Instructor John Harmon explains subnetting using binary numbers and decimal conversions.
Instructor John Harmon continues his explanation of subnetting by showing how subnet masks can be used to sub-divide networks.
There are several Wireless LAN Standards, including b, g, and n, which exist in the 2.4 GHz band. These standards need around 20 MHz of radio frequency in order to transmit their signals. In this video, Ben Miller discusses how to pick access points and channels for optimal performance.
Answer? When it is flagged as a retransmission in Wireshark!
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.
Now that we have looked at the similarities and differences between the first two steps of the military decision-making process (MDMP) and the project management processes from the planning process group that align with them, it’s time to take a look at the third ste...
Are you at a crossroads professionally or looking to start training for a new job? If so, you might want to consider pursuing network administration as a career. Network administrators are responsible for maintaining computer hardware and software systems that make up a computer network, including maintaining and monitoring active data networks, converged infrastructure networks, and related network equipment.
Global Knowledge Product Manager Tori Easterly discusses the benefits of our Understanding Networking Fundamentals course.
Multiplexing is the technology that is able to combine multiple communication signals together in order for them to traverse an otherwise single signal communication medium simultaneously. Multiplexing can be applied to both analog and digital signals. A benefit of using multiplexing, or muxing, is reducing the physical hardware cost for expensive dedicated network communication segments, such as copper or fiber cables.
For a project manager (PM) who has served as a military officer on a battalion or higher staff, the parallels between the military decision-making process (MDMP), the orders production process, and project management doctrine prescribed by the Project Management Institute (PMI) are difficult to ignore. Both the MDMP and the processes outlined in A Guide to the Project Management Body of Knowledge—Fifth Edition (PMBOK® Guide) are iterative in nature, allow for the introduction of changes to the original plan, assign tasks and responsibilities, and involve the concept of managing the scope of the operation or project.
