SMB (Server Message Block): An application-level networking protocol that gives
shared access to files, serial ports, printers, and other data transfer between
nodes on a network. SMB can also be used to access different subnets over the
Internet. Computers on a network that don't share their individual hard disk drives,
use SMB to gain access to shared drives, volumes, files, printers, or other devices
on a network. It is mainly used by Microsoft Windows-enabled computers.
SMB (Small to Medium-Size Business): A small business generally has less than
100 employees. A medium business has from 100-999 employees.
SMTP (Simple Mail Transfer Protocol): The standard protocol for sending emails
over the Internet typically used in conjunction with POP or IMAP mail servers so
that end users can receive, save, and store email.
SSH (Secure Shell): A protocol and group of standards that provide confidentiality
and integrity of data as it is exchanged between two or more computers or from a
storage/server device to an accessing computer. SSH uses encryption and
authentication codes to establish a secure communication channel. It is most often
used to log into a remote computer or other device to execute commands.
SSL: Secure Sockets Layer. SSL is a protocol used to transmit files over the
Internet using a private key to encrypt the data. SSL was originally developed by
Netscape and is now an industry standard. The NSS supports FTPS which is FTP
over SSL.
Striping: A method of concatenating multiple disk drives into one logical storage
unit. Striping involves partitioning each drive's storage space into stripes which
may be as small as one sector (512 bytes) or as large as several megabytes.
These stripes are then interleaved round-robin, so that the combined space is
composed alternately of stripes from each drive. In effect, the storage space of
the drives is shuffled like a deck of cards. The type of application environment, I/O
or data intensive, determines whether large or small stripes should be used.
T
Terabyte (TB): For data storage capacity usage, terabyte is equal to 1024
gigabytes.
TFTP (Trivial File Transfer Protocol): A simple file transfer protocol used to transfer
small files between hosts on a network. TFTP works like a very basic form of FTP.
