Student Introductions

• Tell me about yourself– Work experience– Current employment– IT Background– What kind of computing resources do you

have access to?– Rate yourself on a scale of 1-10 on your

Network+ type skills

-Classroom/Building orientation

• Bathrooms • Cafeteria and Smoking Area • Snacks - Anything in a package (soda, crackers,

granola bars, etc) is 50 cents • Anything not in a package (fruit, pastries, coffee,

when I do.  Try to keep it under 10 minutes

Cell Phone Policy

• Please set your phones to vibrate or mute

• I don’t mind if you answer your phone, but please take it into the hallway

• At end of class, shutdown your machine. Make sure it is OFF. The n, turn the key and remove the disk.

Expectations• Homework

– There is homework.  Consider this class "computer college" – If you don't do the homework, you will not pass your certs. 

•  Home Classroom – You need two computers with NICs and a switch/hub/router to

practice on.  – Needs to be breakable- Not the machine your

taxes/homework/Great American Novel are on – You can get these for cheap to free

• Attendance – Attendance is mandatory – Please sign in on the roster when you arrive – If you miss more than two classes you will not receive a

certificate of completion – If you're going to be late, please call me and let me know what

time you will make it so I can plan to start class accordingly – If you don't come to class, you will not pass your certs.

• Tutoring– Please ask for one-on-one tutoring outside of class if you need

help.– I want you to pass your cert.

Goals• What's your goal for this class? What are

your goals for intermediate future? • Goals vs Dreams • My goal is to get you certified.  • We’ll give you the tools: books, lectures,

Transcenders, PDF tests, answers to questions via phone and email, and hands-on training through labs.

• If you’re in this class, it means you probably already have your A+. If you have already passed one cert then you know what you need to do to succeed and you know that it’s possible.

Lab0 - Fix Computer Names and Join the Domain • Logon as “Administrator” - Password is “!Pass1234”• Restart the computer if it asks you to and log back in• Right click My Computer->

Properties->Computer Name->Change->  enter "Computer##"

where ## is the two-digit number assigned to your computer (i.e. Computer01, Computer02, etc.)

• Click “Member of” -> DomainEnter “Classnet” and hit OK

• Logon as User## where ## is the two-digit number assigned to your computer (i.e. User01, User02, etc.) with password !Pass1234

• OK….”Welcome to the Classnet Domain” - Restart

TCP/IPThe lingua franca of the Internet

A Very Brief History of TCP/IP and the Internet

• Origins of TCP/IP start in the 1960s at MIT and with the creation of ARPANET

• The original versions of TCP/IP as we know it today were created in the 1980s

• In 1983, the DoD mandated that all of their computer systems would use the TCP/IP protocol suite for long-haul communications

• ARPANET started with four nodes in 1969 and grew to just under 600 nodes before it was split in 1983.

• ARPANET grew smaller and smaller during the late 1980s as sites and traffic moved to the Internet, and was decommissioned in July 1990.

History of TCP/IP and the Internet (continued…)

• In 1986, the National Science Foundation (NSF) built a backbone network dubbed the NSFNET to interconnect four NSF-funded supercomputer centers

• Originally for non-commercial use, the NSFNET eventually became the backbone of “the Internet”

Dramatic Growth of the Internet

TCP/IP – What is it?• Transmission Control Protocol/Internet Protocol• A suite of communications protocols• TCP/IP uses several protocols, the two main

ones being TCP and IP. • TCP/IP is built into the UNIX operating system

and is used by the Internet, making it the de facto standard for transmitting data over networks.

• Even network operating systems that have their own protocols, such as Netware, also support TCP/IP

TCP/IP – What is it?• TCP/IP is roughly based on the OSI (Open

Systems Interconnection) Model

Math Review• Decimal – Base 10

– 0,1,2,3,4,5,6,7,8,9

• Binary – Base 2– 0,1
