Therefore, the statement "A red, wavy underline in a document means a possible spelling error" is true.

A UPS (Uninterruptible Power Supply) is a device that provides backup power to a computer or other electronic devices when the main power supply is interrupted or fails. It ensures that the computer continues to work for a certain period of time, allowing the user to save their work and safely shut down the system.

Computer parts that can be physically touched are referred to as hardware. Hardware includes components such as the central processing unit (CPU), memory, storage devices, input and output devices, and other physical components that make up a computer system. Systems, platforms, and software are not physical components and do not fall under the category of hardware.

A piece of personal information refers to information that identifies or relates to an individual. In this case, the only option that fits this definition is "Your home address." This information is specific to an individual and can be used to locate or contact them, making it personal and sensitive. The other options, such as the temperature outside or the number of students at a dance, do not pertain to an individual's personal identity or privacy.

Opening e-mails from people you know is a safe practice when online because it helps to avoid potential phishing scams or malicious attachments. By only opening e-mails from trusted sources, you reduce the risk of falling victim to cyberattacks or having your personal information compromised. It is important to exercise caution and verify the sender's identity before opening any e-mail, especially if it contains suspicious or unexpected content.

The "Save As" command allows the user to save a file with a new name or at a different location. This command is useful when the user wants to create a copy of the file or save it in a different format without modifying the original file. The "Save" command, on the other hand, simply saves the file with its current name and location. The "Close" command is unrelated to saving a file and is used to close the current window or application.

A keyboard is classified as an input device because it allows the user to input data or commands into a computer system. The user can type characters, numbers, and special symbols on the keyboard, which are then processed by the computer. The keyboard does not produce any output on its own, but instead sends the input to the computer for processing and generating an output. Therefore, the correct answer is "Input".

A hand-held input device that controls the insertion point location is a mouse. A mouse is a common peripheral device used to move the cursor on a computer screen and select or manipulate objects. It allows users to interact with graphical user interfaces and navigate through different applications and documents by moving the mouse across a flat surface. The mouse typically has one or more buttons that can be clicked to perform various actions, such as opening files or selecting text.

The correct answer is "Control Unit" because in computer architecture, the control unit is responsible for coordinating and controlling the operations of the computer's hardware components. It manages the execution of instructions, fetches data from memory, and directs the flow of data between various components. The control unit plays a crucial role in ensuring that instructions are executed correctly and in the correct sequence.

Emoticons are generally considered informal and casual forms of communication. Therefore, it is appropriate to use them in e-mails to friends, where the tone is typically more relaxed and personal. In book reports for school or letters to the principal, however, a more formal and professional tone is expected, making the use of emoticons inappropriate.

The statement is false because a speaker is an output device, not an input device. Input devices are used to input data or commands into a computer, while output devices are used to display or output information from a computer. A speaker is used to output sound or audio, making it an output device.

Software refers to the set of instructions that tells the hardware in a computer what to do. It is a collection of programs, data, and instructions that enable a computer to perform specific tasks.
