lesson 1:
1. What is the name and age of one of the oldest calculating machines?
One of the earliest was the abacus. It’s about 5,000 years old. Mechanical calculators that could add and multiply (but not subtract!)
2. When were mechanical calculators invented?
mechanical calculators were invented in the 1600s.
3. Who invented the "first" true ancestorial computer? When was this? Did it work?
Charles Babbage invented the ‘’first’’ true ancestorial computer, this was in the 1800s. yes this worked, but today this things are working better.
4. What allows today’s computers to do computing that wasn’t possible 200 years ago?
todays computers are allowed to do computing was the invention of something that could do calculations and other information processing with no moving parts and do it very fast. That something was electronic components. With electronic components, a fast and efficient machine , this wasnt possible 200 years ago.
6. What are the four parts of a computer?
input(The data that is entered into a computer. The act of entering data into a computer), storage(In computing, any device in which (or on which) information is stored), processing(The manipulation of data by a microprocessor or embedded processor according to instructions given to it by a program or embedded in the chip itself) and output(The computer generated information that is displayed to the user in some discernible form such as a screen display, printed page, or sound
lesson 2:
1. What are the physical parts of a computer called? the keyboard and the mouse, these are called hardwares.
2. How is input processed by a computer? you can’t touch software, it gives te computer the ability to process many types of information!.
3. What is the job of a microprocessor? device in the computer that performs mos of the task we ask the computer to do.
4. Again, what are the four components of a computer? the four components are input, storage, processing and output.
5. Do the Lesson 2, Activity 1: Which Does What? cd-rom drive: storage, floppy drive: storage, hard drive: storage, motherboard: the circuit that works on input, storage, processing and output,.
lesson 3:
1. Define information processing - means to be able to accsess a computer and change information etc…!
2. What kind of information is processed these days? adding things deleting them or rearenging.
3. Define input - input devices are used to put information into your computer, the mouse is also considered an iput device.
4. What devices do we use today for entering information?Some device we use are for example: You type information in the keyboard and it appears in the computer. You speak into a microphone and the computer gets the words. You can put the video camara and someone can see you and put funny faces. Also the mouse is an input device.
5. How was information entered in the early stages of computers around 1945? it was used in a computer that could only type used with paper, the keyboard typed into the paper.
6. What was this first computer called?The first computer was called The Analytical Machine, the first punch-card programmable general-purpose computer.
lesson 4:
1. What 2 kinds of information do computers store? computers store any information thay you wirte yo give or yo save in it the computers recieves it as instuctions.
2. Which memory stores temporary information? it is called the temporary information system.
3. Which memory stores long term information? it is called long term memory (information from the past)
4. Is RAM stored once the computer is shut off? if someone is working and they shut off there computer the operating system is not stored in ram.
5. Can the data on ROM be changed?no.
6. What other 3 types devices are available for storing information? the hard drive, pen drive,(disco duro).
7. What material are hard drives made of? non - magnetic material, ussually glass.
8. How many megabytes of information can be stored on a cd-rom? 1000 gb.
9. Why are floppy disks called "floppy"? because when you wave a floppy disk it flops.
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?
lesson 5:
1. Where does all data and instructions pass through in the computer? through the computers memory and a pass-through.
2. In what decade could all the processing functions be put onto a single chip? in 1583 or the 20th century.
3. When did Intel invent the first microprocessor? in november, 1971.
4. What kind of chip is used in DVDs, remote controls, and electronic calculators? And what makes this chip different from microprocessors? the chips in that devices are emmbeded proccesors, you cant change what they. microproccesors are much more versatile than emmbeded proccesors.
5. What is the advantage of microprocessors? that they are much more versatile. they are designed to do whatever the software you select instucts them to do.
lesson 6:
1. What is output, give three examples: computer speakers, mp3 files and thing printed from ure computer etc…
2. What 3 steps does the microprocessor handle? it carries out instructions, performs calculations and interact with the components used to operate the computer.
3. What is the difference between download and upload? when you download, you download something from the computer and when you upload you import soemthing into youre computer files.
lesson 7:
1. What advantages do computers have over humans in the game of chess? computers are electronics and humans have cells.
2. How many times faster can a computer make a computation? 5 times faster…
3. How much more data can a computer store? 256gb
4. In what sense are humans a lot smarter than computers? humas design computer, humans show comppasions (feelings) etc…
5. If a computer was able to have original thought what would this be called? it will be called artifical intelligence.
6. Do you believe computers will ever be able to develop beyond humans? no because humans are the ones who invent the computers hehehe..!
