Answer:
Street prices are affected by the extent of illegal commercial copying. The availability of inexpensive, high-quality illegal copies reduces the demand for legal copies to the extent that some users buy illegal copies instead of legal ones.
Well, it is safe to turn a computer on without a RAM, but you can't really do it. RAM is one of the essential components in computers without which you can't really use a computer. You can turn it on, however, nothing will appear on your screen and the system won't boot. So, technically, it is safe, but it won't do anything to your computer as it cannot run without RAM.

Answer:
Data redundancy.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
Data redundancy is the name of situation where the same data is stored unnecessarily at different places.
Simply stated, data redundancy can be defined as a condition which typically involves storing the same data in multiple storage locations. Thus, data redundancy connotes the unnecessary repetition of the same piece of data (informations) either deliberately or for some specific reasons.
