Question: Why IP Address Is Called Logical Address?

What is difference between physical and logical address?

The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program whereas the physical address is a location that exists in the memory unit..

How do I find a logical address?

we know that logical address spaces is = total no of bits required to represent total no of pages + bits required to map page offset . Hence total bits required = 3 (because total no of pages is 8 and to represent you need three bits) + 10 (page offset is 1024 so you need 10 bits) = 13 bits all total.

What is effective address?

The effective address is the location of an operand of the instruction, since the operand is the data to be accessed. Immediate instructions use their operand to hold the data needed to complete the instruction.

What is logical memory?

Virtual (or logical) memory allows programs to use a very large range of memory or storage addresses for stored data. • The computing system maps the programmer’s virtual addresses to real hardware storage addresses.

Is logical address same as IP address?

Every network device has two types of addresses, one called the logical address — in most cases this is the IP address — and the other one being the physical address — also known as the MAC address. … The IP address is an address bound to the network device, i.e., computer, via software.

Why do we need logical address in networking?

The logical address is a 32-bit IP address that is not embedded in the network card but it is assigned to it for the purpose of routing between networks. This type of address operates at Layer 3 (network) of the OSI Model.

How is logical address converted to physical address?

The translation between logical addresses and physical addresses is specified by a table structure. A logical address requested by the execution unit is translated by the memory management unit into a physical address which is then used to access a location in physical memory.

What happens if 2 devices have the same MAC address?

If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. … Duplicate MAC Addresses separated by one or more routers is not a problem since the two devices won’t see each other and will use the router to communicate.

What is another name for a physical address?

A physical address is also known as a binary address or a real address.

What is meant by logical address?

In computing, a logical address is the address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program. A logical address may be different from the physical address due to the operation of an address translator or mapping function.

What is the use of logical address?

Logical address is used to reference to access the physical memory location. A logical address is generated so that a user program never directly access the physical memory and the process donot occupies memory which is acquired by another process thus corrupting that process.

Is MAC address physical or logical?

MAC Address is a physical address. IP Address is a logical address.

What is a physical address example?

A physical address is a real street address that can be used as a personal or business mailing address. … Unlike a PO Box, a physical address can receive unrestricted mail and parcels from carriers other than USPS, such as UPS, FedEx, DHL, and Amazon.
