Discuss the disadvantages of web applications based on centralized systems? Centralized models based web application provides many types of disadvantages for the client user. Web applications use centralized models that make high security models to protect the database which can be lost due to any physical damage or logical level attack by cyber criminals or malicious files. If the user has a long distance to access out of range of the server then it can be slow to access the web application data available to the internet service. Web applications based on centralized systems have several disadvantages that can impact performance, reliability, and security. One major drawback is the single point of failure—if the central server experiences downtime, crashes, or is attacked, the entire application can become inaccessible to users. This lack of redundancy makes the system vulnerable to outages and disruptions. Additionally, centralized systems often struggle with scalability, as the cent...

Describes the consequences of a centralized model with a distributed system using a hybrid approach? The centralized model enhanced their processing power to the user as increasing growth of the user to use the service improved performance for the user to quickly use the option and data processing on the website. Distributed system provides the high performance of data access from the website. If the centralized database is original then the distributed system provides the copy of the file to access the database file for the user. A hybrid approach that combines a centralized model with a distributed system can offer both advantages and challenges. In such a setup, the centralized component manages critical control and decision-making functions, while the distributed elements handle data processing and execution across various nodes. This can improve efficiency and scalability, as tasks are shared among multiple systems, reducing the load on the central unit. However, it also introduce...

How do you understand about the DCN in network technology? DCN is a Data communication network technology that provides the data that can be shared to each other who are connected in the network model and internet connection between many users or private chat. The user can share the files which include the information depending on the text data, image data, audio and video database files can be shared to each other in the DCN. The DCN allows the devices that can be used to perform a task on the network model and shares the task if the specific hardware is not working currently on the network model then the user can use other same connected devices to perform the tasks. Data Communication and Networking (DCN) refers to the study and practice of transmitting data and establishing connections between different devices over a network. It involves understanding how data is sent, received, and managed through various communication channels like cables, fiber optics, or wireless systems. In D...

Discuss the monitoring system in the storage area network model? Storage area network model uses the application software that provides the monitoring system for the user to provide management system, devices manager section, query performance for specific websites and other types of function that storage area network maintained from the application software. Storage area networks provide the same file which is stored in multiple copies to make data reliable for the user which the user wants to search and find the file which is the same information cannot be removed if any storage device has been damaged the copies of same file can be provided from the other connected storage devices. The user can find easily from monitoring the same files using the application working between the storage area network model. In a Storage Area Network (SAN) model, the monitoring system plays a crucial role in ensuring the smooth operation, performance, and security of the network. It continuously observ...

Explain some points on the data access control in web application software? The web application software needs to protect data which is connected to the user account on the web applications software such as:- name, city, email address, private posts and videos and images etc. The user needs to protect their database files into the web applications used through the authentication system on the user account before accessing it; they need to verify some queries on the layer that is known as the security layer. The security included the authentication process to verify the detail which the user enters in the web application software such as:- password and name with unique special characters in the security model in the web application then verify if they are correct information and matches from the security saved database which is already setup and saved by the user who has an account on the web application software. Data access control in web application software is a critical aspect of s...
