A physical network diagram depicts the network topology with the physical aspects like ports, cables, racks, and more. A logical network diagram, on the other hand, shows the “invisible” elements and connections flowing through the physical objects on the network.

What is a logical topology?
A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Using network equipment such as routers and switches, the logical topology of a network can be dynamically maintained and reconfigured.
Is star topology a physical or logical topology?
Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.
What are types of logical topology?
Logical Topologies. The two logical topologies are broadcast (also known as bus) and sequential (also known as ring).
What are examples of logical topology?
Logical network topology examples include twisted pair Ethernet, which is categorized as a logical bus topology, and token ring, which is categorized as a logical ring topology.
What is the difference between a physical design and a logical design?
A physical design focuses on specific solutions explaining how they are assembled or configured. A logical design focuses on satisfying the design factors, including risks, requirements, constraints, and assumptions.
What are the 5 types of topologies?
- Bus Topology. Bus topology is the kind of network topology where every node, i.e. every device on the network, is connected to a solo main cable line.
- Ring Topology.
- Star Topology.
- Mesh Topology.
- Tree Topology.
- Hybrid Topology.
What is the physical or logical arrangement of a network called?
The physical or logical arrangement of network is called topology.
What are the 8 types of topology?
- P2P Topology.
- Bus Topology.
- Ring Topology.
- Star Topology.
- Tree Topology.
- Mesh Topology.
- Hybrid Topology.
What is a logical network?
A logical network is a portion of a physical network that connects two or more logical network interfaces or devices. A logical network interface or device is the software entity that is known by an operating system.
Why can single physical topology support multiple logical topologies?
Logical is how data is transferred in the network; physical is the physical connections in the network. Why can a single physical topology support multiple logical topologies? A physical topology can support many logical topologies because of how data is transferred in the physical topology.
What is the relationship between logical and physical design?
The logical design is more conceptual and abstract than the physical design. In the logical design, you look at the logical relationships among the objects. In the physical design, you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.
What is the difference between physical and logical data?
Physical data models are used to visualize the physical structure of databases and data files. Logical data models are used to visualize data entities, attributes, keys, and relationships.
What is difference between physical and logical address?
Physical Address is the actual address of the data inside the memory. The logical address is a virtual address and the program needs physical memory for its execution. The user never deals with the Physical Address.
Is Ethernet a logical topology?
The Ethernet operates on a logical bus topology. All the components on the network share the same medium and are detected based on the MAC address. Due to the shared component, the multiple components transfer at the time of data collisions.
Where is logical topology used?
The logical topology is used to create a path to send signals across the network. It uses the network protocols which define the path for transferring packets. The most common example of network protocols is the ethernet protocol.
What are most common logical topologies?
Bus logical topology is the most common logical solution for the bus, star, or star-wired bus physical topologies. This logics can be defined, as data from one device travels to all devices in this network. Ethernet is based on this logical topology.
What is meant by physical topology?
Physical topology refers to the interconnected structure of a local area network (LAN). The method employed to connect the physical devices on the network with the cables, and the type of cabling used, all constitute the physical topology.
What is the relationship between logical and physical models quizlet?
Distinguish between logical process models and physical process models. Logical process models describe processes without suggesting how they are constructed. Physical process models provide information that is needed to ultimately build the system.
What is logical and physical design in system analysis?
Logical design maps the conceptual model to a particular DBMS model or a representation of the software. Physical design is concerned with technical specifications. Hardware and network issued are considered along with data storage structures for files or databases.
What are the two components of a logical data model?
Therefore, logical data modeling combines the two most important components of application development: business requirements and quality data structure.
Which one is not a topology?
Topologies include bus topology, ring topology, star topology, mesh topology, and hybrid topology. Peer to Peer isn’t one of them.
Which topology is best and why?
The best cabled network topology for large businesses is the star topology. This is because it is easier to control from a central console as the management software just needs to communicate with the switch to get full traffic management features.
How many types of topologies are there?
There are two kinds of computer network topologies: physical and logical. Physical topology: This is one of the types of network topology that provides the layout of computer cables and other network devices. Logical topology: This topology provides information about the physical design of a network.
Which topology has highest reliability?
Mesh topology: In this, each device has a dedicated point to point link to every other device. Dedicated means that a link carries traffic only between two devices it connects. It is the most reliable topology.
