(Choose all that apply)
a. Reduce the size of graphics files
b.Transform all graphics into GIF files
c.Use fewer colors if possible without degrading graphic resolution
d.Convert all files to JPEG format
answer I got was A only
2.

| I agree with your answers jombeewoof, except I seem to remember reading something a while back about how jpeg, due to its compression, will speed performance in graphics displays. If that's true, then D would also be correct for number 1. But, dunno for sure. | |

| For 1 it's A & C. Reducing the size of the graphic as well as using fewer colors will speed up the page.
For 2 - when I do a search on google I get All of the above in one form or another. However a search on yahoo yields the same results as posted http://www.plauder-smilies.de/sad/nixweiss.gif | |

| Q1 I am not sure. I'd go for a,b,and c, as GIFs are generaly smaller then JPEGs.
Q2By the rules, your answer was definitly correct : AB and F. Same rules apply as in maths: calculate what's in the inside Brackets first then calculate results in outer brackets plus anything outside brackets.
your Q:What will the following search return?
dance and ((tango or waltz) or (Russian and African))
Consider AND as +. Consider OR as "one OR the other"
Options you can have :
Dance is going to stay at any result as outside the brackets and has the AND , which is effectively +.
Now you calculate inside brackets:
((tango OR waltz) OR (Russian+African))
possible results inside the inner brackets 1st:
(tango OR waltz) (Russian+African))
tango russianafrican
waltz russianafrican
Now you look at these results within outer brackets you get
tango OR russianafrican
waltz OR russianafrican
you see how at the end , because of OR you get only left OR the right side as the result so the final brackets calculation will be:
Tango or
WAltz or
russianafrican
"Dance" was a result in any case as outside the brackets. It had the word AND (so + whatever the result of the bracket calculation), therefore just place dance before each of those and you get the answers.
a.dance tango
b.dance waltz
f.dance Russian African
Hope this clarifies it.

| I doubt C will really make a whole lot of difference in speed since you do not degrade graphic's resolution. The difference in loading a black & White & 25 shades of grey vs the difference of Green & White & 10 other pretty colors isnt going to amount to squat (if anything). The graphics file size will still probrobly be about the same.
Depending on what sort of graphic files you use, converting them into GIF (we will probrobly loose quality though) or jpeg might decrease file size, but alas we were not given information about what graphic format is currently being used.
As for #2, ladygee hit it right on the money. | |

Just try creating two GIF files with same colours, one saved with 256 colours and one save with 7 colours. The file size of the fewer colours is smaller than the file with more colours. | |

| I think kel321 is correct for both questions.
Question 1. could be A or C but C says "without degrading graphic resolution". A is the only option a webmaster (like me) would choose. The other two answers are silly because gifs and jpegs are not interchangable. Jpegs = photos and graphics. Gifs = thumbnails, buttons and banners.
Question 2. is logic using "or" "and" but to make sure I tried it out too. Answer is OK.
