Correct spelling for the English word "PAE" is [pˈiː], [pˈiː], [p_ˈiː] (IPA phonetic alphabet).
PAE stands for Physical Address Extension. It is a computer technology that allows a computer system to exceed the traditional limit of 4 gigabytes (GB) of memory addressing. PAE extends the physical address space from 32 bits to 36 bits or more, allowing access to a much larger amount of memory.
In traditional computer systems, the 32-bit memory addressing can only support a maximum of 4 GB of RAM. However, with the advancement of technology and the need for more memory in modern computing, PAE was developed to overcome this limitation. By increasing the number of bits in the memory addressing, PAE enables a computer system to access and utilize more memory, typically up to 64 GB or even more.
PAE is commonly used in server systems and high-performance computing environments where large amounts of memory are necessary for running complex applications or handling extensive data processing tasks. It allows these systems to maximize their memory capabilities and operate more efficiently.
Implementing PAE requires both hardware and software support. The computer's processor must support PAE, and the operating system must have a PAE-enabled kernel to take advantage of the extended memory addressing. Failure to meet these requirements will result in the system being limited to the traditional 32-bit memory addressing.
Overall, PAE is a technology that extends the capabilities of computer systems by allowing them to utilize more memory, enhancing their performance and enabling them to handle more demanding tasks effectively.
