Answer :
Computer: A computer is an electronic device that processes data, performs computations, and executes programs. It consists of hardware components such as a processor, memory, and storage, and is capable of running a wide range of software applications. Computers are used in various fields for tasks like word processing, internet browsing, data analysis, and more.
Data Processing: Data processing involves the collection, manipulation, and presentation of data to extract meaningful information. It includes tasks such as inputting data, processing it through algorithms or software, and producing output in a useful format. Data processing can be manual or automated and is essential for decision-making in businesses and scientific research.
Data Transformation: Data transformation is the process of converting data from one format or structure into another. This step is often part of data processing and is crucial for ensuring that data is compatible with different systems or applications. Transformation might involve tasks such as aggregating, filtering, enriching, or reformatting data.
Booting: Booting is the process of starting up a computer's operating system when it is powered on. During booting, the computer performs diagnostic tests, loads system files, and prepares the system for use by initializing hardware and software components.
Warm Booting: Warm booting, also known as a soft reboot, involves restarting a computer without turning off the power completely. This can be done by selecting the 'Restart' option in the operating system. It is often used to apply system updates or resolve software issues without going through a full shutdown.
Cold Booting: Cold booting, or hard rebooting, refers to the process of starting a computer from a completely powered-down state. It involves turning the computer off and then back on. This method is used when the system is unresponsive or after hardware changes, as it completely resets the system's state.
