Establishes and maintains the smooth operation of computer systems (including operating systems, software, and hardware) in networked or standalone configurations, maintains system integrity, and upgrades systems and/or servers as required. Computer maintenance is a periodic or preventive process aimed at ensuring that computer hardware and software continue to operate efficiently. It includes early detection of malfunctions, cleaning from dust, virus removal, and software updates. These processes aim to protect the device from damage, increase its speed, and avoid future technical problems. Types of Computer Maintenance: Preventive Maintenance: Proactive measures to protect the device (such as cleaning fans, removing temporary files) to prevent malfunctions before they occur. Periodic Maintenance: Scheduled inspections (daily/monthly) to ensure performance efficiency. Corrective Maintenance: Repairing or replacing hardware or software components after a malfunction has actually occurred. Examples of Computer Maintenance Uses: Cleaning Hardware Components: Removing dust from the motherboard and fans to avoid overheating. Software Check: Removing viruses and updating the operating system (Windows/Linux) and software. Component Maintenance: Replacing the hard disk (HDD/SSD), increasing RAM, or disassembling and reassembling the computer. Network Management: Setting up home networks and solving internet connection problems.
