Computer hardware servicing
IN this article, we will begin to learn about computer hardware servicing which is part of the Information and Communications Technology (ICT) component of Technology and Livelihood Education (TLE) subject in school.
As a short introduction and recall about ICT, UNESCO is positive about learning ICT in school will contribute to universal access to education, equity in education, the delivery of quality learning and teaching, teachers’ professional development and more efficient education management, governance and administration. This is particularly possible through learning computer hardware servicing which is likely beneficial especially for learners from the countryside in the Philippines.
Computer hardware servicing is a blanket term applied to the act of supporting and maintaining computer hardware. This includes diagnosing computer hardware issues, upgrading hardware on a computer and repairing computer hardware. A professional in charge of computer hardware maintenance must be able to perform the following tasks: (1) install personal computer (PC) hardware; and, (2) diagnose computer hardware problems. Installing PC hardware whether desktop or laptop, a student must learn how to install and how to update hardware drivers.
The lesson on computer hardware servicing will provide detailed step by step information about how this can be done but below are the important items that needs to be checked: processor, drive, expansion card, keyboard, motherboard, mouse, power supply, memory, printer and scanner. But the most important thing that we need to note before installing any hardware inside a computer is to open the computer and be aware of Electro Static Discharge (ESD) and its potential dangers.
Many people are faced with everyday computer problems that are easy to fix, but are unable to diagnose the actual problem. While there are many problems a computer will be faced with, this article will tell you where to look for common problems.
The following needs to be checked in order to diagnose a computer hardware problem: (1) Check for Power On Self Test or POST; (2) Notice the load time of the OS (operating system); (3) Notice any graphics problems once the OS has loaded; (4) Perform an auditory test; (5) Check any newly installed hardware; (6) Check any newly installed software; (7) Check RAM and CPU consumption; (8) Listen to the computer, if the hard drive is scratching or making loud noises, shut off the computer and have a professional diagnose the hard drive; (9) Run a virus and malware scan; and, (10) Check for the problem in safe mode.
According to experts, individuals with expertise in computer hardware servicing can expect to see the field increase by 30 percent by 2018. Much of this increase will be seen in the field of network engineering, the field size of which is projected to increase by 50 percent. But even if one has earned computer hardware servicing skills in the countryside, this promises a good source of livelihood already.
A well- taught computer hardware servicing topic in TLE subject in school can inspire students pursue higher studies that will make them become computer technician, IT technical support officer, technical support representative, and computer hardware specialist. ( Paid article)
