Debian Explanation

tasksel shows all available tasks and allows to user to select ones
to install

computer science Theory Drop

A  task is  an execution  path through  address space.[1]  In other
words, a set of program instructions that are loaded in memory. The
address registers have been loaded  with the initial address of the
program. At the next clock  cycle, the CPU will start execution, in
accord with the program. The sense  is that some part of 'a plan is
being accomplished'. As long as the program remains in this part of
the   address  space,   the  task   can  continue,   in  principle,
indefinitely, unless the program instructions contain a halt, exit,
or return.
