Principles: Exploring concepts behind computers,
Networking, and Internet and the web



The development of computer technology is one of the great stories of the Twentieth
Century.
An educated citizen should know about computers.
We will tell you something about:
 Computing Hardware
 History of computing, Internet and the web
 How the Internet and the web work
 Copyright, privacy, security, etc..

Current developments in the world of computers and the Internet
Software used for this course





Course Materials





Please note:
As this is a course about technology, we will provide
on-line resources on all of the subjects that we
cover.
However, we are aware that for some of you, it is
easier and more convenient for many reasons to
use textbooks.
In such a case, here are the textbooks that we
recommend for any and/or all of the topics that we
plan to cover.
Please be sure to speak to us if you have any
questions about the readings.

Administrative issues
Using the computer facilities






Because you have registered for this course, you will be able to use the
computer labs at any time they are open.
The lab will have all software need for this class and you can use
during this course
You need to use your ID card to gain access.
The main computer labs that you will be using is in the (Apple
Computers):
1. Multimedia lab
Education Building
35 W. 4th Street
on the second floor.
2. Third North Dorm
3rd ave. and 12 street.
Tutors will be present at Third North lab 20 hours a week. Tutor
hours will posted on course homepage
There are other labs, although those are the main two with Apple
computers.
Internet Account and class account used in this course
Special UNIX Account called “I5”:
 used for developing your web site
 You do NOT have to apply for this account, you will be
assigned this account automatically based upon your
enrollment in this course
 If you are a high school student, please speak to me today
to set you up with an account. You will not be able to do
it on your own.
Assignments


* Please note that in this class, it will be acceptable to do your
assignments on a Mac OR a PC.
Notes on the assignments:
 In all, there will probably be about eight assignments.
 It is important not to get behind in turning in
assignments.
 If you do get behind, we still want you to do the
assignment, so it is better to turn in a late assignment
than to skip it and you may wish to speak with your
instructor about this.
 However, late assignments will be penalized, and may
not be graded except to note that the assignment was
turned in.
Late assignments are penalized as follows:






10% during the first week late;
20% during the second week late;
and 30% during the third and fourth weeks after the due date.
Assignments due before the midterm exam are not accepted after the
week after our return from spring break without special permission from
the instructor.
No assignments are accepted after the last day of class.
Extensions:
 You are permitted one extension (for one week maximum )
no questions asked! - during the course of the semester.

You need to email grader notifying her about extension before
assignment due date.
- However, please do not hesitate to contact me if you are falling behind, if you
would like assistance, or there are circumstances beyond your control which
delay your work.
A Word About Cheating

For the purposes of this class, cheating is defined as:



Copying all or part of another student's homework,
project or exam.
Allowing another student to copy all or part of your
homework, project, or exam.
Discussing homework concepts is fine, but you
must submit your own work
• Make sure to read the CS department statements on Academic
Integrity for more details.

If you are caught cheating, you will receive an immediate
FAILURE for the course.
Save copies and back-up your work
(use a USB flash drive).





For your own good you must save all programs
on back-up storage medium.
Lost work or crashed systems do not provide
adequate excuses for missing or late homework.
You might consider purchasing a USB Flash Drive that you can
easily carry around especially when you want to work in the lab.
 These have become very cheap.
You could also store all of your assignments and course work
under your NYU Home Account.
So, one option is to upload your files online and download them
as needed (we will go over this in class).
Student Civility

In an effort to make this class enjoyable for
everybody…
 Please be on time to class!
 Please do not talk to your friends and
neighbors in class!
 It disturbs everyone, and makes it hard to
concentrate.
 If you have a question, just ask me!
 Please turn your pagers and cell-phones off!
Exams and Grading
 Grade Distribution:
 Assignments (50%)
 Midterm exam (20%)
 Final exam (30%)

What is a Computer?



Computer
 Device capable of performing computations and making
logical decisions
 Computers process data under the control of sets of
instructions called computer programs
Hardware
 Various devices comprising a computer
 Keyboard, screen, mouse, disks, memory, CD-ROM, and
processing units
Software
 Programs that run on a computer
Computer Organization

Six logical units in every computer:
 Input unit
 Obtains information from input devices (keyboard, mouse)
 Output unit
 Outputs information (to screen, to printer, to control other devices)
 Memory unit
 Rapid access, low capacity, stores input information
 Arithmetic and logic unit (ALU)
 Performs arithmetic calculations and logic decisions
 Central processing unit (CPU)
 Supervises and coordinates the other sections of the computer
 Secondary storage unit
 Cheap, long-term, high-capacity storage
 Stores inactive programs
Personal Computers



Personal computers
 Economical enough for individual
 Popularized by Steve Jobs and Steve Wozniak with the
introduction of the Apple in 1977.
 In 1981 IBM introduced the IBM personal computer using
“off the shelf” components.
Distributed computing
 Computing distributed over networks
Client/server computing
 Sharing of information across computer networks between
file servers and clients (personal computers)
History of the Internet




In the 1969, the Advanced Research Projects Agency of the
Department of Defense (ARPANet) funded research to
network its researching facilities and universities
Packet switching
 The transfer of digital data via small packets
 Allows multiple users to send and receive data
simultaneously
No centralized control
 If one part of the Internet fails, other parts can still operate
Bandwidth
 Information carrying capacity of communications lines
History of the World Wide Web

The World Wide Web (WWW) was created in 1989/1990 by Tim Berners-Lee

Allows users to locate and view multimedia-based documents create
by others in the world on various subjects
 files, images, animations, video, audio, etc.

An Internet Browser ( such as Internet Explorer or Netscape) is a
software that allows you to browse the Internet and view/download
documents from the web

Possible for individuals and small businesses to get worldwide exposure

Changing the way business is done (yes, this is still true in post bubble days)
Good luck!
