3. 2. A file with a path like c:\spring19\classes\cs101\sheet1.gif
Is a picture file – the gif tells you that
Is a text file – the folder classes tells you that
Is a spreadsheet – sheet1 tells you that

4. 3. If an optical drive is labeled -R,
It can only be read from, not written to at all
It can be read from and written to many times
It can be written to once, read many times
It can only be written to, not read from

5. 4. A file with a path like c:\spring19\classes\cs101\sheet1.gif
Is stored at the root of the hard drive
Is stored on the floppy drive
Is stored in the “My Documents” folder
None of the above

6. 5. One difference between ASCII and Unicode is

4. All of these are correct.

7. 6. Gordon Moore
Came up with an observation about how the power of computers (complexity of circuits) was doubling every 18 months/2 years.
Is one of the founders of Intel.
Is an engineer
All of these are true

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

13. 12. The formula =sum(a3:a7) is the same as
=a3+a5 + a7
=a3*a7
=a3 + a4 + a5 + a6 + a7
=a3/a7

14. 13. The system clock tells you what the date and time are
sends out a regular signal to all computer components
is used to make sure the hard drive is spinning fast enough
is not a factor in how fast the computer runs

15. 14. Being volatile is a property of
data on a hard drive
data in RAM
a printout of a document
a file burned on a CD

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

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

18. 17. Which storage device would have problems with a magnet?
A hard drive
A memory stick (flash drive)
A DVD
An SD card

19. 18. Cache memory Is between RAM and the keyboard
Is used to hold data which is going to be used frequently or in the near future
Holds data for a long time, it is not volatile
None of these is true
