Before You Begin this Lesson
Please make sure you have read the course syllabus on this Web site. In it, please note the course schedule and how the readings, HTML exercises, and assignments have been allocated. The syllabus also outlines how you are to proceed through the lessons.
Objectives
This lesson will provide you with the opportunity to investigate basic communication technologies, how information is encoded, and how information is transmitted over short distances known as a Local Area Network (LAN). We will also learn a new and very important HTML command: the image tag. It is expected that you will use previously learned HTML commands and practices and that the new commands will build towards subsequent lessons in HTML.
When you have completed this lesson, you should be able to:
Explain the components of basic communication technologies.
Use an example to illustrate the encoding that occurs in character and digital information. See your 60-104 notes for details on binary to decimal conversion, decimal to binary conversion and ASCII code conversions.
Describe error detection and correction.
Describe how parity bits and checksum techniques are used.
Explain what is needed to create a Local Area Network and outline the advantages of a LAN.
Give examples of the functions and features of a common FTP program (see Assignment #3).
Create a simple Web page using the image tag and its attributes: alt, border, align, height and width (HTML Practice Exercise #4).
Create a simple Web page using the aforementioned image tag with the anchor tag.
