0
00:01:16,280 --> 00:01:19,352
...unlock the classrooms ...unlock the
bathrooms...

1
00:01:19,440 --> 00:01:20,793
...prepare attendance sheets..

2
00:01:21,160 --> 00:01:25,711
Man, l can't believe we have to do all these
things before school starts£¡

3
00:01:25,800 --> 00:01:26,949
And there's more£¡

4
00:01:27,040 --> 00:01:29,713
There must be an easier way to get all this
stuff done.

5
00:01:29,800 --> 00:01:33,076
There is, Ralphie. Find another class to do it£¡

6
00:01:33,160 --> 00:01:36,197
But all the other classes have done it, Wanda.

7
00:01:36,280 --> 00:01:38,953
lt's our turn to open up the school.

8
00:01:39,040 --> 00:01:40,075
Chill out, guys...

9
00:01:40,160 --> 00:01:44,438
there must be a way to get all these chores
done without actually having to do them£¡

10
00:01:44,520 --> 00:01:48,752
Ay, laddie, l've been dreamin' that dream for
years£¡

11
00:01:49,040 --> 00:01:51,156
This just came from Mr. Ruhle.

12
00:01:51,240 --> 00:01:54,277
He said he was expectin' it and asked you kids
to set it up.

13
00:01:54,400 --> 00:01:57,870
Oh no£¡ Not another thing to do£¡

14
00:01:58,200 --> 00:02:00,350
Well, better get to work -

15
00:02:01,040 --> 00:02:04,237
Ruhle's school will be open for business afore
you know it.

16
00:02:04,960 --> 00:02:06,518
l wonder what's in here.

17
00:02:09,280 --> 00:02:10,918
Ah£¡ Good morning, class£¡

18
00:02:11,080 --> 00:02:12,513
MS FRlZZLE£¡

19
00:02:13,080 --> 00:02:17,631
Mr.Ruhle's new super-duper computer has
arrived£¡

20
00:02:18,360 --> 00:02:22,956
A computer£¡ That's it£¡ We'll get the computer
to do our jobs£¡

21
00:02:23,040 --> 00:02:24,678
Great idea£¡

22
00:02:24,760 --> 00:02:26,273
Yeah£¡ A computer£¡

23
00:02:26,360 --> 00:02:29,591
Hmmm, computers have helped men and
women live in space...

24
00:02:29,680 --> 00:02:31,830
doing a few chores should be a piece of cake -

25
00:02:31,960 --> 00:02:34,394
make that a byte of cake£¡

26
00:02:36,880 --> 00:02:42,477
Let's see, this computer is a state-of-the-art
Eniac-Maniac 2000,

27
00:02:42,560 --> 00:02:47,111
with a gazillion gigabyte hard drive, more RAM
than a traffic jam,

28
00:02:47,200 --> 00:02:50,556
and a flippity-floppity zippity-doodah floppy
drive£¡

29
00:02:50,640 --> 00:02:52,278
Cool£¡ Let's set it up£¡

30
00:02:53,240 --> 00:02:58,360
...and voila£¡ l officially declare this baby ready
for action£¡

31
00:02:59,520 --> 00:03:02,193
Go ahead, Carlos. Turn it on.

32
00:03:03,480 --> 00:03:04,879
Don't forget the printer£¡

33
00:03:05,240 --> 00:03:06,389
Got it£¡

34
00:03:11,320 --> 00:03:13,959
Uh-oh. lt stopped.

35
00:03:14,080 --> 00:03:16,150
How do we make it do something?

36
00:03:16,240 --> 00:03:19,232
Right now, this computer is just an idle
machine -

37
00:03:19,320 --> 00:03:22,073
it needs instructions to tell it what to do.

38
00:03:22,720 --> 00:03:23,994
What instructions?

39
00:03:24,080 --> 00:03:27,550
We can't make it do our chores, because we
don't know how it works£¡

40
00:03:27,640 --> 00:03:29,790
Well, we better figure it out fast£¡

41
00:03:29,960 --> 00:03:35,751
What we need is someone who really knows
computers£¡ We need an expert£¡

42
00:03:36,520 --> 00:03:38,511
Somebody call my name?

43
00:03:38,600 --> 00:03:40,033
MlKEY£¡£¡£¡

44
00:03:40,240 --> 00:03:41,878
Hola, Frizzlers£¡

45
00:03:42,720 --> 00:03:46,872
l was coming in early to clean out my desk
when l heard your yelp for help.

46
00:03:47,400 --> 00:03:51,598
Oh, Mikey, look what your big brother has for
you.

47
00:03:51,680 --> 00:03:54,638
Wow£¡ An Eniac Maniac£¡

48
00:03:54,720 --> 00:03:55,948
Fresh out of the box£¡

49
00:03:56,040 --> 00:04:00,636
We need you to do whatever you have to do so
it'll do all the morning chores.

50
00:04:01,200 --> 00:04:02,918
...No problem.

51
00:04:03,000 --> 00:04:05,639
Mikey's a whiz when it comes to computers£¡

52
00:04:05,720 --> 00:04:07,870
A chip off my own block£¡

53
00:04:08,520 --> 00:04:10,909
Well, since classes start in half an hour,

54
00:04:11,000 --> 00:04:14,117
l think we should take chances, make
mistakes...

55
00:04:14,200 --> 00:04:16,953
and let Mikey upload the workload£¡

56
00:04:17,040 --> 00:04:18,109
All right£¡

57
00:04:18,200 --> 00:04:19,713
Go to it£¡ Do it, Mikey£¡

58
00:04:19,880 --> 00:04:24,112
You know a computer can do a lot more than
just flash pictures on a screen.

59
00:04:24,760 --> 00:04:27,115
Here, Carlos, attach this to the flagpole...

60
00:04:27,240 --> 00:04:29,037
Aye-aye, computer dude£¡

61
00:04:29,120 --> 00:04:32,999
And Keesha how 'bout plugging this into the
coffee machine in the teacher's lounge?

62
00:04:33,080 --> 00:04:35,116
Arnold?... This one goes to the bell.

63
00:04:35,200 --> 00:04:37,555
DA, this one's for the timer on the sprinkler
valve.

64
00:04:38,040 --> 00:04:40,998
And who wants to connect this one to the door
control?

65
00:04:41,320 --> 00:04:42,355
l'll do it.

66
00:04:42,520 --> 00:04:43,953
Here you go Wanda.

67
00:04:46,880 --> 00:04:48,393
Mission accomplished Mikey.

68
00:04:48,560 --> 00:04:50,073
All plugged in£¡

69
00:04:50,200 --> 00:04:51,838
All done, Mikey£¡

70
00:04:52,360 --> 00:04:55,238
Great£¡ Now greet the folks, Carlos£¡

71
00:04:55,920 --> 00:04:59,151
Hi, how are ya, nice to see ya£¡

72
00:04:59,240 --> 00:05:02,152
Thanks for comin' to school and enjoy your
day£¡

73
00:05:04,360 --> 00:05:05,918
Perfect£¡ Now...

74
00:05:06,240 --> 00:05:08,117
l'll type in this...

75
00:05:08,240 --> 00:05:11,277
and that... tell it to do this...

76
00:05:13,160 --> 00:05:15,879
...now l'll save what l've typed...

77
00:05:17,240 --> 00:05:21,472
Finito, amigos£¡ lnstructions written and stored£¡

78
00:05:21,800 --> 00:05:25,634
Just click on the school icon and watch your
jobs get done£¡

79
00:05:38,560 --> 00:05:41,518
Hi, how are ya, nice to see ya£¡

80
00:05:41,600 --> 00:05:44,398
Thanks for comin' to school and enjoy your
day£¡

81
00:05:59,120 --> 00:06:00,473
Way to go£¡

82
00:06:00,560 --> 00:06:01,675
Mikey did it£¡

83
00:06:01,760 --> 00:06:05,548
Like l always say, when you need a pro, call
my bro£¡

84
00:06:05,920 --> 00:06:09,913
Yeah, well, l guess l better go clean up my
desk now...

85
00:06:10,840 --> 00:06:13,912
Boy, l'd love to know what it's like in there.

86
00:06:14,720 --> 00:06:18,190
l mean what really happens to my instructions
once l've typed them in?

87
00:06:18,920 --> 00:06:22,151
Ah£¡ Now there's a question we can save in a
file called...

88
00:06:22,240 --> 00:06:24,435
Excellent idea for a field trip

89
00:06:24,520 --> 00:06:25,635
A field trip?

90
00:06:25,720 --> 00:06:28,439
Sure - and why don't you go test it out?

91
00:06:28,520 --> 00:06:29,316
Me??

92
00:06:29,480 --> 00:06:32,631
You mean he gets to go inside the
computer??

93
00:06:32,720 --> 00:06:33,914
What about us?

94
00:06:34,000 --> 00:06:36,434
We've got the school to open, remember?

95
00:06:36,600 --> 00:06:40,991
So, Mikey - slip on these earphones for your
own guided tour.

96
00:06:41,320 --> 00:06:44,869
Awesome£¡ My own personal guided tour£¡

97
00:06:45,560 --> 00:06:47,198
Have fun, Mikey£¡

98
00:06:48,240 --> 00:06:50,800
We said...have fun£¡

99
00:06:50,880 --> 00:06:52,233
Will do, Carlos.

100
00:06:52,320 --> 00:06:54,231
Ready to be modified, Ms Frizzle.

101
00:06:54,320 --> 00:06:58,233
Well, then, as my micro cousin Chip would
say£º

102
00:06:58,320 --> 00:07:01,756
to take a risk - make like a floppy disk£¡

103
00:07:01,840 --> 00:07:04,400
lt's the quick way to send instructions inside.

104
00:07:13,440 --> 00:07:16,671
Wah-hoooooooo£¡£¡£¡

105
00:07:20,640 --> 00:07:22,790
Hey£¡ What's going on out there?

106
00:07:23,680 --> 00:07:26,877
Hi, how are ya', nice to see ya'£¡

107
00:07:26,960 --> 00:07:29,838
Thanks for comin' to school and enjoy your
day£¡

108
00:07:31,520 --> 00:07:36,674
ls it just me, or is the computer doing
everything on our list all over again?

109
00:07:37,160 --> 00:07:39,993
Something's definitely wrong with the
computer£¡£¡

110
00:07:40,080 --> 00:07:42,594
And Mikey's the only one who can fix it£¡

111
00:07:43,080 --> 00:07:45,753
And Mikey's inside the computer£¡£¡£¡

112
00:07:45,880 --> 00:07:48,110
Mikey...

113
00:07:53,320 --> 00:07:56,153
Hi, how are ya, nice to see ya'£¡

114
00:07:56,240 --> 00:07:59,277
Thanks for comin' to school and enjoy your
day£¡

115
00:08:02,240 --> 00:08:06,199
What are we gonna do? What are we gonna
do? What are we gonna do?

116
00:08:06,520 --> 00:08:09,717
We have to fix it before Mr. Ruhle gets here£¡

117
00:08:09,800 --> 00:08:11,597
Why don't we just turn it off?

118
00:08:11,680 --> 00:08:14,274
Turn it off? We can't do that, DA£¡

119
00:08:14,360 --> 00:08:18,114
Something terrible might happen to Mikey£¡
We've gotta get him back£¡

120
00:08:19,960 --> 00:08:24,078
S'cuse me, laddie, but would you mind tellin'
me what's goin' on here?£¡

121
00:08:24,160 --> 00:08:26,116
MR. McCLEAN£¡£¡£¡

122
00:08:26,280 --> 00:08:30,512
We're just experiencing a little technical
difficulty,

123
00:08:30,600 --> 00:08:33,512
but l'm sure it'll be fine in no time, right class?

124
00:08:33,680 --> 00:08:38,435
Hmmph. Well l'd better be going to see if it's
all fine in the teacher's lounge.

125
00:08:40,240 --> 00:08:42,674
Mikey£¡ Mikey£¡

126
00:08:43,160 --> 00:08:46,789
Ahhh£¡ A computer is complicated - he could
be anywhere£¡

127
00:08:46,880 --> 00:08:48,632
MlKEY£¡£¡£¡£¡

128
00:08:48,720 --> 00:08:52,030
He probably can't hear you because of the
earphones.

129
00:08:52,120 --> 00:08:54,634
You're right, Feebs, l forgot.

130
00:08:54,720 --> 00:08:58,269
Maybe Mikey did something in there that made
the computer go crazy£¡

131
00:08:58,400 --> 00:09:02,757
Not my brother Mikey£¡ He knows what he's
doing... l think...

132
00:09:03,080 --> 00:09:07,153
Maybe we better go in there and get him out
before Mr. Ruhle gets here£¡

133
00:09:07,240 --> 00:09:10,277
Oh£¡ What a splendid idea, Phoebe£¡

134
00:09:10,640 --> 00:09:14,349
Don't you just love it when they solve
problems, Liz?

135
00:09:26,760 --> 00:09:29,593
Prepare to upload, class£¡

136
00:09:30,280 --> 00:09:32,555
Wait a minute, we all can't go£¡

137
00:09:32,640 --> 00:09:36,189
What if Mr. McClean comes back? Or Mr.
Ruhle gets here early?

138
00:09:36,920 --> 00:09:39,115
You're right£¡ l'll stay behind£¡

139
00:09:39,480 --> 00:09:43,519
And so will Liz. See you in ''a bit'', Arnold£¡

140
00:09:44,680 --> 00:09:49,231
A diskette a daskette
the-bus'll-turn-into-a-floppy-disk-if-we-ask-it£¡

141
00:10:01,400 --> 00:10:04,119
So this is where the floppies go£¡

142
00:10:04,200 --> 00:10:06,714
To the drive-in disk-o£¡

143
00:10:06,800 --> 00:10:07,710
CAR-LOS£¡

144
00:10:08,200 --> 00:10:10,350
Look at that thing spin£¡

145
00:10:10,440 --> 00:10:13,557
Hey£¡ What's with the metal toothbrush sliding
across the disk?£¡

146
00:10:13,640 --> 00:10:18,031
Ah£¡ lt's reading instructions and other
information stored on the floppy disk.

147
00:10:18,120 --> 00:10:22,398
lnformation stored on a disk gets changed into
electrical signals

148
00:10:22,480 --> 00:10:24,789
and sent on to the main part of the computer.

149
00:10:25,480 --> 00:10:28,995
Um, Ms Frizzle, is that thing going to read us?

150
00:10:29,080 --> 00:10:31,116
l mean, it's getting awfully close.

151
00:10:31,200 --> 00:10:35,671
Not to worry, Ralphie£¡ OK Bus do your stuff.

152
00:10:42,720 --> 00:10:46,599
So...where's Mikey? l don't see him anywhere.

153
00:10:46,760 --> 00:10:48,034
Waitaminute£¡

154
00:10:48,120 --> 00:10:51,874
Mikey was going to find out what happened to
his instructions, right?

155
00:10:51,960 --> 00:10:52,790
Right£¡

156
00:10:52,880 --> 00:10:55,758
lnstructions are information, right?

157
00:10:55,840 --> 00:10:56,590
Right£¡

158
00:10:56,680 --> 00:11:01,117
And the information is in those flashing
electrical signals...right?

159
00:11:01,200 --> 00:11:02,076
Right£¡

160
00:11:02,160 --> 00:11:05,357
So if we follow the signals - we find Mikey£¡

161
00:11:05,440 --> 00:11:09,592
Good thinking, Wanda£¡ Just follow the
yellow-lit road£¡

162
00:11:09,680 --> 00:11:13,150
And as l always say, 'why walk when you can
ride'?

163
00:11:13,880 --> 00:11:17,236
Time to skateboard across the motherboard.

164
00:11:22,280 --> 00:11:26,876
Wha-hah-hoooooo£¡£¡£¡£¡£¡£¡

165
00:11:34,320 --> 00:11:39,030
Wow£¡ Where are we? What is this place?

166
00:11:39,120 --> 00:11:42,954
lt's the motherboard, the heart of the
computer£¡

167
00:11:43,120 --> 00:11:44,838
lt's full of wires£¡

168
00:11:45,000 --> 00:11:48,072
And the wires are carrying electrical signals

169
00:11:48,160 --> 00:11:50,594
like the ones coming in from our floppy disk.

170
00:11:50,680 --> 00:11:54,639
This must be how information travels around
the computer. lt goes...

171
00:11:54,720 --> 00:11:56,233
...Electricity Express£¡

172
00:11:56,400 --> 00:11:59,836
Simply electrifying, isn't it, class?£¡

173
00:12:00,720 --> 00:12:06,113
The information is heading for that big square
thingy in the middle of the motherboard£¡

174
00:12:06,200 --> 00:12:08,555
Maybe Mikey's in here£¡ C'mon£¡

175
00:12:12,440 --> 00:12:14,351
Nope£¡ No Mikey.

176
00:12:14,440 --> 00:12:16,431
What's going on in there anyway?

177
00:12:16,520 --> 00:12:18,033
lt's all wires and lights£¡

178
00:12:18,120 --> 00:12:21,908
This part of the computer is in charge of
everything that happens inside.

179
00:12:22,000 --> 00:12:25,834
lt handles every bit of information that comes
in - and goes out.

180
00:12:25,920 --> 00:12:28,912
You mean like computer headquarters?

181
00:12:29,000 --> 00:12:30,831
Just like the principal's office£¡

182
00:12:30,920 --> 00:12:36,836
Which is why it's called the Central
Processing Unit - or the CPU for short.

183
00:12:36,920 --> 00:12:40,469
Gee, the information doesn't stay in the CPU
very long.

184
00:12:40,560 --> 00:12:42,312
lt gets sent right back out again.

185
00:12:42,400 --> 00:12:45,153
So Mikey must have come to the CPU...

186
00:12:45,240 --> 00:12:47,117
then gone someplace else.

187
00:12:47,200 --> 00:12:49,953
C'mon, let's keep following the information...

188
00:12:50,040 --> 00:12:52,076
he's gotta be in here somewhere£¡

189
00:12:53,720 --> 00:12:58,236
Bravo£¡ You have just entered the computer's
random access memory -

190
00:12:58,320 --> 00:12:59,992
also known as RAM.

191
00:13:00,080 --> 00:13:04,392
A computer can't follow a list of instructions if
it can't remember them.

192
00:13:04,480 --> 00:13:08,871
These RAM chips hold the instructions while
the CPU follows them.

193
00:13:09,200 --> 00:13:10,792
Cool£¡

194
00:13:10,880 --> 00:13:13,348
Hi, how are ya, nice to see ya'£¡

195
00:13:13,440 --> 00:13:16,000
Thanks for comin' to school and enjoy your
day£¡

196
00:13:16,160 --> 00:13:17,479
What's goin' on 'ere?

197
00:13:17,560 --> 00:13:18,959
The entire school's gone wacky£¡

198
00:13:19,040 --> 00:13:20,268
Whoaaaaa£¡£¡£¡

199
00:13:20,440 --> 00:13:24,513
One thing about being in Ms Frizzle's
class...it's never boring...

200
00:13:26,680 --> 00:13:27,829
OH NO£¡£¡£¡

201
00:13:28,720 --> 00:13:32,156
Hey, guys, guys, you gotta do something
quick£¡

202
00:13:32,240 --> 00:13:35,789
No, that's not the way to get information into
the computer£¡

203
00:13:36,160 --> 00:13:37,115
l know£¡

204
00:13:38,200 --> 00:13:43,069
Help£¡ Mr. McClean is up the flag pole and the
buses are coming£¡

205
00:13:43,560 --> 00:13:46,154
Carlos? Mikey?

206
00:13:47,960 --> 00:13:49,757
Heeelllppppp£¡£¡£¡£¡

207
00:14:01,360 --> 00:14:04,636
Hi, how ya', nice to see ya'.

208
00:14:04,720 --> 00:14:07,632
Thanks for comin' to school, enjoy your day.

209
00:14:11,160 --> 00:14:12,354
Hurry up in there£¡£¡

210
00:14:13,280 --> 00:14:15,032
What's the problem, Arn?

211
00:14:15,120 --> 00:14:16,269
What's the problem?

212
00:14:16,400 --> 00:14:19,153
Flags are flying, bells are ringing, kids are
coming--

213
00:14:19,240 --> 00:14:20,514
Kids are coming??£¡

214
00:14:20,640 --> 00:14:22,198
They're here now£¡

215
00:14:22,280 --> 00:14:24,236
That means Mr. Ruhle won't be far behind£¡

216
00:14:24,320 --> 00:14:25,230
Got'cha£¡

217
00:14:26,480 --> 00:14:29,358
Whaaaaaaaaaaaaaaaaa£¡

218
00:14:29,680 --> 00:14:31,750
We know Mikey's in here somewhere.

219
00:14:31,840 --> 00:14:33,159
The question is, where?

220
00:14:33,240 --> 00:14:36,437
Well, he's not in the floppy disk drive or the
CPU.

221
00:14:37,120 --> 00:14:39,839
Wherever he is, we've gotta find him fast£¡

222
00:14:39,920 --> 00:14:41,876
lt's almost time for school to start£¡

223
00:14:41,960 --> 00:14:43,757
Where else does the information go?

224
00:14:43,840 --> 00:14:49,472
Wait wait wait£¡ Mikey said he stored his
instructions permanently, remember?

225
00:14:49,560 --> 00:14:53,712
You're right, Wan£¡ So where in this computer
does information get stored?

226
00:14:54,240 --> 00:14:57,073
Ah£¡ Excellent question, Carlos£¡

227
00:14:57,160 --> 00:15:00,789
You store information you want to keep in the
hard drive£¡?

228
00:15:00,880 --> 00:15:03,235
The hard drive£¡? Where's that?

229
00:15:03,320 --> 00:15:05,834
Oh£¡ l think it's that way£¡

230
00:15:06,440 --> 00:15:07,839
Alright£¡

231
00:15:16,600 --> 00:15:20,639
Welcome to the Hard Drive, where disks are
hard instead of floppy.

232
00:15:20,720 --> 00:15:24,349
This is the place where instructions and other
information are stored

233
00:15:24,440 --> 00:15:28,149
so they can be used again and again
whenever they're needed.

234
00:15:28,440 --> 00:15:29,555
Hey Mikey£¡

235
00:15:29,880 --> 00:15:32,519
l don't think he can hear us.

236
00:15:32,600 --> 00:15:33,715
Let's get down there£¡

237
00:15:40,040 --> 00:15:42,429
Carlos£¡ What are you guys doin' in here?

238
00:15:42,520 --> 00:15:44,715
We've been looking all over for you£¡

239
00:15:44,800 --> 00:15:47,075
Something's wrong with the computer£¡

240
00:15:47,160 --> 00:15:47,990
Wrong?

241
00:15:48,120 --> 00:15:51,396
But l've been all through this computer, and it's
working great£¡

242
00:15:51,480 --> 00:15:54,950
The information's coming rom the keyboard
and the floppy disk

243
00:15:55,040 --> 00:15:57,190
and getting changed into electrical signals

244
00:15:57,280 --> 00:15:58,633
just like it's supposed to...

245
00:15:58,720 --> 00:16:00,631
...and the CPU's deciding what to do with 'em.

246
00:16:01,360 --> 00:16:03,510
Everything's A-Okay in here.

247
00:16:03,600 --> 00:16:06,353
But it's not okay out there£¡ We need to get out
of here now£¡

248
00:16:10,880 --> 00:16:13,758
The computer's doing our jobs over and over
again

249
00:16:13,920 --> 00:16:18,072
No sweat£¡ Since computers send information
out as well as bring it in,

250
00:16:18,160 --> 00:16:20,469
we'll just go out with the output.

251
00:16:21,880 --> 00:16:25,077
Quick£¡£¡ This information's on its way out to the
printer.

252
00:16:25,400 --> 00:16:27,277
Let's go with the flow£¡

253
00:16:29,600 --> 00:16:30,828
Coming, Ms Frizzle?

254
00:16:30,920 --> 00:16:32,558
Try and stop me£¡

255
00:16:34,560 --> 00:16:36,869
Wah -ha- ha- hoooooooo£¡£¡£¡£¡£¡

256
00:17:05,680 --> 00:17:07,079
We're getting printed£¡

257
00:17:07,400 --> 00:17:10,119
Okay, Bus- do your stuff£¡

258
00:17:21,800 --> 00:17:25,349
You're back£¡ You're back£¡ You're back£¡ Thank
you.

259
00:17:25,440 --> 00:17:26,839
Get a grip, Arn£¡

260
00:17:26,920 --> 00:17:29,832
Hi, how are ya', nice to see ya'£¡

261
00:17:29,920 --> 00:17:32,832
Thanks for coming to school and enjoy your
day.

262
00:17:33,360 --> 00:17:36,432
You weren't kidding. lt is going crazy out here.

263
00:17:38,440 --> 00:17:40,874
The flag is going up again.

264
00:17:42,360 --> 00:17:43,679
And again£¡

265
00:17:43,760 --> 00:17:46,035
And the sprinklers are flooding the lawn.

266
00:17:46,160 --> 00:17:49,072
And Mr. Ruhle will be here any minute£¡

267
00:17:49,560 --> 00:17:52,358
Well, don't pout - we're going to figure this out.

268
00:17:53,760 --> 00:17:55,239
What are you doing, Mikey?

269
00:17:55,320 --> 00:17:56,594
Printing out my program.

270
00:17:56,680 --> 00:17:58,591
Program? What's a program?

271
00:17:58,720 --> 00:18:02,395
Over to you, Ms Frizzle£¡ Give 'em the hype
while l type.

272
00:18:02,520 --> 00:18:04,112
My pleasure, Mikey.

273
00:18:04,200 --> 00:18:06,111
A computer is just a machine -

274
00:18:06,200 --> 00:18:09,158
it needs instructions to tell it what to do and
how to do it.

275
00:18:09,240 --> 00:18:13,870
That's what a program is - a list of instructions
the computer understands.

276
00:18:13,960 --> 00:18:17,714
And if there's even one teeny-weeny mistake
in the program -

277
00:18:17,800 --> 00:18:19,552
everything goes kaflooey£¡

278
00:18:19,640 --> 00:18:24,634
So you think maybe you made a little mistake
in what you told the computer to do?

279
00:18:24,720 --> 00:18:29,396
Me? Mistake? l doubt it, but there's a first time
for everything.

280
00:18:40,000 --> 00:18:41,718
Here's your program, Mikey£¡

281
00:18:42,040 --> 00:18:44,235
Hmmmm. Looks good to me...

282
00:18:44,320 --> 00:18:48,677
unlock and open the doors... Raise the flag...
Turn on the sprinklers.

283
00:18:48,760 --> 00:18:51,433
Turn off the sprinklers... recorded message...

284
00:18:51,520 --> 00:18:54,159
printer... coffee machine... bell...

285
00:18:54,240 --> 00:18:55,514
But what's this?

286
00:18:55,600 --> 00:18:58,910
Repeat everything every minute, except on
Saturday and Sunday.

287
00:18:59,000 --> 00:19:02,151
Every minute? lt's supposed to say every day£¡£¡£¡

288
00:19:02,640 --> 00:19:05,279
l...l made a mistake£¡

289
00:19:05,360 --> 00:19:08,352
lt's the only way to take chances and get
messy£¡

290
00:19:08,520 --> 00:19:11,671
No wonder everything's turning on and off
every minute.

291
00:19:11,760 --> 00:19:14,911
The computer's doing just what you told it to
do in the program£¡

292
00:19:15,080 --> 00:19:18,231
Which is all computers ever do, right?

293
00:19:18,320 --> 00:19:21,517
lf we program them correctly, they do what we
want.

294
00:19:21,600 --> 00:19:26,196
But if we put garbage in ...we get garbage out£¡

295
00:19:26,520 --> 00:19:30,752
Yeah - a computer is only as smart as the
person who puts in the instructions.

296
00:19:30,840 --> 00:19:32,876
l can fix this in a jif.

297
00:19:33,200 --> 00:19:36,158
l'll just change the word ''minute'' to ''day'',

298
00:19:36,240 --> 00:19:38,708
and store this new, improved program in the
hard drive.

299
00:19:41,840 --> 00:19:44,434
Finito, amigos. Let's test it£¡

300
00:19:51,800 --> 00:19:53,392
We're up and running£¡

301
00:19:54,240 --> 00:19:55,514
Good morning, everybody£¡

302
00:19:55,840 --> 00:19:57,273
Mr. Ruhle£¡

303
00:19:57,640 --> 00:20:00,757
Hi, how are ya', nice to see ya'.

304
00:20:00,840 --> 00:20:03,752
Thanks for comin' to school and enjoy your
day£¡

305
00:20:05,120 --> 00:20:07,350
Hmm£¡ There's nobody out here£¡

306
00:20:07,680 --> 00:20:09,272
What's going on?£¡£¡£¡

307
00:20:12,240 --> 00:20:15,277
The school is getting ready by itself£¡

308
00:20:16,840 --> 00:20:19,229
Ah, um, it's not really.

309
00:20:19,320 --> 00:20:22,471
l mean, we uh...we helped it along a little.

310
00:20:22,800 --> 00:20:24,870
Oh, you did, did you?

311
00:20:24,960 --> 00:20:28,111
l see you set up my new computer, as l
requested.

312
00:20:28,200 --> 00:20:31,829
But did l say anything about programming it?

313
00:20:31,960 --> 00:20:35,509
Er, ah, no...but we just thought -

314
00:20:36,240 --> 00:20:38,800
Don't you know how to follow instructions?

315
00:20:38,920 --> 00:20:41,354
Yes, sir, and so does your computer£¡

316
00:20:41,440 --> 00:20:44,637
ln fact, that's all it knows how to do.

317
00:20:44,720 --> 00:20:48,156
That computer is only as smart as the
instructions you give it.

318
00:20:48,240 --> 00:20:50,276
And Mikey gave it some good ones£¡

319
00:20:50,400 --> 00:20:55,793
And am l supposed to be pleased with this?
Because l'm not.

320
00:20:56,480 --> 00:20:58,755
l'm thrilled£¡

321
00:21:00,240 --> 00:21:04,074
All right, laddies, l've had it with your bright
ideas£¡

322
00:21:04,160 --> 00:21:05,229
Mr. McClean£¡

323
00:21:06,360 --> 00:21:07,713
Mr. Ruhle£¡

324
00:21:08,760 --> 00:21:10,990
Would ya like some coffee, sir?

325
00:21:11,080 --> 00:21:12,354
Thank you, Mr. McClean.

326
00:21:12,440 --> 00:21:15,318
Just think, thanks to Ms Frizzle's class,

327
00:21:15,400 --> 00:21:18,915
we'll never have to make coffee ourselves
again.

328
00:21:19,040 --> 00:21:20,519
We won't?

329
00:21:20,640 --> 00:21:24,189
Nope, the computer is going to do it£¡

330
00:21:24,280 --> 00:21:25,076
lt is??

331
00:21:25,160 --> 00:21:28,596
Of course it is£¡ We had a few problems at first
but...

332
00:21:28,680 --> 00:21:32,912
But where would we all be if no one ever made
a mistake, right class?

333
00:21:33,080 --> 00:21:34,559
Right Ms Frizzle£¡

334
00:22:05,000 --> 00:22:08,072
You know, Liz, l'm glad we did the Computer'
show.

335
00:22:08,160 --> 00:22:11,630
l mean, how often do you get to see how a
computer works from the inside?

336
00:22:11,760 --> 00:22:14,672
Hey, do you think that thing could get me a cup
of coffee?

00:22:17,720 --> 00:22:19,836
Magic School Bus, the producer speaking.

338
00:22:19,920 --> 00:22:22,070
Hi£¡ l just watched your 'Computer' Show,

339
00:22:22,160 --> 00:22:23,115
and l was wondering,

340
00:22:23,200 --> 00:22:26,636
can you really see the information travelling
around inside a computer?

341
00:22:27,280 --> 00:22:28,679
l wish you could -

342
00:22:28,760 --> 00:22:32,196
but the information gets changed into
electronic signals that are invisible.

343
00:22:33,680 --> 00:22:36,956
So how come we saw the information as
flashes of light?

344
00:22:37,120 --> 00:22:40,351
lt was our way of making the electronic signals
visible.

345
00:22:40,440 --> 00:22:43,079
And then we slowed them down so the kids
could follow them.

346
00:22:43,560 --> 00:22:47,269
So is the fact that electrical impulses travel so
fast

347
00:22:47,360 --> 00:22:49,749
why a computer can follow instructions so
quickly?

348
00:22:49,840 --> 00:22:51,034
Right as RAM£¡

349
00:22:51,200 --> 00:22:53,191
The computer can read information

350
00:22:53,280 --> 00:22:57,239
faster than you or l could read it - or type it - or
even think it£¡

351
00:22:57,320 --> 00:22:59,231
Okay, l buy all that -

352
00:22:59,320 --> 00:23:02,278
but can you really make a computer do jobs
like the kids did?

353
00:23:02,760 --> 00:23:06,469
Sure£¡ Since computers can turn switches on
and off,

354
00:23:06,560 --> 00:23:09,836
anything that can be run by a motor can be run
by a computer.

355
00:23:09,920 --> 00:23:13,879
Although, there are a lot more steps to running
a program than we had time to show,

356
00:23:13,960 --> 00:23:15,313
the idea is the same.

357
00:23:15,400 --> 00:23:18,790
You give the computer instructions through the
keyboard or floppy disk...

358
00:23:18,880 --> 00:23:23,237
...the CPU in the motherboard makes
decisions based on the instructions...

359
00:23:23,320 --> 00:23:25,550
...and the computer stores them so it can use
them

360
00:23:25,640 --> 00:23:27,073
over and over as needed.

361
00:23:30,240 --> 00:23:34,199
But the inside of a computer is a lot more
complicated than the one you showed.

362
00:23:34,280 --> 00:23:38,910
Yes, but the parts are all basically the same -
disk drive, motherboard...

363
00:23:39,000 --> 00:23:43,118
CPU...hard disk... Thanks - l get the picture.
Bye£¡

364
00:23:44,280 --> 00:23:45,076
Bye£¡

365
00:23:46,560 --> 00:23:50,473
Oh, thanks, but l don't really want it anymore...

366
00:23:52,360 --> 00:23:53,315
Joke£¡

367
00:23:56,240 --> 00:24:00,552
Mmmm£¡ That computer makes a great cup of
coffee...£¡
