Defragmentation is the correct answer because it is a process that reduces the amount of fragmentation on a disk. Fragmentation occurs when files are split into smaller pieces and stored in different locations on a disk, leading to slower performance. Defragmentation rearranges these fragmented files, placing them in contiguous blocks, which improves disk read and write speeds. Therefore, defragmentation helps to optimize disk performance by reducing fragmentation.

An antivirus is a type of protective software that is specifically designed to defend a computer against malicious software. It helps to detect, prevent, and remove viruses, malware, and other harmful programs from infecting the computer system. Antivirus software works by scanning files and programs on the computer, identifying any potential threats, and taking appropriate actions to neutralize them. It plays a crucial role in maintaining the security and integrity of a computer system by keeping it safe from various cyber threats.

Configuration is the correct answer because it refers to the process of choosing options in order to create a custom system. This involves selecting and adjusting various settings and parameters to tailor the system to specific requirements or preferences. System Repair, System Edition, and Customization do not accurately describe the process of choosing options to create a custom system.

The correct answer is "Port hub/Port". A port hub or port refers to a connector on the back of a computer or other device that allows for the connection of various peripherals or devices. It serves as an interface between the device and external devices such as USB devices, LAN cables, or other ports. This allows for the transfer of data or the connection of additional hardware to the device.

The correct answer is "Malicious Software". Malware is a combination of the words "malicious" and "software", referring to any software or program that is intentionally designed to harm or exploit computer systems, steal sensitive information, or disrupt normal operations. It includes various types of threats such as viruses, worms, Trojans, ransomware, spyware, and adware. "Malfunctioned Software" is not a valid explanation as it does not accurately describe the purpose or nature of malware.

The correct answer is OS, which stands for Operating System. An operating system is a software that manages and controls the allocation and use of programs and data on a computer. It provides a platform for other software applications to run, manages hardware resources, and enables communication between the computer and the user. Examples of popular operating systems include Windows, macOS, and Linux.

Maintenance refers to the process of testing, cleaning, and repairing equipment to ensure its proper functioning. It involves regular inspections and preventive measures to identify and resolve any potential issues before they become major problems. By performing maintenance, equipment can be kept in optimal condition, extending its lifespan and minimizing the risk of breakdowns or failures. Therefore, maintenance encompasses both testing and cleaning, making it the correct answer in this case.

ESD stands for Electrostatic Discharge, which refers to the sudden flow of static electricity between two objects. This discharge can cause damage to electronic components, including small parts of a computer. Therefore, an anti-static device is used to prevent ESD by grounding the static electricity and protecting the computer from potential harm. Direct current (DC) and alternating current (AC) are types of electric currents and are not directly related to the issue of static electricity damaging computer parts.

Anti-static devices are specifically designed to protect computers from static electricity. Static electricity can cause damage to computer components, such as the motherboard, RAM, or hard drive. These devices help to dissipate or neutralize static electricity, preventing it from damaging the computer. They can include wrist straps, mats, or grounding cords that are used to safely discharge any static electricity that may be present. By using anti-static devices, computer users can minimize the risk of static electricity-related damage and ensure the longevity and proper functioning of their computer systems.

Scandisk is a Windows utility that is used to check the hard disk for errors and correct any problems that are found. It scans the disk for bad sectors, file system errors, and other issues that could potentially cause data loss or system instability. By running Scandisk regularly, users can ensure the health and integrity of their hard disk, preventing potential problems and maintaining optimal performance.

The term "software" refers to programs and data that a computer uses. This includes operating systems (OS) like Windows or macOS, office suites like Microsoft Office, and various applications that perform specific tasks. Software is essential for the functioning of a computer as it enables users to interact with the hardware and perform various tasks.

The given correct answer is "Information System maintenance". This is because the explanation provided states that it is the routine updating of master files, such as adding and deleting employees and customers and changing credits limit and product prices. This indicates that it involves the maintenance and updating of the information system, which includes managing and modifying data in the system to ensure its accuracy and relevance.

Disk or file maintenance refers to the periodic reorganizing of disk files that have become fragmented due to continuous updating. Fragmentation occurs when files are stored in non-contiguous blocks on the disk, leading to slower access times. Disk or file maintenance helps to optimize disk performance by rearranging the fragmented files and consolidating them into contiguous blocks. This process improves data retrieval speed and overall system efficiency.

Power surge protectors are devices designed to protect computers from sudden power surges caused by intermittent power sources. These power surges can potentially damage computer components and lead to data loss. Power surge protectors work by diverting excess voltage away from the computer and preventing it from reaching sensitive electronic devices. They typically include surge suppression components and may also provide additional features such as power filtering and noise reduction. By using power surge protectors, computer users can ensure the safety and longevity of their devices by safeguarding them against unexpected power fluctuations.

Software or program maintenance refers to the process of updating and modifying application programs to meet changing information requirements. This can involve adding new functions, changing data formats, and ensuring that the software remains compatible with the evolving technology and user needs. It is an essential aspect of maintaining and improving the performance and functionality of software applications.
