Binding of Instructions and Data to Memory
Address binding of instructions and data to memory
addresses can happen at three different stages
Compile time: If memory location known a priori, absolute code can be generated; must recompile code if starting location changes Load time: Must generate relocatable code if memory location is not known at compile time
Routine is not loaded until it is called Better memory-space utilization; unused routine is never
Execution time: Binding delayed until run time if the process can be moved during its execution from one memory segment to another. Need hardware support for address maps (e.g., base and limit registers)
8.4
Base and Limit Registers
A pair of base and limit registers define the logical addressress protection with base and limit registers

Consider the swap price of $20.483/barrel. Relative to the forward curve price of $20 in 1 year and $21 in 2 years, we are overpaying by $0.483 in the first year, and we are underpaying by $0.517 in the second year Thus, by entering into the swap, we are lending the counterparty money for 1 year. The interest rate on this loan is

Physical Versus Financial Settlement (cont’d)
• Whatever the market price of oil, the net cost to the buyer is the swap price, $20.483
0.517 / 0.483 1 7%
Given 1- and 2-year zero-coupon bond yields of 6% and 6.5%, 7% is the 1-year implied forward yield from year 1 to year 2
• If the deal is priced fairly, the interest rate on this loan should be the implied forward interest rate

• Server receiving request message executes command included in message
– Retrieves Web page file from disk and creates a response message to send back to client
• Web browser requests files from Web server and uses the Internet as the transportation medium
– Request formatted by browser using HTTP and sent to server computer
– Identical in structure to request message (slightly different function)
• Response header line indicates server HTTP version, response status, status information explanation
• Web browser: a type of Web client software • Platform neutrality is the ability of a network to connect
devices using different operating systems
– Critical in rapid spread, widespread Web acceptance
• Software tools to create dynamic Web pages
– Microsoft , Apache Software Foundation Hypertext Preprocessor (PHP) and Adobe ColdFusion
