When students type various messages, the messages will appear on the screen.

A keyboard is a device used for typing characters, including letters, numbers, and symbols. It is an input device that allows users to input text and commands into a computer or other electronic device. The other options, such as a mouse, a monitor, and a printer, are not specifically designed for typing characters.

The correct answer is "คีย์บอร์ด" (keyboard) because it is the primary input device that allows students to select commands from various menus on the screen. The monitor (จอภาพ) displays the menus and options, the speakers (ลำโพง) produce audio output, and the CD-ROM (ซีดีรอม) is a storage device that cannot be used to select commands.

The correct answer is "Monitor" because the question is asking for another term for "จอภาพ" which translates to "monitor" in English. A monitor is a display screen that allows users to view images, videos, and other visual content on a computer or electronic device.

The CPU (Central Processing Unit) can be considered as the "brain" of a computer. It is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system. Similar to how the human brain processes information and controls the body, the CPU controls and coordinates the various components of a computer. Therefore, the CPU can be likened to the "brain" of a computer.

The correct answer includes the devices that are commonly found in a computer setup. A printer, a computer case (also known as a tower or chassis), and a keyboard are all essential components of a computer system.

The speed of a computer's performance depends on the RAM (random access memory) because it determines how quickly the computer can access and process data. The more RAM a computer has, the faster it can perform tasks as it can store and retrieve data quickly. Therefore, the correct answer is "แรม" (RAM).

The correct answer is "เมาส์" (mouse). A mouse is not a device used for displaying output, but rather for inputting commands or controlling the cursor on a computer screen. The other options, "จอภาพ" (monitor), "ลำโพง" (speaker), and "เครื่องพิมพ์" (printer), are all devices used for displaying or producing output.

The correct answer is "Central Processing Unit." The CPU is the main component of a computer that performs most of the processing inside the computer. It is responsible for executing instructions, performing calculations, and managing data flow between different parts of the computer.

In order to watch a movie or listen to music, having speakers or headphones is necessary to hear the audio. Therefore, the correct answer is "ลำโพง" which translates to "speakers" in English.
