What is an extension of the physical address?

EXTENSION (P can only be done on systems that are 32 -bit, use X86 processors and have more than 4 gigabytes (4 GB) memory. In this way, the computer will have memory for applications and storage and do not create memory as it would usually. (OS). burned down or crashed.

Extension of physical ADRAces can only be used in 32 -bit systems if the memory is 4 GB or higher. In other systems over 32 bits, P Mode may be made to use more than 4 GB of memory, so smaller memory systems will not have access to this function, because nothing would change if allowed.

The total amount of memory that can be used depends on the OS. The minimum is 4 GB, but more advanced systems have access to more than 100 GB of memory. Server computers usually use this because such a large amount of memory is required for daily tasks. In domestic computers, the minimum amount will be sufficient for most tasks.

When the physical purchase of the address is allowed, all memory is converted to system memory, so it can be used for applications. This means that programs are less likely to crawl and multiple applications can be used at a time without a disadvantage. By the only potential disadvantage of using p
