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 (motherboard, expansion cards, including the graphics card), it remains only about 2.8 to 3.3 GB of RAM addressable following configuration PC.
Answer Processes access virtual memory space, not physical memory. Applications never access RAM directly but only through the memory management interface of the processor. Depending 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.
Max. memory address space= 216 X 2 bytes = 128 Kbytes
A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.
The amount of memory (RAM) Google SketchUp or any other design tool out there is using, is relative to the complexity of the model you are working on. Ideally, the more the better, but that is also Operating system (OS) limited: - Sketchup is a 32bit application. - Windows 32bit cannot address (use) more than 3GB or RAM (3.2GB, but w/e). Having more than 3GB (or 4GB, still you cannot use all of it) in a 32bit Windows Machine is pointless. Macs work a bit differently, so even 32bit OS can address more than that. - Individual Applications are not allowed by 32bit Windows to use address more than 2GB of RAM. - Windows 64bit, by default, run 32bit Applications (like Sketchup) with the same 2GB limitation, only that can be "patched", so each can use up to 4GB (64bit apps do not have such limiations, but SU is not one of them yet). You can follow the guide in this site to do so: http://maketecheasier.com/increase-memory-limit-for-32-bit-applications-in-windows-64-bit-os/2011/08/13
The 8086/8088 can address a maximum of 220, or 1,048,576, or 1 MB of memory.
You can use either a 32bit or 64bit operating system (OS) for 4GB of RAM. 4GB of memory is the limit a 32bit OS can handle, this includes any memory that your graphics card has, so your computer may recognise only 3.5GB of RAM if you have a 512MB GPU. You will need a 64bit os that will use all of the ram.
32 bit processor can access 4294967296 bit memory adderss.
In turbo C pointer maximum refers up to 1MB of memory, wheras in GCC pointer refers up to 4 gb of memory.
The 8085 microprocessor is an 8-bit processor with a 16-bit address bus. This means it can access a maximum of 64 KB (2^16) of memory. The 8085 can address memory locations from 0000H to FFFFH, totaling 64 KB of memory space. This limitation is due to the 16-bit address bus, which can only address up to 64 KB of memory.
A 14 bit address can specify 214 or 16,384 different locations.
Address space refers to how much memory you could potentially talk to so for instance a 32bit processor has a 32 bit addres space i.e. 2^32 = 2 x 2 x 2 ..... 32 times which equals 4294967296 - this is 4Gigabytes. The physical memory is how much memory you have installed so this could be anything up to 4GB. Any memory above 4GB would no be able to be used by the processor.
The Intel 8085 microprocessor uses an 8-bit data bus and a 16-bit address bus. It can address 64 KB of memory, with each memory location capable of storing a byte. Therefore, the maximum positive number that can be represented in an 8-bit register is 255 (2^8 - 1), while in a 16-bit address space, the maximum is 65,535 (2^16 - 1) when considering the entire memory range.
