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.  |

  | 
  | 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.  |
