What is an IP address? And what is your IP address?

What is IPv6, and why is adoption taking so long?

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?

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

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...

What is hyperconvergence?

What is hyperconvergence?

Hyperconvergence aims to simplify data center operations by combining compute, storage and networking in a single system. Enterprises can choose an integrated HCI appliance from a single vendor, or hardware-agnostic hyperconvergence...

MTU size issues, fragmentation, and jumbo frames

MTU size issues, fragmentation, and jumbo frames

The maximum transmission unit (MTU) is the largest number of bytes an individual datagram can have without either being fragmented into smaller datagrams or being dropped along the path between its source and its destination. For...

What is NAS (network-attached storage) and how does it work?

What is NAS (network-attached storage) and how does it work?

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.

What is a WAN? Wide-area network definition and examples

What is a WAN? Wide-area network definition and examples

WANs connect smaller networks across long distances, and their architecture, protocols and technologies have evolved to their latest incarnation, SD-WAN.

What are data centers? How they work and how they are changing in size and scope

What are data centers? How they work and how they are changing in size and scope

The future of data centers will rely on cloud, hyperconverged infrastructure and more powerful devices.

What is DNS and how does it work?

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.
