إمتحان تجريبي لمادة الحاسب الآلي

The statement "الحاسب الآلي جهاز الكتروني" translates to "The computer is an electronic device." This is a true statement as a computer is indeed an electronic device that processes data and performs various tasks.

The given statement is true. The hard disk drive is indeed a storage unit commonly used in computers. It is a non-volatile storage device that stores and retrieves digital information using magnetic storage and rotating platters. It is an essential component for storing and accessing data in computers, making it a crucial storage unit.

The correct answer is "إدخال" because the given options are "إدخال" (input), "إخراج" (output), "معالجة" (processing), and "تخزين" (storage). Out of these options, "إدخال" refers to the process of inputting or entering data into a computer system. Therefore, it is the most suitable option in the context of the given question.

The correct answer is "الشاشة" (the screen). This is because the question is asking for one of the output units, and the screen is a common output device that displays visual information to the user. The other options listed, such as the mouse, keyboard, and microphone, are input devices that allow the user to interact with the computer. Therefore, the screen is the correct answer as it is the device that displays the output information.

The given answer states that the exception to the input devices mentioned (mouse, keyboard, and microphone) is the "سماعة" which translates to "headphones" in English. This implies that headphones are not considered as an input device in this context.

The correct answer is "فلاشة النت" because it is the only option that does not refer to a type of storage device. The other options, such as "الفلاش مميوري" (flash memory) and "القرص الصلب" (hard disk), are all types of storage devices. "الكارت مميوري" (memory card) is also a type of storage device. However, "فلاشة النت" refers to a flash drive used for internet connectivity, not for storage purposes.

The statement "الشاشة من وحدات الادخال" translates to "The screen is an input unit" in English. However, this statement is incorrect. A screen or display is actually an output unit, as it is used to display information or output from a computer or device. Therefore, the correct answer is False.

The correct answer is "الادخال,الإدخال". This answer is correct because it correctly identifies the term "الادخال" and its alternative spelling "الإدخال" as the correct translation for the term "input" in Arabic. The given phrase "الماسح الضوئي من وحدات" translates to "scanner of input units" in English, indicating that the term "الادخال" is referring to the input units in this context.

The given statement is false. To turn on the device, we need to press the power button, not the restart button. The restart button is used to reboot or restart the device after it has already been turned on.
