What was the name of the switches used in second generation computers.
Answer: search on web it’s faster than brainly
Explanation:
Consider two packet switches directly connected by a link of 5000 km,
propagation speed 2.5 X10^8 m/s and transmission rate 1 Mbps. How long does it take to move
a packet of length 1,000 bytes from one packet switch to the other packet switch? Generally,
how long does it take to move a packet of length L over a link of distance d, propagation speed
s, and transmission rate R bps?
The time that is required for the packet to move over the the distance d at the speed s is 0.028 seconds.
The speed that It would take to move it in transmission is given as 0.008 seconds.
How to solve for the required timeThe details that we would have to solve the problem that we have here are given below
The distance = 5000 km, we convert to meters = 5000 * 1000
The speed of the propagation is given as (s) 2.5 x 108 m/s
The propagation delay is given as d / s
= 5000000 / 2.5 x 10^8
= 0.02 this is the value of the propagation
Next we have to find the length of the packet. L = 1000 bytes
this is equal to 8000 bits
The transmission rate is 1 Mbps = 1000000 bits
The transmission delay would be = L/R
= 8000 / 1000000
= 8 / 1000
= 0.008 seconds in transmission
The total required time that is to be gotten would be
Propagation + transmission
= 0.02 + 0.008
= 0.028

a. node.appendChild(new)
b. node.replaceChild(new, old)
c. node.insertBefore(new, child)
d. node.insert(new, old)
Option c is correct. Node.insertBefore(new, child) is the method that includes or embeds a new node directly ahead of a child node.
The Node interface's insertBefore() method places a node as a child of a given parent node ahead of a reference node.
InsertBefore() transfers the specified node to the new place if it already exists in the document. (That is, before adding it to the given new parent, it will automatically remove it from its current parent.)
As a result, a node cannot be present in two places in the document at once. The full contents of the DocumentFragment are moved into the child list of the chosen parent node if the given child is a DocumentFragment. the node that newNode is added before. In the event that this is null, newNode is appended to the end of the node's child nodes.

Explanation:
Keep in mind, you could have also chosen to do:
print("z\nu\np\nk\nf\na\n")
but it seems the character arithmetic is what is asked for...
In this lab, you complete a partially written C++ program that includes a function that returns a value. The program is a simple calculator that prompts the user for two numbers and an operator ( +, -, *, or / ). The two numbers and the operator are passed to the function where the appropriate arithmetic operation is performed. The result is then returned to the main() function where the arithmetic operation and result are displayed. For example, if the user enters 3, 4, and *, the following is displayed: 3 * 4 = 12
The source code file provided for this lab includes the necessary variable declarations and input and output statements. Comments are included in the file to help you write the remainder of the program.
Instructions
1. Write the C++ statements as indicated by the comments.
2. Execute the program by clicking the Run button at the bottom of the screen.
The output works but I get 5 errors. I get a declared performOperation() error, and then I'm getting a Division, Multiplication, Addition and Subtraction error.
Code:
// Calculator.cpp - This program performs arithmetic, ( +. -, *. / ) on two numbers.
// Input: Interactive
// Output: Result of arithmetic operation
#include
#include
using namespace std;
// Write performOperation() function declaration here
int performOperation(double numberOne, double numberTwo, string op);
int main()
{
double numberOne, numberTwo;
string operation;
double result;
cout << "Enter the first number: ";
cin >> numberOne;
cout << "Enter the second number: ";
cin >> numberTwo;
cout << "Enter an operator (+.-.*,/): ";
cin >> operation;
// Call performOperation method here
result = performOperation(numberOne,numberTwo,operation);
cout << numberOne;
cout << " " << operation << " ";
cout << numberTwo;
cout << " = ";
cout << result << endl;
return 0;
} // End of main() function
// Write performOperation function here
int performOperation(double numberOne, double numberTwo,std::string(op)){
double result;
if (op == "+")
result = numberOne + numberTwo;
else if (op == "-")
result = numberOne - numberTwo;
else if (op == "*")
result = numberOne*numberTwo;
else if (op == "/")
result = numberOne/numberTwo;
else
cout<<"Wrong input. Please try again.";
return result;
}
Using the knowledge in computational language in C++ it is possible to write a code that is a simple calculator that prompts the user for two numbers and an operator. The two numbers and the operator are passed to the function where the appropriate arithmetic operation is performed.
Writting the code:#include <iostream>
#include <string>
using namespace std;
double performOperation(double num1, double num2,
string opt);
int main()
{
double numberOne, numberTwo;
string operation;

cout << "Enter the second number: ";
cin >> numberTwo;
cout << "Enter an operator (+.-.*,/): ";
cin >> operation;
result = performOperation(numberOne, numberTwo,
operation);
cout << numberOne;
cout << " " << operation << " ";
cout << numberTwo;
cout << " = ";
cout << result << endl;
return 0;
}
double performOperation(double num1, double num2,
string opt)

double res = 0.0;

Explanation:
What you have is a dictionary object. We use { } to represent a dictionary. A dictionary consists of keys and values related to the keys. For example, you can have a dictionary which contains names of students and their GPAs
This is declared as
student_grades = {"Amy": 4.3, "Zach":4.0", "Bill": 3.2}
The names are referred to as keys and the GPA as values
You can also have both key and value as integers. Fir example you could store the cubes of numbers from 1 to 5 in a dictionary
cubes = {1: 1, 2:8, 3: 27, 4: 64, 5:125}
If you wanted to add the cube for 6 then you would use cubes[6] = 216 This creates a new entry in the dictionary 6:216 so that the dictionary is now
cubes = {1: 1, 2:8, 3: 27, 4: 64, 5:125, 6:216}
In this short program here is what is happening
j = 3 # variable j created and value set to 3
z = { } # this creates an empty dictionary named z
z[2] = 1 #adds an entry with key = 2 and value = 1; z = {2 : 1}
z[7} = 3 #key 7 and value 2 added => z = {2 : 1, 7 : 3}
z[5] = 2 #key 5, value 2 => z = {2: 1, 7 : 3, 5 : 2}
So now there are 3 entries in the dictionary i.e. 3 pairs of key-values
When you iterate through the dictionary as in
for l in z:
- you are actually iterating over the keys so l = 2, 7 and 5 on each iteration
So you are accumulating the key values
Here is what happens
First execution of loop => j = 3 , l = 2 (first key =2), j = 3 + 2 = 5
Second time: l = 7 (second key value) , j = 5 + 7 = 12
Third time: l = 5, j = 12 + 5 = 17
There is a lot more to dictionaries and sometimes it can get complicated. Suggest you search the internet for the same
Putting print() statements also helps you visualize what is happening. Code is provided in the answer section to help you

Explanation:
/* This program uses the string.h header file
The strncat() function in this file concatenates two strings. It takes three arguments, dest and source strings and number of characters to concatenate
*/
#include <stdio.h>

int main() {
char s1[10] = "Happy";
char s2[10] = " Birthday";
char s3[10]="";
strncat(s3, s1, 5); //concatenate 5 characters of s1 to end of s3 and
//store result in s3; s = "Happy"
strncat(s3, s2, 10); //concatenate s2 with current contents of s3
//s3 becomes "Happy Birthday
printf("%s", s3);
