If you would like to view the video from the next slide from its original location on YouTube, please click the link below and either way please stop the video at 3:34. This

Note: The speaker talks low so make sure your volume is up.

• WAN’s are when several LAN’s are connected together.

• Key difference between a LAN and a WAN is that a company doesn’t own all the pathways between the computers = data has to leave the LAN area.

• (ie: Bank of America has several offices across the country that share data)

• LAN’s have several computers that are physically connected to one another via a central hub called a switch.

• LAN’s include a server and a shared printer.

• (ie: The Academic Skills Lab at ACC)

TWO TYPES OF NETWORKS

Local Area Networks (LAN) Wide Area Networks (WAN)

• Clients

• Servers

• Switches and Routers

• Connectivity

• Protocols

• Connectors and Ports

NETWORK COMPONENTS

RJ-45 cables

THE INTERNET

THE INTERNET

• World Wide Web (www)

• Is a collection of hypertext files, containing graphics, audio, and video that can be accessed on the Internet.

• Electronic Mail (e-mail)

• Uses its own protocols to route a message between computers on the Internet and hold it at a destination mail server until the recipient picks it up.

• File Transfer Protocol (FTP)

• Is an information workspace on the Internet. It is used for file transfer.

EMAIL ETIQUETTE AND COMPUTER ETHICS

• Etiquette – are the rules that govern courteous behavior, such as holding the door open for someone.

• When applied to emails, improper etiquette can result in serious misunderstandings and ill will among people.

• Ethics – are the moral principles that govern behavior. These are the rules we use to determine what is right from wrong.

• Ethics should be thought of when one thinks of copyright laws and piracy acts.

EMAIL ETIQUETTE AND ETHICS

WHAT’S MOODLE, ACCESS EMAIL, AND WEBADVISOR?

• In this class, we are going to use Moodle on a regular basis to submit your assignments.

• Also, communication with your instructor is key. The best way to contact me is via email (Access Email provided to you from ACC). I will send you emails every so often and it is your responsibility to check your email regularly. This is a good habit to get into in the Information Technology Age.

• WebAdvisor is a website that helps you register for classes, request transcripts, and is what I like to call the GPS for your degree/major.

• With that said, lets become more familiar with these websites

• First, lets set up your Access accounts if you have not done so already and log into WebAdvisor.

HOMEWORK #1

• Everyone make sure to turn in your Classwork #1 from today or it is due a week from today. Make sure to write your name on your sheet of paper to receive credit. No LATE WORK Accepted!

• Knowledge Check Questions pg. 28 in the Information Technology Essentials section of your book

• Write out the questions and then answer

• Complete numbers:
