Article: There are two versions of Minecraft; Minecraft (also known as Minecraft: Bedrock Edition) and Minecraft: Java Edition.  You will need to download the appropriate server software for whichever version of Minecraft you are running. To determine which version of Minecraft you are running, launch Minecraft and check the title screen.  If it says "Java Edition" below "Minecraft" on the title screen, you are running Minecraft:  Java Edition.  If the title screen just says "Minecraft" with no text below it, you are running the Bedrock Edition.  The server software for Minecraft: Bedrock Edition is still in it's Alpha testing phase.  It may be more buggy than Minecraft:  Java Edition. Only players on PC and Mac can connect to Minecraft:  Java Edition servers.  Players on Windows 10, Android, iPhone, iPad, Xbox One, Nintendo Switch, and PS4 can connect to a Minecraft Bedrock server. Alternatively, you can sign up for a free Minecraft server at Minehut.com.  You can also subscribe to Minecraft Realms to host a permanent server. If you plan to use your computer as a server for Minecraft, you'll need to have a fast CPU and sufficient RAM to handle the number of people you anticipate logging on to your server to play.  You will also need additional resources to run your computer's operating system, and the game itself.  The following are the recommended computer specs needed to host a Minecraft server, depending on the number of players connected:   1-3 Players:  2 GB RAM, Intel Core-Based CPUs or AMD K8-Based CPUs and better, 10 GB empty hard drive space.  3-5 Players: 3 GB RAM, Intel Core-Based CPUs or AMD K8-Based CPUs and better, 18 GB empty hard drive space.  5-7 Players: 6 GB RAM, Intel Nehalem-Based CPUs or AMD K10-Based CPUs and better, 25 GB empty hard drive space.  8+ Players: 8 GB RAM, 	Intel Nehalem-Based CPUs or AMD K10-Based CPUs at 3.6GHz or higher, 35 GB empty hard drive space with high read/write speeds recommended. You'll need a fast upload and download speed to allow players to interact with one another in real time.  The following is the recommended internet connection speeds depending on how many players are connected:   1-3 Players:  6 Mbps upload, 3 Mbps download  3-5 Players:  8 Mbps upload, 4 Mbps download  5-7 Players: 14 Mbps upload, 7 Mbps download  8+ Players:  30 Mbps upload, 15 Mbps download The software that enables you to use your computer as a Minecraft server requires Java to run.  Windows computers do not usually come with Java pre-installed. You can install a current version of Java from http://www.java.com/en/download/manual.jsp. Java is available in 32-bit and 64-bit versions. You can run 32-bit Java on a 64-bit computer, particularly if you're using an older browser that only supports 32-bit Java, but you can't run 64-bit Java on a PC with 32-bit architecture. Macintosh computers, in contrast, usually come with Java pre-installed and update it automatically. If your Mac doesn't have a current version of Java installed, you can get it from the same source as the Windows version.
