The Raspberry Pi is a credit card–sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools - - wikipedia 
# Video
The video controller can emit standard modern TV resolutions, such as HD and Full HD, and higher or lower monitor resolutions and older standard CRT TV resolutions.
As shipped (i.e., without custom overclocking) it can emit these: - 640×350 EGA - 640×480 VGA - 800×600 SVGA - 1280×720 720p HDTV - 1280×768 WXGA - 1280×800 WXGA - 1280×1024 SXGA - 1366×768 WXGA - 1400×1050 SXGA+ - 1600×1200 UXGA - 1680×1050 WXGA+ - 1920×1080 1080p HDTV
The Raspberry Pis can also generate 576i and 480i composite video signals, as used on old-style TV screens and less-expensive monitors through standard connectors either RCA or 3.5mm phono connector depending on models - raspberrypi.org

#Raspberry Pi 2
In early February 2015, the next-generation Raspberry Pi, Raspberry Pi 2, was released.
Raspberry Pi Model B Revision 1
The new computer board is initially available only in one configuration (model B) and features:
- Broadcom BCM2836 SoC
- Quad-core ARM Cortex-A7 CPU
- VideoCore IV dual-core GPU
- 1 GB of RAM
- Remaining specifications similar to the previous generation model B+
