CRC
Abbreviation for cyclic redundancy code, which is a number derived from,
and stored or transmitted with, a block of data in order to detect corruption.
By recalculating the CRC and comparing it to the value originally transmitted,
the receiver can detect some types of transmission errors.
CSR
Abbreviation for certificate signing request. A complex text file generated by
a Web server to identify and authenticate systems that seek connections to other
systems. The digital signature that is present in every CSR contributes to secure
identification of systems.
When a remote access controller is present on a system running Server
Administrator, the CSR that comes with the RAC belongs to Dell. If your
company wants to generate its own CSR, you can request a unique CSR from
a certificate authority and overwrite the Dell CSR.
