Directions:
1. pair up into teams of two
2. Your team will randomly pick one IT Job out of a basket (see Mrs. Jordan for this)
3. Use the CIW Text and the internet to research the job you have selected
4. Create a PPT presentation to show to the class that covers the following areas:
1. Responsibilities / tasks2. knowledge / skills
CONDUCTING JOB SEARCHES Participate in on-campus interviews (college students)

JOB SEARCHES (CON’T) Traditional methods of finding jobs (classified ads, job fairs) are the most
common but least effective ways if finding employment (especially if you don’t combine them with any other methods)
You are better off combining a couple of different methods in your job search
Using Internet technology is the most effective way of getting information about different job opportunities
USING THE INTERNET TO CONDUCT JOB SEARCHES Use the Internet to get information about career opportunities in the IT
Industry
By entering keywords and narrowing your search you can find many job listings related to your personal career goals.
The following sites provide information about careers and have thousands of job listings:
www.dice.com www.monster.com
www.careerbuilder.com http://careers.yahoo.com
www.indeed.com www.guru.com
http://jobs.freelanceswitch.com www.allfreelance.com
www.sologig.com www.collegerecruiter.com
BUILDING A PERSONAL NETWORK The Internet provides a great opportunity for you to create and build
professional networks that may lead to job opportunities.
Some sites are already set up for you to build a professional profile. You can create a resume, list current and past jobs, skills and education.
Once you become a member of these sites you can create links (“friend”) with people that you have worked or associated with.
Users can also write and post professional recommendations for one another.
These sites are:
www.linkedin.com www.spoke.com www.zoominfo.com www.jigsaw.com
CREATING A RESUME You can use various text formats to create your resume
Your choice depends on the way you deliver your resume to potential employers
You can create a hard copy (print) or electronic format
Printed Resumes should be created on a word processing program (SM Office, Google Docs, OpenOffice)
Electronic Resumes should be created in plaintext, RTF, PDF, or HTML
TECHNICAL CONCEPTS AND TRAINING You can demonstrate a level of competence in specific IT fields by getting
professional certificates (CIW, A+, Network+, or Security+)

As an IT Professional you will have to translate highly technical concepts into information for a non-technical audience so your communication skills are very important
If you are a Help Desk Technician you have to troubleshoot problems and explain the solution to end users that may not understand
Think about people you know that have very few computer skills. How would you guide them through a technical problem?
JUSTIFYING IT RELATED EXPENSES As an IT Professional you must keep in mind the Return on Investment
(ROI) and its impact on IT decisions and how they effect your company’s bottom line. Are the benefits worth the expense?
EXAMPLE: as Lakeview Middle School students we are convinced that purchasing and assigning MacBook Air laptops to every student in our school would benefit student engagement and increase student learning. We create a proposal with all kinds of data and pricing for our Principal. We even get a petition going with thousands of parent and student signatures. But our idea gets turned down. Why?
TECHNOLOGY ADOPTION MODEL Paradigm Shift – a change from one way of thinking to another. Revolutionary
change. A paradigm shift can happen when new technology is introduced that radically alters the production process of a product. For example, the assembly line created a major paradigm shift not only in the auto industry, but in all other areas of manufacturing as well. Smart Phones created a paradigm shift in the way we communicate, research, and socialize.
Moore’s Law – the number of transistors per square inch on integrated circuits will double every 2 years. Video 1 - https://www.youtube.com/watch?v=bLSMn0cNWAw Video 2 - https://www.youtube.com/watch?v=aWLBmapcJRU
Technology Adoption Life Cycle – the rate which people adopt new products or technologies: Innovators, Early Adopters, Early Majority, Late Majority, Laggards

BUSINESS MODELING - ONOTOLOGY When discussing computer science and Web technology, ontology is the study of
how a particular part of a company, called a domain, is organized.
Ontology describes how individual elements of a domain relate to each other
The relationship is hierarchical
It helps programmers and designers tailor their systems to the needs of a business
They can successfully map out solutions for businesses and organizations
EXAMPLE: OCPS IT Department can design a system for users to login to the network based on their role within the organization. Tech Coordinator has more rights on the computer than students because of the job they
must do to provide, fix, and monitor technology on campus
Web Ontology Language (OWL) – various languages exist for defining ontological relationships. The Web Ontology Language is the most current.
DATA MODELING Determines the requirements that a database must fulfill in order to function properly
for an organization
When creating a data model you first create a conceptual model, which documents the data and information within an organization and how its used
The implementation of a conceptual model is called a logical model
When engaging in data modeling, you take the following steps: Planning and analysis – identify business requirements Conceptual design – creating the model as a pure concept Logical design – encoding the concept into SLQ programming Physical design – determining exactly where the data will be stored Implementation – applying the design to an actual database application, such as MySQL or
Oracle

INTERNATIONAL ORGANIZATION FOR STANDARDIZATION (ISO) 9000 National standards from 157 countries
The ISO develops technical specifications for intellectual, scientific, technological, and economic activities
ISO comes from the Greek word isos (which means equal)
Website: www.iso.org

WORLD WIDE WEB CONSORTIUM (W3C) Creates Web standards and guidelines
Created by Tim Berners-Lee and others
Mandates that the most fundamental Web technologies be compatible with one another and any hardware and software used to access the web must be able to work together (Web Interoperability)
Published more than 110 standards (W3C recommendations)
W3C doesn’t force manufacturer compliance as a result recommendations can be partially implemented

INTERNET ENGINEERING TASK FORCE (IETF) Open international community of network designers, operators, vendors,
and researchers concerned with the internet architecture and smooth operation of the internet
Develops and promotes standards for the TCP/IP and Internet protocol suites
Work closely with W3C and other standards organizations like ISO and IEC (International Electrotechnical Commission)
VIDEO: https://www.youtube.com/watch?v=Fpuzl9lvOSM
REQUESTS FOR COMMENTS (RFC) Documents published by the IETF
Describe methods, behaviors, research or innovations for the Internet
They include detailed information about standardized Internet protocols (TCP/IP)
And they also include informational documents regarding protocol standards assigned numbers, host requirements, and router requirements
INSTITUTE FOR ELECTRICAL AND ELECTRONIC ENGINEERS (IEE) Creates standards relating to various technologies, including those used on
the Internet Ethernet Wireless Ethernet
They also publish industry journals Communications Magazine Information Theory Computer Graphics and Applications Power and Energy Magazine Wireless Communication
TELECOMMUNICATIONS INDUSTRY ASSOCIATION (TIA) Responsible for creating various standards including:
TIA/EIA 568-B: cabling standards that include the RJ-45 jacks and plugs used throughout the world to connect computers. This standard also includes the RJ-11 plugs and jacks used in many countries for regular telephone use
TIA/EIS-598: fiber-optic standards that ensure quality high-speed networks across the world
