Basic Quiz On ICT System!

RAM stands for Random Access Memory, which is a type of computer memory that allows data to be read from and written to quickly. It is a volatile memory, meaning that it loses its data when the power is turned off. RAM is an essential component of a computer as it provides temporary storage for data that the processor needs to access quickly. Therefore, the given statement is true.

A computer system is mainly made up of hardware, software, and data being used. Hardware refers to the physical components of the computer system such as the central processing unit (CPU), memory, storage devices, and input/output devices. Software refers to the programs and instructions that tell the hardware how to perform tasks. Data being used refers to the information and files that are processed and manipulated by the computer system. Together, these components form the core elements of a computer system, allowing it to function and perform tasks efficiently.

A mouse is classified as an input device because it allows the user to interact with the computer by providing input. The movement and clicks of the mouse are interpreted by the computer as commands or instructions. This input is then processed by the computer to perform various tasks such as moving the cursor on the screen, selecting and opening files or applications, and navigating through software interfaces. Therefore, a mouse is primarily used for inputting data and commands into the computer system.

The hardware refers to the physical components of a computer, such as the motherboard, processor, memory, storage devices, and peripheral devices. It encompasses all the tangible parts that can be seen and touched. This includes both internal components and external devices that are connected to the computer. The hardware is essential for the functioning of a computer system and allows it to perform tasks and process data.

The keyboard is an input device because it allows the user to input data or commands into a computer or other electronic device. The user can type letters, numbers, or other characters on the keyboard, and the device will interpret and process the input accordingly. Unlike the display screen and speakers, which are output devices that display or produce information for the user, the keyboard is specifically designed for inputting data.

A microprocessor is indeed a component that requires instructions in order to perform its functions. Instructions are codes or commands that tell the microprocessor what operations to perform and how to process data. These instructions are typically stored in memory and fetched by the microprocessor to execute the desired tasks. Without instructions, a microprocessor would not know what actions to take and would be unable to carry out any meaningful operations. Therefore, the statement "A microprocessor is a component that needs instructions" is true.

A keyboard is an input device, not an output device. It is used to input data into a computer system by typing on the keys. The data entered through the keyboard is then processed and displayed as output on the computer screen or other output devices such as printers or speakers. Therefore, the statement "A keyboard is an output device" is incorrect.

ICT systems, which stands for Information and Communication Technology systems, are indeed used in aircraft. These systems play a crucial role in the modern aviation industry, enabling communication, navigation, surveillance, and other important functions. ICT systems help pilots and air traffic controllers exchange information, monitor aircraft systems, and ensure safe and efficient operations. They also facilitate passenger services, such as in-flight entertainment and connectivity. Therefore, the statement "ICT systems are used in air crafts" is true.

The given statement is false. 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 is responsible for executing instructions, performing calculations, and managing the flow of data within the computer system.

A spreadsheet is a software application that is made up of cells, rows, and columns. It is used to organize, store, and manipulate data in a tabular format. Each cell can contain text, numbers, or formulas, and they are organized into rows and columns to create a grid-like structure. This allows users to input and manipulate data, perform calculations, create charts and graphs, and analyze information efficiently. Spreadsheets are commonly used in various industries for tasks such as financial analysis, budgeting, data management, and project planning.
