ICT Systems - GCSE

Explanation
Hardware refers to the physical components of a computer system, such as the motherboard, processor, memory, storage devices, and peripherals. It is different from software, which includes the applications and programs that run on the hardware. This definition highlights the correct understanding of hardware as the tangible parts of a computer system.

Explanation
A spreadsheet is a digital tool that is made up of cells, rows, and columns. These cells can contain various types of data such as text, numbers, and formulas. The rows and columns allow for organization and easy access to the data within the spreadsheet. Spreadsheets are commonly used for tasks such as data analysis, budgeting, and creating charts or graphs. They provide the ability to write, edit, and format text within the cells, making it a versatile tool for organizing and manipulating data.

Explanation
Input devices are devices that allow users to input data or commands into a computer system. The keyboard is an input device as it allows users to type and input text or commands into the computer. Speakers and display screens, on the other hand, are output devices as they provide output or display information from the computer system.

Explanation
A mouse is an input device. It allows the user to interact with a computer by moving the cursor on the screen and selecting objects or options. The movements and clicks made by the user on the mouse are sent as input signals to the computer, which then processes them and performs the corresponding actions. Therefore, a mouse serves as an input tool for providing commands and instructions to the computer.

Explanation
A computer system is mainly made up of hardware, software, and the data being used. Hardware refers to the physical components of a computer system, such as the processor, memory, and peripherals. Software refers to the programs and applications that run on the computer, allowing it to perform various tasks. The data being used refers to the information and files that are processed and stored by the computer system. Together, these three components work together to enable the functioning of a computer system.

Explanation
A microprocessor is a component that needs instructions because it is responsible for executing the instructions and performing the tasks assigned to it. Instructions provide the microprocessor with the necessary information and steps to carry out specific operations, such as performing calculations, accessing memory, or controlling other hardware components. Without instructions, the microprocessor would not know what actions to take or how to process data effectively. Therefore, it is true that a microprocessor requires instructions to function properly.

Explanation
ICT systems are used in aircraft for various purposes such as navigation, communication, weather monitoring, flight management, and entertainment systems for passengers. These systems rely on advanced technologies like computer networks, satellite communication, sensors, and software to ensure safe and efficient operation of the aircraft. ICT systems enable pilots to access real-time information, communicate with air traffic control and ground staff, and monitor the aircraft's performance. They also provide passengers with in-flight entertainment options, internet connectivity, and other services. Therefore, it is true that ICT systems are used in aircraft.

Explanation
The given statement is incorrect. CPU stands for Central Processing Unit, not controlled possessing unit. The CPU is the primary component of a computer that performs most of the processing inside the computer. It carries out the instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations.

Explanation
RAM stands for Random Access Memory, which is a type of computer memory that can be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This allows for faster data access compared to other types of memory. Therefore, the given statement "RAM stands for Random Access Memory" is true.

Explanation
A keyboard is an input device, not an output device. It allows users to input data, commands, and instructions into a computer or other electronic device. Output devices, on the other hand, are used to display or present information to the user, such as monitors or printers.
