In a Token Ring (IEEE 802.5) network, what specific action does the intended recipient station perform on the data frame as it passes around the ring? ⁹

The way the operands are chosen during program execution is

What is the primary advantage of keeping operands in CPU Registers compared to storing them in main memory?

The memory map below gives the contents of each of the locations of a simple memory.  Each of these locations uses 4-bit addresses and contains a 4-bit binary value.  Write the value accessed from memory and loaded into R0 after executing the following instruction.  Assume that r1 initially contains 0001 and r2 contains 001 1  

 LOAD  R0, [R1, R2]
