1.
Who
was Charles Babbage and what was his contribution to computer technology? What
did he invent and what was it designed to do? How did the Countess of Lovelace
help Charles Babbage and what was her full name? Were there any other machines
used before Charles Babbage's invention? Describe some and discuss what they
did?
Charles
Babbage was an English mathematician, and considered as the “father of
computer”. In the 1800s he developed two machines that laid the foundation for
computers as we know today. He
designed the “difference engine” and the “analytical machine” both meant
to do calculations.
Charles Babbage machine was the first one to have a program written for
it.
Countess
of Lovelace known as Lady Ada Byron Lovelace is considered as the first
programmer because she wrote a computer language program for Babbage’s
analytical engine.
There
were other inventions that led the pathway for the development of computers
before Babbage’s inventions. Abacus
was developed during the Chinese dynasty in 2600B.C is considered as the first
calculator. It was used for
addition and subtraction. After
abacus came Napier’s rods, which was capable of not only addition and
subtraction but also multiplications. Then,
there was Pascal‘s mechanical adding machine, the first gear driven
calculating machine. Mechanical
adding
machine was followed by Jacquard’s holes punched card machine which Babbage
based his designed of the steam powered engines.
2.
Define and list 3 examples of the term, input.
Input
in terms of computers means the computer components that are used to enter data
or information into the computer systems. Three
examples of input are keyboard, mouse, and microphone.
3.
Define and list 3 examples of the term, output.
Output
in terms of computers means the computer components that is used to display data
or information from the computer systems. Three
examples of input are monitor, printer, and speakers.
4.
Define and list 3 examples of the term, storage.
Storage
is the ability to keep data or information in a specific location.
Storage can be on hard drives, Internet, disk drives.
5.
Define and list 3 examples of the term, processing.
Processing
is analyzing input data and output out the result.
6.
Describe information processing as it relates to input in a computer.
Information
processing in computer entails data being inputted through the input devices and
the information is routed to the CPU- central processing unit which is
considered the “brain” of the computer.
The CPU controls all the traffic inside the computer and then sends the
input data to the proper station to be processed then to the output device
necessary to display the processed information.
7.List
and describe the 3 kinds of storage used by a computer.
There
are hard drives, compact disks, and floppy disk.
The hard dive is inside the computer and it provides storage for items
that you have had in your computer’s memory.
A compact disk is used to store information on a round disk.
Initially information stored on CD is considered permanent and cannot be
altered, but new re-write cds are now on the market. The floppy disk is another disk devise use to store data on a
computer. The floppy is widely used
but its storage space is very limited especially if one is storing graphic
files.
8.How
do microprocessors differ from other chips? How do they
work?
Microprocessors
differ from other chips because as an integrated circuit it not only contains
electronic circuit, but also memory storage for a computer. It contain, logic, arithmetic and control units necessary for
the operation of a computer. Microprocessors
contains circuit pathway upon which electricity signal flows throughout a
computer.
9.
How do software and a microprocessor work together when a computer outputs
information?
When
data is input in a computer the information is sent to the CPU by the electrical
signal of the microprocessors. Then,
it is directed to the proper software for processing.
After processing the signal sends it back to CPU, which then directs the
data to the right output media.
10.
Which is "smarter," a human brain or a computer?
No
contest…THE HUMAN BRAIN
who
developed the computer to begin with!!!
Things to try in TAPPED IN
Remember TAPPED IN is a large building, with an
inside and lots of rooms
and an outside with a woods and meadow to explore. Type HELP Movement
when you are logged into TAPPED IN to learn more about getting around in
the building.
Here are some things to try in TAPPED IN once you know the basics. The
tasks below will help you to understand more of what TAPPED IN has to
offer. Check these off as you do them:
1. Go to the Math Forum Suite (hint, it is on the
2nd floor): If you
are interested in teaching math, or multiple subjects in elementary
school you should know about the Math Forum. Find out what The
Collection is all about.
2. Go to Reception and then go "outside"
TAPPED IN. Go South, then west
then south again and explore the mating territories area. Imagine
learning about animals this way. What is your reaction? Did you find
the frogs? (You may have to look for them a bit, think about the
kind of habitat frogs might prefer, and remember not all frogs live
in ponds). What are the frogs` names? (Think about environments you
could build and ask us for more information about building in TAPPED
IN).
3. While you are "outside" of TAPPED IN
visit the student activity
center. What other things we should put in here? Did you know that
teachers can bring their K-12 students to TAPPED IN? We have special
student accounts for kids that teachers can obtain. Read more about
this at http://www.tappedin.org/info/classroom.html.
4. Visit the After School Online Room and look at
the different
resources there. Look at our archived transcripts. We have sessions
on different topics in TAPPED IN each week. Visit our events
calendar to see the current schedule.
5. Click on the SUPPLIES in the top right hand
corner. Look at the list
of virtual objects. If you are a member (not a guest), you can get
an items by clicking on them. There are many cool objects to get
from Supplies. What did you get? Extra hint: when using your object,
be sure to put a / mark in front of commands. For example, if you
get a dog, type /pet nameofdog.
6. If you are logged in as a member (not a guest),
try this: Click on
"new note" in the graphics area and create a note. Give it a name
and write a message on the note. Click on SAVE. Type /show
Nameofnote to PERSON to show it to one person or type /PROJECT
nameofnote to show it it to the whole room. What feedback or
response did your note generate?
7. Click on MY ITEMS and then click on your note.
Click on EDIT. Add a
URL to the note of a favorite educational website. Write a few
comments about the URL on the note. Click on SAVE. Then type
/project Nameofnote. Did the URL pop up onto the screen?
8. Check out the Office Directory in the 3rd floor
Lobby. Then click on
What's Here. Click on the Hot Coffee and pour yourself a cup of
coffee while you're looking around.
9. Find Kari's office (hint, it's on the 23rd floor)
and leave the note
you made earlier (about a great education website) in her office. To
leave the note, go to her office and type /drop NameofNote. Click on
UPDATE and look for your note under What's Here.
10. Locate one of your colleagues (e.g., classmates)
in another room by
clicking on Who's Online. Click on their location and you will
"teleport" directly to where they are. Who did you join? Where were
they?
11. Take turns playing Follow the Leader - follow a
classmate to
somewhere in TAPPED IN they thought was interesting. Have them
follow you. Where did you go? What did you think of where you were
taken?
12. Click on CAMPUS MAP at the top of the screen.
Click on Main Library.
This will "teleport" you directly to the Library. Click around on
the various resources you find there. Find anything interesting?
Know of some good resources that we could add? Email
[email protected] and let us know!
