Computer A Smart Machine

A computer runs on electricity because it requires electrical power to function. Electricity is used to power the components of a computer, such as the motherboard, processor, and memory. Without electricity, the computer would not be able to perform any tasks or operations. It is the primary source of energy that allows the computer to process data, run programs, and perform various functions.

A car runs on fuel because it has an internal combustion engine that requires gasoline or diesel to generate power. This fuel is burned inside the engine, creating a series of controlled explosions that drive the car's pistons and ultimately turn the wheels. Without fuel, the car would not have the energy needed to operate and move.

The statement "An aeroplane is a machine" is true because an aeroplane is a man-made object that is designed and built to fly. It is a complex mechanical device that uses various systems and components to achieve flight. It relies on engines, wings, control surfaces, and other mechanisms to generate lift, propulsion, and control. Therefore, it can be classified as a machine.

The correct answer is "Easy" because machines are designed to simplify and automate tasks, making them easier for humans to complete. Machines can perform repetitive or physically demanding tasks, saving time and effort for humans. Additionally, machines can enhance productivity and accuracy, further contributing to making work easier.

A washing machine does not run on fuel. It runs on electricity.

This statement is false because machines are designed to save our time and make tasks more efficient. Machines can automate repetitive tasks, perform complex calculations, and complete work faster than humans. They can also handle heavy lifting and perform tasks that would be difficult or time-consuming for us. Overall, machines are created to save time and increase productivity in various industries and daily life activities.

The computer saves our time by automating tasks that would otherwise take a long time to complete manually. It can perform calculations, process data, and execute commands much faster than humans, allowing us to accomplish tasks more efficiently. Additionally, computers enable us to access information instantly, reducing the time needed to search for and retrieve data. Overall, the computer's speed and efficiency contribute to time-saving in various aspects of our lives and work.

The computer never gets tired. This means that unlike humans, computers do not experience fatigue or exhaustion. They can continuously perform tasks without needing rest or breaks. Computers are designed to operate efficiently for long periods of time without getting tired, making them reliable and consistent in their performance.

A computer works very fast because it can process and execute instructions at a speed that is much faster than human capabilities. It can perform complex calculations, retrieve and store large amounts of data, and execute multiple tasks simultaneously. This is due to the advanced hardware and software components that are designed to optimize speed and efficiency in computing operations.
