How logical address is converted to physical address and who is responsible for it?

How logical address is converted to physical address and who is responsible for it?

Memory Management Unit(MMU) is a hardware component responsible for translating a logical address to a physical address.

How will you convert logical address to physical address segmented memory management?

Convert logical address to linear address The segment register is a 16-bit register. The 0th and 1st bits control the privilege level of the segment to be accessed. The second bit indicates whether to search for the address in GDT or LDT. The upper 13 bits are used as an index value, totaling 8192 indexes.

How a logical address is mapped to physical address in virtual concept?

Since a logical address does not physically exists it is also known as a virtual address. This address is used as a reference by the CPU to access the actual physical memory location. There is a hardware device called Memory-Management Unit is used for mapping logical address to its corresponding physical address.

How does the MMU translate logical address to a physical address?

Terminology: the MMU performs address translation by mapping the logical addresses (also called virtual addresses) to physical addresses.

1. Virtual addresses are used by programs. Pointers will be to virtual addresses; the linker will also map symbolic names to virtual addresses.
2. Physical addresses are indexes into RAM.

What is differences between logical and physical addresses?

The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program. On the other hand, the physical address is a location that exists in the memory unit. The set of all logical addresses generated by CPU for a program is called Logical Address Space.

Why IP address is called logical address?

IP Address works at the network layer of OSI model (actually the IP layer of TCP/IP model). This is a logical address (and not the embedded hardware address) which is assigned by the Network administrator or Internet service provider. Hence IP address may change each time you connect with the Internet.

What is logical physical and port address?

Logical Address: is used at network layer. It is IP address that is generated while transmission of data over a network. Port address : is used at transport layer. In Transport layer there is process to process delivery for that it requires port address.It transfers data from client to server.

How do I get a US physical address?
