What is meant by effective address in microprocessor?
Effective address is the final address generated by offsetting and indexing which is sent to the virtual translation logic. It is the address of the operand in the virtual address space of the process, but not necessarily the address of the operand in the physical address space of the computer. In the 8085, efffective/virtual address is the same as physical address, because there is no virtual addressing logic in the 8085. In the 8086/8088, effective/virtual address is the same as physical address, but only in real mode. For example, in the 8086/8088, if the EBX register contains 1000000H, then the instruction MOV EAX,[EBX+1234H] has an effective address of 10001234H.
How virtual address is translated into physical address?
MMU-memory management unit
How does the virtual address to physical address mapping work in computer systems?
In computer systems, the virtual address to physical address mapping works through a process called address translation. The operating system manages this mapping by using a page table, which stores the correspondence between virtual addresses used by programs and their corresponding physical memory locations. When a program accesses a virtual address, the operating system translates it to the corresponding physical address to retrieve the data stored in memory. This allows programs to efficiently access and manipulate data without needing to know the physical location of the memory.
How physical address is generated?
A physical address is generated through a process called address translation, which typically involves the use of a memory management unit (MMU). When a program accesses a virtual address, the MMU translates this virtual address into a physical address by using a page table that maps virtual pages to physical frames in memory. This process allows the operating system to efficiently manage memory and provide isolation between processes. Ultimately, the physical address corresponds to a specific location in the computer's RAM where data is stored.
Do I need a physical office in Malaysia?
Not necessary. Physical address is not mandatory when you have a valid virtual address that comes under the jurisdiction of Malaysian government. Virtual office concepts getting the attention nowadays.
What is the difference between virtual logical and physical address spaces?
The concept of a logical address space is simply involved the process of mapping the Logical addresses to their Physical Addresses . Logical addresses are generated by the CPU; also referred to as virtual addresses.while Physical Address is the actual address of the data stored on the physical device and mapped by MMU.
Which address is more important the physical address or the logical address?
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.
Why you need memory physical address and memory logical address?
Physical Address refers to Storage location on Physical Memory wheres Logical Addressing is used by Memory Managing Programs to refers addresses from Physical Memory and Virtual Memory.
How do you calculate paging address?
To calculate a paging address, you need to divide the virtual address into two parts: the page number and the offset. The page number is obtained by dividing the virtual address by the page size, while the offset is found by taking the modulus of the virtual address with the page size. The page table is then used to translate the page number into a corresponding physical frame number, which is combined with the offset to form the final physical address.
What identifies the virtual machine and is part of the machine and physical network address?
The virtual machine is identified by its unique MAC (Media Access Control) address, which is assigned to its virtual network interface card (vNIC). This MAC address is essential for communication within the physical network, allowing the virtual machine to send and receive data. Additionally, the virtual machine has an IP (Internet Protocol) address, which is assigned within the network and enables it to connect to other devices over the internet or local network. Together, these addresses help manage and route network traffic to and from the virtual machine.
What does physical address mean?
The physical address is the final address that is presented to the bus, at the pins of the microprocessor chip, to form the address of the desired item in memory.In the 8085, physical and effective addresses are one and the same.In the 8086/8088, the physical address is the effective address plus 16 times one of the segment registers.In higher level processors, such as the 80386 and beyond, the physical address is formed by lookup of the effective address in a page table to convert from virtual/effective address to physical, or linear, address.The effective/virtual address is the address generated by the instruction and the programmer, without regard to any underlying addressing scheme. This is the address used when considering the "programming model", in "user mode".
How do you obtain a Physical address before owning property in area?
You can rent a mailbox at a local post office or obtain a virtual mailbox service. Virtual mailbox services provide a physical address that can receive and manage your mail remotely. Alternatively, you can use a co-working space or a business center to obtain a physical address for business purposes.
