Answer:

Buyers can source products from anywhere in the world.

Your purchases are delivered to the location you specify.

Explanation:

E-commerce refers to the process of buying and selling goods and services through the internet or the virtual world. The economic and business transaction done through this process constitutes electronic commerce or e-commerce.

Two advantages for buyers are that the <u>buyer can source the goods and products from all over the world and also get them delivered at the location specified</u>. This allows for an easy and effortless transaction and also saves the buyer's time and energy. With things available at just a touch of an electronic screen, the buyer can get products from anywhere and get them delivered at his/ her doorstep or for that matter, anywhere he/she wished it delivered, with no extra effort from his side.

Thus, the correct answers are the third and fourth options.

There exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is

nalin [4]

Answer:

Date Date::operator++( int )

{

Date temp = *this;

Increment();

return temp;

}

Explanation:

Of options 1 through 4, only option 4 correctly implement the post increment of the ++ operator.

Interpreting each line of option for and comparing it to other options

Line 1: Date Date::operator++( int )

This declares the data type and its ++ operator

This is same for all options

Line 2: The Date type needs to be declared

In option 4, it was declared correctly as Date temp = *this; using a pointer variable *this.

Here, option 2 is removed from the list of possible options.

Comparing other options

Line 3: The member increment option needs to be declared after the declaration of the date type variable.

This is correctly declared as Increment(); in option 4

Here, option 3 is removed from the list of possible options.

Comparing other options

Line 4: The value declared variable temp needs to be returned the way it was declared (without pointer indicator)

Hence, option 4 is best appropriate

Which of the following is true of how the Internet has responded to the increasing number of devices now using the network? a) T

zalisa [80]

Answer:

Explanation:

The internet protocols are changed every year to adapt to the new devices that have been connected to the network. Back in the 1990s, most traffic used a few protocols. Pv4 routed packets, TCP turned those packets into connections, SSL (later TLS) encrypted those connections, DNS named hosts to connect to, and HTTP was often the application protocol using it all.

For many years, there were negligible changes to these core Internet protocols; HTTP added a few new headers and methods, TLS slowly went through minor revisions, TCP adapted congestion control, and DNS introduced features like DNSSEC. The protocols themselves looked about the same ‘on the wire’ for a very long time (excepting IPv6, which already gets its fair amount of attention in the network operator community.)

As a result, network operators, vendors, and policymakers that want to understand (and sometimes, control) the Internet have adopted a number of practices based upon these protocols’ wire ‘footprint’ — whether intended to debug issues, improve quality of service, or impose policy.

Now, significant changes to the core Internet protocols are underway. While they are intended to be compatible with the Internet at large (since they won’t get adoption otherwise), they might be disruptive to those who have taken liberties with undocumented aspects of protocols or made an assumption that things won’t change.

Write a script that prints the multiples of 7 between 0 and 100. Print one multiple per line and avoid printing any numbers that

Sedbober [7]

Answer:

The program to this question can be described as follows:

Program:

#include <iostream> //defining header file

using namespace std;

int main() //defining main method

{

int x; //defining integer variable

for(x=0;x<=100;x++) //defining loop to count value from 0 to 100

{

if(x%7==0) //check value is divisable by 7

{

cout<<x<<endl; //print value

}

return 0;

}

Output:

please find the attachment.

Explanation:

In the above code, an integer variable x is declared, which is used in the for loop, in this loop variable "x" starts from 0 and ends when the value of x is less than and equal to 100.

Inside the loop an, if block is used that defines a condition that is (i%7==0), it will check, that the value is divided by 7.
In this loop, a print method is used, that prints its values.
