Ok, so imagine a pillar. Whatever it is supporting, like a ceiling, is pushing down on it, right? And so it would sink into the floor. But the floor also gives off a force like the ceiling, but upwards. Therefore, the pillar should crumple, but it gives off a force called compression, so as the ground and ceiling produce an inward force, the pillar applys an outward. That outward force is compression.

File compression is when you use tools to make a file take up less space on a storage device. File decompression is when you return the file to it's original size
