不知道老師問啥，詢問了學長學姐，感覺學校考的都差不多記錄一下
A computer system consists of hardware system and software system. The hardware of the computer is usually divided into three major parts or three primary subsystems: the CPU, the memory subsystem, and the I/O subsystem.
The CPU performs many operations and controls computer. The memory subsystem is used to store program being executed by the CPU, along with the program’s data. The I/O subsystem allows the CPU to interact with input and output devices such as the keyboard and monitor of a personal computer. The components of the computer are connected to the buses
計算機系統由硬件系統和軟件系統組成。計算機硬件通常分爲三個主要部分或三個主要子系統：CPU、內存子系統和I/O子系統。
CPU執行許多操作並控制計算機。內存子系統用來存儲CPU正在執行的程序以及程序的數據。I/O子系統允許CPU與輸入和輸出設備（如個人計算機的鍵盤和顯示器）交互。計算機的部件與總線相連。.
Describe all the parts of an information system.
An information system typically consists of five parts: people, procedures, software, hardware, and data. Information systems are used by people in order to increase productivity. Procedures are rules or guidelines for people to follow when using software, hardware, and data. Software is a program that contains the step-by-step instructions that tell the computer how to do its work. Hardware consists of the physical equipment that processes the data to create information. Data consists of raw unprocessed facts, including text, numbers, images, and sounds.
描述信息系統的所有部分。
信息系統通常由五部分組成：人員、過程、軟件、硬件和數據。人們使用信息系統是爲了提高生產力。程序是人們在使用軟件、硬件和數據時要遵循的規則或指南。軟件是一種包含分步指令的程序，這些指令告訴計算機如何工作。硬件由處理數據以創建信息的物理設備組成。數據由未經處理的原始事實組成，包括文本、數字、圖像和聲音。
What is an operating system? Give two examples.
Operating systems are software that make the computer function. It is the layer that connects the hardware to the applications software. All programs that run on the computer do so in coordination with the operating system. Mainly, operating systems are programs that coordinate computer resources, provide an interface between the users and the computer, and run applications. Some examples of operating systems are Windows 7 and Mac OS X.
什麼是操作系統？舉兩個例子。
操作系統是使計算機工作的軟件。它是連接硬件和應用軟件的層。在計算機上運行的所有程序都是與操作系統協同工作的。操作系統主要是協調計算機資源、在用戶和計算機之間提供接口並運行應用程序的程序。操作系統的一些例子是Windows 7和Mac OS X。
