The Multimedia over Coax Alliance (MoCA) is a group of companies that work together to make it easy for you to send and receive multimedia data (like TV shows, movies, and music) over the coaxial cables in your home.
Just like how we have roads for cars to travel on, your home has different kinds of cables that carry different things like picture and sound from your TV to your cable box, or data from your router to your computer. Coaxial cables are one of the most popular types of those cables, and they are special because they have a copper wire running down the middle of them, which is surrounded by insulation and a metal shield.
What MoCA does is make it so that you can use those coaxial cables to send more data than usual. They created a special technology that allows the data (like your favorite TV show or your family’s pictures from your vacation) to travel through the wires as electric signals. These signals can travel in different lanes, like cars on a road, so your internet and TV won’t slow each other down.
By working together, companies in the MoCA alliance help make it so that you can easily use coaxial cables to transmit data in your own home without any difficulty. So now when you watch your favorite movie, you can thank MoCA for working hard behind the scenes to make it happen!
