Describe the role of social media sites in digital communication technology?

Describe the role of social media sites in digital communication technology? Social media sites provides many types of ways to share and allow to send different types of data such as:- text data through file of text document or direct message text to the chat box directly to the user by typing, the audio clip can be recorded to send the file or direct voice calling system allows to connect with the user when the user is online. Similarly, video data can be shared to the user in the form of a file and directly connected in the form of video call or video chatting. The image file can be used to share the information object which is still object information including text data depending on the creators. The social media sites provide the services of connecting users through the data communication system using the different types of option such as:- chatting using text messages, audio clipping sends methods, recorded current video through the camera or direct video call or chat option, voi...

How to create a student mark sheet database in according to the object oriented database management system model?

Mark sheet is a real world object and there are so many details in the mark sheet. What kind of attributes and classes are related to the mark sheet object in the perspective of object oriented database management system model?

Student mark sheet database

How to create a student mark sheet database in according to the object oriented database management system model?

There are basically divided into two categories of mark sheet database. One is the database of student and second is the database of school system. The mark sheet is a combination of both type of database. In this post here is the explanation of database of school system.

Database of School System

It is class of Student Mark sheet database in according to the object database. It is connected with strong line connection as shows in the image. It is provided by the school system to the student mark sheet database. There are some fields or attributes in the class of database of school system. It holds different types of data type in the different types of fields.

Here is the heirarchical reference of database of school system following below here:


Here is the heirarchical reference of database of school system following below here:

Board Name

It is name of the board examination in the mark sheet database. It holds character data type. It is common attribute in the mark sheet database.

{Board name = Character type data}

Types of student result detail

The ‘types of student result detail’ depends on the board examination and their decision. Such as number based mark sheet database or grade based mark sheet database.

{Types of Student result detail = Character type data}

Roll Number for student

It is unique attribute in the mark sheet for student verification which is provided by the board examination control system. It holds numerical data type.

{Roll number for student = Numerical type data}

Mark sheet number

It is a strong attribute of database in the mark sheet which is also provided by the control examination of board. It holds numerical data type.

{Mark sheet Number = Numerical type data}

Signatures of all type

These signatures are depends on the image type data which is considered by the human not a robot.

{Signature of Principal = Image type data}

{Stamp of Principal Signature = Image type data}

{Signature of control examination = Image type data}

The Date of submission

It is a numerical data type attribute in the mark sheet which is most important to verify the submission date of mark sheet.

{Data of Submission = Numerical type data}

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. 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 ...

What are the three main purpose of an operating system?

What are the three main purpose of an operating system? There are three main purpose of an operating system. 1. The first main purpose is User interface between hardware and users. 2. The second main purpose is to operate the internal parts of the computer properly and systematically using binary code system in the form of 0 and 1. 3. The third main purpose is to provide an environment for development of an application software and program to uses the hardware resources of the computer and connected to the computer parts which provides output to the user, the output from application software is very useful for users. Interface between user and hardware device  The operating system uses all types of interface such as command line interface, batch command interface and Graphical User Interface to interact with users to hardware peripheral devices through the monitor screen. Monitor has a big role making interface between hardware and users. Monitor visualization of all types ...
