A memory address or the location of a memory cell in the main memory is referred to as a physical address in computing. It is used to access data by both hardware and software. Software, on the other hand, does not use physical addresses directly; instead, it uses a virtual address to access memory.
A physical address indicates the location of memory, but a logical address indicates the address of the CPU, i.e. the address is generated by the central processor unit. There can only be one physical address per device. They are unchangeable because they are consistent. A single device can have many logical addresses.
The entire physical address, which is 20 bits long, is constructed using 16-bit segment and offset registers. A segment register's content is also known as segment address, while an offset register's content is also known as offset address.
The USPS does not assign addresses or designate addresses as either residential or commercial. Your local government office can provide you with information on land use and zoning. The local government entity that has control over the area where the streets are located creates street addresses.
Your physical address is your street address, city, state, and zip code. A logical address is a virtual address that is used for routing information on the internet. Here's how to convert your physical address to its logical equivalent.
