1x4 1 by 4 Splitter and Patch Cord

This is a device called a 1x4 splitter with patch cords. It has one input port and four output ports. Imagine a water hose with one end and a splitter that creates four new hoses. That's what this splitter does with a signal, but instead of water, it carries information. The patch cords are like short, handy hoses that you can easily connect the splitter's outputs to other devices. This lets you send the same signal to four different places at once.
