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...

If Mark sheet is the real world object then what are the classes, attributes and their values in according to the object oriented database management system model? – Part3

How to create mark sheet database of student is a real world object in according to the object oriented database management system model? – Part3

Connection between Student mark sheet database, Database of student and mark sheet detail of student

If Mark sheet is the real world object then what are the classes, attributes and their values in according to the object oriented database management system model? – Part3

Student mark sheet database is oriented based object and it is divided into two classes which one is the database of student is connected to the strong line. The database of student is connected to the mark sheet detail of student which is sub class of the Class ‘Database of Student’.

The Mark Sheet detail of student

There are seven fields or attribute of the sub class of ‘mark sheet detail of student’. These fields hold numerical data type data in their value of fields.

English is an attribute that their value is val1. It is a subject of the student.

{English = Numerical data type}

Hindi is an attribute that their value is val2. It is a subject of the student.

{Hindi = Numerical Data type}

Mathematics is an attribute that their value is val3. It is a subject of the student.

{Mathematics = Numerical Data type}

Science is an attribute that their value is val4. It is a subject of the student.

{Science = Numerical Data type}

SST is an attribute that their value is val5. It is a subject of the student.

{SST = Numerical Data type}

Total is an attribute that has function to calculate the values of all subjects.

{Total = Numerical Data type}

If the Total = [val1+val2+val3+…] = sum of the values.

Percent is the attribute that their value is in the float value. Float is the data type which takes also the decimal values. The sign of float is [%] which is also called modulus function.

{Percentage = Float Data type}

If the Percentage = sum of values % Number of all subjects = values in float.

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 ...
