Think about it, the answer is obvious! Think about it and do your own homework.

an answer would be nice, slithmister.

Not when your new to an information system class, i only know what one of these things are and can guess one. Just because you know doesnt necessarily mean everyone else knows, no need to be an arrogant git And yes, a comment would be nice wouldnt it? What do you think i do it for no reason? Why dont you think about it eh, maybe i cant? I think at level 38 i wold now know how to comment.

- I think the most important is the backup part, to ensure that accidentally destroyed data could be restored. This one is vital. - The security part has also to be considered, because data could be destroyed through malicious software, and measures must be taken to reduce this. - intelligent upgrading and networking are important functions, but are not much worth without backup and security. Here some information about those issues: 1) "In information technology, backup refers to making copies of data so that these additional copies may be used to restore the original after a data loss event. These additional copies are typically called "backups." Backups are useful primarily for two purposes. The first is to restore a computer to an operational state following a disaster (called disaster recovery). The second is to restore small numbers of files after they have been accidentally deleted or corrupted. Backups are typically that last line of defense against data loss, and consequently the least granular and the least convenient to use."

In the general sense, security is a concept similar to safety. The nuance between the two is an added emphasis on being protected from dangers that originate from outside. Individuals or actions that encroach upon the condition of protection are responsible for the breach of security. The word "security" in general usage is synonymous with "safety," but as a technical term "security" means that something not only is secure but that it has been secured. In telecommunications, the term security has the following meanings: A condition that results from the establishment and maintenance of protective measures that ensure a state of inviolability from hostile acts or influences. With respect to classified matter, the condition that prevents unauthorized persons from having access to official information that is safeguarded in the interests of national security. Measures taken by a military unit, an activity or installation to protect itself against all acts designed to, or which may, impair its effectiveness. Security has to be compared and contrasted with other related concepts: Safety, continuity, reliability. The key difference between security and reliability is that security must take into account the actions of active malicious agents attempting to cause destruction."

The word is also used by audiophiles to describe the replacement of a product with a better quality product with the aim of bringing enhancements to sound quality."

Networking, routers, routing protocols, and networking over the public Internet have their specifications defined in documents called RFCs. Computer networking is sometimes considered a sub-discipline of telecommunications, computer science, information technology and/or computer engineering. Computer networks rely heavily upon the theoretical and practical application of these scientific and engineering disciplines."
