PlayStation 4 (English: PlayStation 4, or PS4 for short; Japanese: プレイステーション4?) is a video game platform developed by Sony Computer Entertainment. It was announced as the successor to the PlayStation 3 during a conference on February 20, 2013. It is the fourth video game system produced by Sony after the PlayStation 3 and PlayStation 2 systems. The PlayStation 4 competes as an eighth-generation video game system with the video game system developed by Microsoft Xbox One and Wii U developed by Nintendo. The PlayStation 4 was launched in North America on November 15, 2013, November 29, 2013 in Europe and Australia, and December 14, 2013 in Saudi Arabia.
Unlike the PlayStation 3 with a Cell processor, the PlayStation 4 uses an AMD processor based on the X86-64 instruction set, whose goal is to facilitate the process of developing video games on the platform, unlike the Cell processor, which many developers faced problems in exploiting its capabilities due to the difficulty of developing using it. The new processor attracted a wider group of developers. These changes highlight Sony's efforts to improve upon lessons learned during the development, production, and release of the PlayStation 3. Other notable hardware pieces include 8GB of unified GDDR5 memory, a faster Crystal Drive, and dedicated chips for audio, video, and background processing. Sony has developed functions forks to the fourth generation, which will include the improved Sixaxis motion sensor. In addition to a place to sense the movement of the fingers on the front side of the control hand, which will add a more interactive element during the game. It includes an internal vocal mic in the DualShock. And a rear exit to connect the headphones, in order to deliver a new experience to the player by hearing special sounds from the control hand that are different from what is heard on the TV screen. The SELECT and START button was replaced by OPTIONS, and the SHARE button was added, which allows players to save clips or images of their games in the device and live broadcast their games that they play on Internet broadcasting services such as Ustream and Twitch.
The PlayStation 4 contains new services that were not available in the PlayStation 3 and PlayStation 2, such as the PlayStation application on Android and iOS. The app allows gamers to see what their friends are playing and view their profiles or recent activity. In addition, they will be able to chat with friends and receive notifications, alerts, and invitations to play a game. Also using Android and iOS as a keyboard to appear on the PlayStation 4 screen. The application also provides users with the ability to browse the PlayStation Store and learn about the latest games. And the PlayStation Now service, which enables you to play PlayStation 4, PlayStation 3, and PlayStation 2 games using tablets, mobile phones, and TV screens from Bravia and Samsung. And the “Remote Play” service, which allows owners of the PlayStation Vita and Xperia devices to play PlayStation 4 games on their devices without the PlayStation 4.
