difference between logical and physical model . (subject name: systems analysis and design)
Operating Systems Name two differences between logical and physical addresses. Why are page sizes always powers of 2? Consider a logical address space of 64 pages of 1,024 words each, mapped onto a physical memory of 32 frames. a. How many bits are there in the logical address? b. How many bits are there in the physical address?
What is the difference between a probability derived from the analytic view (logical analysis), the Relative Frequency view (sampling from distributions with known characteristics), and the Subjective (feeling) view. Name some situations in which each view could be useful.
Explain the difference between physical access and logical access to memory of any storage device (e.g. the HDD)?
An important concept in the design and analysis of secure systems is the security model because it incorporates the security policy that should be enforced in the system. Here is a question to start off the discussions: Which model deals only with confidentiality and what are its significant tenets?
Class, What is the difference between a data entity (data model) and an external entity (process model)? Tables are made up of rows and columns. What do the rows represent? What do the columns represent? What is the difference between the logical ERD and the physical ERD? How can you translate entities from the CDFD? (Analyze the data flows.)
We apply a database model (e.g., the relational model) to our database design at which point in the lifecycle? a. As part of the conceptual -> logical design transition b. As part of the logical - > physical design transition c. As part of the physical -> implementation transition d. As part of the requirements definition -> conceptual design transition
Subject Name: Object Oriented Analysis and Design Explain the following diagram (Minimum 1 page answer required) Dynamic Modeling Structure in Motion
Differentiate between logical and Procedural representation of Knowledge? Subject is AI
How does system analysis vary from system design? Name different model-driven methods.
23) A Logical model used to gather information about an existing system A) comes only after a physical model of the existing system is created. B) describes how a system actually works, rather than how it should work. C) illustrates how a system functions by describing the flow of documents and computer processes D) illustrates what is being done, regardless of how that flow is actually accomplished. 24) A prototype A) is expensive to create and is therefore only created...
