Moca

MOCA is an acronym that can refer to several distinct things depending on context. One common usage is the Montreal Cognitive Assessment (MoCA), a brief cognitive screening tool designed to detect mild cognitive impairment and early signs of dementia. The test comprises a 30-point exam that typically takes about 10 minutes to complete. Scoring ranges from 0 to 30, with scores of 26 or below often interpreted as indicating possible cognitive impairment; adjustments for education and language can affect interpretation. MoCA was developed in Montreal by Ziad Nasreddine and has since been translated into many languages and used in clinical and research settings worldwide.

Another major usage of the acronym is Museum of Contemporary Art (MOCA), which refers to several contemporary art museums that use this branding. Notable examples include the Museum of Contemporary Art in Los Angeles and institutions such as MOCA North Miami and MOCA Taipei. These museums specialize in contemporary visual art and typically organize rotating exhibitions, commissions, education programs, and related public events. The exact organizational structure, collections, and programming vary by location.

MOCA also stands for Multimedia over Coax Alliance, a technology standard for high-speed data networking over existing coaxial cable within homes. MOCA enables devices such as set-top boxes, routers, and media players to communicate through a wired home network without new cabling. The standard has evolved through multiple versions to improve throughput and reliability and is commonly used by cable operators and consumer electronics manufacturers to distribute entertainment and data services.
