A data can be lost due to many causes. Few of them are :-
Intentional Action - If somebody intentionally deleted your data.
Unintentional Action -
Accidental deletion of data by anyone.
Misplacement of memory device containing data.
Power failure.
Hardware failure.(hard disk crash)
operating System corruption.
Natural disaster like flood, fire etc.
These are few main reasons of data loss. But there is good news, you can recover all your lost data using a good file recovery software. Windows Data Recovery by Stellar Phoenix is one such software.
Yes, it does. If the data are sample data, than the divisor is N. If the data are the entire population, than the divisor is N-1 is account for the loss of one degree of freedom in the calculation of both the mean and the standard deviation from the same data.
The main loss is the correlation, if any, between the variables. You also lose the exact value of individual data points.
Data formats: It is formating all data file from pcs.whatever it is not use.suppose when data is full,and some data we want to delete it.. Data collection: It is the collection of new data file.when new data is collecting..
Metadata is "data about data". There are two "metadata types;" structural metadata, about the design and specification of data structures or "data about the containers of data"; and descriptive metadata about individual instances of application data or the data content.
Ungrouped data is data that is not grouped in a specific order. Grouped data is a set of data that has unique characteristics in common.
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.
If you are facing data loss then search your data is trash/recycle bin. If data is not there, opt for a data recover software and get it back.
So you can backup your data if data loss occurs.
Best way to avoid data loss is by taking backup. If you take backup at regular intervals. you will not have to face the problems due to data loss.
The best way to protect against accidental data loss is to back-up your data frequently.
Best data loss prevention is taking backup of the data at regular intervals. If still it remains insufficient you may opt for data recovery software, which can recover your lost data.
Fire, Flood, Operator Error are some of the ways data loss can be huge
lose data or a loss of data i think
Nonloss-decomposition is data normalization without the loss of information.
It can cause data loss, data corruption, or hardware failure. These do not always happen, but crashing a computer will make all 3 of these things more likely.
Symantec offers data loss prevention software. Here is the website for this product www.symantec.com Business Products.
There are few precaution following which you can avoid data loss. These precautions are :- Avoid Physical damage Be careful while deleting some data. Keep anti-virus updated. Try to keep memory from Power Failure, Natural Disaster, Firmware Corruption etc. maintain a Backup of all necessary data. Despite taking precaution, data loss still happens. If it happen, data recovery software are available to help you. One such good software is Stellar Phoenix Windows Data Recovery. This software can recover data from Windows 8, 7, Vista, XP, 2003, 2000 etc in no time.
