A "storage grid" is made up of a number of storage servers. A storage server
has direct attached storage (typically one or more hard disks). A "gateway"
communicates with storage nodes, and uses them to provide access to the
-filesystem over protocols such as HTTP(S), SFTP or FTP.
+file store over protocols such as HTTP(S), SFTP or FTP.
Note that you can find "client" used to refer to gateway nodes (which act as
a client to storage servers), and also to processes or programs connecting to
the user connects to it over HTTPS or SFTP. This means that the operator of
the gateway can view and modify the user's data (the user *relies on* the
gateway for confidentiality and integrity), but the advantage is that the
-user can access the filesystem with a client that doesn't have the gateway
+user can access the file store with a client that doesn't have the gateway
software installed, such as an Internet kiosk or cell phone.
