WhatsApp Messenger is a freeware, cross-platform and end-to-end encrypted instant messaging application for smartphones.

It uses the Internet to make voice calls, one to one video calls; send text messages, images, GIF, videos, documents, user location, audio files, phone contacts and voice notes to other users using standard cellular mobile numbers.

It also incorporates a feature called Status, which allows users to upload photos and videos to a 24-hours-lifetime feed that, by default, are visible to all contacts; similar to Snapchat, Facebook and Instagram Stories.

Snapchat is an image messaging and multimedia mobile application created by Evan Spiegel, Bobby Murphy, and Reggie Brown, former students at Stanford University, and developed by Snap Inc., originally Snapchat Inc. One of the principal concepts of Snapchat is that pictures and messages are only available for a short time before they become inaccessible.

The prototype for Snapchat was started by Brown and Spiegel as a project for one of Spiegel's classes at Stanford, where Spiegel was a product design major.

Beginning as "Picaboo", the idea was to create a selfie app (application) which allowed users to share images that were explicitly short-lived and self-deleting.

The temporary nature of the pictures would therefore encourage frivolity and emphasize a more natural flow of interaction.

When, in April 2011, Spiegel floated the product idea in front of his class as a final project, the classmates focused on the impermanent aspect of the potential product, and balked at the thought of temporary photos.

Murphy was eventually brought into the project to write the source code for the application, and Picaboo first launched as an iOS-only app in July 2011 from Evan Spiegel's living room (who was still staying at home with his father when not away at school).

The application was relaunched two months later under the name Snapchat.

Instagram is a mobile photo-sharing application and service that allows users to share pictures and videos either publicly or privately on the service, as well as through a variety of other social networking platforms, such as Facebook, Twitter, Tumblr, and Flickr.

Originally, a distinctive feature was its confining of photos to a square, similar to Kodak Instamatic and Polaroid SX-70 images, in contrast to the 4:3 aspect ratio typically used by mobile-device cameras.

In August 2015, version 7.5 was released for mobile devices, allowing users to upload media captured in any aspect ratio, but not at full size.

Users can also apply various digital filters to their images.

In June 2013, Instagram added support for videos, allowing prerecorded square standard definition resolution clips of up to 15 seconds to be shared; later updates introduced support for widescreen resolutions at 360p and longer recording times for either pre-recorded (up to one minute per video, or up to 10 minutes with a multi-video post) or disappearing live videos (up to one hour).

Twitter is an online news and social networking service where users post and interact with messages, "tweets," restricted to 140 characters.

Registered users can post tweets, but those who are unregistered can only read them.

Users access Twitter through its website interface, SMS or a mobile device app.

Twitter Inc. is based in San Francisco, California, United States, and has more than 25 offices around the world.

A social network is a social structure made up of a set of social actors (such as individuals or organizations), sets of dyadic ties, and other social interactions between actors.

The social network perspective provides a set of methods for analyzing the structure of whole social entities as well as a variety of theories explaining the patterns observed in these structures.

The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine network dynamics.
