Thought Questions
1. Would octal or hexadecimal be a better way to refer to the addresses in a 16 bit processor? Justify your answer.-
2. Relate the concept of program to the fetch-execute cycle of the Von Neumann machine.
- In the Von Neumann Machine to process. 'Input' as fetch-instruction.to start the cycle, the central processing unit then decode the instruction fetched. Arithmetic unit then get the necessary data to execute the decode instruction. This shows that fetch-execute is directly related to the Von Neumann machine.
3. Personal computers originally came equipped with one, then two floppy drives. After that floppy drives became optional as CD drives became an standard equipment. Now USB flash drives are the current medium for storage of data. What are the advantages of flash drives over other forms of disk storage? do you think they will replace other media?
- As the technology advances, several old device no longer able to keep up the demand of storage, life span and speed. USB have a long life span because it does not have a moving part in itself. Moving part mechanism is too slow in modern sociality. Therefore one day flash drive will have enough storage, speed and it's durability to withstand the demand replacing other kind of media.
4. Why don't we just use powers of 10 when referring to storage? Aren't powers of 10 and Powers of 2 close enough?
- Computer is all about accuracy and precision any mistake will cause huge problem to it therefore any computing must be the correct number, not only 'close enough'
5. Walk through your kitchen and list the number of items that include embedded systems.
- Since the house that I current live in have only a small kitchen area and I am not a cooking person, I have the only item that have an embedded system is my Electric water heater. When it is boiling it will automaticly decrease the temperature to warm.
6. Did you have computer in your home as you were growing up? If so how did it influence your education to this point? If not, how did the lack of a home computer influence your education to this point?
- I remember when I was a kid, my father did manage to put together a barely working computer for me to play around. I was very happy for such event so I grew up working hard for myself so I can understand computer more.
7. The digital divide puts those who have access to technology on one side and those who do not on the other side. Do you feel that it is the right of everyone to have access to technology?
- Technology do put people into sides, but I personally think that everyone have the right to have access to the open internet world. Then again people must respect those who have and don't.
8. It will cost a great deal of money to erase the digital divide.Who do you think should be responsible for paying the cost?
- It will be a great deal of money to do such big thing, but it is very possible in the near future. Since scientist and manufactures are able to have yearly breakthrough of technology leading to many new innovation, and it is getting cheaper month by month. So I believe in the near future it will cost fairly average to erase the divide. Carefully plan thing accordingly the project will be less costly awhile reaching the most efficiency.
9. Having access to technology is not enough people must be taught to use the technology they have, How would you define computer literacy for each of the following group of people?
Kindergarten teachers in an industrialized country.
- Teach them a little bit more then enough to able register, login and use certain equipment.
High school students in an industrialized country.
- To the point they are able to keep in line with their professor's e-mail and other requirement may necessary.
College graduates in an industrialized country.
- To the point they are able to have a general idea of any kind of GUI so in the future they can easily understand how to operate automatic machines
Students in sub-Saharan Africa
- To the point they are able to access information on the internet.
Government officials in the Audes
- To the point they are able to keep in contact with uppers and their co-workers
