Which OSI layer addresses data messages translates logical addresses into actual physical address and routes data to addresses on the network?
Network layer
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.
Are network layer address physical or logical?
Layer 3 network addresses are logical addresses and can be easily changed by software.
How can one calculate the physical address from a given logical address?
To calculate the physical address from a logical address, you can use the base address and offset. Add the base address to the offset to get the physical address. This process is commonly used in computer systems to translate logical addresses to physical addresses for memory access.

Differences between physical addressing and logical addressing?
In computer architectures, a logical address is the address at which a memory location appears to reside from the perspective of an executing application program. This may be different from the physical address due to the operation of a memory management unit (MMU) between the CPU and the memory bus. Physical memory may be mapped to different logical addresses for various purposes. For example, the same physical memory may appear at two logical addresses and if accessed by the program at one address, data will pass through the processor cache whereas if it is accessed at the other address, it will bypass the cache.
What is the role of the operating system play in the translation of logical addresses to physical addresses?
The operating system plays a crucial role in managing the translation of logical addresses to physical addresses through a process called memory management. It uses a combination of hardware (like the Memory Management Unit) and software techniques (such as paging and segmentation) to map logical addresses generated by programs to actual physical addresses in RAM. This abstraction allows for efficient memory use, isolation between processes, and protection against unauthorized access. Ultimately, the operating system ensures that each program operates within its allocated memory space while maintaining overall system stability.
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.
Is a MAC address logical?
A MAC address is not considered logical; it is a physical address. It is a unique identifier assigned to network interfaces for communications on a local network segment and is hardcoded into the network hardware. Unlike logical addresses, such as IP addresses, which can change based on the network configuration, MAC addresses remain constant for a device's network interface.
What identifies both the logical host and the logical network addresses?
The IP protocol identifies both the logical host as well as the logical network addresses...........
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
