With primary research, you are collecting data yourself. i.e. if the question was how many red cars drive past in 1 hour you go out and count the cars but if the question is how many people gave up smoking in 2006 you look at the records, you don't ask everyone if they gave up somking in 06. Secondry data is not your own research basically.

Companies use decision support system when solving problems or making important decisions. A DSS is used to compile data, knowledge and documents in order to make informed decisions.
A data warehouse is a centralized pool of data. Data warehouse is basically a repository where large amount of data is stored . The advantage of data warehouse is that we can archive the data that is not used in a long time.
Data and information is stored so that workers will be able to come back to the information easily. Without this type of system, human service organizations would take too long to help people.
reaserch
It seems like there is a typo in the word "REASERCH." Assuming you meant "research," it refers to the systematic investigation into a subject to discover facts, theories, or applications. Research involves gathering information, analyzing data, and drawing conclusions to contribute to knowledge and understanding in a particular field.

Computers are mainly used for complex computations and simulations, but they are also often used for data collection and to analyze large quantities of data.
Secondary Memory-: is long term storage device which uses the help of input and output channels to access information.The content in it must first be copied into the primary storage (RAM) for CPU to process . It does not lose the data when device is powered off .It is nonvolatile.Eg: Hard Disk(HD),Floppy ,CD.Its Ram-random access memory to the device 3.5 &5.7 .
it is primary data
The difference between primary data and secondary data is that primary data is the information from the original research.
