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%.
In the United States, the prime rate runs approximately 300 basis points (or 3 percentage points) above the federal funds rate, which is the interest rate that banks charge each other for overnight loans made to fulfill reserve funding requirements.he prime rate varies little among banks and adjustments are generally made by banks at the same time, although this does not happen frequently. The prime rate is currently 3.25% in the United States and 2.85% in Canada.
