What is Multicloud?
Using multiple cloud services can be complicated, but there are multiple benefits
What is a virtual network
Virtual networks are vital for cloud computing, and virtual LANs can transform networks
What is hybrid cloud computing? The benefits of mixing private and public cloud services
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.
What is Wi-Fi and why is it so important?
The ubiquitous wireless technology Wi-Fi has become indispensable for home networking, public internet connectivity, supporting the internet of things and much, much more.
What is a VPN? A secure network over the internet
VPNs 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.
What is IoT? The internet of things explained
The internet of things (IoT) is a network of connected smart devices providing rich data, but it can also be a security nightmare.
What is DNS and how does it work?
The Domain Name System resolves the names of internet sites with their underlying IP addresses adding efficiency and even security in the process.
What is an IP address? And what is your IP address?
IP addresses give devices on IP networks their own identities so they can find each other.
What is IPv6, and why is adoption taking so long?
IPv6 has been in the works since 1998 to address the shortfall of IP addresses available under Ipv4, yet despite its efficiency and security advantages, adoption is still slow.
What is MPLS, and why isn't it dead yet?
Multi-protocol label switching is reliable but expensive, leading enterprises to supplement it with cheaper and more flexible SD-WAN.
What is a digital twin and why it's important to IoT
Digital twins are virtual replicas of physical devices that data scientists and IT pros can use to run simulations before actual devices are built and deployed. Digital twins can also take real-time IoT data and apply AI and data...
