What is the maximum memory that can be accessed by 16 address lines?

Using 16 bits, you can write 65536 addresses (from 0 to 65535, that’s 65536 different addresses), and address 65536 bytes. 65536 bytes is 64kB. In computer science, b is bit, B is byte. The byte is the smallest amount of memory you can address.

What is the maximum memory capacity?

For example, most 32-bit CPUs can address only up to 4 gigabytes (GB) of memory. The reason the maximum capacity in a 64-bit computer is limitless for all intents and purposes (see chart below) is that 64-bit hardware manipulates (calculates, compares and copies) 64 bits, or 8 bytes, of data at a time.

What is the maximum memory address space that the microprocessor can access directly if a 16-bit memory module is interfaced with the microprocessor?

The microprocessor can access 216=65536 memory addresses, regardless of the size of data held at each memory address. If each memory address holds one byte (8 bits) of data then the total memory size that can be addressed directly is 216 bytes, which is 26 KiB=64 KiB.

What is 16-bit operating system?

16-bit is a computer hardware device or software program capable of transferring 16 bits of data at a time. For example, early computer processors (e.g., 8088 and 80286) were 16-bit processors, meaning they were capable of working with 16-bit binary numbers (decimal number up to 65,535).

What’s the memory limit for 32 bit Windows?

For more information, see What is 4GT. Limits on physical memory for 32-bit platforms also depend on the Physical Address Extension (PAE), which allows 32-bit Windows systems to use more than 4 GB of physical memory. The following table specifies the limits on memory and address space for supported releases of Windows.

How much memory can you use with 12 bits?

Size of memory = 8 * 2 12 bits = 2 12 bytes = 2 2 Kilo Bytes (210 Bytes = 1 KB) = 4 KB

What’s the memory limit for a x86 server?

Any X64 Windows or X86 Server release can. X86 client versions with PAE enabled do have a usable 37-bit (128 GB) physical address space. The limit that these versions impose is the highest permitted physical RAM address, not the size of the IO space. That means PAE-aware drivers can actually use physical space above 4 GB if they want.

How much RAM can you use with 12 bits address bus?

If you have a byte-addressable memory (i.e every byte in the memory has an address) and an address bus of size 12 (i.e 12 wires in the address bus or 12 bits in the Memory Address Register). How much maximum RAM can you support ? If there are just 2 bits in the address, then there can only be 4 addresses, viz.
