Wi-Fi networks have been misunderstood by much of the IT community since their inception. Even the reasons for this misunderstanding are kind of hard to understand. The result has been that myths about 802.11 (better known as Wi-Fi) networks have grown almost as fast as the technology itself. In this web seminar, we'll examine 11 common Wi-Fi myths and explore ways to use correct information to make your networks scalable, secure and satisfying for your users.

A local area network (LAN) provides a path of communication, allowing the delivery of packets of data, voice, or video originating from the sender (logical source address) to the receiver (logical destination address). Ethernet is the most common LAN used. As you start to learn about networking, remember that communication and the movement of large numbers, whether it is people, cars, mail, or network traffic, have a commonality. Everything you know and use in your daily life can be compared to the way traffic moves.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicate ideas as well as create new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

With the onset of the Digital Age, IT professionals today are hit with a tsunami of changes! "By 2018, adoption of mobile, social, cloud, analytics will redefine 90% of IT roles" according to IDC 2014 Predictions: CIO Agenda. Large organizations are eliminating silos. Small and medium organizations are outsourcing technology services. Digital natives have entered the workforce. New roles will emerge as new ways of doing business are introduced and as old technology fades away. Today's IT professionals must adapt, and a new set of skills is in order. Join Pranav Shah, Manager of Information Technology and Security at Sony Canada, and Pam Maguire, Business Development Manager, Global Knowledge, for a 60 minute webinar on how to future-proof your IT career in the Digital Age. You will learn about how IT roles are changing, what organizations are looking for, and what you can do now to be ready.

Nasser El-Batal will walk you through the most useful, recognized, and mandated ITSM best practices in the industry: TOGAF, COBIT and ITIL®. He will highlight the benefits of integrating them into a single implementation program to avoid project disaster. Discussions are focused on "Getting Your House in Order" and how to establish your own organization-specific business transformation program, while increasing your organization maturity.

You will learn how many organizations approach change management as compared to how best practices dictate that change management should work. Global Knowledge instructor and ITIL Expert Michael Scarborough will fill you in on the purpose of change management and the difference between change management and change tickets. He will provide a high-level guide for establishing a change management process that uses real-world examples as its basis.

This certification and exam guide discusses the various ITIL® certifications and what they might mean to you, your organization, and your career, as well as provide important test-taking tips for the ITIL certification exams. ITIL certifications help individuals validate their ability to demonstrate skills from a foundational to a mastery level of IT service management. ITIL certification can often be a key differentiator in the marketplace as well.

Whether you’re a beginner or intermediate Python developer, you’ll want to keep this guide close to your keyboard and Python editors. In it, you’ll find sample use cases for many of the most common language constructs and tasks that you’ll likely need to perform, such as reading a file or working with a database.

The driver behind 802.11n is MIMO, or multiple input multiple output. This video explains how MIMO works to double your channel speed by sending two or more data streams over the same channel.

As far as modern architectures go, there are few more complicated than an IoT pipeline. You’ve got to consider an ingestion layer (typically streaming) that may undergo manic load. You’ve got to think of data tagging, storage (probably across multiple engines), archival and access—both internal and external. And all of it has to scale like crazy, be as cost effective as possible, and use automation wherever it can. Oh, and your boss needs the IoT pipeline built by tomorrow. Short timelines? Tight budget? Unrealistic expectations? Unfortunately, these asks are realities for many cloud professionals. AWS knows this and is here to help.
