What is the purpose of data communication? Explain the data communication system.

What is the purpose of data communication? Explain the data communication system. The purpose of data communication is to share the data and information between two or more users through the medium of communication known as the physical layer to connect the users to each other. Users who can connect to the data communication model need to connect with the computer system, network device, cable and application software for making a model of data communication system. The data transmission in digital data communication is a term of transmission in three different types of mode : simplex mode of data transmission, half duplex mode of data transmission and full duplex mode of data transmission. The data communication model is mostly used for major communication systems in the digital term such as TCP/IP and OSI model for digital data communication systems. Where the TCP is used for providing the connection of four types of layer which is used to make data transmissions between two or more ...

What is data transmission and its types?

What is data transmission and its types? Data transmission is a type of data sharing system to provide the protocol followed by the user on the hardware resources for how to send the data to another user on the data transmission model in the digital data communication system. The digital data communication system contains the data transmission system which means the data is transmitting to the particular and targeted address on the connection of two users or more users depending on the connectivity of the digital data communication system. The data transmission is basically three types of method to send the data to the particular address from the sender to receivers according to the physical layer of the network model. Data transmission mode or method such as simplex mode to transmit the data, half duplex data transmission mode and full duplex mode of data transmission between many users or two users. The simplex mode of data transmission:- The simplex mode of transmission of data is o...

What are the reasons for the termination of the application software development?

What are the reasons for the termination of the application software development? The termination of the application software is a closing program of the application software development of the software development company. The termination process is applied on the application software project to stop their development that have some reason to close the overall project on the application software. The termination process is applied when the application software project cannot providing any type of profit then the company decides the application software project need to be close due to further more reasons such as losses of application software in the marketplace, not used in the future, customer company cancel their dealership with the application software development company to close their project due to more additional reason of their personal experience of company which doesn't completely shared to the software development company. If the customer requests to close the project o...

What are the reasons for the Project scheduling of the application software development?

What are the reasons for the Project scheduling of the application software development? The project scheduling is to develop the project model for managing all types of parts of the application software such as system design model, database model, coding and data flow chart and model, security model for protection of database of user and application. The project scheduling model included the development time, cost estimates, risk management etc. Topics related to the different types of parts of application software such as system design model, coding section, security model and database model. Project model is used to provide to the different types of departments which are related to the system design model development department, programming department, security model development department, database department etc. For development of the application software each employee follows and the implementation the rules and develops the application software in the discipline manners. Introd...

What are the reasons for the resource requirements of application software development?

What are the reasons for the resource requirements of application software development? Resources is used to connect the application software to provide by the input value to the application software for processing the input data through the input hardware resource or device, the output data provided by the output hardware resource or device from the application software and the storage device or resource is used for the store the data of the application software, the file which is a product of the application software on the memory of the storage device of the computer system. Resources of the application software is necessary because the application software is only operated by the resources and control the resources to provide the solution in the form of data depends on the types of output hardware resource such as printer provide the hardcopy of image and text data and audio data provided by the speaker output resource of the computer system controlled by the application software. ...
