Power over Ethernet technology has evolved to be a key part of wireless LAN architectures, smart buildings and enterprise networks
Virtual networks power cloud computing, VPNs and virtual LANs
How to architect a hybrid cloud that combines on-premises and public cloud infrastructures. Definitions of hybrid cloud vary, but here’s what it means to Amazon, Microsoft and Google.
The ubiquitous wireless technology Wi-Fi has become indispensable for home networking, public internet connectivity, supporting the internet of things and much, much more.
Virtual private networks can create secure remote-access and site-to-site connections inexpensively, are a stepping stone to software-defined WANs, and are proving useful in IoT.
IP addresses are one of the fundamental building blocks of the internet, but could pose a potential security liability, if an attacker were to get ahold of yours.
Hyperconverged infrastructure (HCI) combines compute, storage and networking in a single system. Enterprises can choose an appliance from a single vendor, or hardware-agnostic hyperconvergence software.
The maximum transmission unit (MTU) for a protocol sets the top limit on how big its packets can be. However, the network devices they pass through, encapsulation, and other factors can complicate things.
Improvements in network-attached storage density and performance target unstructured data workloads. Here's how a NAS server works, how it is different from a SAN, and what IT buyers want in file-level storage.
The IEEE 802.1X standard allows network switches and access points to hand off device authentication to a specialized server so it can be managed and updated centrally.
