What is the full file path for an Excel file name cis200 that is located on your C drive in your cis200 directory and lecture2 subdirectory?

C:\CIS200\LECTURE2\CIS200.XLS

Do you have enough memory on your hard drive to save this document? Your hard drive has .5 meg of memory left and your document is 25 pages. Each page has an average of 1600 characters and each

character is represented by a 16 bit unicode representation.

1600 characters per page * 16 bits/character = 25,600 bits per page

25,600 bits ÷ 8 bits per byte = 3200 bytes/page

3200 bytes/page *25 pages = 80,000 bytes

80,000 bytes < .5 meg 500,000 bytes

Explain the terms hardware, software, operating system and applications.

• Hardware – physical equipment• Software is code that tells the hardware what

to do• Operating System – software that interfaces

with the hardware to control basic functions such as keyboard input, printing, reading from memory etc.

• Applications – software designed to work with the operating system to perform specific task such as word processing, data manipulation etc.

What are the “variables” that will affect the results of a web search?

• Modify the keyword(s) you choose (home windows, Anderson windows)

• The syntax you include (+ “”) – And, Or, Not (windows not microsoft)

• The search engine you choose (try another search engine)

All of the above patients are asthma sufferers. A new medication that claims to increase lung capacity is being administered. What are the expected volume gains in liters for each patient if the drug claims to increase capacity by 15% for heavy smokers, 20% for light smokers and 30% for non-smokers(NS).

Question of the Day 6 (p.70 text)

Write an Excel formula in cell calc!B9, which can be copied down the column, to calculate the cost of the subfloor. The subfloor consists of two components – •Plywood sheets that cover the entire area of the kitchen -. One sheet of plywood contains 32 square feet. (assume cells E3:F9 were previously calculated)• Nails to install the sheet. Three nails are required for every square foot of sub-floor. Nails are sold in packages of 100.

Your contractor can use excess plywood and nails on other jobs – so he will only charge you for exactly the amount you need. (Hint: read the problem description for quantities)

Question of the Day 7

Question of the Day 8

• You have student loan for $5000 at 4.5% interest. No payment is required for 2 years but the loan accrues monthly interest. Once you begin paying the loan you have 10 years to finish payments. Calculate the monthly payment. (hint: try nesting your financial functions)

Question of the Day 8 - solution

1st calculate how much is owed in year 2 – and then use that as the basis for your payments in years 2 through 12

=PMT(Rate, NPER, PV, FV)

=PMT(.045/12,12*10, FV(.045/12,12*2,0, -5000),0)

Now Year 2 Year 12

a record of a table• Foreign Key – field in each of 2 tables that

“links” them..(1) same information, (2) same field type, (3) a primary key on at least one of the tables.

• Indexing – setting a table property to sort on a field (for improved retrieval)

• Binary Search – method of searching a “sorted” list by comparing the value to be found to the midpoint of the list. If its larger you discard the 1st half and then repeat until the value is found.
