WebDec 7, 2011 · Addressability. Addressability is the way in which the computer identifies different memory locations. The size (width) of the address bus determines how many memory locations can be addressed. For example , a 1 bit address bus can access 2 memory locations; a 2 bit address bus can access 4 memory locations and a 3 bit … WebThe 64-bit address space also includes the virtual line at the 16-megabyte address; additionally, it includes a second virtual line called the bar that marks the 2-gigabyte address. The bar separates storage below the 2-gigabyte address, called below the bar, from storage above the 2-gigabyte address, called above the bar .

WebThe original MVS™ (pre zOS) architecture defined storage addresses as 24 bits in length, which allowed an allocation to each user an address space of 16 MB. Later, the addressability of the architecture was extended to 31 bits, which increased the addressability of virtual storage, and the size of the address space, from 16 MB to 2 GB. WebSep 13, 2014 · It depends on how you address the data. If you use 32 bits to address each bit, you can address 2 32 bits or 4Gb = 512MB. If you address bytes like most current architectures it will give you 4GB.. But if you address much larger blocks you will need less bits to address 4GB. For example if you address each 512-byte block (2 9 bytes) you …
