Updating a ps3
In summary, early PS3 consoles such as the 60GB and 20GB launch PS3 consoles were backwards compatible with PS2 games because they had PS2 chips in them.
Some later models, most notably the 80GB Metal Gear Solid PS3 consoles are also backwards compatible, through partial software emulation in this case since they no longer had the PS2 CPU in them, although they do have the PS2 GPU in them, allowing for reduced backward compatibility through hardware-assisted software emulation.
The base operating used by Sony for the Playstation 3 is a fork of both Free BSD and Net BSD called Cell OS.
The process of updating is almost identical to that of the Play Station Portable, Play Station Vita, and Play Station 4.
The Play Station 3 uses the Xross Media Bar (XMB) as its graphical user interface, which is also used in the Play Station Portable (PSP) handheld console, a variety of Sony BRAVIA HDTVs, Blu-ray disc players and many more Sony products.
XMB displays icons horizontally across the screen that be seen as categories.
Unlike the Software Development Kit (SDK) for mobile apps, Sony's Play Station 3 SDK is only available to registered game development companies and contains software tools and an integrated hardware component.
Due to the fact that it requires a licensing agreement with Sony (which is considered expensive), a number of open source and homebrew PS3 SDKs are available in addition to a number of leaked PS3 SDKs.
Furthermore, the Play Station 3 provides printing support.
This feature enabled users to install an operating system such as Linux, but due to security concerns, Sony later removed this functionality through the 3.21 system software update.
According to Sony Computer Entertainment (SCE), disabling this feature will help ensure that PS3 owners will continue to have access to the broad range of gaming and entertainment content from SCE and its content partners on a more secure system.
It can for example print images and web pages when a supported printer is connected via a USB cable or a local network.
However, only a selection of printers from Canon, Epson, and Hewlett-Packard are compatible with the PS3.
Furthermore, the Play Station 3 is able to play Blu-ray Disc and DVD movies as well as audio CDs out of the box, and also capable of adopting streaming media services such as Netflix.
