Trash is often classified as a worthless item that takes up space that would be better used to house something more useful. Garbage can be broken things, obsolete items, or things that have been left small and that currently have no valuable purpose for you. Trash includes, but is not limited to, scrap metal, used building materials, appliances, accessories, or used furniture. Garbage cannot be stored for more than 30 days in a place that is visible from the street or from the public right of way.
See Eugene Code 6.800 for more information. Like any bond, a junk bond is an investment in debt. A company or government raises a sum of money by issuing promissory notes that indicate the amount it is borrowing (the capital), the date on which it will return the money (due date) and the interest rate (coupon) that it will pay you for the money lent. The interest rate is the profit that the investor will get from lending the money.
Junk files are temporary files that are created so that the computer or phone can perform specific tasks that are no longer needed. At one point, these files were useful, because programs, applications, and operating systems need to create temporary files to execute computer tasks. But after serving their purpose, these files become useless garbage.
