Hardware you touch; software you can't. Together, they run your computer.
Every computer has four key parts: CPU, RAM, inputs, and outputs.
The bus moves data between components, like a digital highway
The motherboard connects all components, making communication possible.
RAM temporarily stores data for fast access while working.
ROM permanently stores instructions to start your computer.
Monitors, printers, and speakers let us see, hear, and touch computer results.
Monitors come mainly as LCD or LED types for different visuals.
Hardcopy is printed, softcopy is digital. Both have unique advantages.
From kilobytes to zettabytes, data storage units measure digital size
Создано более 30 миллионов раскадровок
