" Computers themselves were initially engines of prediction and prognostication..., not recollection and storage; they only became so with the advent of the so-called von Neumann model and the somewhat later addition of random access disk memory, which enabled reliable real-time, nonsequential access to large reserves of information." (Kirschenbaum 5)
It seems Kirschenbaum is asserting how technology, and the advancement of storage, impacted our ability to process, store, and manage large systems of data, which in turn created a larger and more complex database. He also goes on to make note of the accessablity of memory and storage (Ipod/flashdrive etc.), and how this transformation has created a more open and transferable network.
