What is Playstation 4
The PlayStation 4 (abbreviated as PS4) is a home video game console developed by Sony Computer Entertainment. Announced as the successor to the PlayStation 3 during a press conference on February 20, 2013, it was launched on November 15 in North America, November 29 in Europe, South America and Australia, and February 22, 2014 in Japan.

Playstation 4 Features
PS4 Apps – Like the PlayStation 3 before it, PlayStation 4 will come with a number of apps. Eleven different applications are available for download on day one, featuring everything from diverse programming to sports action.
The DualShock 4 – Not Your Routine Controller – While some people have grown accustomed to the DualShock 3 controller – especially considering it replaced the somewhat light SIXAXIS – Sony did some research into its next-generation peripheral. As a result, we’ve got the Dual Shock 4, which feels like a dream. With more comfortable triggers (no more “finger pinching,” thankfully), comfortable analog sticks and a Touch Pad that interacts with certain games, it’s perhaps the best controller that Sony’s made.
Streaming Favorites from the Past – Although the service won’t be available at launch, Sony is hard at work with its Gaikai team to present cloud streaming to the PlayStation 4. This allows users to access a number of hits from previous PlayStation systems on their current consoles, without having to worry about sacrificing important storage space.
500 GB Hard Drive, With the Option for Expansion – Numerous PlayStation 4 games will require a good amount of space to run efficiently. For instance, Knack will need 37 GB of hard drive space, while Killzone: Shadow Fall takes up 43 GB. Not to worry, though, as the system will come with a built-in 500 GB hard drive. In addition, and like the PlayStation 3 before it, you can remove the hard drive and expand its space, as it takes up to 1.5 TB (terabyte) — and perhaps even bigger. With all the games coming out, the bigger the better.
Play Games During the Installation Process – One big problem that plagued certain PS3 users was having to wait for a game to completely download before playing it. Seeing as how some of them were huge – 11 GB for Tom Clancy’s Splinter Cell: Blacklist, for example – it could take forever. However, some games on the PlayStation 4 have an “instant play” option, where you can start playing right away while a game installs from the disc, once you put it in the drive. It isn’t confirmed yet if the procedure is similar to downloadable games from the PlayStation Network, but the possibility is certainly there.
The Second Screen Experience – We know what Microsoft can do with its second-screen experience with Smart Glass. Sony, however, doubled that effort, making the PlayStation 4 not only accessible with the PS Vita, but also tablet devices. Using the Remote Play feature, players can use their Vita as a second screen for gaming, with just a few button presses. Meanwhile, tablet and smartphone owners can download a PlayStation app that takes things even further, like checking out in-game items or downloading content directly from the PlayStation Store.
A More Personalized Friend System – Usually, when you’re looking over player stats or who’s online, you have to resort to a plain old friend list, with only a few details here and there. With the PlayStation 4, Sony took the experience a little deeper, with the ability to build a much more detailed friend profile. You can put together content that details yourself and match it up with others, and see recommendations for games, movies and other programming with the push of a button. It’s important to know what your friends are up to, instead of just “well, they’re offline.”
Deeper Game Experiences – One glimpse at Killzone: Shadow Fall and Infamous: Second Son, and you can tell that Sony’s developers are hard at work making game experiences look as cinematic as ever. The environments are deeper, the graphics richer and the gameplay more advanced.
Tremendous Indie Support – Sony welcomed independent game developers right from the start, and the PlayStation 4 will continue to support them a hundred fold. Several indie superstars are already on board with the console, with games like Transistor, Hotline Miami 2, Octodad, Mercenary Kings and a number of others. Furthermore, with the self-publish option, developers can forego the usual bothersome fees and distribute to their waiting audience. This could be a huge feature for potential developers who don’t feel like being weighed down.
The “Share” Button – With “Share,” users don’t have to worry about getting the right kind of equipment to show others what they can do. Instead, you’ll connect with Twitch.tv – once you’ve got your account settings in place – and broadcast either through live streaming, or set up a gaming highlight that you can share with others across the PlayStation Network.
