Cloud computing enables development teams to get applications into production faster. IT Service Management (ITSM) leaders must adopt new strategies and change existing processes or risk becoming a barrier to success. Cloud computing requires DevOps-the blending of development and operations with the goal of accelerating time-to-market and reducing time-to-value. The good news is that ITIL® is uniquely positioned to accelerate DevOps, but it requires changes to existing ITSM processes.
For us wireless folks that aren’t stellar routing and switching guys, one of the most daunting network tasks is integrating our WLAN infrastructure with the existing wired infrastructure and its services. Understanding wired design topics is pretty fundamental to installing or managing any network, so it really should be on our priority list to spruce up those skills. To give you a nudge on your journey, let’s talk about DHCP for wireless clients.
While Apple has created many fine things, they were yet to be created themselves when Xerox PARC scientists created Media Access Control addresses. These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below:
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.
Traditionally, ITIL and TOGAF professionals have been part of different teams within an organization. Due to the ongoing alignment of business and IT, these professionals now often find themselves on the same team. Because of this crossover, there is a growing trend towards organization of work based on multiple best practice models.
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.
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.
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.
