Upon completion of this course, a student should be able to correctly identify all parts and names of computer systems, understand how they fit together, be able to change parts, and carry on a technical conversation about a computer system over the telephone.
This course will also prepare the student's mind in upcoming classes, in that they will have seen what is `inside the box' and can have a better understanding about what is taking place.
The first segment is about safety first. It is a lecture that last about 3 minutes.
The segment(s) about memory, the different kinds of memory, and what the micro-p does with memory is also a lecture. This is where some math is applied so that students can have some understanding how processors handle information.
This should be taught with an overhead and visual tools to support base numbering systems such as hexadecimal. (I have a number of software tools for such educational purposes, which could be embedded in a PowerPoint presentation).
As the discussion of memory moves into virtual memory as stored on a fixed disk, the instructor can make samples available for students to handle (safely).
The following segments of the bullet point list can be easily covered between hands-on instruction and visual aides.
While there are certain network and modem interfaces that must be discussed for the student to learn about Internet connectivity, other interface topics may be left as an option for the instructor.
The student must be able to handle all (or most) of the components brought up in instruction and discussion. While there are times at which the instructor will lead a lecture, or instruct in an unseen topic, such as the internal workings of a microprocessor, the majority of the instruction is intended to be hands-on. Manipulating the objects themselves is an excellent experience for the students.
Throughout the course work were hardware interfaces are concerned, the student should be taught some basic trouble shooting skills. It need not be specific with each item, only to instill an understanding of how to recognize improper operation.
A written quiz, covering topics of terminology and application testing to determine what component has failed. No knowledge of testing tools is required. The student should merely know that a particular component should be tested or replaced as part of a test. To be sure that the student has a full understanding of the concepts, a written answer of a few words would be preferable to giving away answers with multiple-choice formats.
Each student should be able to mount and dismount components from inside a computer system cabinet. To include cards and drives.

Throughout the course the students will have an opportunity to look at a historical sampling of the same types of hardware that they are learning about now. This will display the advents of engineering to improve and miniaturize component elements.
CPU history and explanations of current technologies as it relates to hardware interfaces.
