WhatsApp is a chat application for next-generation mobile phones, also known as smartphones. It is used to send text and multimedia messages between its users.
Its operation is similar to that of the most common instant messaging programs for computers, although it is focused on and adapted for mobile devices. There is a desktop version of WhatsApp Web for computers, so WhatsApp also works on iPad and most tablets.
Each user is identified with his mobile phone number. It is enough to know someone’s number to have it in the WhatsApp contact list… or WhatsApp, which is also correct. To converse, both the sender and the recipient must have this application installed on their digital devices.
The messages are sent through the network to the destination phone. To use WhatsApp or WhatsApp Web, you have to contract a mobile line, and it is convenient to consult the telephone offers and smartphone rates.
WhatsApp on My Mobile and WhatsApp Web on My PC
Not all mobile phones can use this application. The first requirement is that it be a smartphone and, consequently, have an operating system.
Among mobile devices, some do not support this App, though fewer and fewer do. On the WhatsApp website, you can download the application, which is pre-installed on some models. The download is free. The hoax “WhatsApp will be paid” has resurfaced many times across digital media and social networks. At the moment, it is free, including the WhatsApp Business application.
Even to use WhatsApp web on a computer, the associated mobile phone must have WhatsApp and an active account, since the web version is just a synchronized extension of the App. If the mobile application is turned off, deactivated, or is without coverage, WhatsApp web will not work either.
What is WhatsApp Used for?
The possibilities of WhatsApp vary depending on the phone or device we have. There are models that accept a basic version and others more advanced. There are versions for Android, iPhone, Mac, Windows Phone, and Windows desktop (version 8 or higher, 32-bit or 64-bit).
The application, in addition to text chat, allows sending photos, audio, and videos. It has direct access to conventional calls, which are charged by the contracted telephone operator, and WhatsApp calls, or even video calls, which are transmitted over the Internet and can either be free if we are connected to Wi-Fi, or consume data.
You can customize the application, use emoticons, or block users, among other things. In general, setup is straightforward. It is also possible to share our location with the user we connect with.
How is WhatsApp Used? Is it safe?
One of the keys to this application’s success is its accessibility. It has a simple operation, and learning is very easy. Everyone can start sending and receiving WhatsApp immediately. You choose what you want to share, write (or not) a message, and press the send button. To receive, you open the app and select the conversation.
The other strong point is the security that protects conversations through its end-to-end encryption.
The Californian company Facebook bought WhatsApp in 2014 but has not integrated it into its social network, which, at the moment, continues to use Messenger as a private messaging system between its users. Since then, security has been strengthened, including the ability for chat participants to confirm the encryption code.
According to WhatsApp, no one can decrypt the messages, not even them. As long as the contrary is not proven, of course. Is it a matter of faith?
