While the conceptual idea after a computer was developed in the 19th century, the first electronic computer was created in the 1940s.

<h3>How does the evolution of computers impacts the society?</h3>

Computers have transformed the way people relate to one another and their living environment, as well as how humans manage their work, their communities, and their time. Society, in turn, has affected the development of computers via the needs people have for processing data.

<h3>What are the evolution of computers?</h3>

The first modern computer was built in the 1930s and was called the Z1, which was followed by large machinery that took up whole rooms. In the '60s, computers evolved from professional use to private use, as the first personal computer was presented to the public.

You listened to a song on your computer. Did you use hardware, software, or both?

Bogdan [553]

The answer to your question is: Explain- 
The CPU, monitor, speaker or earphone, keyboard, mouse etc. that you can touch are hardware. 
The software or program such as the operating system, windows media player, ms office, paint etc that you cannot touch actually but they are shown on the monitor are called software. 

# You play the music with Windows media player or any music player that means you are using software. And the software itself is showing on the monitor(hardware) that is run by CPU, another hardware. 

Hope you got it.. Please give me brnliest.

What is the device that converts the signals to and from the wires so that the data can be sent and received by the computer?

netineya [11]

Answer:

E. Modem

Explanation:

A network comprises of two or more interconnected devices such as computers, routers, switches, smartphones, tablets, etc. These interconnected devices avail users the ability to communicate and share documents with one another over the network.

In order for a network to exist or be established, the devices must be turned (powered) on and interconnected either wirelessly or through a cable (wired) connection.

In Computer Networking, a node is the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Examples of network nodes are routers, hubs, computer, switches, smartphone, printers, modem, etc.

A modem is a networking device that converts the signals to and from the wires such as a telephone line, so that the data can be sent and received by the computer.

Basically, a modem is an abbreviation for modulator and demodulator and as such it is designed to convert signal from one network device to signals that another network device such as a computer can understand or read.

When sending a signal (data) over a network, a modem converts (modulate) digital data signal to an analogue signal and transmits it over a telephone line or other communication lines. Also, when receiving an analogue signal, a modem converts (demodulate) the signal to a digital data signal.

Write a function called printbackwards() that will work with a c++ string. the function will print any c++ string backwards. you

dangina [55]

Hi!

Well, this isn't exactly a question - but rather just a request. However, I'm going to attempt to try and describe to you how to approach this problem, instead of just writing the code for you and sending you on your way.

So, what's our general base goal here? We want to take a string into a function, and then print it out backwards. Seems simple enough!

Right away, we already have an idea how to set this code up. We need a main method which will call PrintBackwards(), which will have to take a parameter of type string.

This would look something like PrintBackwards(string baseString). Inside this method, we'd have to do something so we can see each character in this string and then store it in a new string.

I encourage you to try and tackle this on your own, but I can give you an idea. We can have a new valueless variable called reversedString, which will store our baseString but backwards.

We could try looping through the baseString for each character it possesses, and then keep adding onto our reversedString by doing something like +=. What I mean, is we'd access the very last index of baseString, and then keep appending characters into it.

So our loop would look something like for(int i = baseString.length; i > 0; i--) {}.

I haven't used C++ in awhile, so you'll have to find the specific syntax requirements. But with that loop, i represents the index of each character in baseString. It starts with the last index, and keeps going down in reverse.

Inside our loop, we could do something like reverseString += baseString.index(i); Again, I don't remember the specific syntax - so you'll have to do this on your own.

Hopefully, this helps! =)
