How does 32-bit address 4GB if 2^32 bits = 4 Billion bits not Bytes?

Essentially, how does 4Gb turn into 4GB? If the memory is addressing Bytes, should not the possibilities be 2 (32/8) ? 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 can address 4GB with 23 bits. FAT16 uses 16 bits to address (maximum) 64KB clusters and therefore can address a maximum 4GB volume. The same

Call Activity method from adapter

Is it possible to call method that is defined in Activity from ListAdapter ? (I want to make a Button in list's row and when this button is clicked, it should perform the method, that is defined in corresponding Activity. I tried to set onClickListener in my ListAdapter but I don't know how to call this method, what's its path...) when I used Activity.this.method() I get the following error: No enclosing instance of the type Activity is accessible in scope Any Idea ? Eldhose M Babu Yes you can. In the adapter Add a new Field : private Context mContext; In the adapter Constructor add the
