 3 points.userNum = int(input())userNumSquared = userNum + userNum # Bug here; fix it when instructedprint(userNumSquared, end=' ') # Output formatting issue here; fix it when instructed
Following are Python programs to the given question:
userNum = int(input())#defining a variable userNum
userNumSquared = userNum * userNum#defining a userNumSquared that calculates the square value of userNum
print(userNumSquared)#print squared value
Output:
60
3600
Program explanation:
In the above-given python code, a variable "userNum" is declared that uses an input method with the int that only takes an integer value as an input.In the next line, another variable "userNumSquared" is declared that is used to calculates the square value of "userNum". After holding the square value it uses the print method to prints its calculated value.Learn more:

What is low, high and machine level language
Answer:
A high-level language is one that is user-oriented in that it has been designed to make it straightforward for a programmer to convert an algorithm into program code. A low-level language is machine-oriented. Low-level programs are expressed in terms of the machine operations that must be performed to carry out a task. In easy words high level languages are near to human beings and far from computer and low level languages are near to computers and far from human understandings.

Answer:
#include <iostream>
int factorial(int n) {
return (n > 1) ? n*factorial(n-1) : 1;
}
int main() {
std::cout << factorial(5);
}
Explanation:
Above is an approach using recursion.
It will output 120, which is 5! = 5*4*3*2*1
#include <iostream>
using namespace std;
int main() {
// Declare the variables
int n = 19;
long int factorial = 1;
// Each time, the factorial multiplies by integers from 1 to the maximum number.
for(int i = 1; i <= n; i = i + 1) {
factorial = factorial * i;
}
// Display the factorial
cout << factorial;
return 0;
}
EXPLANATIONDeclare n and factorial as integers and long integers.
The "for loop" runs from 1 to the maximum number and increments by 1. The factorial multiplies each time by integers from 1 to n.
Print the factorial.

string ans = "";
for (int i = 0; i < workStr.length(); ++i)
ans += (i != idx ? workStr[i] : newChar);

}
Explanation:
Declares the necessary variables. Next read them and finally call a replace user defined function to solve the problem.
The program is given in C++. So, the code must be completed in C++.
The missing part of the program can be completed with the following lines of code:
string newStr(1, newChar);
workStr.replace(idx,1,newStr);
To complete the code, we first convert newChar to a string.
This is done using:
string newStr(1, newChar);
In the above code segment, a string variable newStr is initialized with the value of newChar
Next, replace the character of the string using:
workStr.replace(idx,1,newStr);
The syntax of the above instruction is:
string-variable.replace(position, number of characters to replace, replacement string)
In this case,
The string variable is workStrThe position of string to replace is idxThe number of characters is 1 (because only one character is to be replaced)The replacement string is newStrSee attachment for the complete program and a sample run

The output signal from an analogue sensor is sampled every 195 µs to convert it into a digital representation. What is the corresponding sampling rate expressed in kHz?
According to the Sampling Theorem, for this sampling rate value, what approximately could be the highest frequency present in the signal, in kHz, assuming the lowest frequency is very close to zero?
If each sample is now quantised into 512 levels, what will be the resulting bitrate in kbps?
Give your answer in scientific notation to 2 decimal places.
Hint: you need to determine the number of bits per sample that produces 512 quantisation levels.
Answer:
A sample rate is just reciprocal of the sample period. According to sampling theorem the highest frequency in single would be [tex]5.13/2=2.565 KHz.[/tex][tex]2^8=512[/tex] So you will need 8 bits to represent.[tex]8 bits \times5.128\times(10)^3[/tex]samples [tex]=41.026[/tex] bits per second.Explanation:
Sample period of 1 millisecond [tex]=1 kHz.[/tex]
Thus a sample period of [tex]0.195[/tex] milliseconds is
[tex]1/0.195=5.12820513 Hz[/tex]
To determine the sample after [tex]512[/tex] levels quantization, we need to find bits per sample that produces [tex]512[/tex] quantization levels.
Thus,
[tex]2^8=512[/tex]
So you will need 8 bits to represent.

(I tried using strVar.insert(partStr, str2) but was unsuccessful. I don’t know where I’m messing up. Thank you for your help. I’ve been trying to alter this code for a while now)
Answer:
Use the .find() function in your first string to give you an index.
Explanation:
Hi! I'm guessing you're taking COP2334 like me. A T.A. helped me figure out what I needed, so I'm passing it on.
Basically, you're given three strings and no integer to use as an index in order to insert the second line. Since you are required to have an index to use the .insert() function, this is "tear-out-my-hair" frustrating. What I failed to remember was that it is totally possible to use a function inside another function to get what you need!
You have been given is a hint as to where str2 goes, in the form of your 3rd string. If I'm right, all of the tests the system will run (mine is in Zybooks) will give a 3rd string that is inside the first string.
String 1: strVar: "FuzzyBear"
String 2: str2: "Wuzzy"
String 3: partStr "Be"
Open your statement with strVar and use the insert.() function. In the insert function, you are required to give a place to start, (your index), then what you want to insert. Your index will be the .find() function, searching in StrVar for partStr. The second part of the .insert() function is str2.
