WHAT IS ARCHIEVE :

An archive is a collection of computer files that have been packaged together for backup, to transport to some other location, for saving away from the computer so that more hard disk storage can be made available, or for some other purpose. An archive can include a simple list of files or files organized under a directory or catalog structure (depending on how a particular program supports archiving).

What Is Indexing?

What is an index? The Random House Webster's Dictionary defines it as an "alphabetical list of names, places, and topics with the page numbers on which they are mentioned." Indexes are often confused with concordances, which leads us to the question: What is a concordance? The same dictionary defines it as "an alphabetical index of the principal words in a book with their immediate context." The dictionary entries sound similar because indexes and concordances are alphabetical, list page numbers, and consist of 'main heading' words; however, there are many differences. The American National Standards Institute (ANSI) gives us this definition of an index: "A systematic guide to items contained in or concepts derived from a collection."
