What is the maximum amount of memory any single process on Windows can address?
What is the maximum amount of memory any single process on Windows can address and is this different from the maximum virtual memory for the system?
Answer Processes access virtual memory space, not physical memory. Applications never access RAM directly but only through the memory management interface of the processor. D…epending on which version of Windows you are using, and how the program was compiled there is a different maximum ammount of addressable memory. All 32 bit processes on 32bit Windows have a 4GB virtual address space. The upper 2GB is common to all processes and is used by the system. The lower 2GB is private to each process and is inaccessable to all others. Unless the program was compiled as large address aware, in which case it will have 3GB of private address space. For 32bit processes on 64bit Windows, each process has 2GB private address space, unless compiled large address aware in which case it has 4GB private address space. For 64bit processes on 64bit windows each process has 8TB of private address space whilst compiled as large address aware. The 2GB address space limit remains for programs not compiled as large address aware. This is completely independent of the size of RAM or the pagefile. The system maps physical memory into this virtual address space according to both need and availability. At any given time the data in virtual memory space might be stored in RAM, on disk, or both. All of this is totally transparent to all applications. Frequently accessed data will be kept in RAM with the remainder left on disk.
If an address bus for a given computer has 16 lines what is the maximum amount of memory it can access?
If an address bus for a given computer has 16 lines, what is the maximum amount of memory it can access?
Not possible to answer the question. You need to provide more details. To be precise, the maximum addressable memory is limited by the memory controller, not the CPU, and ca…n be further limited by the operating system.
32-bit system can address: 2 to the power of 32 = 4.3 Giga different addresses, corresponding to 4.3 GB of RAM as it needs to manage other stuff than the RAM (mother…board, expansion cards, including the graphics card), it remains only about 2.8 to 3.3 GB of RAM addressable following configuration PC.
It depends on the processor and the operating system. In the 8086/8088, with a 20 bit address bus, you can address 1,048,576 bytes of memory.In the 8085, with a 16 bit addres…s bus, you can address 65,536 bytes of memory.In the IA-32 architecture (80386 and higher in 32 bit mode), you can address 4,294,967,296 bytes of memory (physical) minus about 805,306,368 bytes of memory for overhead (operating system).In the IA-64 architecture (80686 running in 64 bit mode on 64 bit Windows) you can address 206,158,430,208 bytes of memory.
The max is 3 gigabytes. The actual amount depends on how much of workout you are giving the computer . . . 2 gigs should cover most Office programs, and 3 gigs is not quite en…ough for certain of the graphics programs.
192 GB max RAM on 64 bit processor or 4 GB on a 32-bit
It requires 192 GB of system memory. I am assuming that you are getting this question from the Windows & Configuration textbook by Craig Zacker, as I found that exact question… in there. You can find the answer on page 15 in table 1-4. Hope that helps!
In Windows XP
192 Gigabytes is the maximum.
In Windows 7
Windows 7 home premium 64-bit can support up to 16GB of RAM
