Write short and sharp answers to the following questions. Show all your work and reasoning in the
calculations.
9. Remember Moore’s Law of Processor Technology (thus, processor speed) and Jakob Nielsen’s Law of
Bandwidth. Express Moore’s Law in terms of Nielsen’s Law of Bandwidth, i.e., find out the annual per cent
increase of the number of transistors in the processor (indicating the processor speed) with the processor price
staying the same.
To paraphrase the question further: By how much does the speed of the best Intel CPU increase a year on the
average? Make sure that your answer is given as percentage.
PS:
You are expected to show all your work and to find a closed-form formula to get full credit. This implies that
you actually do not need a calculator to answer this question.

Exhibit 1
Wrong use of the VLOOKUP formula
A lookup table with 3 columns and 10 rows has been created to store the IDs, departments, and letter grades of 10
students as shown in Exhibit 1. You want to query the information about a given student whose ID is "138660" as
seen in cell H27. After these preparations you type a formula by using the VLOOKUP function of MS-Excel and
then press "ENTER" to see the result of it. Finally in order to be sure about the result of the formula you just go to
"Student ID" column of the "Lookup Table" (Column B) and browse the ID "138660" used in the formula.
But surprise! Even if the formula is logically true, it does not give the true solution. What was your fault? What
should have been the correct formulae to be typed in cells G30 and H30?

Exhibit 2
As you know, two-way tables allow us to vary two inputs, one along the row and one along the column, and
calculate one output in the body of the table. The above example illustrates this, where the row input and column
input both vary, and a single output (namely, monthly payment) is calculated.
Now, you asked to specify both the "row input cell" and the "column input cell" of the monthly payment data
table by giving the addresses of those cells (such as A1) in the Table window as shown in Exhibit 2. Which cell
addresses are you going to specify for the row input cell and for the column input cell?
(2 pts)
HINT:
Both of the two cell addresses must be absolute addresses. One will contain the annual interest rate and the other
will contain the down payment
Row input cell:?
Column input cell=?

18. When the first MP3 players came out (for example: Rio Diamond), they had only 32 MB built-in memory. Now Apple
iPods, Apple nano iPods, Creative and Samsung MP3 players etc. offer 40-60 GB storage capacity—virtually endless
streaming of your MP3 song files.
A similar phenomenon has been observed with chip based cards such as multimedia cards (MMC) and secure digital cards
(SD and micro SD). Now Extremem III SDHC cards of SanDisk can offer up to 16 GB capacity in devices of consumer
electronics.
Also USB flash memory drives have gone a long way in their storage capacity. Do you remember the first USB 1.0 pen
drives of just 16 MB? SanDisk introduced in May 2007 a brand-new model called Cruzer® Contour™ USB Flash
Drive with 8 GB storage capacity in your jean pocket! These rapidly occurring events in secondary portable storage
devices indicate which of the following?
(a) Parkinson's Law of Data according to which data expands to fill in the space available
(b) Gates' Law which states that software's speed halves every 18 months
(c) Murphy's Law which is due Edward A. Murphy, Jr., one of the engineers on the rocket-sled experiments
that were done by the U.S. Air Force in 1949 to test human acceleration.
(d) Moore's Law which is interpreted today as the doubling of CPU performance every 18 months.
(e) Jakob Nielsen’s Law of Bandwidth which states that a high-end user's connection speed grows by 50% per
year.
19. Which of the following situations is an example for incompatibility between two software products?
(a) The celebrated PC game "Counter Strike:Condition Zero" cannot be played under the vintage operating
system MS-Windows 95.
(b) Huge data files compressed with WinRAR 3.40 cannot be opened (uncompressed) with WinZip 8.0.
(c) You cannot read or write on a 750 MB ZIP disk in a 250 MB Iomega ZIP drive.
(d) a) and b)
(e) All of a), b) and c)
