Computer appreciation is the technology impart of understanding computer through learning and practicing the first-step of its composition, scope, and operations in ICT World. This is for basic, but for advanced, it is to support the computer application knowledge of the intermediate and advance computer users, who perform their daily activities with computer. By comparison, appreciation is different from application, which is the technical impart of understanding how to use application programs of computer through practices. Meaning that their key different is the ability to perform effectively in application via the knowledge gained from the appreciation. Following this point, the package of CAplus is to help users gain and improve in both appreciation and application. To achieve this point, the package is organized into CAplus-1, 2, 3, and 4 books. The CAplus-1 consists of section-one and two. The Section-One contains chapter one to five with topics on history of computer, the meaning, attributes and uses of computers, including the classifications of computer, common components basic operations of computer relatively. The Section-Two is titled "building computer career," which comprises six examples of computer career topics, with cases of teaching students on how to build and enhance computer careers through educational system, participatory in application program training, and relative software to each specialized area of the career. The CAplus-2 was written for advanced-level in order to help students in studying of computer's components. To support its central teaching, the book explained the hardware and software components of computer, and how they function systematically in the work process of computation. In this form, the knowledge-gained about these components will help students in learning computer maintenance and repair, troubleshooting identification, and how to manage computer threats as all of them are the central teachings in CAplus-4, which also taught about the basic maintenance and repair of Windows Computers. For the CAplus-3, the general study of computer appreciation is not complete without the introduction of computer application, and since Windows Operating System (OS) is the main OS in the work of CAplus, therefore "windows appreciation" was written as a prepared take-off ground for computer application training. To widen the book (i.e. the CAplus-3), the concept of file, and folder were treated, including other Chapter topics on "internet appreciation," "computer threats appreciation," and "evaluating of PC quality." So the studying objectives are as follows: know how to setup a desktop computer; know the basic integral parts of Desktop; know the basic integral parts of Windows; know the basic, necessary, uses and functions of the control panel of Windows OS; gain the preparation ground for Windows and other software maintenance; know how to access the Windows tools of a computer; know the components of Windows Operating System; understand the scope of Internet and its application; understand what is virus and malware; understand how to remove and prevent computer threat; and how to evaluate the quality of a personal computer. Generally, it is advisable to use both CAplus-1, 2, 3, and 4 in order to achieve the complete benefit-effectiveness of the package.
