A modem is a device that allows computers to communicate through telephone lines. It converts digital signals from the computer into analog signals that can be transmitted over telephone lines, and vice versa. This enables the computer to connect to the internet or to communicate with other computers over a telephone network. Modems are essential for establishing a connection between a computer and the internet service provider, allowing data to be transmitted and received effectively.

A monitor is a device that displays text and images generated by a computer. It is the screen that allows users to visually interact with the computer system. The monitor receives signals from the computer's graphics card and translates them into visual output. It is an essential component of any computer setup as it enables users to view and interact with the information and content being generated by the computer.

RAM stands for Random Access Memory, which is a type of computer memory that is used to store data that is being actively used by the computer. It is called "temporary memory" because its contents are erased when the computer is powered off. RAM allows the computer to quickly access and manipulate data, making it an essential component for running programs and performing tasks. CMOS, ROM, and POOP are not correct answers as they refer to different components or types of memory in a computer.

The correct answer is "any part of the computer you can see or touch." This answer accurately defines hardware as the physical components of a computer that are tangible and visible. It includes devices such as the monitor, keyboard, mouse, CPU, memory, and storage devices. Hardware is distinct from software, which refers to the programs and instructions that run on the computer.

A surge protector is designed to protect electronic devices from sudden surges or fluctuations of power. It acts as a barrier between the device and the electrical outlet, preventing any excess voltage from reaching the device. This is important because power surges can cause damage to sensitive components of electronic devices, such as CPUs, modems, and mice. By using a surge protector, the device is shielded from these power fluctuations, ensuring its safety and longevity.

The correct answer is "a set of instructions that tells a computer which program to run". This is because software refers to the programs and instructions that enable a computer to perform specific tasks. It includes a collection of instructions that guide the computer on what actions to take and which programs to execute. Therefore, software acts as a set of instructions that direct the computer's operations.

Random Access Memory (RAM) is a type of computer memory that is used to temporarily store data that the computer is actively using. It allows the computer to quickly access and manipulate this data, making it essential for the smooth functioning of a computer system. Unlike Read Only Memory (ROM) which stores permanent data, RAM is volatile and loses its contents when the computer is turned off. Therefore, RAM is the correct answer for the given question.

The cursor is a graphical representation on a computer screen that indicates the position where the next insertion or typing will occur. It is typically represented as a blinking vertical line or a small arrow. The cursor allows the user to interact with the computer by indicating where the input or action will take place. In this context, the cursor marks the position of the next insertion point, indicating where the user can input or type something.

The keyboard is the correct answer because it is a device that allows users to input data into a computer. It has a set of keys, including letters, numbers, and symbols, which can be pressed to enter information. The keyboard is an essential input device for typing text, entering commands, and navigating through various applications and programs on a computer.

A device that is connected directly to the computer is called a peripheral. Peripherals are external hardware devices that are connected to the computer to enhance its functionality or provide additional features. Examples of peripherals include printers, scanners, keyboards, and mice. These devices are connected to the computer via ports or cables and can be easily added or removed as needed.

An output device is a hardware component that allows a computer to communicate with the user by presenting information or data generated by the computer. It is responsible for putting information out from the computer, such as displaying text or images on a monitor, printing documents on a printer, or playing audio through speakers. Output devices enable users to receive and interpret the processed data from the computer, making them an essential part of the computer system.

An operating system is a type of software that controls the overall activity of a computer and tells the different hardware components how to work together. It manages tasks such as memory allocation, file management, and device communication, providing a platform for other software applications to run on the computer. The operating system acts as an intermediary between the user and the computer hardware, ensuring that all the hardware components function smoothly and efficiently.

The left hand home row keys on a standard QWERTY keyboard are ASDF. These keys are positioned in the middle row of the keyboard and are meant to be the default resting position for the fingers of the left hand. By placing the fingers on these keys, typists can easily reach the surrounding keys without having to move their hand too much, which helps improve typing speed and accuracy.

The right hand home row keys on a standard QWERTY keyboard are "jkl;". These keys are positioned under the right hand's resting position when touch typing. The "j" key is placed under the right index finger, the "k" key under the right middle finger, the "l" key under the right ring finger, and the ";" key under the right pinky finger. These keys serve as a reference point for proper finger placement and help maintain typing accuracy and speed.

The shortcut key "ctrl A" is used to select all the content in a document, file, or webpage. By pressing these keys simultaneously, you can quickly highlight and select all the text or objects present, allowing for easy editing, copying, or deleting of the selected items. This shortcut is commonly used in various applications and operating systems to streamline the selection process and improve productivity.

When the computer turns off, the RAM loses all the data stored in it. This is because RAM is a volatile type of memory, meaning it requires constant power to retain information. When the power is cut off, the electrical charges holding the data in RAM dissipate, causing the data to disappear. Therefore, the correct answer is that the RAM disappears when the computer turns off.

ROM stands for Read Only Memory, which refers to a type of computer memory that is permanent and cannot be changed. Unlike other types of memory, such as RAM, ROM retains its data even when the computer is turned off. It is commonly used to store firmware and software instructions that are essential for the computer to boot up and perform basic functions. Since ROM is non-volatile, it is ideal for storing critical data that should not be altered or erased. Therefore, the given answer accurately describes the meaning of ROM.
