About how much would it cost monthly to keep a small MMO up and running on average?

If you don't even know what RAM, GB, and bandwidth mean, I can't say that you'll have much luck running an MMO server. That's critical stuff that anyone who plays video games on a computer should know.

Basically, a bit is either 1 or 0. On or off. It's what computers use to store data.

A byte is 8 bits, and generally the simplest, smallest unit of storage. Each character that you're reading right now takes up a byte of space.

A kilobyte (KB) is a thousand bytes. This post is probably around 5 kilobytes.

A megabyte (MB) is a thousand kilobytes (or a million bytes). Most MP3 music is around 5 to 8 megabytes.

A gigabyte (GB) is a thousand megabytes (or a billion bytes), and is the largest common unit of storage. My really old, crappy hard drive can store about 77 gigabytes.

A terabyte (TB) is a thousand gigabytes (or a trillion bytes). Most higher-end hard drives these days are 1 or 2 terabytes.

RAM is short for Random-Access Memory. Your computer stores data in RAM that it needs to run and load programs. Generally, more RAM means faster response times, less lag, and you can run more programs at one time. My laptop has 1 GB of RAM, which is enough to run Minecraft at a somewhat-playable 15 frames per second and have Chrome running G-mail well enough that it sometimes is able to alert me when I get a message.

Bandwidth is how much data gets sent to and from a server. Every time you load a webpage, or view an image, it adds to that page's bandwidth, because the server has to send that file to your computer.
