This set of MCQs helps students to learn about storage Management in compiler design, defined as when the target program executes then it runs in its own logical address space in which the value of each program has a location. The logical address space is shared among the compiler, operating system and target machine for management and organization.
Which of the following is not a weighted code?
Suppose that a bus has 16 data lines and requires 4 cycles of 250 nests each to transfer data. The bandwidth of this bus would be 2 Megabytes/sec. If the cycle time of the bus was reduced to 125 nsecs and the number of cycles required for transfer stayed the same what would the bandwidth of the bus?
