What are logical modules?

Logic modules are programmable controllers which allow machines to perform processes without human intervention. Therefore, logic modules can be considered as intelligent controllers. Logic modules are mainly used in the industry where complex installations operate with many different automated processes.

What is the difference between physical and logical data?

The main difference between Logical and Physical Data Model is that Logical data models help to define the data elements and their relationships, while the physical data models help to design the actual database based on the requirements gathered during the logical data modelling.

What is difference between logical and physical data independence?

The physical data independence is basically used to separate conceptual levels from the internal/physical levels….Difference between Physical and Logical Data Independence :

Physical Data Independence	Logical Data Independence
It is easy to retrieve.	It is difficult to retrieve because the data is mainly dependent on the logical structure of data.

What is the difference between a physical and logical 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 logic in Eurorack?

Binary or Boolean logic is a way of combining gate signals (on or off voltages) to create new outputs. Each section of a logic module typically includes 1 to 3 inputs, with 2 being the most common.

What is the difference between physical and logical standby database?

The logical standby database is a database that does not have the schema structure exactly similar to the source database. In contrast, a physical standby database is a database that replicates the exact contents of its primary database across the Oracle Net Network layer.

What is the difference between a logical and physical data flow diagram?

A logical DFD focuses on the business and business activities, while a physical DFD looks at how a system is implemented. It provides a solid basis for the physical DFD, which depicts how the data system will work, such as the hardware, software, paper files and people involved.

What’s the difference between logical and physical topology?

A logical topology is how devices appear connected to the user. A physical topology is how they are actually interconnected with wires and cables.

What is the difference between physical and logical data independence which one do you think is harder to achieve and why?

Logical data independence is more difficult to achieve than physical data independence, since application programs are heavily dependent on the logical structure of the data that they access.
