Explanation:
The three general methods consist of unicasting, broadcasting and multicasting.
Casting implies the transfer of data from one computer (sender) to another (recipient).
Unicasting is the transfer of data from a single sender to a single recipient.
Broadcasting deals with the transfer of data from one sender to many recipients.
Multicasting defines the transfer of data from more than one sender to more than one recipients.
Describe the major issues surrounding the decisions to build and/or host your own e-commerce Web site or to outsource some aspects of site development. Include the advantages and disadvantages of each decision.
Answer:
Explanation:
The main issue with this is the time and cost of buildling and maintaining your server. You will need to know how to build a server to host your own e-commerce site but will also need to learn how to manipulate data. This includes being able to save and pull data from the server. Once you have this done then the rest is easy since that is the biggest disadvantage of hosting your own site. The biggest advantage is that you have full control over your data and do not have to pay monthly fees and hidden fees to any hosting site.
The major issue surrounding the decisions to build or hosting of your own e-commerce is that one will need a multiskilled staff.
It should be noted that when an individual wants to build an e-commerce site, they'll need a multiskilled staff like graphic artists, programmers, project managers, and web designers.
The person will also purchase the appropriate hardware and software. There are also several risks that come with building a site from scratch. The cost involved is also high as the requirements to build the site are complex.

The standard protocol for this synchronous communication is TCP/IP.
Write a program that takes a set of numbers and determines which is the smallest. Ask the user for the following information, in this order: A terminating value (real number). The user will enter this value again later, to indicate that he or she is finished providing input. A sequence of real numbers. Keep asking for numbers until the terminating value is entered.
Answer:
This solution is implemented in C++:
#include<iostream>
#include<bits/stdc++.h>
using namespace std;
int main(){
double termnum;
cout<<"Terminating number: ";
cin>>termnum;
double num;
vector<double>numbers;
cout<<"Number: ";
cin>>num;
while(num!=termnum){
numbers.push_back(num);
cout<<"Number: ";
cin>>num;
}
double smallest = numbers.at(0);
for(double x:numbers){
if(x < smallest){
smallest = x;
}
}
cout<<"The smallest is "<<smallest;
return 0;
}
Explanation:
This declares the terminating variable as double
double termnum;
The next italicized lines prompts user for terminating value
cout<<"Terminating number: ";
cin>>termnum;
This declares the user input variable as double
double num;
This declares vector of numbers as double
vector<double>numbers;
The next italicized lines prompts user for number
cout<<"Number: ";
cin>>num;
The following iteration is repeated until the terminating value equals the number supplies by the user
while(num!=termnum){
This pushes the number to a vector
numbers.push_back(num);
The italicized lines prompts user for another number
cout<<"Number: ";
cin>>num;
}
This declares and initializes variable smallest
double smallest = numbers.at(0);
The following for loop determines the smallest of the number set
for(double x:numbers){
if(x < smallest){
smallest = x;
}
}
This prints the smallest of the set
cout<<"The smallest is "<<smallest;
return 0;

What is the output of the following program
#include
int toronto (int x)
{
int w;
if (x == 0) w = 1; else w = toronto (x-1);
return (w);
}
int main (void)
{
int a = 2;
printf ("%d", toronto (a));
return (0); }
a. 0
b. 1
c. 2
d. -1
e. none of these
Answer:
The output is 1
Explanation:
Analysing the flow of program (We start from the main method)
The main begins here
int main (void) {
This line declares a as integer and also initializes it to 2
int a = 2;
This line passes 2 to the function names toronto and also prints the result of the function
printf ("%d", toronto (a));
return (0); }
The toronto function begins here.
Note that the function receives 2 as its argument and this is saved in variable x
int toronto (int x) {
This declares w as integer
int w;
If x is 0, w equals 1
if (x == 0) w = 1;
If otherwise
else
This reduces x by 1 and performs a recursion
w = toronto (x-1);
return (w);
}
Because of the structure of the if condition in the toronto function, the function will be repeated until x is 0.
And when x = 0; w = 1
This returns w (i.e. 1) back to the main function where 1 is printed as the output
return (w);

Using the Internet, search and discuss why naming conventions are important and why programmers should consistently follow them. What problems can arise in naming variables if one convention is not followed.
Answer:
Answered below
Explanation:
Some variable naming conventions include;
1) Variable should begin with either a letter or an underscore.
2) Variables having multiple words should have the first letter of every word after the first word, capitalized. This is the camelCase style.
3) variables should not be named after any of the inbuilt keywords except on special operations to override the original function of such keyword.
4) variable names are case-sensitive.
The importance of following these conventions is to maintain readability and consistency of code. Failure to follow these conventions may lead to chaotic codes, bugs and inefficient performance.

0 None of the above
PLEASE HELPPPPPP
Answer: Breaking down tasks into smaller, manageable parts
Explanation:
The word decomposition means to break down so Problem decomposition means to break down the problem being faces into smaller parts with the reason being to be able to manage it better.
Some problems are simply too large to handle singularly because of the amount of resources that would have to be devoted. It would be better to break them down into smaller tasks that can then be be confronted one at a time with enough resources to solve them each.
An array similar to a phone book has 1000 names arranged as names [0], names[1]....names[999]. Nancy wants to search a name X in this array. Which of the following preconditions must she ensure to perform a binary search?
The list has a large number of names.
The name X is present in the list.
In addition to the two statements above, which of the following is correct?
a. There should be no duplicates in the list.
b. The names in the list should be alphabetical order.
c. The name X should occur near the middle of the list.
Answer:
Preconditions that she must ensure to perform a binary search are:
The list has a large number of names.
The name X is present in the list.
c. The name X should occur near the middle of the list.
Explanation:
Nancy's binary search for a name X should begin by comparing an element in the middle of the array or list with the name X (target value). If this name X's value matches the value of an element in the list, Nancy must return its position in the array. If the name X's value is less than the element's value, Nancy will continue the search in the lower half of the array. Usually, the name X should occur near the middle of the list or array.
