Beginner's Guide to Information Technology

This lecture introduces Section 2 of the course, Computer Architecture, and gives an overview of what students will learn in this section.

This lecture covers the basic parts of a computer. By the end of this lecture students will have a better understanding of the inner workings of a computer. 

This lecture covers two important concepts in IT, hardware and software. By the end of this lecture, students will know the difference between hardware and software and the role that these two concepts play in computer architecture. 

This lecture covers the topic of bits and bytes, aka binary code. By the end of this lecture students will understand what these terms mean and why they are important in computing. 

This lecture covers the two most important chips in any computer, the CPU and GPU. By the end of this lecture students will know what these are and why they are important. 

This lecture covers the different types of computer memory that exist. By the end of this lecture, students will understand the differences between these types of memory. 

This lecture covers what peripheral devices are and why they are important to computing. 

This lecture summarizes Section 2 of the course, Computer Architecture. By the end of this lecture you will be ready to take the section quiz and then move on to Section 3 of this course. 

This lecture introduces Section 3 of the course and provides a brief overview of what will be taught in this section. 

This lecture covers the OSI 7 Layer Model. By the end of this lecture, students will understand the role that each of the different layers plays in Computer Networking. 

This lecture covers Network Topology. By the end of this lecture students will understand what network topology is and why it is important in computer networking. 

This lecture covers the different types of cables used in computer networking: coaxial, twisted pair, and fiber optic. By the end of this lecture, students will understand the strengths, weaknesses, and differences in all of these types of cables. 

This lecture covers the concept of packets and their role in networking. By the end of this lecture you will understand the concept of packets and why they are important in passing data from computer to computer. 

This lecture discusses what hubs and switches are and why they are important in computer networking. 

What exactly is an IP address? This lecture will answer this question in detail and help students to understand how computers are identified and communicate within a network. 

This lecture explains what clients and servers are and their role in networking. 

This lecture explains what requests and responses are and why they are important in computer networking. 

In this lecture, we will use Charles Proxy to intercept web requests hands-on in order to better understand requests and responses. 

This lecture will teach students what happens when you type in a URL. I bet you will be surprised about how many things happen behind the scenes just for something as simple as navigating to a webpage by typing in a URL. 

This lecture will summarize what was taught in this section. 

This lecture introduces Section 4 of the course to students. 

This lecture covers what a terminal or command line is and its role in computing. By the end of this lecture students will understand what a command line is. 

This lecture covers file directories. This concept is an important building block for us using the command line in our hands-on segment in this lecture, as the command line uses file paths for navigation. 

This lecture introduces some of the basic commands that students can use to interact with the terminal. 

In this lecture we will use the basic commands we learned in the last lecture and apply them hands-on using the command line terminal. 

This lecture summarizes what was taught in Section 4 of this course. 

This lecture reviews all of the tech jargon and key terms taught in the course and is meant to summarize and reinforce all of that knowledge. 

This lecture serves as the summary and course wrap-up recapping what was taught in this course.
