Cloud Drives can be purchased and administered just like a hard-wired network, with the same types of permissions. This also means that you don't particularly need any specific microcomputer to get work done, just one that can connect to the Internet. If your resume file (MyResume.docx) was on a Cloud Drive, it wouldn't require back up, as the Cloud Service Providers (CSP) like Google, Microsoft, or DropBox would provide back up automatically. That's the Cloud, or at least a small part of it. With the cloud, if the original internal hard drive contents of a computer are corrupted or lost, like in a fire, the internal hard drive's contents are still intact at a different location an off-site hard drive. The problem with backing-up to an external hard drive is that its contents are also lost if it's not taken off site. To prudently back up a hard drive, it makes sense to back-up to an external hard drive. One disadvantage to regular internal hard drives is that they have to be backed up on a regular basis. Servers are computers that store/send out data. a lot of dummy terminals use the Cloud, which are computers whose sole purpose is to open data stored in the Cloud or use the Cloud's resources only when they need it.

The Cloud is simply using computer resources like a hard drive or software that exists on another computer connected by a network, typically the Internet.
