It may have the ability to access storage sequentially or variably (e.g., tape storage versus random access memory). Encoded data may be stored as persistent or volatile memory (e.g., hard disk versus RAM), it may be mutable or read-only (e.g., hard disk versus WORM CD/DVD "write once, read many”). Without storage ability, a computer becomes a signal processing device (e.g., a CD player). Storage makes up one of the core components of a computer system along with the central processing unit, as defined in the von Neumann model which has been in use since the 1940s. Computer data storage, distinct from electronic data storage, requires a computer system to read and manipulate the encoded data. A brief introduction would define it as any device which requires electrical power to record information. Published in Organdi, a peer-reviewed journal of culture, creation, and critique - Issue 9, 2007ĭefining electronic data storage, as the elaborations in this section will indicate, is no trivial task. ![]() Or how technological improvements challenge mass media with individual mediaīy Lev Lafayette.
