The Raspberry Pi 4 Model B is one of the popular Raspberry Pi range of single board computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior generation Raspberry Pi 3 Model B+ while retaining backward compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems.

Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, up to 8 GB of RAM, dual-band 2.4 / 5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on). The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.

MUSTATION is a terminal without CPU, hard disk, enabling users to surf the Internet, play games, and can realize Internet application of ASP, instant Messenger, Private E-mail, and office suites software, photo manager software, multimedia software and so on with no need to purchase standard host.
Mustation could turn 1 pc into 2-30 pc or more based on the host computer and shared the information resources with host .Each user can visit host resources safely, independently and synchronously. Take an example, there are 10 staffs in an office, you only need to purchase I set standard computer, another 9 user only need to user thin client MuStation .
As well know. Standard Computer = Monitor(display) + traditional host (with CPU/HD/CD-ROM) + keyboard+ mouse
Mustation = host (with no CPU/HD/CD-ROM)
For example, There are 31 staffs in your company. Only need to purchase 1 set standard computer. The rest (30) computers only need to use MuStation The rest 30sets user share the information resources together with the host of the standard computer. Each user can visit host of standard computer resources safely, independently and synchronously.
