As file systems grow in size, ensuring that data is safely stored becomes more and more difficult. Historically, le system backup strategies have focused on logical backup where files are written in their entirety to the backup media. An alternative is physical backup where the disk blocks that...
Summary Logical vs Physical DFD Note that the Context Diagram didNOTrecord the movement of merchandise, but rather the information flow surrounding the underlying business processes. Let's summarize their differences: A DFD that shows the movement of information is called alogicalDFD. ...
Consider a file system on a disk that has both logical and physical block sizes of 512 bytes. Assume that the information about each file is already in memory. For each of the three allocation strategies (contiguous, linked, and indexed), answer these questions: a. How is the logical-to-...

As your database grows to the size of a few gigabytes, backing it up through physical backups is more ideal than through logical backups. As explainedhere, over time, performing logical backups in large databases could lead to degraded performance for other queries. Given the long run time ...
Data flow diagrams generally fall into one of two categories, logical or physical data flow diagrams, where each has different functions. If you work in a field that uses DFDs, such as IT, system analysis or business analysis, it can be useful to understand what a logical flow diagram is ...
Maps a logical view to a physical view. This method is called before CreateEditorInstance to allow us to map logical views to physical ones. C++ 复制 public: virtual int MapLogicalView(Guid % logicalView, [Runtime::InteropServices::Out] System::String ^ % viewName); Parameters logicalView...
Hardware partitioning: Also known as physical partitioning, it is the process of dividing a computer's hardware resources, such as memory and processing power, into separate, independent sections that different applications or operating systems can use....
