How computers take information as input then process store and output information?

Input devices accept data in a form that the computer can use; they then send the data to the processing unit. The central processing unit executes computer instructions that are specified in the program. Output devices show people the processed data-information in a form that they can use.

What is the most basic level of a computer?

At the most basic level, a computer is a device consisting of three pieces: o A processor to interpret and execute programs o A memory to store both data and programs o A mechanism for transferring data to and from the outside world.

How do computers work electrons?

An electronic computer computes by moving electrons around, so the physical restrictions of an electron moving through matter determine how fast such computers can run. “The wires in an electronic computer are like full hoses: they are already packed with electrons.

How did the first computer work?

Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes.

How does a computer store data?

Data is stored as files – the computer equivalent of files stored in a filing cabinet. Files are stored in folders and folders are stored within drives. Data is copied from the computer’s main memory (random-access memory or RAM), and then written to the hard disk.

How does input output and storage device work?

Input, used to interact with, or send data to the computer (mouse, keyboards, etc.) Output, which provides output to the user from the computer (monitors, printers, etc.) Storage, which stores data processed by the computer (hard drives, flash drives, etc.)

How does a computer work for Class 2?

A computer is an electronic machine which is used to do different kinds of work. A computer is a fast, accurate and multitasking machine. A monitor is a screen which displays what a computer is doing. A CPU stands for Central Processing Unit which controls the other parts of a computer.
