Lesson Plan Overview:
Chapter 1 introduces the personal computer and a wide array of
other digital devices currently on the market, the digital
representation of data and the processing of data, and the security of
passwords. It starts from the ground up, and is designed to fill in gaps
in understanding for students whose knowledge may be spotty. It presents
a lot of terminology, and discusses the history of computers in the
context of this terminology.
Section A lists the major technologies fueling the digital
revolution. You will learn about the concept of convergence and
how it applies to digital devices. You will also explore some
ways in which digital technology affects society.
Section B offers an overview of computers, including
definitions of input, output, processing, storage, and the
stored program concept. You will learn the characteristics of
personal computers, servers, mainframes, and supercomputers. You
will also explore the similarities and differences in PDAs,
portable players, and smart phones, and learn the purpose of
microcontrollers.
Section C explains how computers represent data and
convert letters, sounds, and images into electrical signals. It
defines digital data representation, including binary number
systems. You will also explore the differences between bits and
bytes, and the technical meaning of common prefixes, such as
kilo, mega, and giga. You will receive an explanation of the
general concept of how 0s and 1s are handled by integrated
circuits.
Section D describes the relationship between compilers,
interpreters, object code, and source code. You will also learn
how a microprocessor's ALU and control unit work.
Section E is devoted to password security. You will study
examples of single-factor and two-factor authentication, and
they learn how hackers can steal passwords. You will also learn
the principles of creating secure passwords and keeping them
safe.
The Issue section of the chapter focuses exclusively on
tracking technology. You will learn about location-enabled
devices, global positioning systems, child-tracking services,
and RFID technology. This section discusses the spread of this
technology and the need for laws and regulations, as well as the
concerns of privacy advocates.
Computers in Context focuses on direct marketing attempts
to establish a one-to-one relationship with prospective
customers.
The Labs for this chapter give practice in operating a
personal computer, working with binary numbers, and
understanding the motherboard.
Because this chapter sets the foundation for working with a
computer, you should thoroughly understand the topics in each section
before you complete the lab assignments.
Lesson Plan Reading Assignment:
Read the following chapter:
Chapter one: "Computer and Digital Basics";
pages 2 through 41.
Lesson Plan Quiz Assignment:
Please take quiz in class.
Lesson Plan Lab Assignment:
Please see instructor for lab assignments in
class.
Discussion Question
Post a comment/answer, on the discussion board,
regarding one of the following questions:
1. Home computers are used more extensively than ever
for tasks such as banking, investing, shopping, and communicating. Do
you see this as having a positive or a negative impact on our society
and economy? Do you plan to use a computer in these ways? Why?
2. Describe your experience with computers so far.
Have you worked with (or played with) computers before? If so, why? Has
your past experience with computers influenced your decision to study
them?
3. Despite the rapid advancements being made with
handwriting-recognition software, do you think that the keyboard will
continue to be the preferred input device for generating text? Which
alternative--speech recognition or handwriting recognition--do you think
has a better chance of ultimately replacing the keyboard as the primary
device for inputting text?
4. Suppose that you are responsible for computerizing
a gourmet restaurant's order-entering system. What type of input device
do you think would work best for waiters to input orders to the kitchen?
You must post a comment/answer to any of the four
questions to receive credit for attendance for this lesson plan.
