Almost anywhere we go today, from malls to coffee shops, and even our homes is an intertwined web of wired, wireless, and cloud-based networks that access our personal data. In this course, you’ll dig into computer networks and their extensive capabilities. You’ll explore data exposure and how to mitigate threats, discuss the fundamentals of network design and layout, learn how cloud-based services store data, discover the differences between wired and wireless networks, and dream of possibilities as you explore fun network options like smart home systems. Let’s continue navigating the complex world of computer maintenance.

Mobility—it’s really our way of life! Our culture has gotten used to transporting laptops around with us; but as technology keeps advancing, most of us can now carry a very powerful computer in our pocket: the smartphone. While some people use their phones as a computer, others prefer to only use a few apps and see it as, well, a phone! Let’s look at how laptops and mobile devices function and how we can solve any issues we may run into when using them.

Take a look at your calendar or planner. Chances are, you have your time divided into different blocks—school, work, community events, sports practice, meals. As we go about our daily lives, weaving in and out of our homes, schools, stores, or restaurants, we’re constantly entering and exiting invisible territories: networks! Networks have become a part of our daily lives, even if we don’t realize it. Because we now live in a digitally connected world, knowing some basics about networks is crucial—not only so we can communicate efficiently but also so we can make choices that keep our data safe too.

When you input a search request into Google, a web server responds and provides the search results. When you log in anywhere, you enter your username and password, and a server authenticates your credentials—this means that it matches the username to the password. If it matches, access is granted; if it doesn’t, access is denied. When you access the internet, your internet service provider (ISP) has a server that authenticates the IP address of your computer to allow access. What’s the common denominator here? Servers! Let’s explore what servers are (hint: they are real, tangible things!), what they help us do, and how they work.

Networks are all around us: at home, work, school, the library, or the gym. And by now, we know a lot about how networks are designed and how the computers within networks function. But what is behind the walls, in the ceilings, and under the floors that connect the devices and make the network work? It’s time to learn about all of the devices that make these networks possible!

It seems that no matter what decade, whenever we envision the future, we think of flying cars. We’re still not there, but cloud computing has brought us to the horizon of modern data storage trends. Cloud computing has transformed industries like IT and education, but it has also changed the way we access data personally. In the cloud, we have infinite scalability and flexibility, so companies can grow more easily because they don’t have to build a huge new server room each time they expand. You’re probably familiar with some of the well-known cloud providers like Amazon Web Services, Google Cloud, IBM Cloud, and Microsoft Azure, but let’s learn about what goes on behind the scenes to give us remote access to data and services at lightning speed.

These days, it seems like everything is wireless, right? But, there are still advantages to using a wired network. Wired networks have dedicated bandwidths and fewer network traffic interruptions, so data arrives at its destination in a timely manner. They also have less interference from other devices, so they suffer fewer outages. That’s all important, but wired networks can also be fun! Want your fridge to tell you when you’re out of milk? It’s possible with wired networks. Let’s think deeper about the wired networks we rely on at home to see how they really work behind the scenes and start thinking about how we can incorporate wired devices into our dream smart home.

Chances are, you are more or less the tech expert in your household. You can help people set up computer equipment and troubleshoot issues that would frustrate most users. In a SOHO environment, we rely on our devices and wireless connectivity for just about everything we do. Knowing what these pieces of equipment are, what they do, and how they work is essential to keeping everyone in the home happy. After all, what’s life if you access the internet?

Identity theft is a multi-billion dollar business with most identity thieves going unpunished. How can we keep our personal data and that of our company safe in digital times? Security is an important aspect of being a responsible digital citizen. Some tactics we’re pretty familiar with already, but there are still quite a few more advanced security concepts that we’re in a prime position to handle now. You’ve designed networks, built computers, dreamed up an awesome smart home, and now it’s time to protect it all!
