In the 8086/8088 the physical address and logical address have the same importance, because they both relate to the address of the operand. It is true that the offset (logical) address is added to the segment address to determine the physical address, but the limitations of the architecture of the processor forces programmers to consider both.
If you are talking about a virtual environment, however, such as in the 80286 or higher, then the logical address is more important than the physical address, because the logical address is the address of the operand, while the physical address is (somewhat) arbitrarily assigned by the operating system.
What else can I help you with?
Is it true that if you create logical subdirectories you can more easily locate individual files?
Yes, it is true.
Is use case model a logical or physical?
A use case model is a logical model.Each actor on a use case diagram represents a roleA role is a set of related activities executed by one or more people in the organzation. A role is not a specific user, although in some organizations a single person may execute a function leading you to believe that the function is user specific. This is simply a case of a role that is only executed by a single person.A use case essentially outlines a process, for example withdraw money is a use case that exists for an ATM. Withdraw money is execucted by the role customer. Withdraw money can be executed many times.Both actors and use cases are abstract and therefore are not physical models.
What is structured programming in java?
It is a subset of procedural programing that enforces a logical structure on the program being written to make it more efficient and easier to understand and modify.
What is a relationship between engineering and other sciences?
well,the difference is not that big since Engineers and Scientists are all technologists. The main difference is that in Engineering, we deal more with structures and more physical works (or applications) while we do no much of physical works in Science,we instead do just more theory and non-physical practicals.. I don't know if that helps.
Difference between primary and extended partitions?
Primary Partitions are logical areas on Coputer storage devices that have direct reference in Master Boot Record. (Due to limitation imposed by MBR only four primary partitions can be created). While Extended partitions refer to logical areas created out of need for more than four Partitions.
In paged system Can the logical address space b larger than physical address space?
Yes. This is the fundamental premise of paged or virtual memory - that you can have more logical memory than physical memory.
Differentiate physical and logical addresses?
logical address and physical addressIn a system, there are two types of addresses: logical and physical. Another name for logical address is IP address and it is set by your Internet service provider (ISP) or your router. If you have a router then you have a LAN, which sets a logical address for your computer. Your router will have an logical address set by your ISP.The physical address is also called the MAC address and it is generated by the manufacturer. (but only to a given extent)Because a MAC address is assigned (by the FCC) to a company to use for a range of products.For example:01:23:45:00:00:00 - 01:23:45:FF:FF:FFWould be their "range" of MAC addresses. They use a coding called Hex which is not to far off from what you know which is base-10 (0-9).Instead hex uses (0-F). 0123456789ABCDEFA = 10, B = 11, etc.Read more: What_is_the_difference_between_logical_address_and_physical_addresses
What is difference between logical file and physical file?
* Physical file (PF) contains the data and have only one record format. Logical file (LF) is a view of the physical file which does not contain any data may be based on one physical file or more then one physical file. Logical file can have more then one record format. Logical can be non join or join logical file. Performance becomes better if you use the logical file in the program.
What are the advantages of using logical address?
One might be able to get more appropriate traffic to their website or email address if the words that make it up describe it in some way, or are logical.
What is the difference between a physical address and a mailing address?
Real memory uses Physical addresses.These are the members that the memory chips react to on the bus. Virtual addresses are the logical addresses that nrefer to a process' address space. Thus, a machine with a 16-bit word can generate virtual addresses upto 64K, regardless of whether the machine has more or less memory than 64 KB
Why logical data independence is more difficult than physical data independence?
Logical data independence is considered more difficult than physical data independence because it involves changes to the conceptual schema and external schema, which are more closely tied to the way data is organized and viewed in the application. Physical data independence, on the other hand, deals with changes to the internal schema, which is more abstract and can be modified with less impact on the overall system.
Is it best to use your physical address or PO Box for a home-based business?
It depends on which is more important to you:If your privacy or your and your family's safety, use a PO Box addressIf your prospects' and clients' trust, use your physical address
Is it harder to achieve logical data independence or physical data independence?
It is generally considered more difficult to achieve logical data independence compared to physical data independence. Logical data independence involves separating the conceptual structure of the data from the physical storage aspects, which can be complex depending on the database design. Physical data independence primarily deals with shielding the application from changes in the storage structure, which is usually more straightforward to achieve.
What is the Logical drive and physical drive?
* Physical file (PF) contains the data and have only one record format. Logical file (LF) is a view of the physical file which does not contain any data may be based on one physical file or more then one physical file. Logical file can have more then one record format. Logical can be non join or join logical file. Performance becomes better if you use the logical file in the program.
Which of the OSI layers translates the MAC address into a physical address?
The MAC sublayer is part of Layer 2 - Data Link Layer - but it is more correct to say that the MAC address is the physical address.
How many logical drives can be created on a fat drive?
When you partition a hard drive into two or more partitions (storage areas) those extra drives are called logical drives. So you can have 2 or 3 or more logical drives on one physical hard drive. It varies.
Why is human resources are more important than physical resources?
It is more important because without it, there would never be physical resources.
