Question: What Is Physical And Logical Network?

What is physical connection of network?

Wireless networks are easy to overlook as physical network connections.

Without network-level authentication on the wireless LAN, any two devices with wireless antennae, regardless of whether they have logical connection to the “active” wireless network in question, should be considered “physically” connected..

What is a logical process?

Logical Process Modeling is the representation of a business process, detailing all the activities in the process from gathering the initial data to reaching the desired outcome. These are the. kinds of activities described in a logical process model: Gathering the data to be acted upon.

What are the 4 types of networks?

Types of NetworksPersonal area network, or PAN.Local area network, or LAN.Metropolitan area network, or MAN.Wide area network, or WAN.

What is a physical topology?

Physical network topology is the placement of the various components of a network and the different connectors usually represent the physical network cables, and the nodes represents usually the physical network devices (like switches).

What is a logical server?

A logical server allows one or more servers of a multiplex to be grouped together to serve one or more applications or users.

What are the important components of network architecture?

Business Network Administration – Basic ComponentsRouters. Routers are devices on the network which is responsible for forwarding data from one device to another. … Switches. … Network hubs. … Wireless access points. … Network Cables. … Network Server. … Network Interface Cards (NIC)

What is the difference between logical and physical network diagram?

Logical network diagrams focus in on how traffic flows across the network, IP addresses, admin domains, how domains are routed, control points, and so on. … A physical network diagram will, ideally, show the network topology exactly as it is: with all of the devices and the connections between them.

What is a logical network diagram?

Logical network diagrams A logical network diagram describes the way information flows through a network. Therefore, logical network diagrams typically show subnets (including VLAN IDs, masks, and addresses), network devices like routers and firewalls, and routing protocols.

How are logical diagrams used?

A logical DFD can capture current and necessary activities required for a process. A new logical DFD models a new set of activities and functions. … Then we specify system events that require a response, and event DFDs are drawn to depict how each event is handled. These event DFDs can then be merged in a system diagram.

What is a logical architecture?

Logical architecture describes how a solution works in terms of function and logical information. From an abstraction level viewpoint, it represents a middle ground, sitting between the Conceptual and Physical architectures. Unlike these, however, logical architecture is quite broad in scope.

What is logical diagram?

logic diagram (plural logic diagrams) A diagram in the field of logic. Any non-spatial, abstract diagram. Any schematic display of the logical relationships of project activities. A graphical representation of a program using formal logic.

What is the difference between physical and logical?

The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program whereas the physical address is a location that exists in the memory unit.

What is computer logical?

(1) Refers to a user’s view of the way data or systems are organized. The opposite of logical is physical, which refers to the real organization of a system. For example, a logical description of a file is that it is a collection of data stored together.

What is a logical network topology?

Logical topology is the arrangement of devices on a computer network and how they communicate with one another. … The logical topology defines how nodes in a network communicate across its physical topology. The logical topology can be considered isomorphic to the physical topology, as vice versa.
