context_page_description: The Xbox 360 technical specifications describe the various components of the Xbox 360 video game console. The console features a port on the top when vertical to which a custom-housed hard disk drive unit can be attached in sizes of either 20, 60, 120, 250, 320, 500 GB; and as of April 2015 all 2.5" SATA Hard Drives up to 2 TB, the user can use the format option from system settings to utilize the new HDD. Inside, the Xbox 360 uses the triple-core IBM designed Xenon as its CPU, with each core capable of simultaneously processing two threads, and can therefore operate on up to six threads at once. Graphics processing is handled by the ATI Xenos, which has 10 MB of eDRAM. Its main memory pool is 512 MB in size.
context_section_description: The Xbox 360 features three USB 2.0 ports (two on the front, one on the back). The Xbox 360 S, however, has five USB 2.0 ports (two on the front, three in the back) along with a dedicated Kinect port. The Xbox 360 E has four ports (two on the front, two on the back) and a dedicated Kinect port. These are used for connection of accessories such as wired controllers, the wireless networking adapter, the Xbox Live Vision camera and USB storage devices. Although the number of wired controllers is limited by the number of ports, up to four may be used through the use of a USB hub.
  The Xbox 360 also features wireless connectivity of accessories via a proprietary 2.4 GHz radio system. This is mainly used to connect the official wireless controllers, but is also used for other devices such as the wireless racing wheel and wireless headsets. With the exception of some rhythm game controllers, and the Fanatec CSR wheel, this wireless connectivity is limited to first-party Microsoft accessories.
  The Xbox 360 can connect to Xbox Live over the Internet through a variety of networking interfaces.
  Original style consoles also have two front-mounted memory card slots for the system's proprietary Memory Unit. These can be used to transfer profile and game data from one Xbox 360 to another. Memory Units up to 512 MB are available from Microsoft. The "Arcade" model formerly came with a 256 MB Memory Unit, but with the Jasper motherboard revision of September 2008, the "Arcade" model began to include 256 MB of built-in flash memory. This was later increased to 512 MB. The memory card slots were replaced with USB ports on the newer Xbox 360 S models.
  The Universal Media Remote can be used to control several functions of the console, including the Windows Media Center functions if connected to the network. It communicates with the console via infrared through a receiver port on the front of the console.
  All standard controllers for the system feature a 2.5 mm headset jack to allow the use of wired headsets for voice chatting. They also feature a custom USB connector, which is currently only used for connection of the chatpad keyboard accessory.
  Various other accessories for the console exist, such as decorative faceplates to change the physical appearance of the console.
