Answer: Direct competitive
Explanation:
   The direct competitive situation occur when the two and more than two business in the market offering the similar type of services and the products so it automatically increase the level of competition in the market. 
 According to the question, the internet service is one of the most efficient tool for influence the customers or consumers about their products in the market and when the services are get switched then it utilize the direct competitive in the market. 
Therefore, direct competitive is the correct option. 
 
        
             
        
        
        
Answer:
Following are the program in the C++ Programming Language.
//set header file
#include <iostream>
//set namespace
using namespace std;
//define class
class format
{
//set access modifier
 public:
//set string type variable
  string res;
//define function
  void names(string first_name, string last_name)
  {  
//set if-else if condition to check following conditions
    if(first_name.length()>0 && last_name.length()>0)
    {
      res="Name: "+last_name+", "+first_name;
    }
    else if(first_name.length()>0 and last_name.length()==0)
    {
      res="Name: "+first_name;
    }
    else if(first_name.length()==0 and last_name.length()==0)
    {
      res="";
    }
  }
//define function to print result
  void out(){
    cout<<res<<endl;
  }
};
//define main method
int main() {
//set objects of the class
  format ob,ob1,ob2;
//call functions through 1st object
  ob.names("John","Morris");
  ob.out();
//call functions through 2nd object
  ob1.names("Jhon","");
  ob1.out();
//call functions through 3rd object
  ob2.names("", "");
  ob2.out();
}
<u>Output</u>:
Name: Morris, John
Name: Jhon
Explanation:
<u>Following are the description of the program</u>:
- Define class "format" and inside the class we define two void data type function.
- Define void data type function "names()" and pass two string data type arguments in its parameter "first_name" and "last_name" then, set the if-else conditional statement to check that if the variable 'first_name' is greater than 0 and 'last_name' is also greater than 0 then, the string "Name" and the following variables added to the variable "res". Then, set else if to check that if the variable 'first_name' is greater than 0 and 'last_name' is equal to 0 then, the string "Name" and the following variable "first_name" added to the variable "res".
- Define void data type function "out()" to print the results of the variable "res".
- Finally, we define main method to pass values and call that functions.
 
        
             
        
        
        
The answer here is Blind carbon copy (bcc).
The original recipients of the letter are unable to see (blind) who else receives a copy if those parties are on the bcc list.
 
        
             
        
        
        
Answer:RISC(reduced instruction set computer) is the computer used for low level operation by simple command splited into numerous instructions in single clock only and CISC(Complex instruction set computer) is the computer that performs the operation in single instruction.
RISC architecture has hardwired control unit,data cache unit,data path ,instruction cache and main memory as components .CISC architecture persist of  control unit,micro program control memory, cache, instruction and data path and main memory. 
The differences between RISC and CISC are as follows:-
-  The instruction in RISC are less and and low complexes while CISC has several number of complex instruction.
- The calculation done by RISC are precise and quick whereas CISC has slightly slow calculation processing.
-  The execution of RISC is faster as compared to CISC.
- RISC uses hardware component for implementation of instruction because it does not persist its own memory and CISC implements instructions using its own memory unit .
