INTERNAL CHIP ORGANIZATION

-
A memory chip is an electronic component in which a program, data or both can be stored. The program / data are stored in the memory chip as a series of numbers - zeros and ones (=bits).  A bit can be either a zero or a one.  Sixteen bits are a "word", eight bits are a "byte" and four bits are a "nibble". ORGANIZATION OF A MEMORY CHIP For the 8 bit memory chips (the most common type) the bits are put together in a byte (= 8 bits) and stored under an "address". The bytes can be accessed at this address and then the eight bits of the accessed address are output on its eight data ports. EPROM memory chips (27 / 27C...) EPROM stands for Erasable Programmable Read Only Memory. "Erasable" means that the data on it can be removed. "Programmable" means that a program or data can be programmed (burned) into this chip. "Read Only Memory" means that this type of memory can be read out but not programmed in ...

OBJECT ORIENTED DATABASES:

-
An object database (also object-oriented database management system )  is a  database management system  in which information is represented in the form of  objects  as used in  object-oriented programming . An object may be defined as any entity in the real world tha has some characterstics An object has two components namely state(value) and behaviour(operations) Objects exist in two forms given below: Transient objects: Those which exist only during program execution Persistent Objects:Those which exist permenantly The objects may have an object structure of arbitrary comlexity in order to contain all necessary information to describe the object The internal structure of an object in object oriented programming language inlude specification of instance variables Object Oriented Database (OODB) provides all the facilities associated with object oriented paradigm ie  Object-oriented database management systems (OODBMS...
