DEFINITION of continuous data protection
Continuous data protection (CDP), also called continuous backup, is a storage system in which all the data in an enterprise is backed up whenever any change is made. In effect, CDP creates an electronic journal of complete storage snapshots, one storage snapshot for every instant in time that data modification occurs.

DEFINITION of CRC-4
CRC-4 (Cyclic Redundancy Check 4) is a form of cyclic redundancy checking (a method of checking for errors in transmitted data) that is used on E-1 trunk lines. CRC-4 is structured in a multiframe consisting of 16 frames numbered 0 to 15.
DEFINITION of daemon
A daemon (pronounced DEE-muhn) is a program that runs continuously and exists for the purpose of handling periodic service requests that a computer system expects to receive. The daemon program forwards the requests to other programs (or processes) as appropriate.

DEFINITION of DCE
1) In network computing, DCE (Distributed Computing Environment) is an industry-standard software technology for setting up and managing computing and data exchange in a system of distributed computers.
DEFINITION of deadlock
