Select the correct answer. Which statement is true regarding the use of Kirchhoff’s laws?

A. The voltage change across a resistor is negative when you traverse in the opposite direction of the current.
B. Some current is lost at the junction due to resistance across all resistors in the circuit.
C. Every loop should contain junctions from where current branches out in different directions.
D. The voltage change across a resistor is zero when you traverse in the opposite direction of the current.
E. The sum of currents flowing into a junction is more than the sum flowing out of it.

Hyperactive media sales has 10 windows 7 laptop computers used by sales-people in the organization. each laptop computer has several customized applications that are used during the sales process as well as customer relationship management software. all of the applications on the laptops are difficult to configure and have large data files. if all of the laptops have current hardware, what is the easiest way to install windows 10 on them?

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
