Let’s take an example of the purpose of a digital data communication system

What is the purpose of a digital data communication system?


Digital database communication system is a communication based on the digitization which includes the digital transmission of the data with signals forms of 1 or 0 based techniques to detect and identify the digital signals. The data can be transferred to the user if the user is connected to the network to sender user on the network model or internet services.


What is the purpose of a digital data communication system?


Digital communication generally uses the communication models: TCP/IP, OSI model, Peer to peer connection, PAN etc. that are used to provide the communication and the data sharing system to connect to each other computer using their request based method to accept the request by the user on the data communication system.

Let’s takes an example on the digital data communication system following below here:-

If the user is try to send the file which has a size of 30 mb (megabyte) to the connected user on the data communication model in the network model then how much can take the latency to send to the user where the network model supports 1mbps of speed to share the data to each other between the network model.

The file size = 30mb (megabyte)

The speed support in network model = 1mbps (megabit per second)

Calculation of the latency of file transfer:-

Time of data transfer speed = file size ( in megabyte ) / network support speed 

= 30/1

= 30 seconds

In the example the file can take 30 seconds to transfer the completed file to the user who receives the file.

This is a basic example of the data transfer timing or latency based numerical and an example to describe how the network model works during the data transfer to each other.


Introduction to the computer related topic of computer application and system technology topic is following below here:


What is the purpose of a digital data communication system?


Let’s discuss this topic following above the related topic of computer application and system technology and explanation following below here:


What is the purpose of a digital data communication system?

There are some points on the computer system and data communication system related to the topic of “What is the purpose of a digital data communication system?” following below here:


What is the purpose of a digital data communication system?

  • User connects with their communication device
  • User can share the data to each other when they are connected in the same network
  • The network device is main part of the network model and communication model
  • The user can secure the account on the digital data communication system


Let’s discuss the points listed above about the computer system and digital data communication system related to the topic of “What is the purpose of a digital data communication system?” explanation following below here:


User connects with their communication device

Users connect with their communication device through the network device and the computer system or smartphone which is a complete communication device.


The user can call the user through their number of contacts that provide the call request to receive the call from the caller from the smartphone device.


The computer is able to send the data through the single data cable which is a direct connection to the computer if the user connects only through the data cable directly connected to another computer.


The user can also increase the computer connection through the network device to enhance the network model and share the data to each other.


The resources are used to give an input instruction to the computer that sends the data to the other computer by the users and make a data communication system by sharing files and data transfer to each other.


User can share the data to each other when they are connected in the same network


Users can share the data to each other when they are connected in the same network model because it is necessary to connect the computer to the network model.


The network model is a type of system where many users can share the data to each other based on the “one to many” or “many to many” or “many to one” or “one to one” etc.


The network device such as:- the switch connects many computer systems that provide the ports connection to share the data depending on their IP address.


The server network device provides the website interface which is used for processing and execution of the program on the website and also supports the database processing at the backend system.


The network device is main part of the network model and communication model


The network device is a main device in the network model to provide the connection for the computers system and the resource connection.


The network model is used to perform the task through the resource of the input device into the application software or provide the output data to the client user or admin users.


The network device used to connect with their IP address verification and registration to connect after verifying the correct IP address through the connection of the data cable.


The data transfer speed depends on the data cable and the network device to send the data to the computer system through the data cable based on the TCP model or OSI model on the network device in the network model.


The user can secure the account on the digital data communication system


The user secures their account which has been created in the network application used in the network model to provide the security for protection of the saved digital data of the user as a personal or official or sensitive database.


The security layer basically included the username and password verification system based on the relational database model which processes only the text data.


Some users applied and want to use the object based verification on the security layer for protection through the biometric verification identity on the security model such as:- finger verification, eye scanned verification, voice recognition etc.


The unknown user cannot access any user which has been applied to the security layer to protect the data as a personal or official database in the network model and digital data communication system.
