DF099 How Computers Work and Store Data

This course was funded by the Bureau of Justice Assistance.

The first module of this course covers fundamentals such as recognizing computer components and their functions, accessing computer firmware, and the startup and shutdown processes. The second module covers how a hard disk drive works, how data is converted into digital information, how to calculate the storage capacity of a device, partitioning and how that is used for storage, and how a solid state hard drive functions.

This course serves as a prerequisite for BDFA-Acquisition but can also be completed as a stand-alone course.
