Computer science terms and defs
User-defined data type: a data type based on an existing data type or
other data types that have been defined by a programmer.
Non-composite date type: a data type that does not reference to another
data type.
Enum data types: a non-composite data type defined by a given list
of all possible values that has an implied order.
Pointer data type: non-composite, uses memory address of where data
is stored.
Serial file organization: records are stored one after the other in order
that they were recorded.
Sequential file organization: records of data are stored in a given order.
Random/Direct file organization: records are stored in file at any free
location, the location is calculated using a hashing algorithm on their key
field of the record.
Hashing algos: a mathematical formula used to perform calculation on
the key field to return the location of the record.
File access: Method used to physically find a record in a file.
Sequential access: records are searched one after another in a
sequence.
Direct access: a record can be found in a file, without having to go
through other records.
Mantissa: fractional part of a floating point
