TECHNICAL CONCEPTS

Now we will analyse the analog and digital data. We will discover the difference between data and information. And the functions of Operating Systems.



Analog and digital data:
How Analog and Digital Recording Works, is a interesting tutorial that differences well the analog and digital data.

Difference between data and information:
This web page summarizes and makes concise reference to the differences between analog and digital data. Understanding the Difference Between Data and Information.

Operating Systems:
How Operating Systems Work this webpage provides a good and thorough introduction to this very important concept.

SEARCH ENGINES

Today we will talk about Search Engines, how they work, rank and how to create them. Their underlying mechanism, characteristics and some of the potential implications on individuals and society of their manipulation.

Here there is a picture of a search engine web :

In the following website there is a large amount of information to find out about search engines:

The following video talks about the creators of Google and search engine optimization.

Finally here there is a article about this topic, even though it is in spanish it is still very interesting.

This article talks about Google being the largest search engine and some negative points about searching over the internet.

OUR MAIN FOCUS

The main objective of this blogspot is to portray the impacts that technology has on individuals and society.

As humanity knows, the 20th century has seen extraordinary advancements in the world of technology. Modern society has seen discoveries/inventions in medicine, science, transportation, engineering, and communication of unparalleled magnitude and proportions.

The impact of these technologies on modern society has been undoubtedly beneficial but some might argue the contrary.

We will analyse:

• SEARCH ENGINES: how they work, rank and how to create them. Their underlying mechanism, characteristics and some of the potential implications on individuals and society of their manipulation.
• TECHNICAL CONCEPTS: such as: Analog and digital data, Difference between data and information, Operating Systems.
• Ergonomics, Teleworking, Password Protection and Biometrics.
• NETWORKING: we will analyse the fundamentals of networks, different topologies and other technical concepts as a first step towards discussing the implications of networks on society and individuals. We will also show how to design networks.
• E-COMMERCE: we need to analyze some of the technical and theoretical background related to its development and evolution.
• HACKING: subculture of hacking, its potential threats and implications for individuals and societies.
• DATA SECURITY AND ENCRYPTION: after learning about hacking and how it compromises data security, we will learn about the next step in protecting data, by means of encryption.
• ROBOTICS: analyze the various applications on robotics in modern society as well as the ethical and social implications of a more widespread use of robotic technology.
• ARTIFICIAL INTELIGENCE AND EXPERT SYSTEMS: a logical next step in the study of Robotics and its ethical and social implications is to focus on the software that makes robots acquire quasi human capabilities. The software that runs robots, as well as other modern technology applications, is based on Artificial Intelligence.
• SIMULATIONS AND MODELING: unit will focus on the effectiveness, usefulness, limitations, and the social and ethical impact of the increased use of simulations.
• TUTORIALS AND WIZARDS: how the apply to training. The objective is to try to understand how the use of technology affects the way people learn, both in the academic environment as well as in job training.
• HOW TECHONOLY IMPACTS ON EDUCATION.
• THE 21st CENTURY BUSINESS: technology has impacted businesses very significantly, and resulted in increased productivity. However, there are issues associated with the generalized use of technology in the workplace that have affected both positively and negatively individuals and society.
