Channel - An information path from a discrete input to a discrete output. Component - Any electrical or electronic device Contractor - The person or persons, manufacturer, firm, partnership, corporation, vendor or combination thereof, who have entered into a contract with the AGENCY, as party (s) of the second part or legal representative Controller Unit - That portion of the controller assembly devoted to the operational control of the logic decisions programmed into the assembly CPU - Central Processing Unit CTS - Clear To Send DAT Program - The AGENCY’s Diagnostic and Acceptance Test Program dB - Decibel dBa - Decibels above reference noise, adjusted DC - Direct Current DCD - Data Carrier Detect (Receive Line Signal Detector) DIN - Deutsche Industrie Norm DRAM - Dynamic random access memory. Random access means that the processor can access any part of the memory or data storage space directly rather than having to proceed sequentially from some starting place. DRAM is dynamic in that it needs to have its storage cells refreshed or given a new electronic charge every few milliseconds.
