What is Symmetric and Asymmetric DSL?
Answer:
Symmetric DSL is called “symmetrical”
Explanation:
rocessor A has a CPI 1.2 and a clock rate of 1 GHz. Processor B has a CPI of 2.0 and a clock rate of 2 GHz. Processor C has a dock rate of 2.5 GHz (400 ps/cycle) and a CPI of 2.6. All three processors implement the same instruction set. Determine the time per instruction for each processor and write it in the correct spot. Which processor is faster? How many times faster is it than the slowest processor?
Explanation & answer:
To understand technical questions, it is necessary to understand all technical terms used.
Here,
CPI = cycles per instruction
clock rate = number of cycles the processor generates.
1 GHz = 1,000,000,000 cycles per second
= 1 nanosecond / cycle.
Processor A
CPI = 1.2 cycles per instruction
Frequency 1 GHz.
time per instruction,
Ta = (1.2 cycles/instr. )/ 1 GHz
= (1.2 cycles / instr. ) / (1 cycle / nanosecond)
= 1.2 nanoseconds / instruction
Processor B
CPI = 2.0 cycles per instruction
Frequency 2 GHz.
time per instruction,
Tb = (2.0 cycles/instr. )/ 2 GHz
= (2 cycles / instr. ) / (2 cycles / nanosecond)
= 1.0 nanosecond / instruction
Processor C
CPI = 2.6 cycles per instruction
Frequency 2.5 GHz.
time per instruction,
Tc = (2.6 cycles/instr. )/ 2.5 GHz
= (2.6 cycles / instr. ) / (2.5 cycles / nanosecond)
= 1.1 nanoseconds / instruction
The fastest is Tb = 1.0 nanosecond/instruction
The slowest is Ta = 1.2 nanoseconds/instruction
The ratio fastest/slowest = 1.2/1.0 = 1.2 times as fast
Note: cycles per instructions (CPI) are always in whole number cycles. CPI for different instructions may vary according to complexity of instruction. Decimal CPI usually indicates the value is a weighted mean of the set of instructions.

find the inverse function of f(x)= 1+squareroot of 1+2x
Answer:
Therefore the inverse function of [tex]f(x)=1+\sqrt{1+2x}[/tex] is [tex]\frac{x^2-2x}{2}[/tex]
Explanation:
We need to find the inverse of function [tex]f(x)=1+\sqrt{1+2x}[/tex]
Function Inverse definition :
[tex]\mathrm{If\:a\:function\:f\left(x\right)\:is\:mapping\:x\:to\:y,\:then\:the\:inverse\:functionof\:f\left(x\right)\:maps\:y\:back\:to\:x.}[/tex]
[tex]y=1+\sqrt{1+2x}[/tex][tex]\mathrm{Interchange\:the\:variables}\:x\:\mathrm{and}\:y[/tex]
[tex]x=1+\sqrt{1+2y}[/tex]
[tex]\mathrm{Solve}\:x=1+\sqrt{1+2y}\:\mathrm{for}\:y[/tex]
[tex]\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}[/tex]
[tex]1+\sqrt{1+2y}-1=x-1[/tex]
Simplify
[tex]\sqrt{1+2y}=x-1[/tex]
[tex]\mathrm{Square\:both\:sides}[/tex]
[tex]\left(\sqrt{1+2y}\right)^2=\left(x-1\right)^2[/tex]
[tex]\mathrm{Expand\:}\left(\sqrt{1+2y}\right)^2:\quad 1+2y[/tex]
[tex]\mathrm{Expand\:}\left(x-1\right)^2:\quad x^2-2x+1[/tex]
[tex]1+2y=x^2-2x+1[/tex]
[tex]\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}[/tex]
[tex]1+2y-1=x^2-2x+1-1[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]2y=x^2-2x[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}2[/tex]
[tex]\frac{2y}{2}=\frac{x^2}{2}-\frac{2x}{2}[/tex]
[tex]\mathrm{Simplify}[/tex]
[tex]y=\frac{x^2-2x}{2}[/tex]
Therefore the inverse function of [tex]f(x)=1+\sqrt{1+2x}[/tex] is [tex]\frac{x^2-2x}{2}[/tex]
2. Design a Do-While loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.
#include <iostream>
#include <string>
main ()
{
using std::cout;
using std::cin;
std::string s;
do
{
cout<<"Type 2 numbers: ";
int a,b;
cin>>a>>b;
cout<<"Sum of your numbers equals to: "<<a+b;
cout<<"\nType \"Yes\" if you want to continue.";
cin>>s;
}while(s=="Yes");
return 0;
}
Answer:
Program :
#include <iostream> // Header file.
using namespace std;
int main () // Main function which starts the executions
{
int First_Number,Second_Number; // variable declaration.
char choice; // Variable declaration.
do // do while loop
{
cout<<"Enter two number for addition"; // user instruction
cin>>First_Number>>Second_Number; // take a input
cout<<"The adition of "<<First_Number<<" and "<<Second_Number<<" is: "<<First_Number+Second_Number; //Addition will print
cout<<"\nType \"Y\" for continue the operation again otherwise press any key"; // User message for choice.
cin>>choice; // input for choice.
}
while(choice=='Y'||choice=='y'); // condition for Do-While loop
return 0; // return statement.
}
Output:
If the user input are 4,5 and u then the output is 9If the user input are 5,6 and y and 7,8 and u then the output are 11, 15.Explanation:
The above code is in C++ language.The above program firstly renders a message to enter the two numbers.Then it performs addition operation and then the result will be printed.Then it renders a message for the user choice.If the user enters capital y or small y, then the above operation will continue again.Otherwise, the program will be terminated.A VPN: provides secure, encrypted communications using Telnet. is an Internet-based service for delivering voice communications. is an encrypted private network configured within a public network. is a proprietary networking service technology developed by individual corporations. is more expensive than a dedicated network.

Explanation:
In order to "print" the data in an object, the class should override the _____ method.
String
toString
StringValue
Value
Answer:
toString is right Answer
Explanation:
If you want to represent any object as a string, toString() method comes into existence.
The toString() method returns the string representation of the object.
If you print any object, java compiler internally invokes the toString() method on the object. So overriding the toString() method, returns the desired output, it can be the state of an object etc. depends on your implementation.
