the network administrator uses the OSI model to troubleshoot network problem by verifying functionality of each layer, in many cases, troubleshooting the network problem requires the network administrator to isolate at what layer the network problem occurs.
network administrators often describe networking problems by layer number, for example, a physical link problem is described as a layer 1 problem; a router problem is a layer 3.
This bring layer approachdue to this network troubleshooting is so easy , - Determine the symptoms, Isolate the problem., Fix the problem.
In that way it's much easier to control network, maintenance, and control user computers.
The best way to prepare a questionnaire is isolate the problem you are trying to resolve first. Once you have the problem, then you can model a questionnaire around solving the problem.
I depends on the manufacturer and model. 192.168.0.0 or 192.168.0.1 are fairly common, but there can be many others.
The firewall blocks it. Almost all router have telnet port blocked because it's considered dangerous.
In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).In the OSI reference model, that would be layer 3 (network).

what is the architecture of database network
This is a peer-to-peer network, where all devices in the workgroup have equal status. In this model there is no central management of the network (or any network management at all).

A peer to peer network.
1. Relational Model : Newer database model; Network Model - Older database model 2. The network model structures data as a tree of records with each record can have multiple parent and child records, forming a lattice structure. The basic data structure of the relational model is the table, where information about a particular entity (say, an employee) is represented in columns and rows 3.The relational model has strong mathematical foundation with set theory and predicate logic. Network Model has no strong mathematical background. 4. Relational model is the most flexible of the database models. Network model is not very flexible. 5. Relational model has widespead use. Network model has limited use.
