4-Technical Understanding

(1) History of computers / graphic search engine

Answer the following questions using information from technology education websites or other online resources. Make certain that all information is in your own words. No credit can be given for information that is identical to that of another student or a web page.

  • Contributors to the development of the computer: Select five individuals who have made significant contributions to the development of the computer. List the contribution(s) of each individual and briefly describe its importance. See technology education websites. Use a graphic search engineto find pictures of each.
  • Computer Generations: Computer historians have classified computers into "generations" in an effort to identify the major technological advances upon which the computers are built. Briefly identify the major features of each of the first five generations of computers. See technology education websites. Use a graphic search engine to find pictures of each.


I have created a handout for assignment 1.1. For this assignment I chose to focus on early contributions to the modern computer. The handout is shown below and can be accessed on Google Drive directly from the viewer as well.

Contributors to the Development of the Computer


I created a similar handout for the computer generations:

Generations of Computers




(2) Computer knowledge

Teachers should be conversant with computer terminology and concepts that pertain to the use of technology in their classrooms.

  • Take the following online quiz. You can use any resources you like to answer the questions. Include a screen capture of your certificate showing your grade. You may take the quiz repeatedly if you like. Note: This test was generated at ProProfs.com . You will be given the opportunity to construct your own online quiz in the assignment on management.

I got an A on this quiz though I was caught by one or two that I should have gotten correct! Also the last question is based on a youtube video that is no longer posted. Below is a picture of my certificate:

(3) Computer profile

The market for personal computers is very competitive, and manufacturers are continually working to develop better and more powerful systems. Unfortunately, you can not determine how powerful a computer is by looking at the outside. It is necessary to look at the system profile to determine the type of processor, memory, hard drive capacity, etc. Compare the system profile of the computer used in class with your computer at home on the following properties. You may want to refer to eHow or your OS Help menu to determine how to find this information on your computer.

  • Compare the computer you use in the laboratory with the computer you use at home or work with respect to the following properties:
    • Processor: (a) name of processor; (b) number of processors; (c) processor speed
    • Memory: (a) how much RAM; (b) speed of the RAM (how many MHz)
    • Storage devices: (a) how many hard drives; (b) capacity of hard drives; (c) number and type of optical drives; type of hard drives (Firewire, USB, etc.)
    • Operating system: (a) OS; (b) service pack or version
    • Monitor(s): (a) resolution; (b) video card

Here is a comparison of my home computer and the lab computer:

Processor: 
(a) name of processor; 
    home: Intel Core i5
    lab: Intel Core 2 Duo
(b) number of processors; 
    home: 1
    lab:1
(c) processor speed
    home: 2.66 GHz
    lab: 3.06 GHz

Memory: 
(a) how much RAM; 
    home: 4GB 
    lab: 2 GB
(b) speed of the RAM (how many MHz)
    home: 1067 MHz DDR3
    lab: 800 MHz DDR2

Storage devices: 
(a) how many hard drives; 
    home: 1
    lab: 1
(b) capacity of hard drives; 
    home: 999.9 GB
    lab: 465.76 GB
(c) number and type of optical drives; type of hard drives (Firewire, USB, etc.)
    home:  USB:4, Firewire:1, Ethernet:1:, DVDCombo:1, SD:1
    lab: USB:4, Firewire:1, Ethernet:1:, DVDCombo:1,

Operating system: 
(a) OS; 
    home: Mac OS X
    lab: Mac OS X
(b) service pack or version
    home: 10.6.8
    lab: 10.5.8

Monitor(s): 
(a) resolution;
    home: 2560 x 1440
    lab: 1920 x 1200
(b) video card
    home: ATI Radeon HD 4850
    lab: NVIDIA GeForce 8800 GS

(4) Navigating the Internet

A Uniform Resource Locator (URL) is the unique address which identifies a resource on the Internet for routing purposes. Know how to interpret URLs.

  • Use a web-based traceroute program to trace the route between your computer and and a website outside of the United States. Include a screen shot showing a map and the text of the specific route taken when contacting the website. Compare your findings with those of others in the class. Are websites always located in the country in which they are registered? What does this show about the nature of Internet-based business and commerce? Traceroute programs can be used to track and graph web traffic to specific sites.
  • Compare the connection in the CSUN laboratory with your connection at home or school. What are the IP addresses of the computers you are working with? What kind of connections are your working with (dial-up, DSL, cable, 100-Base TX (twisted-pair LAN), 100-Base FX (fiber LAN), etc.)? Compare are your connection speeds.
  • Most schools have developed Acceptable Use Policies (AUP) and have installed filters to keep student focused on education. Include text (scan or download is easiest) of your school's AUP and a description of the filters in place. If a school AUP is not available, provide a sample AUP, cite its source, and provide a link. If your are not working in a school, summarize how filters work.

I used a web-based traceroute program to see where the Italian tourism website is hosted. It is hosted in Rome. Both traces took the same number of hops and took the same route: LA to Milan to Rome.
Using the IP address finder I found the IP addresses for the computer at CSUN that I have been using:

And the IP address for my computer at home:
It looks like my computer at home's internet connection is slower than the connection in the computer lab. It maybe because of the type of connection CSUN has a T3 connection and I have the lower level time-warner cable connection. It also may be the difference between a hard-wire connection in the computer lab and my wireless connection to the router two rooms away at home. 
Campus Connection speed:
Home connection speed:
According to all of the internet sources I found such ast this article from itquotes, the difference between T connections and cable are significant. T connections have a direct dedicated connection to the internet while cable is shared among many users and connection speed is variable. The difference between the internet speeds in the lab and mine at home is expected.

AUP: As for the Acceptable Use Policy, Gardena High (the school I profiled) does not have a AUP that is tailored to their campus posted anywhere. Thus, I have found the general LAUSD AUP and posted a link below:
