The computer has come so far in the last ten years. Years ago you needed to have all data that was loaded onto a computer on a disk of some sort. If you needed to add something to your computer, you just put the disk in and waited for it to load the information into your computer. If you were doing some work, you did what you had to do, popped in a disk and loaded that work onto a disk. Moving work within the computer was nowhere near as prevalent as it is today. It seemed genius and very forward thinking to be able to load all of your work onto a thin disk that could be carried in any briefcase, backpack or even in a purse if needed. It was a fabulous way to keep current with the workings of a computer.
Now software is almost obsolete. Anything needed on a computer can be downloaded directly from a computer. Just turn on your computer, use a search engine to find the information you need, click the mouse and download the information immediately. It will load directly onto your computer and it is ready for use immediately, or almost immediately. Some of these applications are copyrighted and you need to agree to terms before using the software, but for the most part this is an easy way to streamline computer use.
The floppy disk, or at least disk will never be completely obsolete. It is still necessary to back up your most important files with a hard copy. Computers can crash and lots of information can be lost in cyber space or destroyed altogether. It is good to know that we do have a way to protect our hard work.
