What is WhatsApp?: WhatsApp is a freeware centralized instant messaging (IM) and voice-over-IP (VoIP) service developed by the American company Meta Platforms and available on multiple platforms worldwide. Sending and receiving text and voice messages, making audio and video conversations, and sharing pictures, documents, and users’ whereabouts are all possible.
In addition to mobile devices, desktop computers can also use the WhatsApp client application. To use the service, you need to have a cell phone number.
Whatsapp Business, a separate app aimed at small business owners, was introduced in January 2018 to facilitate two-way communication between businesses and customers using the regular Whatsapp client.
Facebook acquired WhatsApp Inc., a company based in Mountain View, California, in February 2014 for approximately US$19.3 billion. WhatsApp Inc. was the company that developed the client application.
It had more than 2 billion users all over the world by the year 2015, which established it as the most popular messaging app in the entire world.
By the year 2016, it had supplanted dial-up as the primary method of accessing the Internet in many parts of the world, including large swaths of Europe and Africa, as well as Latin America and the Indian subcontinent.
History of WhatsApp
Brian Acton and Jan Koum, both formerly of Yahoo!, created the messaging service WhatsApp.
WhatsApp wasn’t created to be a messaging app.
Koum and Acton, anticipating a multi-million dollar app industry thanks to the Apple App Store, came up with the idea for WhatsApp in January 2009. The app would display dynamic information about the contacts in your address book, such as “if you were on a call, your battery was low, or you were at the gym,” for each contact.
Koum and his Russian buddy Alex Fishman frequently met at Fishman’s house in West San Jose to talk. They understood that hiring an iPhone developer was necessary to advance the project.
To solve this problem, Fishman went to RentACoder.com, where he met Russian programmer Igor Solomennikov, whom he then introduced to Koum.
How does WhatsApp work?
WhatsApp lets you receive and send messages and calls using only an internet connection, making it free and perfect for international calling. No sign-up fees or data limits.
Although similar to other messaging programs like iMessage and Google’s Messages, WhatsApp has certain important advantages (between Android and iOS, for example).
WhatsApp is more than just a simple messaging service, despite first impressions to the contrary. Here is a quick review of WhatsApp’s primary capabilities:
Video and voice calls: WhatsApp not only supports voice conversations but also video calls, including a group feature that supports up to eight users on a single call.
Voice messaging: With the audio messaging feature, you may record and transmit voice messages to specific users or to a group.
Secure messaging: WhatsApp uses end-to-end encryption, a secure communication protocol where only the persons who are communicating may see the messages.
Photos and video sharing: You may share films, photos, and GIFs without worrying about them being pixelated or unusable due to differences in mobile operating systems or wireless providers, which can happen when sending an SMS message with an image.
Document sharing: Sharing documents is a breeze with WhatsApp; no need for email or specialised document-sharing tools when you want to transmit a PDF, spreadsheet, or presentation.
