8. Identify three basic differences between how your group would author a similar document and
how this author authored it (as you see it in the link).
First point is that one article is colored. So we can read it easily. But I think that if we print it, we
cost more money to print black and white only. Second point is that one article is written step by
step. It is easy for us to read and understand. Because when we read manual, we will see step first
time. So these article is easy to read. Third point is that there are many paragraph. It may do it
which is easy to read.
9. Study the following video carefully and then summarize 10 major points that you were able to
understand.
One point is that this video say that GPS is working by pare. Because GPS has to catch our place, it
is used satellite machine. And it use cell phone. Then cellphone location is used GPS location. And
GPS is can catch weather which is located cell phone. So we can get newer information of weather.
Ifon has these technique. And it has many options. For example, it can record our voice. It is useful
for us to want to record voice. And it can say one more what you did record. If it is done, our life is
more easily. The Ifon can use photo. It is useful. Because the Ifon can move any other place, when
we want to take a picture we can photo in that time.
10. Study the following video carefully and then summarize 10 major points that you were able to
understand.
This video show that how GPS is good. It is in Iphon. And it can zoom up of map. It is good for
us to find place where we want to go. Iphon have many functions. For example, it can see many
rate which are serching site rate. It is useful for author to search that how serching site is used. I
think that the Iphon is very useul cellphon. Because it has many functions, we can do many things.
For example, we can do email and talk. And it has many free softwear. So if we have short free
time, we can do it in short time. It is used map by GPS. Because it has useful GPS map, we will
not mistake. And we can go to place which we want to go.
