We examine storage devices in computers. This storage lecture has been broken up into to two section, this one focuses on hard drives and RAM, the next video covered removable storage devices.
The second part of our storage videos. This video looks at some of the removable storage media you can use. We look at floppy drives, CDs, DVDs, Blu-ray and ROM (flash memory).
Video 5 in our introduction to computers series looks at computer input devices. We examine some common input devices and look at how to clean your keyboard and mouse.
Our last video in our Computer Hardware lesson, part of the Introduction to Computers course.
This video looks at the most common output devices found on a computer we also list out top 5 resources, be sure to check them out.

For all intents and purposes, this show is the fourth edition of the textbook Computer Organization and Design Fundamentals by David Tarnoff. Since the first edition came out in 2005, the PDFs have been made free for download to anyone interested in computer organization. With the trend toward audio and video instructional material, it was time for an update.
The presentation of the material in this series will be similar to that of the original textbook. In the first third, we will discuss the mathematical foundation and design tools that address the digital nature of computers. This will include an introduction to the differences between the physical world and the digital world, how those differences affect the way the computer represents and manipulates data, and the use and design of digital logic and logic gates. In the second third, the fundamentals of the digital logic and design will be used to design common circuits such as binary adders, describe checksums and cyclic redundancy checks, network addressing, storage devices, and state machines. The final third will examine the top-level view of the computer. This will include a discussion of the memory hierarchy and its components, the components of a CPU, and maybe even a discussion of assembly language along with some examples.
This unit discusses the purpose and types of programming languages from simple machine code to high level programming languages, including the process of compiling and interpreting. Students will use variables, loops and conditional statements to build a simple program. Finally, this unit presents some advanced programming concepts such as Object Oriented Programming.
This unit covers application and system software, with a focus on healthcare systems. It also describes the functions of operating systems, presents different operating systems, and defines the purpose and usage of file systems.
The first video in the Computer Software series, part of our Introduction to Computers course. This video looks at the general types of software, software development, the software development life cycle, as well as explains what computer programers do.
Welcome to one of the most geeky videos in the entire series. This video will introduce you to the computer boot process, the way a computer starts from the moment you turn the computer on, till the operating system kicks in.
Video 3 of our Introduction to Computer course. This course looks at the basics of operating systems. We take a look at what an operating system is, file systems, user interfaces and command line.
In the previous video we looked at the basics of operating systems. In this video we take a look at the current operating systems available to consumer. In addition to looking at Windows, we also cover the current Mac OS X, Linux and Mobile Operating systems.

Our last video in the Computer Software lesson, part of our Introduction to Computers curriculum.
In this video we look at the types of application users can find. We talk about business software and personal software. We also give our 3-5 to picks for viewers to check out.

Video 4 in our Introduction to the CompTIA A+ Certification Exam looks at the tools the computer technician should have in their bag in order to get the job done. We look at hardware tools for computer repair and software tools for computer repair.
This webinar (recorded Sept. 27, 2017) introduces how to connect other services as add-ons to projects on the Open Science Framework (OSF; https://osf.io). Connecting services to your OSF projects via add-ons enables you to pull together the different parts of your research efforts without having to switch away from tools and workflows you wish to continue using. The OSF is a free, open source web application built to help researchers manage their workflows. The OSF is part collaboration tool, part version control software, and part data archive. The OSF connects to popular tools researchers already use, like Dropbox, Box, Github and Mendeley, to streamline workflows and increase efficiency.
This video will go over three issues that can arise when scientific studies have low statistical power. All materials shown in the video, as well as the content from our other videos, can be found here: https://osf.io/7gqsi/
Students analyze video clips of kids rolling down a hill on skates, scooters, and bikes to determine whether mechanical energy is conserved.
A high speed video clip of a roller coaster is used as an example of conservation of mechanical energy. Students use the video to determine whether mechanical energy is conserved while the roller coaster rolls up, and then back down a hil.
This video from the Explore Economics series helps kids understand that people are both consumers and producers. Kids learn that consumers buy goods and services to satisfy their wants and that producers make goods and services. Kids are encouraged to be producers by making a bookmark, and then to be consumers by using a bookmark to hold their place in a book. Students learn a song about goods and services.
In this video segment adapted from LOKE Films and the Arctic Monitoring and Assessment Programme, learn how human populations in the Arctic are affected by industrial contaminants in the food chain.
This example explains how contour mapping teaches both estimation and spatial visualization skills. To have experience visualizing 3-dimensional fields from a 2-dimensional map helps students throughout their mathematical career. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.
