ECC Error correcting code
Full spelling: Error Correcting Code
Field:
Semiconductor memory ECC
Network technology ECC |
The occasion where it reads out the data from the storage unit and the like, it is the redundant data which is added separately from the original data in order to correct the error of the data. In addition, it is that kind of function. Storage unit and the bus such as the server machine where high reliability is required (the channel) it is utilized.

ECC memory
Reading: ishishimemori
Full spelling: Error Check and Correct memory
Field:
Semiconductor memory RAM ECC memory |
|
With ECC memory for the computer, it makes the data for error correction of 8 bits correspond concerning the memory 64 bit, when the inside 1 bits of 64 bits reach erroneous value, detecting this, it corrects.
In addition, when 2 bits or more reaches simultaneously erroneous value, correction is not possible, but it is possible to detect the fact that error occurs.
Error of the data is detected, but instead of needing many redundant data in comparison with the parity check which cannot do correction, error of the data occurring, to continue to drive either problem without it is possible the system. |
ECHONET
Reading: Echo net
Field:
LAN Foam/home network ECHONET
|
The echo net consortium which the Japanese major electrical machinery and appliances manufacturer and the like establishes has lectured, the electrical power service line inside home and standard of the network which utilizes the radio. Because transmission speed 9,600bps and it is slow, it is located as network in order to do the control of the home appliance equipment. ECHONET the communications network through the gateway where , besides the fact that the equipment is controlled directly from the controller which is inside ECHONET, also the control which is due to remote manipulation has become possible. Also remote maintenance such as other than and escaping gas notification the remote manipulation by the user himself by utilizing this gateway, can do. We complete the standard of ECHONET, in the future it is ECHONET correspondence service and the schedule where the corresponding equipment keeps appearing.

Eclipse
Reading: Eclipse
Field:
Programming environment for software development Eclipse |
. The Java developer focusing on we have spread quickly, it is expected that it becomes standard of the common platform of software development.
The research result of the development tool research project which the IBM corporation was advancing from 1999 being something which is made shape of the software, to open source it was converted in 2001 November, anyone gratuitous and procurement alteration it reached the point where it re-can distribute.
Eclipse is not the mere development tool, it is called “the common platform” of the development tool. As for this, being because function in the form of plug in it can add freely from after, the UML-related tool and the test tool and various programming languages etc are prepared. The number reaches to several hundred types.

ECM Enterprise contents management
Reading: [ishiemu]
Full spelling: Enterprise Contents Management
Alias:
Enterprise contents management
Field:
Enterprise information system business system ECM |
It is technology and the system in order it accumulates the information in enterprise and organizing,
Although it reaches the point where it can make the record accumulation of mass information easy with the progress of digital technology, information increases in large quantities, joint ownership and use of efficient information rather becoming difficult depending upon the proliferation and diversification etc of below, the media and the format with the competition intensification between the companies in the background, it is the concept which appears in around 2000.
As the worldwide authority of ECM AIIM which carries out direct role in regard to understanding, introducing and using of with, “ECM, the contents and the document which it is related to the process of organization collection management accumulation technology in order it protects & to distribute, the tool, technique” have been defined.
