But What Is The Internet?
The Internet is a computer network that interconnects hundreds of millions of computing devices throughout the world. The Internet (or internet) is a global network of interconnected computer networks that communicate using the Internet protocol suite (TCP/IP). It is a “network of networks” made up of local to global private, public, academic, business, and government networks linked by a variety of electronic, wireless, and optical networking technologies.
This course’s goal is to give you a modern introduction to the dynamic field of computer networking, providing you with the principles and practical insights you’ll need to understand not only today’s networks but also tomorrow’s.
This course provides an introduction to computer networking and the Internet. To see the forest through the trees, our goal here is to paint a broad picture and set the context for the rest of your journey in the world of computer networking. In this introductory course, we’ll cover a lot of ground and discuss a lot of the components of a computer network without losing sight of the big picture.
Most networking books and courses are filled with acronyms that put your brain to sleep. They frequently overlook the fact that you are just starting out in the world of networking. This course is not meant to be used as a reference. This course is designed to ensure that when you read a networking reference book or take a networking course, the texts do not feel like hieroglyphs.
Why Should You Learn Networking?
IT and networking professionals are in short supply all over the world. According to the US Department of Labor, employment of network and computer systems administrators will increase by 31% between 2014 and 2024. The story is the same in every country and on every continent. Organizations and institutions rely on a workforce with digital skills to make the most of mobile devices, cloud computing, social media, and big data as they invest in these technologies. At the moment, the number of people working and studying technology simply cannot keep up with the expected demand. Individuals who choose to supplement their studies or professional skills with networking discover new opportunities in today’s digital economy.
Networking begins with fundamental logic and connections. The only prerequisite for the Networking course is a desire to learn about technology as well as basic math and reading comprehension. If you are in or have completed high school, you most likely have the necessary skills to begin a networking career.
Who Is This Course Intended For?
You may need to learn networking for a job, a class (such as CCNA), or simply because you believe it is about time to learn the difference between a switch and a router.
You want to learn, understand, and remember how to run an industrial-strength packet sniffer, configure a Domain Name System server, and configure routing protocols such as EIGRP.
You want to work as a network systems administrator but don't know where to begin.
Computer networking careers include network administrator, network technician, and network engineer. Other job titles in computing networking include systems engineer and systems administrator. The field is expanding as a result of increased demand for enterprise businesses to become fully digital, as well as more cloud computing opportunities, among other factors.
What Do Network Engineers Do?
Network engineers, also known as network administrators, are employed by a company’s information technology department. They are in charge of ensuring that their company’s computer systems and network hardware are running smoothly. This is accomplished by installing new hardware, performing diagnostics, and installing routine software updates as they become available. They are also expected to take preventative measures to safeguard network security against malware and other potential threats.
How To Become A Network Engineer?
It takes time and determination to become a network engineer. There is no single direct path to becoming a network engineer, but there is a recommended sequence for achieving your career objectives. A networking professional must understand the following core concepts in computer networking:
- LAN vs. WAN
- Clients and servers
- DNS lookup & IP addresses
- Default gateway
- Routers and switches
These topics will be thoroughly discussed(not necessarily in this sequence).
The Structure Of The Course
In this course, we’ll structure our overview of computer networks as follows. After introducing some fundamental terminology and concepts, we’ll look at the basic hardware and software components that comprise a network.
The core of a computer network will then be examined, including the links and switches that transport data, as well as the access networks and physical media that connect end systems to the network core. We’ll discover that the Internet is a network of networks, and we’ll discover how these networks communicate with one another.
We’ll use pictures because your brain is wired for visuals rather than text. And when we combine text and images, we will embed the text in the images because your brain works better when the text is within the thing to which the text refers, rather than in a caption or buried in the text somewhere.
We will say the same thing in different ways, using different media types, and engaging multiple senses to increase the likelihood that the content will be coded in more than one area of your brain.
Because your brain is tuned to pay more attention when it believes you’re in a conversation rather than passively listening to a presentation, this course is designed in a personalized, conversational style. Even when you’re reading, your brain does this.
Now let us get started!
