However, most of a computer's hardware cannot be seen; in other words, it is not an external element of the computer, but rather an internal one, surrounded by the computer's casing tower. A computer's hardware is comprised of many different parts, but perhaps the most important of these is the motherboard.
The motherboard is made up of even more parts that power and control the computer.
In contrast to software, hardware is a physical entity. Hardware and software are interconnected, without software, the hardware of a computer would have no function. However, without the creation of hardware to perform tasks directed by software via the central processing unit, software would be useless.
Hardware is limited to specifically designed tasks that are, taken independently, very simple. Software implements algorithms problem solutions that allow the computer to complete much more complex tasks.
For example, a program that is designed for the Windows operating system will only work for that specific operating system. Compatibility of software will vary as the design of the software and the operating system differ. Software is capable of performing many tasks, as opposed to hardware which can only perform mechanical tasks that they are designed for.
Software provides the means for accomplishing many different tasks with the same basic hardware. Practical computer systems divide software systems into two major classes:.
Unit 6 must be preserved if at all possible. The capstone experience for the course, Unit 6 enables students to apply the skills they have learned in a large-scale, individualized project setting. Cutting this unit would deprive students of the opportunity to experience a close approximation of a real-world development setting. Earlier units should be condensed or cut as necessary to ensure that Unit 6 is still included in the curriculum.
Daily lesson plans Most lesson plans in this curriculum are designed to represent a single minute class period with average pacing. Each class will have slightly different needs, possibly including different period length, student capabilities, classroom interruptions, and more. Teachers and volunteers are encouraged to consider the lesson plans as guidance for one possible use of time to present the material, and to feel free to adapt the lesson plans as necessary to fit the needs of the particular class in which the plans are being applied.
During this time, teachers are encouraged to assign "bell work" sometimes called "do now" activities for students to work on. These activities aim to engage students with the subject immediately upon entering the room, and should be short, clear, and able to be completed by all students. Specific "do now" activities are not given in the lesson plans, as they should be chosen by the teacher to reinforce or preview the specific topics with which students have or are expected to struggle most.
These sections should be kept as brief as possible—the primary means of student learning in most lessons will be the lab activities. The goals of the instruction section of the lesson should be to motivate the concepts being exercised in the lab and to provide a short demonstration to help students find the necessary parts of SNAP the first time.
Teaching teams should vary the ways in which the instruction is presented throughout the course, including class discussions, kinesthetic activities, demonstrations, Socratic seminars, occasional lectures, and other approaches. Each activity is broken down into several parts, each of which consists of several steps.
In general, the steps in a single section build on each other, and each section covers a new topic or new application. It is intended that the labs be well enough structured for students to work through on their own, but teachers should feel free to interject at appropriate points to assess student progress and provide additional guidance as necessary. On occasion, steps 3 and 4 are repeated for multi-part activities. In general, there is not enough time, nor is there necessarily the need, to go through the lab step-by-step.
Students should be able to at least partially assess their own progress by verifying that their programs function as specified in the lab. Rather than presenting solutions to each step of the lab, teachers are encouraged to use the debrief time to focus on particularly tricky or noteworthy parts of the lab or to discuss areas in which students struggled.
Debrief time can also be used to compare and contrast different possible approaches to some of the problems, emphasizing that, in most cases, there is more than one valid solution. Slides for Lecture 6 PDF - 1.
