What is a function of the distribution layer in the hierarchical design model?
provide connectivity between smaller local networks
2 Explain why navigation is simple in Relational Data Model than in Hierarchical?
Navigation in the Relational Data Model is simpler than in the Hierarchical Data Model due to the relational structure of tables linked by common keys. In the Relational Data Model, data is organized into tables with rows and columns, allowing for easy querying and retrieval of information using SQL queries. On the other hand, in the Hierarchical Data Model, data is organized in a tree-like structure with parent-child relationships, making navigation more complex and requiring traversal of multiple levels to access specific data points.
Which layer of the hierarchical design model provides a means of connecting devices to the network and controlling which devices are allowed to communicate on the network?
distribution
Is a ip address flat or hierarchical?
MAC addresses are flat.

How is data organized in hierarchical data model?
The hierarchical model is a restricted type of network model. Again, data is represented as collections of records and relationships are represented by sets. However, the hierarchical model allows a node to have only one parent. A hierarchical model can be represented as a tree graph, with records appearing as nodes (also called segments) and sets as edges.
Advantages of hierarchical database model?
optical illusion
Who established the first hierarchical model of management?
church
Which layer of the hierarchical three-layer design model combines traffic from multiple IDFs?
which layer of the hierarchical three-layer design model combines traffic from multiples IDFs? core layer
What are the three benefits of hierarchical network model?
Reduced content for bandwidth Increased fault tolerance of the network Simplification of management and troubleshooting
Difference between network model and hierarchical model and relational model?
The relational model is a model in which data is isolated by object and foreign keys to those objects which is organized in tables with multiple columns or attributes. The hierarchical model is a model in which the data is organized in a tree structure that allows repeating information using parent/child relationships.
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.
Advantages of flat data model?
two main early navigational data models were the hierarchical model and the CODASYL model (network model)
Which company has developed the hierarchical model?
IBM International Business Machines
What are the benefits of a hierarchical data model and network data model?
In network model of database , all data is related to each other through a link. By a link we mean that it is an association between precisely two records/data . In hierarchical model records are organized as trees rather than arbitrary graphs.
What are the differences between the Hierarchical model and the Network models?
The Hierarchical model organizes data in a tree-like structure with parent-child relationships, allowing each child to have only one parent, which creates a clear, but rigid, hierarchy. In contrast, the Network model allows for more complex relationships by enabling each record to have multiple parent and child records, facilitating a more flexible and interconnected data structure. This flexibility in the Network model can accommodate many-to-many relationships, whereas the Hierarchical model is limited to one-to-many relationships. Consequently, while the Hierarchical model can be simpler to navigate, the Network model offers greater versatility in representing complex data relationships.
