Lesson 1 

1. What is the name and age of one of the oldest calculating machines?

Abacus is the name of the oldest computer , and it was invented in the 1600’s .

2. When were mechanical calculators invented?

Mechanical calculators were invented in the early 1800’s.

3. Who invented the "first" true ancestorial computer? When was this? Did it work?

Charles Babbage, it was a mechanical computer produced in the 1800’s it did not work , but todays computers are set up almost alike to his- Input, Data Storage, a Processor and Output.

4. What allows today’s computers to do computing that wasn’t possible 200 years ago?

Our computers are higher tech now , so they run way faster , and can hold much more capacity.

5. What was Stone Henge possibly used for?

The Stone Henge was a giant astronomical calculator , that was possibly used for astronomy.

6. What are the four parts of a computer?

Input, Output , Processor, Sotrage

Lesson 2 

1. What are the physical parts of a computer called?

Physical parts of the computer is known as hardware.

2. How is input processed by a computer?

Input is processed through the software in your computer.

3. What is the job of a microprocessor?

A microprocesser allows you to go play games, music, videos , etc , on your computer.

4. Again, what are the four components of a computer?

Input , Output , Storage , and Processor.

5. Do the Lesson 2, Activity 1: Which Does What?

Lesson 3 

1. Define information processing.

Information processing is the process where you can edit, save,or delete  hardware ,word documents ,etc on your computer.

2. What kind of information is processed these days?

Now a days the infromation that is being processed through our computers is Picutres, Videos , Games, Documents , Files , etc.

3. Define input.

Input is the component on your computer that allows you to store information on your computer.

4. What devices do we use today for entering information?

For entering information on our computer generally we would use a keyboard , but webcams , and microphones are used as well.

5. How was information entered in the early stages of computers around 1945?

Information would be stored by adjusting dials, punching holes in paper, and moving levers.

6.  What was this first computer called?

In 1945 this first computer was called ‘ ENIAC’

Lesson 4 

1. What 2 kinds of information do computers store?

The 2 kinds of information computers store are ROM and RAM.

2. Which memory stores temporary information?

Temporary information is stored by RAM.

3. Which memory stores long term information?

Long term information is sotred by ROM.

4. Is RAM stored once the computer is shut off?

RAM is stored temporarily while your computer is being shut off.

5. Can the data on ROM be changed?

Data on a ROM can not be altered.

6. What other 3 types devices are available for storing information? 

The 3 types of devices are known as Hard drives, RAM drives, and ROM drives.

7.  What material are hard drives made of?

Hard drives are made out of glass disks , or aluminum , then they are coated with ferromagnetic material and rotate around a central axle.

8. How many megabytes of information can be stored on a cd-rom?

On a cd-rom 640 megabytes can be stored.

9. Why are floppy disks called "floppy"?

Floppy disks are known as ‘floppy’ because they are made of very thin plastic. 

10. Try Activity 1: After you drag and drop the item it should say "THANK YOU… " if you are correct.

11. Try Activity 2: How many pieces of paper are stored on a floppy disk, a cd, a dvd, and a hard drive?

337 Pages are printed on a floppy disk, A hard drive is equal to 55,555 floppy disks, which is 18,750,000 pages of paper.

Lesson 5

1. Where does all data and instructions pass through in the computer?

All data and instructions have to pass through the processor.

2. In what decade could all the processing functions be put onto a single chip?

1970 , was the year that all computer functions could be stored onto a single chip.

3. When did Intel invent the first microprocessor?

Intel invented the first microprocessor in 1971.

4. What kind of chip is used in DVDs, remote controls, and electronic calculators? And what makes this chip different from microprocessors?

The chip that is used to store all that stuff is known as a Embedded Processor, this chip is different because they are only made to do one thing at a time.

5.  What is the advantage of microprocessors?

The advantage of micropricessors is they are much more versatile , and not made to do one thing at a time.

Lesson 6

1.  What is output, give three examples.

 Output is anything that comes out of your computer , for example sound , printers, and display screens.

2. What 3 steps does the microprocessor handle?

Microprocessor handles calculations , instructions, and operating your computer.

3. What is the difference between download and upload?

Downloading is recieving information from the Internet, Uploading is recieving the information from your computer.

Lesson 7 

1.  What advantages do computers have over humans in the game of chess?

Memory , speed , consistency, and it lasts longer.

2. How many times faster can a computer make a computation?

In one second a computer can make a computation.

3. How much more data can a computer store?

A computer can store more than a library , so therefore way more than our memory can store.

4. In what sense are humans a lot smarter than computers?

Humans can make smarter decisions, and computers are all the same , they dont have individuality.

5. If a computer was able to have original thought what would this be called?

That would be known as Atrificial Intelligence.

6. Do you believe computers will ever be able to develop beyond humans?

I think Computers have a good chance to develop beyond humans because humans use computers daily , and they are used at alot of jobs … but Computers can not take over our jobs , so therefore i think computers will not develop beyond humans.
