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.
Physical address and logical address?
A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.
Which OSI layer addresses data messages translates logical addresses into actual physical addresses and routes data to addresses on the networks?
Network layer
Which layer translates between physical and logical addresses?
Data Link Layer
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 paging and how is it done?
Paging is a memory management scheme in which physical memory is divided into fixed-size blocks called pages, and logical memory is divided into blocks of the same size called frames. The operating system uses a page table to map logical addresses to physical addresses during memory access. When a process requests data that is not in physical memory, a page fault occurs, leading to the system retrieving the required page from secondary storage into physical memory.
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.
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...........
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.
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
