Memory Organization: Characteristics
| Q. Enumerate important characteristics that a computer
memory organization system should possess. (Jan 01, June 01,

Ans. An effective computer memory organization system
should possess:
- It should be possible to add and integrate new knowledge
in memory as needed without concern for limitations in size.
- Any organizational scheme chosen should facilitate the
remembering process. Thus, it should be possible to locate
any stored item of knowledge efficiently from its content
alone.
- The addition of more knowledge to memory should have no
adverse effects on the accessibility of items already stored
there. Thus, the search time should not increase appreciably
with the amount of information stored.
- The organization scheme should facilitate the recognition
of similar items of knowledge. This essential for reasoning
and learning functions. It suggests that existing knowledge
be used to determine the location and manner in which new
knowledge is integrated into memory.
- The organization should facilitate the process of consolidating
recurrent incidents or episodes and forgetting" knowledge
when it is no longer valid or no longer needed.

Frame problem
| Q. Briefly write about 'Frame Problem' in context of 'Knowledge
Organization and Management'. (Dec. 99, June 00, Jan. 01, Dec.
01, Dec. 02, June 03) |
|
Ans. This is the problem of knowing what changes have
and have not taken place following some action. Some changes
are the direct result of an action and the other are secondary
or side effects. For example, if a robot is cleaning the floors
in a house, the location of the floor sweeper changes with
the robot even though this not explicitly stated. Other objects
not attached to the robot remain in their original places.
The actual changes must somehow be reflected in memory, a
feat that requires some ability to infer. Effective memory
organization and management methods must take into account
effects caused by the frame problem.
