Maintain Computer Equipment and System I Lesson Computer maintenance is very important for keeping your computer running smoothly. A computer which is left untreated, can accu- mulate dust and debris, which may result on slow performance. Additionally, your computer may get infected with virus or malware if your antivirus is not up- dated. After going through this lesson, you are expected to : undergo systems cleaning minor maintenance, replacement of consumables, implement proce- dures for ensuring security of data, including regular backups and virus checks and perform basic file maintenance procedures. Learning Task 1 : Answer the activity below. Write your answer on a separate sheet of paper. Maintenance is an important factor in quality assurance and in some cases determines the long-term success of a company. Poorly main- tained resources can cause instability and partially or completely pause the production. Malfunctioning machines or complete breakdowns can become a costly process for most companies. a set of number cell. Lifespan of technology (usability before requiring equipment replace- ment) is increasing, while the cost of computing technology is dramatically low- ering. Hardware and software is still usable years after purchase, however computers do require maintenance to work properly. When people notice their computer’s performance slowing, the most common reason is the hard disk. Your computer’s hard disk is a non- removable area that holds all the information available from your computer. Over time, hard disks begin to lose their ability to store data efficient- ly.” (Speed up you PC: Automate your computer maintenance schedule – Mi- crosoft 2012) 8
