Explanation
RAM stands for Random Access Memory, which is a type of computer memory that is used to store data that is currently being used by the computer. It is considered temporary memory because its contents are erased when the computer is powered off or restarted. RAM is used to store data that is actively being processed by the computer's CPU, allowing for faster access and retrieval of information compared to other types of storage. Therefore, the statement "RAM is temporary memory" is true.

Explanation
The statement is incorrect. RAM, or Random Access Memory, actually helps computers operate faster. It is a type of computer memory that allows data to be accessed quickly by the computer's processor. The more RAM a computer has, the more data it can store temporarily, which can lead to faster performance and multitasking capabilities. Therefore, RAM does not make computers operate slower.

Explanation
The statement is true because just like a basement, a hard drive is used to store and keep things that are not currently needed but may be required in the future. A hard drive acts as a storage space for all the data, files, and programs on a computer, allowing users to access them whenever necessary. Similar to a basement where items are stored for later use, a hard drive serves as a digital storage space for easy retrieval and utilization of stored information.

Explanation
The analogy compares the processor to a butler, suggesting that the processor is responsible for coordinating and managing tasks, just like a butler helps complete tasks for someone. This implies that the processor plays a crucial role in making things work together efficiently, similar to how a butler ensures that everything runs smoothly in a household. Therefore, the statement "The processor is like the butler who makes things work together and helps complete tasks for you" is true.

Explanation
When a computer is turned off, the power supply to the temporary memory (RAM) is cut off, causing the stored data to be lost. This is because RAM is a volatile type of memory that requires a constant flow of electricity to retain its contents. Therefore, it is correct to say that temporary memory in a computer is erased when the computer is turned off.

Explanation
This picture is an example of a mouse, which is an input device. A mouse is used to interact with a computer by moving the cursor on the screen and clicking on different elements. It provides input to the computer by transmitting the user's commands and actions.

Explanation
The picture shows a monitor, which is a visual display device. Monitors are commonly used as output devices to display information from a computer or other electronic devices.

Explanation
The picture shows a printer, which is a device used to produce hard copies of documents or images. As it generates printed output, the printer is considered an output device.

Explanation
This statement is true because a modem is indeed a type of communication device that enables data transmission over cable or telephone lines. It acts as a bridge between the user's device and the internet service provider, converting digital signals from the device into analog signals that can be transmitted over the network and vice versa. Modems are commonly used to establish internet connections in homes and businesses.

Explanation
The CPU, or central processing unit, is indeed considered the brain of the computer. It is responsible for executing instructions and performing calculations, making it a crucial component of any computer system. All data and tasks that occur on a computer pass through the CPU, which processes the information and carries out the necessary operations. Therefore, the statement "The CPU is the brain of the computer and everything that happens goes through this brain" is true.

Explanation
The statement is true because all the listed devices are examples of input devices. Input devices are used to input data or commands into a computer system. Keyboards and mouse devices are commonly used for typing and navigating on a computer. Microphones are used to input audio, scanners are used to input physical documents or images, and digital cameras and video cameras are used to input visual data. Therefore, all the devices listed are examples of input devices.

Explanation
The motherboard is a crucial component of a system unit as it houses the electronic chips and provides connections to peripherals. It acts as a central hub, allowing communication between various hardware components such as the processor, memory, and storage devices. Without a motherboard, the system unit would not be able to function properly. Therefore, the statement is true.

Explanation
Output devices are devices that are used to display or present the results of processing to the user in a format that can be easily understood. Monitors, printers, and speakers are all examples of output devices as they provide visual or auditory information to the user. Therefore, the statement that output devices deliver the results of processing in a form that people can understand is true.

Explanation
The statement is true because hard disk drives, floppy disk drives, CD-ROM drives, and DVD-ROM drives are all examples of storage devices. These devices are used to store and retrieve data, allowing users to save and access files and programs. Hard disk drives are commonly used in computers to store large amounts of data, while floppy disk drives, CD-ROM drives, and DVD-ROM drives are used to read and write data onto removable media. Therefore, the given answer is true.

Explanation
This item is an example of a scanner, which is an input device used to convert physical documents or images into digital format. Scanners are commonly used in offices and homes for tasks such as scanning documents, photos, or artwork. They capture the information from the physical item and transfer it to a computer, where it can be edited, saved, or printed. Unlike printers, hard drives, or monitors, scanners are specifically designed for inputting physical items into a digital format.

Explanation
The correct answer is "Storage Device, Hard Drive." A hard drive is a type of storage device that is used to store and retrieve digital information. It is commonly used in computers to store operating systems, software applications, and user data. RAM, on the other hand, is a type of memory device that is used to temporarily store data that is actively being used by the computer. Therefore, the answer "Storage Device, Hard Drive" is the correct choice as it accurately identifies the device type and its specific name.
