This means that files are managed using special unique identifiers derived from the _contents_ of the file, rather than human-assigned file names (specifically, the MD5 hash). This has a number of advantages: * Files can be stored and replicated across a cluster of servers without requiring a central name server. * Both the server and client systematically validate data integrity because the checksum is built into the identifier. * Data duplication is minimized—two files with the same contents will have in the same identifier, and will not be stored twice. @@ -119,7 +119,7 @@ You can also download individual files: -With a local copy of the file, we can do some computation, for example computing the md5 hash of the complete file: +With a local copy of the file, we can do some computation, for example computing the MD5 hash of the complete file:
