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..
What is the purpose 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.
What is meant by physical address?
A physical address, sometimes referred to as a street address, is used to describe where a place is geographically located. It often pertains to a geographic location under the jurisdiction of an administrative area or region that has some government function.
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.
Who generates logical address?
Logical address is address generated by CPU during execution whereas Physical Address refers to location in memory unit(the one that is loaded into memory). Note that user deals with only logical address(Virtual address). The logical address undergoes translation by the MMU or address translation unit in particular.
Is IP address logical or physical?
Logical vs. An IP address is a logical address that is assigned by software residing in a server or router (see DHCP). The physical address is built into the hardware (see MAC address).
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.
Where is logical memory stored?
Logical memory is stored in physical memory, and in various places on your hard drive. The usual places are a swap file (stores data from logical memory that has been modified but not used for a while), and memory mapped files.
What is another name for physical address?
In computing, a physical address (also real address, or binary address), is a memory address that is represented in the form of a binary number on the address bus circuitry in order to enable the data bus to access a particular storage cell of main memory, or a register of memory mapped I/O device.
What is the difference between a physical address and a virtual address?
Physical addresses refer to hardware addresses of physical memory. Virtual addresses refer to the virtual store viewed by the process. … only a portion of the address space that processes do use is loaded into physical memory at a time.
What is the most common logical address used in networking today?
Network Logical addressing Every network device has a physical address called a MAC address, which is assigned to the device at the factory. When you buy a network interface card to install into a computer, the MAC address of that card is fixed and can’t be changed.
How do you write a physical address?
How to write an addressWrite the recipient’s name on the first line.Write the street address or post office box number on the second line.Write the city, state, and ZIP code on the third.
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.
Is IP address same as MAC address?
The main difference between MAC and IP address is that, MAC Address is used to ensure the physical address of computer. It uniquely identifies the devices on a network. While IP address are used to uniquely identifies the connection of network with that device take part in a network.
What is logical and physical 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.
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.
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 logical address with example?
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.
How many bits are in logical address?
1 Answer. logical address space contains 32 pages and to represent 32 pages we need 5 bits (2^5=32) and each page contains 2048 words therefore the offset or “d” parameter can be represented by 11 bits (2^11=2048). So total number of bits to represent logical address = 5+11=16 bits.
What is a logical host?
A logical host is a logical server environment that acts as the execution environment when you run JP1 in a cluster system. Running JP1 on a logical host typically involves linking with cluster software in the cluster system, and performing failover on a logical host basis.
What is my virtual address?
Virtual Payment Address also referred as VPA is something like an email-ID, which is given to an individual using the Unified Payment Interface (UPI) service to send or receive money. With UPI, fund transfers can be initiated without IFSC code or bank account number.
