The owner of a memory block is a 16-bit word. It is set to zero to indicate a free block. A non-zero value is normally the PID (process identifier) of the owner, that is, the address of the PSP of the owning process. This is important when a process terminates, because DOS automatically frees all memory blocks that the process owned. Note that DOS performs no validity checks on the owner; any process can free or resize any block, regardless of who owns it, and the MCB owner need not be a valid PID.

Modern technologies like search engines and social media reshape the information environment in response to user behavior [cinelli_echo_2021, leung_narrow_2025]. As algorithms optimize for relevance and engagement, they construct environments that reflect and reinforce users’ existing search strategies. For instance, when seeking information online, people will often use search terms that narrowly reflect their hypothesis [leung_narrow_2025, e.g., “caffeine health risks (benefits)” instead of “caffeine health effects”;]. Search engines retrieve results that match these queries, effectively validating the user’s biased hypothesis with a skewed sample of resources. As a result, users’ existing beliefs are reinforced. Critically, people do not recognize their queries as biased or spontaneously correct for this.
