2. What is one way to get bonus points in this class? 1.Going to an Open Lab 2.Taking tests 3.Writing a paper 4.Coming to every lecture 2

3. A file with a path like c:\spring15\classes\cs101\sheet1.jpg 1.Is a picture file – the jpg tells you that 2.Is a text file – the folder classes tells you that 3.Is a spreadsheet – sheet1 tells you that 4.is a calendar file – spring15 tells you that 3

4. A file with a path like c:\spring15\classes\cs101\sheet1.jpg 1.Is stored at the root of the hard drive 2.Is stored on the floppy drive 3.Is stored in the “My Documents” folder 4.None of the above 4

5. If cell D18 contains =$A13+B$15, and the formula is copied to cell E15, what does it change to? 1.=$A13+B$15 2.=B10+C12 3.=$A10+C$15 4.=$A13+C$15 5

6. Who wrote Visicalc? 1.Steve Jobs and Bill Gates 2.Bill Gates and Steve Ballmer 3.Dan Bricklin and Bob Frankston 4.Al Gore 6

7. The value of the formula =5*3 + 8/2 1.27.5 2.19 3.31 4.18 7

8. How many megabytes are in 2 gigabytes? 1.200 2.2048 3.0.5 4.2 5.1024 8

9. If the formula =C5+1 were in cell C5 1.It would add 1 to the value already there 2.It would cause a precedence error 3.It would cause a #NAME error 4.It would cause a circular reference 9

10. The formula =sum(a3:a5) is the same as 1.=a3+a5 2.=a3*a5 3.=a3+a4+a5 4.=a3/a5 10

11. Being volatile is a property of 1.data on a hard drive 2.data in RAM 3.a printout of a document 4.a file burned on a CD 11

12. What does it mean to freeze a spreadsheet? 1.the sheet is hung up and needs to be reloaded 2.some columns and rows will not scroll when the rest of the sheet does 3.all formulas are locked and cannot be altered 4.an error has been found in a formula and it must be fixed before anything can be added 12

13. Secondary storage devices are 1.Not necessary these days, we have plenty of RAM 2.Useful because RAM is volatile and they are not 3.Faster than RAM to access data 4.Very sturdy, they can be handled roughly without problems 13

14. Cache memory 1.Is between RAM and the secondary storage devices 2.Is used to hold data which is going to be used frequently or in the near future 3.Holds data for a long time, it is not volatile 4.None of these is true 14

15. Virtual memory 15 A.is made possible by swapping data between RAM and a hard drive B.is only useful for playing VR games C.is theoretical, does not exist yet D.can never fill up

16. GigaHertz is a unit used to measure 16 A.capacity of a hard drive B.amount of RAM C.speed of a system clock D.number of pixels on a screen

17. Some CPUs are packaged as “quad cores”. This means 17 A.they run 4 times as fast as the old ones B.they have circuits equivalent to four individual CPUs C.they take up 4 times as much space as the earlier CPUs D.They need 4 times as much RAM
