Elliptic Curve Cryptography. An alternative to the well-known RSA algorithm for asymmetric encryption; has been approved for the generation and verification of digital signatures. ECC technology is based on a highly complex mathematical model: calculation of discrete logarithms (DL) in suitable amounts. The complexity of ECC means, among other things, that keys and parameters can be shorter than with other methods without compromising security. _____________________________________________________________________________
An electronic method of checking the integrity of data stored in DRAM. ECC is a more elaborate error-detection method than parity; it can detect multiple-bit errors and can locate and fix single-bit errors. ECC usually uses three additional bits per byte of data (compared to one additional bit for parity).
This generally refers to memory chips or motherboards that support the checking for, and possibly correcting of, memory errors in full-parity memory chips....
Error Checking and Correcting. Memory technology with extra bits added for detecting bad memory and often recovering its contents.
Mathematically determined rror orrection ode specified in the standards that represents data and is recorded with that data to enable limited correction of read errors.
(Error Correction Code) A hardware in the drive controller which allows correction of various read errors. Can typically correct a single burst error of 11 bits or less. This maximum error burst correction length is a function of the controller. With some controllers the user is allowed to select this length.
Eliptic Curve Cryptographya is a form of public-key cryptography that is faster (10 X) and requires less memory and processing than RSA technology.
Abbreviation for error correction code.

Exchange Carrier Code. A four-character code assigned to CLEC s by Telcordia Technologies. The Exchange Carrier Code and Company Code (assigned by NECA) identify the CLEC to the companies from whom they buy (or lease) telephone numbers, dial tone, facilities, etc. Also known as AECN .
Error Correction Code: a system of scrambling data and recording redundant data in stored data in order to enable the detection of errors that can be corrected by the device's controller when the data is read. ECC memory can detect up to 4-bit memory errors; only single-bit errors, however, can be corrected. See also CRC.

Error Correction Codes. Onboard system codes that correct errors, in real time, without the drive having to perform retries, thus not affecting processing time.
An error correcting code specifies how to add extra information to data bits in a fashion that allows corrections to be made to the data if one (or possibly more) of the resulting bits is changed. The most common error correcting codes have the ability to correct a single bit error and detect double bit errors. To add SEC-DED (single error correction - double error detection) to a word of 64 bits, an 8 additional bits are usually used.
Error Correction Code. The method of error correction used in an earlier version of Windows Media Services. Redundant data is sent with the data stream to detect and control single bit errors in the data stream. In the current version of Windows Media Services, streaming errors are corrected through UDP resend.
Error Correction Code. This code is used to correct data errors and is recorded at the end of each sector. By this ECC, the byte error rate of around 1E-9 can be corrected to around 1E-12.
Energy content curves. A set of curves that establishes limits on the amount of reservoir draw-down permitted to produce energy in excess of FELCC.
A complicated algorithm is used to scramble and code the user data into a redundant form that is added to each sector. During playback, this redundant information is decoded and helps to detect and correct errors that may arise due to read errors, such as those caused by scratches, dust, or fingerprints on the media. A sector length is fixed by industry standards, but because errors in digital data are more critical than errors in audio data, the digital data formats use additional ECC code to insure a higher write accuracy, and contains less user data within each sector.
Generally refers to memory chips, or motherboards that support this type of behavior in full-parity memory chips. ECC memory uses some extra memory on the memory chips for parity information and checks to see whether a memory error has occurred. If a minor memory error occurs, the ECC logic will handle it. With full-parity memory (one step below ECC), you will be alerted of a memory error and your system will stop. With non-parity memory, you will experience random results, usually crashing, and possible data corruption.
ERROR CORRECTION CODING. An encoding method that detects and corrects errors at the receiving end of data transmission. ECC is used by most modems.
(Error Correction Code) Refers to parity error detection and correction within memory or cache (for example, SIMM). Depending on the ECC SIMM, single-bit or double-bit parity errors can be detected but not corrected, or detected and corrected automatically.
Error Correction and Checking - A check data block is added to a data packet of the communication channel or on a disc by which a receiving system can detect the small errors.

Either "error correction (or correcting) code" or "error checking and correcting." Allows data that is being read or transmitted to be checked for errors and when necessary, corrected "on the fly." It differs from parity-checking in that errors are not only detected but also corrected. ECC is increasingly being designed into data storage and transmission hardware as data rates (and therefore error rates) increase.
Error correcting code. A code stored on an RFID tag to enable the reader to figure out the value of missing or garbled bits of data. It's needed because a reader might misinterpret some data from the tag and think a Rolex watch is actually a pair of socks.

Error Correcting Code. The diagnostic code used to correct data storage errors and to isolate hardware failures. Based on a concept of simultaneous polynomial equations, the read-back process generates a "correction" profile that is exclusive-OR'ed over the incorrect data. All ECCs have a very small, but finite failure rate; that is, some uncorrectable errors will either appear as correctable or appear as having no error at all. In either situation, bad data is passed as verified and valid.
An acronym for Error Checking and Correction. ECC enables parity checking and can detect and correct memory errors on the system board.

(Elliptic Curve Cryptosystem) A method for creating public key algorithms, which some experts claim provides the highest strength-per-bit of any cryptosystem known today. Its algorithms accept an encryption key but then add extra numbers representing the coordinates of points on an imaginary wiggly curve as it crosses an imaginary line. Its complicated algebraic approach allows shorter keys to produce security equivalent to longer keys in other cryptosystems (such as RSA). Shorter keys mean the encryption and decryption can be performed relatively quickly and with less computer hardware. Numerous experts believe ECC will eventually enjoy widespread use.
Elliptical Curve Cryptosystem, a unique method for creating public key algorithms based on mathematical curves over finite fields or with large prime numbers.
