Lisa Bock discusses how, when conducting packet analysis, you may have to deal with a variety of networks, such as a campus area or local area network, as well as working with different types of media.
- [Instructor] Effective packet analysis begins…by understanding the network architecture…and the ways the different media…and devices influence the network traffic in order…to determine where to tap in to identify trouble spots.…Today's network environments can include mobile phones,…cloud computing, virtualization,…social media, and the internet of things.…A local area network is a private network.…
It's in a localized area that an organization…or individual owns, controls, and manages.…A LAN is generally within a restricted…or geographic area such as a corporate office,…manufacturing plant, or healthcare facility,…that share resource, communicate,…and exchange data on a common channel.…Within the LAN, the network might have a data center,…which is a large group of servers that provide storage,…processing, and distribution of critical…company data for network clients.…
The data center is the heart of any enterprise network,…and is located in a central location,…generally in a secure computer or server room.…
