Quantum A-Series manual Degree Celsius C is a unit of temperature

Glossary

C		C	The degree Celsius (°C) is a unit of temperature.
		Cache	Specialized RAM used as a buffer between a fast CPU or I/O
			channel and storage which has a relatively slow access time (for
			example, cartridge or diskette), to avoid slowing down the
			former.
		Cartridge Tape cartridge. Super DLT tape II or SDLTtape 600A.
		Cartridge Receiver At media insertion, the cartridge receiver assembly is
			responsible for guiding the media into its operating position,
			opening the door, unlocking the cartridge brakes, and securing
			the media for operation. At media ejection, the cartridge receiver
			assembly reverses the process and automatically ejects the
			cartridge a fixed distance from the front of the tape drive.
		CE	Council of Europe.
		CFR	Code of Federal Regulations (United States).
		Client	This could be a standard FTP client or the built-in FTP client
			embedded in the SDLT 600A firmware.
		CSA	Canadian Standards Association, also known as CSA
			International.
		CTM	Cartridge Tape Module. The main function of the CTM is to
			provide the magnetic recording media used by the tape drive to
			store customer information. The CTM also provides the
			protective cartridge, which allows the media to be removed and
			stored safely.
		CUP	Code Update (a firmware update).
		Data Compression A process that reduces the amount of storage space
	D
			required to hold a particular block of data. Data transfer speed
			and total media capacity are affected by the data compression
			achieved. In accordance with industry practice, a typical
			compression ratio is 2:1 of data storage. Actual compression
			ratios achieved depend on the redundancy of data files being
			written.
		dB	A Decibel is a logarithmic unit of sound intensity; 10 times the
			logarithm of the ratio of the sound intensity to some reference
			intensity.
		DC	Direct Current is the continuous flow of electricity through a
			conductor such as a wire from high to low potential.
