แบบทดสอบที่ 2 เรื่อง หลักการทำงานของคอมพิวเตอร์

The given question asks for an item that is not a storage device. A hard drive, flash drive, and external hard drive are all examples of storage devices as they are used to store data. However, a mouse is not a storage device. It is an input device that is used to control the movement of the cursor on a computer screen. Therefore, the correct answer is "Mouse".

The correct answer is "เครื่องปริ้นเตอร์" because a printer is a device that produces output in the form of printed documents or images. The other options listed (mouse, scanner, and keyboard) are input devices, which are used to input data into a computer system.

The given options are all components of a computer system. Input devices are used to input data into the computer, output devices are used to display or output information from the computer, and memory is used to store data and instructions. The central processing unit (CPU) is responsible for executing instructions and performing calculations. Therefore, the correct answer is "Central Processing."

The correct answer is "หน่วยความจำหลัก" because RAM (Random Access Memory) is the main memory of a computer system where data and instructions are stored temporarily for quick access by the CPU (Central Processing Unit). It is a volatile memory that is used to hold data that is currently being processed by the CPU. The other options, such as "หน่วยความจำสำรอง" (secondary memory), "หน่วยประมวลผล" (processing unit), and "หน่วยแสดงผลข้อมูล" (data display unit), are not the correct answers as they are not directly related to the main memory of a computer system.

Input devices are used to receive data and instructions from the user or other devices and send them to the computer for processing. This includes devices such as keyboards, mice, scanners, and microphones. These devices allow the user to input data or give commands to the computer.

The correct answer is "เมาส์ คีย์บอร์ด เครื่องอ่านบาร์โค๊ด". This is because a mouse, keyboard, and barcode reader are all devices that are used to input information into a computer or system.

The correct answer is "Output Devices". Output devices refer to the components or devices that display or present the processed information or data to the user. These devices include monitors, printers, speakers, projectors, etc. They are responsible for presenting the results or output of the processing performed by the computer system.

The correct answer is 4 ส่วน because the question is asking for the total number of parts in a computer system. The options provided are the possible answers, and 4 is the correct one.

The correct answer is "Central Processing Unit". CPU stands for Central Processing Unit, which is the main component of a computer system responsible for executing instructions and performing calculations. It is often referred to as the "brain" of the computer, as it carries out the majority of the processing tasks.

The current generation of processors is Intel Core i7.
