After studying networks and the various ways in which businesses and organizations share valuable information, we will analyze the subculture of hacking, its potential threats and implications for individuals and societies.

We will start by watching the following video on the History of Hacking, produced by Discovery Channel:

1- Why is ergonomic design considered to be important in today’s workplace? (10 points)
2- For what applications would you use biometrics over passwords? (10 points)
3- How does a non-multitasking operating system simulate multitasking? (10 points)
4- Explain what criteria you would use to select whether to use hubs, switches or routers in a network. (10 points)

6- A shoe store wants to setup its IT operation. They own a shop where they sell shoes to the public, and at the shop they have 5 point of sale (POS) computers that use a common printer for the printing of invoices. The manager of the store has his own computer and printer that needs to be networked to all the others. All computers in the store access the Internet though a cablemodem. The store needs to be connected to the firm’s central office and warehouse. At the central office, the administration has 4 computers with their own file server and printer, and they are also connected to 3 computers in the warehouse that are used for stock control and that have their own printer. All computers at the central office and warehouse are connected to the Internet.Using WebLan Designer, draw up the design of this network and briefly justify the decisions and choices made.

When you finish, please submit your assignment to itgs.sass@gmail.com Make sure that I have received your work before you leave the room.

E-commerce

Our next topic in the sequence is E-Commerce. We are all somewhat familiar and have some first-hand experience on E-Commerce, however, we need to analyze some of the technical and theoretical background related to its development and evolution.

We will start by attending a short lecture on E-Commerce from the online MBA program at Mystamford:



Two web sites that provide general information on e-commerce are:

• Basic Guide to E-Commerce
• Business Link Guide to E-Commerce
  
  Another article from Business Link is interesting to alert users about the Risks of E-Commerce.
  

ASSIGNMENT
Our assignment for the day, to be covered in class, consists in answering the following multiple-choice questionnaire:

• Introduction to E-Commerce Multiple Choice Quiz

In pairs, research the answers to each question until you score all right answers. When you have done so, check your answers with me since I will be asking you a few oral questions on the topic. DO NOT LEAVE THE CLASS WITHOUT ME TICKING YOU OFF THE LIST FOR HAVING COMPLETED THE ASSIGNMENT

Evaluation Topics

This is a very important assignment, which will be done in class.
A fundamental learning outcome of this course, that intends to mirror a real-life scenario, is to help us to develop skills in going through extensive contents and determining what is relevant.
Your task today, to be done in groups of three members, is to come up with the list of relevant topics that we will be evaluating next week, covering Biometrics, Teleworking and Ergonomics, as well as Operating Systems, Data and Information and Analog and Digital Data.
The suggested procedure is:
Divide up the topics amongst the three members of the group, go through the entries in the blog and check the websites that we have seen in class. Skim through the contents in these sites and, referencing the assignments and what was discussed in class, jot down those topics that we made emphasis on.
Also, submit a suggested list of possible ways in which you might be evaluated, taking into account that you will be able to use the Internet, notes and/or any other resources.

The evaluation will take place next Friday, please submit the assignment before the end of teh lesson to itgs.sass@gmail.com, and before Wednesday you will receive my comments on the list, as well as the corrected assignment on network design.
