The power supply component is responsible for providing a steady supply of electricity to all other components in the computer. When the computer is plugged into a power socket, the power supply takes in the electricity from the cord and converts it to the appropriate voltage levels required by the various components. It also contains a transformer, which helps regulate the flow of electricity and protect the computer from power surges. Without a functioning power supply, the computer would not receive the necessary power to operate.

The correct answer is "Backup and Restore." This option is the most suitable explanation for a multilevel storage facility to ensure continued data security in case of component or sub-system failure. Backup and restore processes involve creating duplicate copies of data and storing them in different locations, ensuring that even if one component or sub-system fails, the data can still be accessed and restored from the backup. This helps to safeguard against data loss and maintain data security in case of any failures.

Disk defragmentation is a process that reduces the amount of fragmentation in file systems. Fragmentation occurs when files are stored in non-contiguous blocks on a hard drive, leading to slower access times. Disk defragmentation rearranges the fragmented files and consolidates them into contiguous blocks, improving the overall performance of the system. This process helps to optimize disk space and enhance the efficiency of file retrieval, making it the correct answer in this context.

This question is asking about the kind of maintenance that involves removing unwanted files and performing disk defragmentation to improve computer performance. This type of maintenance is commonly referred to as "Personal Computer Maintenance."

An uninstaller is a type of application software that is specifically designed to remove all or parts of a specific other application software. It allows users to easily and completely remove unwanted programs from their computer systems. This can be useful for freeing up disk space, improving system performance, and resolving compatibility issues.

File compression is the correct answer because it refers to the process of encoding information using fewer bits. This process reduces the size of files, making them easier to store, transmit, and manage. By compressing files, unnecessary data and redundancies are removed, resulting in a smaller file size without losing important information. This can be achieved through various compression algorithms, such as ZIP or RAR, which are commonly used to compress files and folders.

A search utility is a software program that searches a database and gathers and reports information that contains or is related to specified terms. This tool is specifically designed to help users find specific information within a database or system. It allows users to input specific search terms and retrieves relevant data or files based on those terms. Unlike other options listed, such as personal firewall, antivirus, or backup, a search utility focuses solely on searching and retrieving information rather than providing security or data protection features.

A media player is a term typically used to describe computer software for playing back multimedia files. It is a program or application that allows users to play various types of media such as audio, video, and images on their devices. Unlike the other options listed (VHS, 8 Track, and Record Player) which are physical devices used for playing specific types of media, a media player refers specifically to software used on computers or digital devices for playing back multimedia files.

The correct answer is Operating System because it is the software that supports a computer's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. The operating system acts as an intermediary between the hardware and the user, providing a platform for other software to run on the computer. It manages resources, provides security, and allows users to interact with the computer system.

Internet filters are commonly referred to as "content control software" because they are designed to restrict what websites a user can visit on their computer. These filters allow users to block or limit access to certain websites or types of content, providing a safer and more controlled internet browsing experience. Internet filters are commonly used by parents, schools, and organizations to protect users from inappropriate or harmful content and to promote responsible internet usage.

Disc burning refers to the process of assembling source material, such as video, audio, or other data, into the correct logical volume format to be recorded on an optical disc. This involves creating a disc image, organizing the data, and writing it onto the disc using a disc burner. It is a common method for creating DVDs and Blu-ray discs, allowing users to store and share their media files.

The motherboard is the correct answer because it serves as the base of operations for the brains of a computer. It is responsible for connecting and coordinating all the essential components of a computer system, including the CPU, memory, storage devices, and other peripherals. The motherboard provides the necessary electrical connections and pathways for data transfer between these components, making it a literal foundation for many of the other elements inside a computer.

A file manager is a computer program that provides a user interface to work with file systems. It allows users to perform various operations on files, such as creating, opening, editing, viewing, printing, playing, renaming, moving, copying, deleting, searching, and modifying file attributes, properties, and file permissions. The files are typically displayed in a hierarchical structure, making it easy for users to navigate through their file system and manage their files efficiently.

An optical drive is a device that uses lasers to read or write CD's or DVD's. It is commonly found in computers and other electronic devices. The laser technology allows the drive to accurately read the data stored on the discs, or to write new data onto them. This makes it possible to play music or movies, install software, or back up files onto optical discs. The other options listed - RAM, CPU, and Hard Drive - are all important components of a computer, but they do not specifically relate to the function of reading or writing CD's or DVD's.

A hard disk is a storage device that consists of either a series of thin platters or a solid-state flash drive. It is used to store information using magnetic recordings or flash memory technology. Unlike optical drives, which use lasers to read and write data on optical discs, hard disks have no moving parts. This makes them more durable and less prone to mechanical failures. Therefore, the correct answer is hard disk.

The correct answer is CPU. The CPU, or Central Processing Unit, is the computer's brain and is responsible for performing calculations and executing instructions necessary for the computer to function. It is a microprocessor that contains millions of tiny transistors. RAM, Hard Disk, and Optical Drive are all components of a computer, but they do not perform the same functions as the CPU.

RAM, or Random Access Memory, is a type of computer memory that allows computers to read from and write to it. It holds the data of the software being used, allowing for quick access and retrieval of information. RAM plays a crucial role in speeding up the computer's performance by providing temporary storage for data that the CPU needs to access frequently. Unlike a hard disk, which is a non-volatile storage device, RAM is volatile and loses its data when the computer is turned off.
