Welcome to the world of computers! Have you ever wondered how your computer or gaming console works? Let’s dive into the fascinating world of hardware and software to understand how these amazing machines operate.
Erica Gomez is an engineering manager at Amazon, and she loves bringing her dog to work. Her job is to make sure that software is delivered smoothly. Jerome Holman is a Program Manager on Team Xbox, and he works on combining hardware and software to bring you the games you love on your Xbox.
When you look inside a computer or gaming console, you see parts like circuits, chips, wires, speakers, and plugs. These are all part of the hardware. Hardware is everything you can touch and see inside your device. It’s like the body of the computer.
Software, on the other hand, is the invisible part. It’s made up of programs or code that run on the machine. Software can be anything from apps and games to websites and tools that help companies like Amazon understand what customers want.
The central processing unit, or CPU, is the brain of the computer. It controls all other parts of the computer. The CPU receives commands that tell it what to do, like performing calculations or saving data. These commands are written in a special language called binary code, which uses only ones and zeros.
Binary code is stored in the computer’s memory, and the CPU reads these commands one by one to perform tasks. While binary code is the simplest form of software, most programming today is done using languages that are easier to understand, like English. For example, a simple command can draw a rectangle on the screen, which the CPU then translates into many binary commands.
When you’re using your computer to listen to music, browse the web, and chat with friends, it’s running many software programs at the same time. The operating system is like the manager that makes sure everything runs smoothly. It decides when programs run and how they interact with the hardware.
The operating system switches between programs quickly, sharing the CPU’s time. It also manages how software uses hardware, like when you install new programs or use input and output devices.
Computers can do incredible things, but their real power comes from you. By learning to code, you can solve problems and create software that turns your ideas into reality. This empowers you to build solutions that can make a difference in your life, your community, and the world.
So, whether you’re interested in creating games, designing apps, or exploring data science, understanding how hardware and software work together is the first step in your journey into the world of technology!
Explore the world of hardware by creating a simple circuit using a battery, wires, and a light bulb. This hands-on activity will help you understand how electricity flows through hardware components, similar to how it powers your computer.
Try your hand at coding by writing a simple program using a beginner-friendly language like Scratch or Python. This will give you a taste of how software is created and how it instructs hardware to perform tasks.
Identify and label different hardware components inside a computer or gaming console. This activity will help you recognize the physical parts that make up your device and understand their functions.
Learn the basics of binary code by converting simple text messages into binary and back. This exercise will show you how computers use binary to process and store information.
Simulate how an operating system manages multiple tasks by role-playing as the CPU and other components. This interactive activity will help you understand how software and hardware work together to run programs efficiently.
Sure! Here’s a sanitized version of the transcript:

Hi, my name is Erica Gomez, and I’m an engineering manager at Amazon. One of the best things about working in tech, especially at Amazon, is that I can bring my dog to work every day. My job involves ensuring that software is delivered efficiently, while my dog’s job is to nap under my desk.
My name is Jerome Holman, and I’m a Program Manager on Team Xbox. I have an exciting role that involves integrating hardware and software to provide you with the games you love on your Xbox. When you look inside a computing device, you see various components like circuits, chips, wires, speakers, and plugs. This is the hardware. However, the software, which consists of the programs or code running on the machine, is less visible. Software can include anything from apps and games to webpages and data science tools that my teams at Amazon use to analyze customer behavior.
So, how do hardware and software interact? Let’s start with a computer’s central processing unit, or CPU. The CPU is the main chip that controls all other parts of the computer. It consists of smaller components that handle specific tasks, such as performing calculations and managing data transfer. The CPU operates by receiving commands that instruct it on which components to use for particular tasks. For instance, an “add” command prompts the CPU to perform a calculation, while a “store” command saves the result in memory.
All commands can be represented in binary code, which consists of ones and zeros. This binary code is stored in memory, and the CPU processes these commands sequentially. This sequence forms a simple computer program. While binary code is the most basic form of software, modern programming is done using higher-level languages that resemble English. For example, a single command can be used to draw a rectangle on the screen, which is then converted into numerous binary commands that the CPU can understand.
When you’re listening to music, browsing the web, and chatting with friends, your computer runs multiple software programs simultaneously. The operating system manages how software interacts with the hardware. For instance, I contributed to the Windows operating system, which operates on most personal computers. The operating system controls the installation of new programs, determines when they run, and manages access to input and output devices.
When it seems like your computer is running many programs at once, the operating system is actually switching between them rapidly, sharing CPU time. Inside every computer, the operating system oversees software that controls the hardware. The software consists of commands made of binary code, which are electrical signals flowing through tiny circuits.
Computers have the potential to accomplish amazing tasks, but their true value comes from you. By learning to code, you can define problems and create software that brings your ideas to life, empowering you to build solutions that matter to you, your community, and the world.
