Journal 1
Jan. 2nd
This is the first day of the class, web technology & network management. My professor is Dr.Ebrahimi, and he is a very kind man.
First we briefly studied the requirements for this course: Collaboration, Team work, Class work and Journal.
Definitions:
*History of "www": world wide web, the complete set of documents residing on all Internet servers that use the HTTP protocol, accessible to users via a simple point-and-click system. It was developed at the European Organization for Nuclear Research in Geneva from a proposal by Tim Berners-Lee in1989.
Html stands for Hyper Text Markup Language that is the document format used on the web.
algorithms are problem solving steps that are needed to find a solution to a problem such as the shortest pash from one city to another or computering employee wage.We also learned how to evaluate an algorithm :time ,space .and cost.
Home work & Assignment: A. use a front page to type about myself,and save the file
B.make a yahoo account

What should we put in our web sites?
1. Journal of the day ( 80% material covered in class )
2. Assignments, ( projects and researches )
There is a quiz, a midterm and a final exam during the section.
Research: *What is Nanotechnology?
A branch of science and engineering devoted to the design and
production of extremely small electronic devices and circuits built from
individual atoms and molecules.
Project: * Redesign the following web sites:
1-
www.computerhumanerror.org
organization
2-
www.dalalmolk.com
real estate agent
3-
www.drebrahimi.com
Dr. Ebrahimi web site
4-

Dr. Ebrahimi web site
5-
www.pejohesh.com
International youth organization
6-

to be built
Network Management Project*:
What are the component of Network and what manager should know
1- How the role of the manager should be addressed?
2- what is a view source and technology?
Notes:
*The bit is the smallest element of computer storage. It is a
positive or negative magnetic spot on the disk and tape and charged
cells in memory.
Byte (Binary Table): The common unit of computer storage from desktop
computer to mainframe. It is made up of eight binary digits (bits). A
ninth bit may be used in the memory circuits as a parity bit for error
checking. The term was originally coined to mean the smallest
addressable group of bits in a computer, which has not always been
eight.
1 megabyte= 1,024 kilobyte 1 gigabyte= 1,024 megabyte
*Can computer be in fuzzy state?
Yes. Because there is a context, for example, mild, hot, very cold.
Fuzzy logic means it has more than two states.
Computer is in a binary state because it is easy. There is a current
and no current.
Can computer be on octal state? Yes, but it is not easy.
There is no context in computer.
URL does not have a blank in it.
*ASCII:
(American Standard Code for Information Interchange), generally
pronounced
[ˈæski], is a
character encoding
based on the
English alphabet.
ASCII codes represent
text in
computers,
communications
equipment, and other devices that work with text. Most modern character
encodings have a historical basis in ASCII.
ASCII was first published as a standard in 1967
and was last updated in 1986. It currently defines codes for 33
non-printing, mostly obsolete
control characters.

NOTE
In every web
page contains a tag HTML and end with HTML
the ten
commandment covers 90% of the HTML the web design
Everyone must create ten files for each and include the previous tag that
you have learn
* you can use
anchor to link to another page out of your directory (web site) and also a
page under your directory
The administrator does not allow you
to save to the C: drive, but you can store to your network drive which is
the H: drive where you can access your information anywhere on campus, not
off campus
Today in class we covered a few common known but very important topics that
we all should know for everyday life about computers. We discussed the
importance of saving your files and emailing them to yourself because it can
be accessed anywhere, no matter where you are. It also acts as a duplicate
just in case the main file on your computer goes missing or your computer
stops working, it is still accessible from any other computer with internet
access. Another place to save a file in order to access it anywhere is to
save it on a flash drive, or a USB storage device. This is a portable device
that you can carry around with you with most of the important information.
On our campus we are able to only save on the H: drive but once saved, that
drive can be accessed anywhere on campus because the campus is on its own
network. The network manager only allows the H: drive to be used by us and
not the C: drive because they are scared that we save viruses on it. Work
for this class should be saved on geocities because it can be accessed
anywhere with internet access.
We
also learned what the ACM stands for and that is association for computing
machinery and they gives direction to the computing field. We also learned a
little about the ASCII code and we learned that letter "A" has a code of 65
and letter "a" has a code of 97. We briefly spoke about what nanotechnology
is and we know that nano is 1 billionth of measurement
today is my birthday,I'm 22
years old now.

on internet, not everything is true, you need to research it to see if it is correct such as wikipedia
PROGRAMMING ERRORS and their cost Y2k, space shuttle, prescription drugs, hospital
Nano-technology impact on business future growth or declined and research cost by US gov. and others such as European, Japanese, Chinese
working with host and front page Obstacle Technology changes rapidly but the tools are very the same (good or bad)
2) Every software has an error: Evaluating the web pages of different colleges and university.
3) new topic what is programming
6) accessed wikipedia to learn about history of and how anyone can edit its word meanings, can't entirely trust it
FIRST QUIZ WILL BE ON FRIDAY, EACH STUDENT MAKE UP 10 QUESTIONS EACH TO BE ON TEST.... 100 TRUE/ FALSE QUESTIONS ON COMPUTER, OPEN NOTES, OPEN INTERNET ACCESS, BUT NO COMMUNICATION. PLEASE SUBMIT BY EMAIL TO PROFESSOR ON THURSDAY BY 12:00PM TO PROFESSOR EBRAHIMIDR@GMAIL.COM. QUESTIONS SHOULD COVER 8 DAYS WORTH OF MATERIAL FROM JOURNAL ENTRIES AND TEXTBOOK. 8 FROM THE CLASS, 2 GENERAL KNOWLEDGE.
FOR INSTANCE THE CAPITAL LETTER OF A IS 32? T/F
ASCII CODE IS WAS AN AGREEMENT BETWEEN PEOPLE TO BE CARRIED ON BY EVERYONE

What does Wiki the root mean? It is a Hawaiian word for quick ,it not a trustable web.
Today is it is not necessary to use light bulbs or vacuum tubes to represent the states of on/off. Other means such as electrical currents or magnetic fields are commonly used to represent these two states which we call binary states. You may be wondering why there are two states rather than 3 or more? One answer would be that it is easier to manipulate and work with binary representation. If it were not in the state of one then it would be in the state of zero, you may then ask why only use zeros and ones instead of other numbers such as 1, 2, or 3. While you can represent characters that way to but using zeros and ones make it easier. Some other possible binary state representations can be that if there is a current or not, magnet or no magnet, light or no light, hole or no hole. Perhaps future computers can use biological entities such as a cell's DNA sequence or binary state representation. As switches have on/off states, the cell can also have 2 active and inactive states under certain circumstances. Imagine millions of microscopic spots (binary states) on a piece of board that could be grouped to form characters, words, and sentences, which thus comprise information. P. 4 in text.
How do you represent number 2 in the binary system. (We are working with decimal system (0...9) in our daily life)
How do you represent number 10 in decimal system?
Ebrahimi believes we are working with decimal system because we have 10 fingers, if we had 16 fingers we would be working with the hexi system, or if we had fists we would use binary system.
bi - 2
octi - 8
deci - 10
hexi - 16
According to our classmates, letters don't represent each letter like English language, its the way it sounds it forms symbols such as Al i.
How much is 1 + 9 = 10 How do you represent it? We don't have representation from 1 + 9 in our decimal system, as a result we represent it with a zero with an indicator that we have gone through the system once and call it "carry over"
+ 5 if you know the answer
How much is 9 + 1 in decimal system? Last digit 9
How much is 1 + 1 = in binary system? Last digit 1
How much is 1 + 7 = in octal system? Last digit 7
How much is 1 + f in hexa system? Last digit f
Today we learned the science of color R G B
how many colors would you have from 000000 to ffffff each symbol has 16 variation and think of 16*16*16*16*16*16

Today's
topic is server.
Tomorrow
we are going to have the first quiz. Everyone is supposed to make 10
questions for the quiz.
