A GED is also known as a General Equivalency Degree. This can be received by taking some tests and proving that you have received a high level of high school education. There are a lot of employers who will accept this as equal to a diploma. A diploma is what you will receive when you graduate to prove that you were able to pass the various subjects that you have tackled.
You should always remember that a GED cannot be compared to the college diploma which you get after you have finished a bachelor’s degree. But, it can be compared to a high school diploma. If you would be applying for the military, a high school diploma is required.
