What You Can Expect to Learn
Depending on the class, expect to learn about a few aspects that comprise the CSE branch. They can include computer networks, wireless networking, computer forensics, and network security.
The study of computer networks includes electronic data communication, equipment, software and hardware requirements, and the standard terminology. The curriculum covers configuring routers and internet protocols, the OSI (Open System Interconnection) model, and WAN and LAN networks.
Overall, these courses focusing on computer networks should provide you with operational knowledge to start building or managing networks. You also could learn about the best practices and troubleshooting skills.
Network security focuses on security risk and implementation for various operating systems. When learning about this, you’ll gain an understanding of potential threats and learn to apply security equipment and software.
A good wireless networking course should teach you about designing, managing, and troubleshooting networks. Plus, you learn also about wireless security and IP infrastructure.
This networking area covers computer forensic investigation and the various tools used in it. You’ll need an in-depth knowledge of operating systems, ethics, and data recovery methods. Computer forensics might be covered under a general network security course.
What to Look for in a Great Networking and Security Class
Regardless of your level of expertise, you should be looking for a few specific things when it comes to evaluating classes, including skills taught, instructor, and price.
At the beginner level, you will learn the basics of how computer networks work and the benefits they provide to users. You will explore the necessary expertise to plan and design these networks. In most cases, entry-level courses require a beginner’s knowledge of computers.
There are courses that prepare you for specific certifications like the Cisco CCNA 200-125. If you select a class like this, you would learn about data routing, IPv4 and IPv6 protocols, and switching on a particular network platform. If you want a more specialized education, you can find courses that focus on one element of computer networks.
Your instructor should have plenty of experience in the computer science industry. Computer networks are all about applying your knowledge to real-world situations. You are better off if your instructor has done this as their day-to-day job, and taken up teaching as a hobby or to pass on knowledge.
A good indication of a successful instructor is to look at their credentials before applying for a course. This, combined with ratings from past students, should give insight into whether they’re qualified to be teaching you about computer networks.
With online courses, the prices can vary greatly. Just because a course is expensive doesn’t automatically make it better than one offered in a sale, which is common for online learning centers. Look at your budget, determine how much you want to spend on a class, and evaluate your options.
