Raspberry Pi 4 Model B (2GB RAM)

1. What is Raspberry Pi?

• Raspberry Pi is the third best-selling computer brand in the world. It is a credit card-sized computer. You can use it to learn to code and to build electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games.

2. Does this come with a power adapter? 

• This tiny, dual-display, desktop computer doesn't come with a power adapter, but A 15W USB C power supply is needed to power the board, we recommend using the official Raspberry Pi USB C Power Supply.

3. What is the RAM size of the Pi4 board? Can I add extra RAM to the Pi?

• Raspberry Pi 4 is available in three variants - 2GB, 4GB, or 8GB.  Depending on how much RAM is required for your application, you can make a choice of the RAM.
  
  The RAM on the Raspberry Pi 1 Model A, A+, B, B+, and Pi Zero/Zero W and pi 4 is a Package on Package (POP) on top of the SoC, which means you cannot remove or swap it. 

4. What are the possibilities/Applications with Pi?

• Being one of the most powerful computers available, it has a vast multitude of possibilities! For your understanding and reference, a few are listed below.
  Replace your desktop with Raspberry Pi
  Set Up a Retro Gaming Machine
  Control a Robot
  Make a Time-Lapse Video
  Broadcast a Pirate FM Radio Station
  Build a Raspberry Pi Web Server
  Photograph the Night Sky
  Build a Network Monitoring Tool
  Turn a Raspberry Pi Into a Media Server
  Stream Live Video to YouTube
  However, do not let these hold you back. There are limitless possibilities. All that you need to do is just explore!

5. What are the basic accessories required to get started with Raspberry Pi?

• The basic components/accessories required to get started with Raspberry Pi are HDMI Cable, SD Card, and Power Supply. Opt for the original Raspberry Pi Power Supply for best results. Use of local or inauthentic cables may also void your warranty.
  We have also curated a few Raspberry Pi kits on popular demand.

6. Can I connect multiple Raspberry Pis to make a faster computer?

• Sort of, but not in the way you might want to do it. You cannot simply make a more powerful computer, to play games faster for example, by bolting together smaller ones. You can network computers to create a cluster computer, but you do need to modify your software to work in this distributed fashion. We've put together a tutorial on how to build a Raspberry Pi cluster.

7. Can I run Windows 10 on the Raspberry Pi?

• You cannot run Windows 10 on the Raspberry Pi. There is however a special "Internet of Things" version of Windows 10 that runs on the Raspberry Pi 3B and 3B+ called Windows 10 IoT. Windows 10 IoT does not have a graphical desktop and is intended for use in embedded devices.
  
  You may see reference to Windows 10 running on the Raspberry Pi online. This is because the community has devised a way to run regular Windows 10 on the Raspberry Pi. Although it will run, it runs extremely slowly so is not of any real use. Rather, it is a proof-of-concept. Microsoft does not sanction running Windows 10 on the Raspberry Pi.

8. Is it safe to just pull the power?

• No, not really - you may corrupt your SD card if you do that. We recommend issuing the ‘sudo halt’ or ‘sudo shutdown’ command before pulling the power. This ensures that any outstanding file transactions are written to the SD card and that the SD card is no longer 'active'. Pulling the power during an SD card transaction can occasionally corrupt the card.
