Discuss the input and output values in the database on the application software? The input values come from the input resources such as:- a computer has different types of input resources: keyboard, mouse, scanner, camera, microphone etc. these are generally used on the computer system. The output values are provided through the output resources such as:- speaker provides audio data or sound and the printer provides hardcopy to the user, and the monitor output resource provides display form of text, image and video or motions and still graphics animation to the user. So, the application software processed the input data that comes from the input resource to process it and provide the output or to store into the storage device. For example:- If the application software is used to process the BCR data comes from the BAR code reader then the application is used to process input values from the BCR to store into the database file or it can be prepared for a hardcopy form a bill to the cust...

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

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.

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. Without memory, computers are not be able to store data, instruction etc. The memory is an essential part of a computer system. It is require by the computer system to store information. Memory can be divided into the following two categories types: i) Primary or Main memory ii) Secondary Memory or Permanent memory In this figure I'll show the classification of the memory of computer system peripheral and architecture of organisations Primary Memory or Main memory:- i) Primary memory is the memory which is fastest memory of the computer. ii) It is a small but relatively fast storage unit that stores data and instruction which are used by the CPU (central processing unit). iii) This type or category of a memory is the main memory of the computer.It is a temporary memory and also we ...

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...
