IT SKILLS WORKSHOP

The IT Skills Workshop (ITSW) is a mandatory part of your education at UOIT

Each course you take this semester is integrated within the ITSW project with its own requirements for each course.

There are 1.5 workshop hours per week for your cohort (student year), of which you must attend.

ITSW workshop hours September 17th December 3rd (inclusive) on Thursdays from 2:10pm 3:30pm in UA3220.

The workshop coordinator for this year is Garrett Hayes ([email protected]).

In this workshop you will apply your knowledge learned in each course to analyze and/or implement pieces of a semester long project, depending

on the context.

Workshop timeslots will be distributed to you via Blackboard at the beginning of the semester.

IT SKILLS WORKSHOP (Project Scenario)

The International Travel Agency (ITA) is a multinational corporation that provides packaged travel services for small to medium enterprises

(SMEs) around the world.

Thousands of customers and hundreds of employees

Currently their centralized data center is connected to multiple regional offices in order to centralize their IT resources.

The ITA has contracted your team to monitor and troubleshoot any network-related issues occurring between their core network and Travel

Data Provider (TDP) endpoints.

Working together as a team, you are responsible for implementing a web-based product that can be used to ease the difficulties of

troubleshooting their complex network topology.

Valid software solutions could streamline a variety of issues, including (but not limited to): remote device monitoring, ticket management,

automating known troubleshooting methodologies, collecting real time

routing information, automated log parsing and classification, etc.

7



Each included courses assignment or final project will be implementing some aspect of this project scenario.

Each instructor will define a deliverable that relates to the scenario above while meeting the evaluation and metric requirements for the

completion of their course. For example, in your Advanced Networking III

course, you will be responsible for identifying ways software automation

can be used to automate or facilitate network troubleshooting

In your Web Programming course you will be developing a web interface (and underlying software) that can be used to help automate

the troubleshooting process.

Each course instructor will be providing you with specific details regarding the portion of the project included in their course (deliverables,

completion requirements, metrics, etc.). Instructors will set their own

deadlines for their portion of the IT Skills Workshop. You will be

responsible for meeting their requirements in each course.

8



Students identify interesting projects (groups of 4)

Requirements:

- Make use of HTML, CSS, Javascript. PHP, mySQL (all topics covered in class)

- Should access a DB (mySQL + PHP)

- Should use at least one API not covered in class (examples, no limited to:)

- https://developers.google.com/maps/web/?hl=en (google maps)

- https://developers.google.com/youtube/ (youtube)

- Integration to social networks (facebook, twitter, pinterest, etc..)

- http://www.programmableweb.com/api/accuweather (AccuWeather)

Please submit your project proposal (blackboard) by Friday Sep 17, 2015.

Resources

High-quality online resources are freely available for much of the content covered in this course. For each class, online references will be given

that students can refer to. Links to online resources will be posted in

Blackboard for each class as required. Any sample code or presentation

materials used during class will also be made available for students to

keep as a reference.

Online Resources

- www.CodeCademy.com - Each student will need to sign-up for a free

account on this site.

unless proper documentation is provided.

The purpose of the quizzes/inclass assignments is to promote attendance and typically they will be easy enough to complete and

obtain a good mark provided you attend the lecture.

Depending on the number of these activities, one or two lowest mark(s) will be dropped.

Future Research Directions (1/3) For the long term...

1) Opportunistic ad hoc communication

mechanisms

- take into consideration high mobility and QoS

- speed, type of message, quality of communication

- To allocate channel times more efficiently

2) Cluster-based mobility management

- Objective: reduce network overhead, handoff

latency (in platoons)

The World Wide Web

Affectionately called The Web

It is a collection of information stored on the networked computers over the world.

The WWW was proposed in 1991 by

Tim Berners-Lee at CERN.


Web or Internet?

They are not the same thing!

The Internet is a collection of computers or networking devices connected together. - They have communication between each other.

- Decentralized design that there is no centralized body controls how the Internet functions.

The Web is a collection of documents that are interconnected by hyper-links. - These documents are accessed by web browsers and

provided by web servers.


Internet Terminology

Client - Any computer on the network that requests services from

another computer on the network.

Server - Any computer that receives requests from client

computers, processes and sends the output.

Web Page - Any page that is hosted on the Internet.

Web Development - The process of creating, modifying web pages.


Web Browser (Web Client)

It is a program that retrieves information from the Web.

Web-servers

A web browser is a software application for retrieving, presenting and traversing information resources on the World Wide Web.

An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of

content.

Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

HTML

Introduction

HTML Example

My First Heading

My first paragraph.

The DOCTYPE declaration defines the document type

The text between and describes the web page

The text between and is the visible page

content

The text between and is displayed as a heading

The text between and is displayed as a paragraph


What is HTML?

HTML is a standard language for describing web pages.

HTML stands for Hyper Text Markup Language

A markup language is a set of markup tags

The tags describe document content

HTML documents contain HTML tags and plain text

HTML documents are also called web pages

TAGS content

HTML tags are keywords surrounded by angle brackets

HTML tags normally come in pairs like and

The end tag is written like the start tag, with a slash before the tag name

Start and end tags are also called opening tags and closing tags

55


HTML Page Structure

My First Heading

My first paragraph.

56


The Declaration

A browser can only display an HTML page 100% correctly if it knows the HTML version and type used. (there are many different documents on

the web)

HTML5

HTML 4.01

XHTML 1.0

57


Writing HTML code

Use Notepad (or any simple text editor)

AVOID:

- Adobe Dreamweaver,

- Microsoft Expression Web

- CoffeeCup HTML Editor

WHY?? For learning purposes

58


Your first HTML page

Write or copy the following code into Notepad

My First Heading

My first paragraph.

Save as .htm (or .html)

Double click your HTML file to see the results

59


HTML Elements

Start tag * Element content End tag *

This is a paragraph

This is a link

An HTML element is everything from the start tag to the end tag:

Some HTML elements have empty content

Empty elements are closed in the start tag

Most HTML elements can have attributes

60


Nested HTML Elements

HTML documents consist of nested HTML elements.

My First Heading

My first paragraph.

The element defines the whole HTML document.

The element has a start tag and an end tag .

The element content is another HTML element (the body element).


HTML Attributes

HTML elements can have attributes

Attributes provide additional information about an element

Attributes are always specified in the start tag

Attributes come in name/value pairs like: name="value"

This is a link

Links are defined with

The link address is specified in the href attribute *Attribute values should always be enclosed in quotes
