Home Computers

Some students decide to purchase a computer while
taking this course.

Since you have computers available to you at the
labs, it might be advisable to wait until later in the
course, when you have more experience and
information about your options.

You do need to be prepared to spend lots of time in
the computer labs or on your home or business
computer to do the homework for this class.
Assignments








There will be nine assignments. Home work will be worth
50% of course grade
Be prepared to spend 10-20 hrs per week to work on
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.
However, late assignments will be severely penalized, and may
not be graded except to note that the assignment was turned in.
Assignments that you turn in should be your own work.
It is fine to talk to other students and to get assistance in how
to do something, but you should not ask your fellow students
to actually do the work for you.
Cheating will NOT be tolerated!
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
If you are caught cheating, you will receive an immediate
FAILURE for the course.
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

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!
