Introduction to Information Technology

Welcome to Information Technology Essentials!

Information Technology Essentials is designed to be an introduction to Information Systems. The material is similar to many of the topics that first-year information technology students study. The book is broken down into sections that cover a variety of areas of information systems.

These topics include:
- Why you would want to study information technology
- A basic introduction to computer hardware
- The software development lifecycle
- Database Management Systems
- Computer networking
- An introduction to cloud computing
- How to sign up for a free account with Amazon AWS
- Computer security
- and The future of computing

This class is for anyone who wants to learn about the Information Technology field, but is ideal for people who are just getting started. The material will provide you with a solid understanding of many of the concepts that drive one of the most critical industries in today's world.

Key Concepts Included in This Course

To get started in information technology you need a baseline understating of some of the key concepts that drive this industry.  In this course we cover many of the topics that Freshmen students learn in college IT courses.

Database Management Systems

In this module, I will start with a discussion of relational databases, which make up the majority of products on the market today. Next, I will then briefly describe the basics of the Structured Query Language, or SQL. If you work for a large company, or a government agency, you will probably work with an extensive database that your organization runs and maintains. The necessary information in this chapter will give you the basics of how these systems work

Cloud Computing

Cloud computing is one of the fastest growing areas of information technology today. Many companies and government organizations are moving large-scale systems from their own data centers, and into the cloud. What is the motivation behind this? Why would companies want to give up control of some of their vital systems, and move to the cloud? I will discuss this and many other issues related to cloud computing in this chapter.

Computer Networking

Computer networks allow systems to extend their reach and interact with other computers and users, on their local area network. If their network is connected to the Internet, then users will have access to software and services worldwide. Computer networking is a very important part of information technology. The demand for network hardware and services has exploded since the introduction of the Internet. In recent years, we have not only seen a huge growth in wired networks, but, with the worldwide adoption of cell phones, we have also seen an explosion in the growth of wireless networks.
