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

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 is a calendar file – spring15 tells you that

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

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

5. One difference between ASCII and Unicode is ASCII is a newer code, Unicode is older ASCII has a smaller number of codes, Unicode has many more ASCII takes up more room per character than Unicode does 4. All of these are correct.

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

7. Charles Babbage imagined the ________ with the help of Ada Lovelace. abacus Difference Engine Enigma first electronic computer

8. Who wrote Visicalc? Steve Jobs and Bill Gates Bill Gates and Steve Ballmer Dan Bricklin and Bob Frankston Al Gore

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

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

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

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

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

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

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

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
