- What does it mean to have a subnet mask 32? - Super User
and also check out subnet calculators the 32 is the CIDR (shorthand) and refers to how many 1's are in the subnet mask For 32 that is 255 255 255 255 or 11111111 11111111 11111111 1111111 that means you can only have one ip address, on your network before needing a gateway router to get outside that network with 32 it's just you
- 32-bit vs. 64-bit systems - Super User
What 32-bit vs 64-bit does not imply: On x86 systems, 32-bit vs 64-bit directly refers to the size of pointers That's all It does not refer to the size of the C int type That's decided by the particular compiler implementation, and most of the popular compilers choose 32-bit int on 64-bit systems
- How to resolve You cannot install the 32 64 bit version of Microsoft . . .
2 If you have 32-bit version of Office, you need to remove the 64 bit version Click to Run Do the simialr things if you have 64-bit version of Office To uninstall Office 16 Click-to-Run Extensibility Component 64-bit Registration, please try the steps below:
- 64 bit - How can I open the 32-bit ODBC Data Source Administrator in . . .
I want to add 32-bit data sources There seems to be no obvious way to see existing instances of these or create new ones How can I open the 32-bit "ODBC Data Source Administrator" window in Wind
- Memory limits in 16, 32 and 64 bit systems - Super User
The theoretical memory limits in 16, 32 and 64 bit machines are as follows The fundamental flaw here is the notion that the "bit width" of the processor, which is usually the size of the machine's general-purpose registers, is necessarily the same as the width of RAM addresses
- Why can a 64-bit OS take full advantage of a 4GB RAM but a 32-bit OS . . .
A 32-bit process running on that OS still uses 32-bit addresses, so can still address only 2 32 different memory locations, which are bytes in most modern architectures, so in theory they can access at most 4GB of RAM In practice only a part of that belongs to the process, because the kernel reserves the remaining address space for themselves
- x86 vs x64 - Why is 32-bit called x86? - Super User
Presumably the x86 was called so because the machines used 80386 and 80486 processors Is that correct? Is that the right way to refer to 32-bit and 64-bit machines?
- Can a 32-bit OS machine use up all 8GB RAM - Super User
What I understand about 32-bit OS is, the address is expressed in 32 bits, so at most the OS could use 2 32 = 4G memory space -- I assume the unit is bytes, so 4GB Does this mean if any machine with a 32-bit OS (be it Windows or Unix) has more than 4GB total of RAM + page file on hard disk, for example 8GB RAM and 20GB page file, its memory will never be "used up"? By "used up" I mean that
