In a 32-bit program an address is a 32-bit value. In a 64-bit program an address is a 64-bit value (although only the low 48 bits are used). In a linear address space, the possible address space is 4GB. One note is that many hardware items are memory mapped to addresses.
However, this will not totally solve the Fedâs problem. Even when it was paying the banks 0.25% interest on reserves, the effective federal funds rate (the rate at which reserves at the Fed were actually being traded) was below 0.25%. This is why the Fed adopted a range for the federal funds rate of 0-0.25%.
From this rate, lenders determine their interest rates offered to borrowers, as well as the interest percentage paid to savings customers. From 2009 to 2010, the average bank prime loan rate set by the Federal Reserve was 3.5 percent, the lowest rate since 1957.
