What is network model in DBMS?
network model is a collection data in which records are physically linked through linked lists .A DBMS is said to be a Network DBMS if the relationships among data in the database are of type many-to-many. The relationships among many-to-many appears in the form of a network. Thus the structure of a network database is extremely complicated because of these many-to-many relationships in which one record can be used as a key of the entire database. A network database is structured in the form of a graph that is also a data structure .
Difference between hierarchical and Network data module?
The hierarchical data model organizes data in a tree-like structure with a single parent for each child record. On the other hand, the network data model allows for multiple parent-child relationships, creating a more flexible and complex network of interconnected records. In the hierarchical model, relationships are one-to-many, while in the network model, relationships can be many-to-many.
Is it true that Many networks use a network server to manage the data flowing through the network devices and the resources on a network?
Yes, it's true that many networks utilize a network server to manage data flow and resources. The network server acts as a central point for data storage, resource allocation, and communication between devices, ensuring efficient management and security. By handling tasks such as authentication, file sharing, and network services, the server helps optimize the overall performance of the network.

What are the difference between hierarchical database and network database?
Hierarchical databases organize data in a tree-like structure with parent-child relationships and a strict one-to-many hierarchy, while network databases use a more flexible model with many-to-many relationships through pointers or links between records. Hierarchical databases are faster for accessing data along predefined paths, while network databases allow for more complex data relationships but can be more complex to manage.
What is network ddl?
Network DDL (Data Definition Language) refers to a set of SQL commands used to define and manage the structure of a network database. It includes operations for creating, altering, and deleting database objects such as tables, indexes, and relationships within a network model. Unlike traditional relational databases, network databases use a more flexible structure that allows for complex many-to-many relationships, making DDL in this context essential for establishing those connections. Overall, Network DDL helps define how data is stored and accessed in network database systems.
How do you tell how many gb of downloads and uploads I've used?
To check your data usage for downloads and uploads, you can access your device's settings or network settings, where most operating systems provide a data usage summary. For Windows, go to Settings > Network & Internet > Data usage. On macOS, you can use Activity Monitor under the Network tab. For mobile devices, check under Settings > Cellular or Settings > Network & Internet. Additionally, many internet service providers offer usage tracking through their websites or apps.
How much does a star network cost?
