What is Object Oriented Database Management System (OODBMS)? Explain briefly?

The OODBMS explain by the following points.

It is Object based Database system.
It is oriented by Oops concept which is stands for Object oriented programming system.
In this database able to create classes, object and data structure etc.
It also follows hierarchical database model concept in the pictorial representation.
In the database model parent classes and child classes are available in the data model.
In this model the solid lines are represents classes and sub classes link together.
In this model the dotted lines are represents attributes of classes.
This database concept follows the polymorphism and inheritance.

Discuss the role played by the various components of the CPU

Q Discuss the roles played by the various components of CPU? The CPU is the brain of the computer system. All major calculations, manipulations and comparisons are made by the CPU. The CPU is also responsible for activating and controlling the operations performed by all other units of the computer system. The major components of the CPU are: a) Arithmetic Logic Unit (A.L.U.) b) Control Unit (CU) c) Primary Memory Arithmetic Logic Unit (A.L.U.): What is ALU Arithmetic logic Unit? ALU is a part of the CPU. It is a part to calculate the logical term in the CPU where the term refers to an operation of logical type. It also calculates the arithmetic terms in the CPU where the term refers to an operation of arithmetic type. It is used to direct access through the processor controller. The ALU connected to the input and output peripheral system through the bus with the different types of bus. Such as control bus, data bus etc. ALU is a part of the CPU that can calculate the input...

About the memory and its Classification of the computer Memory

What are the memories in the reference of computer system? What is Computer Memory?:- The memory is the essential for the computer to store the data, instruction and information.
