Chapter 1 PROBLEM AND ITS SCOPE Introduction Nowadays computer has become part of our daily lines. Coming from technology where it is faster, better and more instigated into our daily lives every day. Researchers can’t resist how valuable it is for everything researchers do. Basically computers are made to make our work become easy and fast. Most of the people see our future being based on technology and it is even influential in today’s life. A computer consists of parts, first is the housing or the box that we commonly called the CPU, the motherboard, is a printed circuit board in a computer. Motherboard is the computer’s central communication or the backbone connectivity of a computer that connects all the devices that to be in-touched with the motherboard. The PSU or the power supply unit, is where the main source of power of the computer, this will convert the 220 volts of electricity to the precise voltage to be needed by other components inside the computer. The CPU or the central processing unit also called the brain of the computer, a computer component that is responsible for interpreting and executing most of the commands from the computer’s other hardware and software. The CPU fan or the heat-sink, is critically necessary to ventilate the heat generated from the components and actively cools the processor. The RAM or the random access memory, is a physical hardware inside a computer that temporarily stores data, serving as the computer’s working memory. There are more components of the computer that are not necessarily to be discussed.

2 Computers are machines and machines will soon to come up with malfunctions, such as hardware interruptions. These are the common problems for those owners who don’t have any knowledge of computer troubleshooting. Some of them gets irritated when something happens on their computers, commonly are those program crashes and end up with a hang-up computer. There are also problems from starting up the computer; it will come up with a blue screen, no display and other varieties of system failure. When having all these problems it will require experience and knowledge about what’s inside that box, or the CPU case. Opening that case without any familiarity will just lead the user to congestion of wires and misplacement of desired object that to be placed on those specific slots, and if that happens that will damage some parts of the motherboard or system unit. To have understanding on computer troubleshooting it requires the familiarity and the training from professionals or own experience or self-taught but may take some time and dealt a higher risk of damage. There are organized trainings for those who wanted to have expertise on even some knowledge and skills in computer configuration. A simulator is a system that do simulation, it is the imitation of the operation in actual and to the real-world process. The act of simulating something will require a developed model of the precise field. The model represents the key characteristics, behaviour and functions of the selected physical or abstract. This study aimed to produce a comprehensible computer configuration simulator that simulates the features of NCII Computer System Services test package. This study aided the user to understand the concept of computer configuration.

3 This will give convenience to the users in configuring the computer. So the researchers have undergone research in order to have the right solution and to make this study possible. Conceptual Framework This study is based on the concept of “The Conduct of an effective Simulation” conducted by (Conway et.al, 2003) that provides warnings and a suggestion to improve simulation. Although the software tools to develop simulation models have improved intensely, relatively little has been written about how to make effective exercise those models. This study delivered warnings and suggestions to improve simulation studies. Although based primarily on the author’s experience with discrete-event models in conducting simulations. It simulated different components of a computer system. It describes the procedures of PC building in a quick, simple and compact fashion using a simulator. It also understands how to take a problem and develop a simulation based model for it, analyzed the result and presented the results convincingly. This allowed user to have a complete graphical components of a computer and will be able to drag and drop those components into the workspace. Computer components and its connecting wires can be configured using context-sensitive menus. The environment of the project will open a window sized application. The application have has buttons where the user can choose what to launch but first it needs to register user account so the user can log in with the application. After the user log in an account it’s either the user will choose a complete process from the beginning up to the end or choose a specific course of the simulation.

4 If the user is going to select menus the user will go to a window that will simulate the process from the beginning such as PC building up to the end of the installation of the operating system. It will let the user to choose a selection of stages; user can select what part of the simulation process will be launched.

Figure 1.Computer Aided Application for Computer System Servicing The figure above depicts the diagram of the study. It is a representation that describes a pattern of thought that organizes categories of information. The start of the process shows that the user must sign up first the account in completing account details, after completed in creating new account the user can now log in the account. When the user can log in the account the user can select what part of the course to be launched. Once the user chooses an option or menu this will redirect to a new environment which

5 the simulation is to be done. After the simulation is being processed it will conduct an output which will give the user the result of the simulation. The diagram on the page 7 shows the flow of the system, Computer Aided Application for Computer System Servicing. It is represented by the three procedures which are the Input, Process and Output. The First box contains the input of the system. These are the core competencies of Computer System Servicing which are the Install and Configure Computer Systems, Set-up Computer Networks, Set-up Computer Servers, Maintain and Repair Computer Systems and Networks. Install and Configure Computer Systems is a unit, that covers the outcomes required in installing and configuring desktop and workstation computer systems. It consists of competencies to assemble computer hardware, install operating system and devices for peripherals/devices and install application software as well as to conduct testing and documentation. Set-Up Computer Networks is another unit, that covers the outcomes required in setting-up computers networks for LANs and small office home office (SOHO) systems. It consists of competencies to install network cables, set network configuration, set router/Wi-Fi/ wireless access point as well as to inspect and test the configured computer networks. Set-Up Computer Servers is a unit, that covers the knowledge, skills and attitudes needed to set-up computer servers for LANs and SOHO systems. It consists of competencies to set-up user access and configures network services as well as to perform testing, documentation and pre-deployment procedures. Maintain and Repair Computer Systems and Networks covers the knowledge, skills and attitudes needed to maintain and service computer systems and networks.

6 The Second box is the solution of the relevant problems the researchers encountered. It represents the process of the system development cycle containing the following process: Data Gathering, Requirement Analysis, Designing, Coding, Testing & Evaluation, Implementation, and Documentation. Data Gathering is the first phase which processes the gathering and measuring information on variables of interest that enables one to answer stated research questions, an established systematic fashion, test hypotheses, and evaluate outcomes. Requirement Analysis where it is critical to the success or failure of a system or software project, also called requirements engineering, is the process of determining user expectations for a new or modified product. These features, called requirements, must be quantifiable, relevant and detailed. The requirements should be documented, actionable, measurable, testable, traceable, and defined to a level of detail sufficient for system design. Designing is a plan specifying how the researcher intends to fulfill the goals of the study. Its complete design tends to produce significant and correct conclusions, the process of creating a design can be brief (a quick sketch) or lengthy and complicated, involving considerable research, negotiation, reflection, modelling, interactive adjustment and re-design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork and some engineering, coding, and graphic design) is also considered to be a design activity. Coding is the transformation of the data into a form suitable for computer-aided analysis. It is the process of assigning a code to something for the purposes of classification or identification, while language is a set of syntax rules that define how a code should be written and formatted. Testing and Evaluation involve collecting and

7 analyzing information about the outcomes. Its purpose is to make judgements about a program, to improve its effectiveness, and/or to inform programming decisions, the process by which a system or components are compared against requirements and specifications through testing. The results are evaluated to assess progress of design, performance, supportability, etc. Implementation which is the final stage in which the software is run on various systems by users. If it runs smoothly on this system without any flaw, then it is considered ready to be launched. Documentation describes the use, operation, maintenance, or design of software or hardware through the use of manuals, listings, diagrams, and other hard- or soft-copy written and graphic materials. Provides official information or evidence or that serves as a record. The Third Box shows the output of the Computer Aided Application for Computer System Servicing. Through this application system the trainees can directly be able to interact on the core competencies in an animated way like on the actual process, components will be animated and associates with other animated components like the actual computer configuration without any error or damage and it will give convenience to them. It will also help the trainers reduced their time spent in conducting training with the trainees. The admin can view all the details of the students from the database with which the students registered their account. This will also help the trainers for an easiest and fastest way in taking the training and exam. Lastly, the system will generate training report or the outcome of the simulation.

10 NC II Assessor. This system helped the assessor to reduce effort in observing and conducting the competency assessment. IT Education Faculty. By approaching a system at a higher level of abstraction, the designer is better able to understand the behaviours and interactions of all the high level components within the system and is therefore better equipped to counteract the complexity of the overall system. This complexity may simply overwhelm the designer if the problem had been approached from a lower level. As the designer better understands the operation of the higher level components through the use of the simulator, the lower level components may then be designed and subsequently simulated for verification and performance evaluation.
