Computer science 101
Every time you tap, click, or swipe on a device, you’re setting off a chain of invisible actions – all powered by code. Think of coding as giving detailed instructions to the most loyal assistant you can imagine: one who never gets tired nor strays from the task but needs you to be crystal clear and very precise. That’s essentially what coding is – a series of step-by-step directions that tell computers exactly what to do.
Whenever you send a message, snap a photo, or stream your favorite song, it’s code working behind the scenes to make sure everything runs smoothly. Whether it’s called software, a program, or an app, you’re ultimately talking about carefully crafted sets of instructions designed to make digital tasks happen. But even though this description may sound simple, writing code is rarely straightforward. Just like how spoken languages have tricky grammar rules, coding languages have their own quirks. And when something goes wrong – which it frequently does – you get what’s called a bug. Finding and fixing these bugs, a process known as debugging, is part detective work, part problem-solving, and a constant part of life for developers. Even the polished apps and websites you rely on every day are constantly being adjusted to handle bugs and proactively make improvements.
Diving deeper, you discover something even more fascinating: at its base level, every computer operates using just 1s and 0s – the binary language. A single 1 or 0 is called a bit. Put eight of them together and you have a byte. These tiny building blocks are what everything digital is made of, from numbers and letters to colors, photos, and videos. Whether you are talking about a character in a text, a pixel in an image, or a song you download, it is all just bits and bytes grouped into larger and larger bundles: kilobytes, megabytes, gigabytes, and beyond.
As you start to wrap your head around the fact that the digital world ultimately boils down to simple 1s and 0s, the next step is seeing how these bits – pun intended – actually turn into the powerful, interactive tools that shape our daily lives. This transformation happens through programming: turning raw code into meaningful actions, intelligent systems, and elegant solutions to complex problems. In the next section, we will explore how programming languages, control structures, and algorithms come together to drive everything from the apps on your phone to today’s most cutting-edge technologies.

Great app. Good selection of book summaries you can read or listen to while commuting. Instead of scrolling through your social media news feed, this is a much better way to spend your spare time in my opinion.
