#block.computer_memory_unit  (computer science) a sector or group of sectors that function as the smallest data unit permitted; "since blocks are often defined as a single sector, the terms `block' and `sector' are sometimes used interchangeably"
  subtype:  #bad_block  (computer science) a block (usually one sector) that cannot reliably hold data
  part:  #sector.computer_memory_unit
  supertype:  #computer_memory_unit  a unit for measuring computer memory
     supertype:  #unit_of_measurement__unit  any division of quantity accepted as a standard of measurement or exchange; "the dollar is the United States unit of currency"; "a unit of wheat is a bushel"; "change per unit volume"
        supertype:  pm#unit_of_measure   Any kind of unit of measure, metre, dollar, kilogram, etc. 
           supertype:  pm#attribute_or_quality_or_measure  e.g., mass, mass unit, 1 kg, frequency, [2-3] hz, color, blue, speed, 1 m/s
              supertype:  pm#non_spatial_object__nonspatialobject  abstraction or description content/medium/container (a description medium that has some spatial feature is both instance of sumo#object and pm#non_spatial_object
                 supertype:  pm#entity  something that can be "involved" in a situation
                    supertype:  pm#thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
                 supertype:  cyc#intangible  The collection of things that are not physical -- are not made of, or encoded in, matter. Every cyc#Collection is a cyc#intangible (even if its instances are tangible), and so are some cyc#individuals.  Caution: do not confuse `tangibility' with `perceivability' -- humans can perceive light even though it's intangible--at least in a sense.
                    supertype:  cyc#partially_intangible__partiallyintangible  The collection of things that either are wholly intangible (see cyc#Intangible) or have at least one intangible (i.e. immaterial) part (see cyc#intangibleParts). This includes intangible individuals, such as instances of cyc#Number-General  or cyc#Agreement, as well as non-individuals (all of which are intangible), i.e. instances of cyc#SetOrCollection.  It also includes things that have both tangible and intangible components (see cyc#CompositeTangibleAndIntangibleObject),  such as a printed copy of a newspaper (as its information content is intangible) or a person (as her mental states are intangible).
                       supertype:  pm#thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
              supertype:  pm#thing_that_can_be_seen_as_a_relation  usable as relation type
                 supertype:  pm#thing_playing_some_role  category to classify things according to roles/viewpoints; classification under this category is application-dependant
                    supertype:  pm#thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
              supertype:  pm#individual__particular___supertype_of_1st_order_types  all individuals (for concepts or relations) are implicitely or explicitely instance of that type
                 supertype:  pm#thing__something___T__t___3D_or_4D_thing_or_anything_else  any category (type or individual) is instance of this type; any type is also a subtype of this type
        supertype:  #definite_quantity  a specific measure of amount
           supertype:  #measure__quantity__amount__quantum  how much there is of something that you can measure
              supertype:  pm#attribute_or_quality_or_measure  e.g., mass, mass unit, 1 kg, frequency, [2-3] hz, color, blue, speed, 1 m/s
        supertype:  #size  the physical magnitude of something (how big it is); "a wolf is about the size of a large dog"
           supertype:  #magnitude  the property of relative size or extent; "they tried to predict the magnitude of the explosion"
              supertype:  #property.attribute  a basic or essential attribute shared by all members of a class; "a study of the physical properties of atomic particles"
                 supertype:  #attribute  an abstraction belonging to or characteristic of an entity
                    supertype:  pm#attribute_or_quality_or_measure  e.g., mass, mass unit, 1 kg, frequency, [2-3] hz, color, blue, speed, 1 m/s
     supertype:  #capacity.indefinite_quantity  (computer science) the amount of information (in bytes) that can be stored on a disk drive; "the capacity of a hard disk drive is usually expressed in megabytes"
        supertype:  #indefinite_quantity  an estimated quantity
           supertype:  #measure__quantity__amount__quantum  how much there is of something that you can measure
