How does a computer work? Learn about transistors, logic gates, logic circuits, the CPU, memory, and the file system.

At a high level, all computers are made up of a processor (CPU), memory, and input/output devices. Each computer receives input from a variety of devices, processes that data with the …

As computer users, we're the most familiar with the parts of the computer that we interact with daily: the input and output devices.

Computers store long-term data in a different type of memory: external memory or secondary storage, like a hard drive or USB drive. We'll learn about that next.

Understand hardware, software, CPU, memory, storage devices, and key characteristics of a computer system.

At a high level, all computers are made up of a processor (CPU), memory, and input/output devices. Each computer receives input from a variety of devices, processes that data with the …

Computers also use other logic gates like NAND, NOR, and XOR. Each logic gate operates on inputs in a slightly different way; they output 1 and 0 in different situations.

Explore components, memory, microprocessors, and OS to understand how modern computer systems work and have evolved.

Now, let's look at a simple example of how input travels through a computer and becomes output. When you press a key on your keyboard, let's say the letter B, the keyboard converts the letter …
