What is IoT? The internet of things explained

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.

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

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?

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.

High-performance computing as a service: What you need to know

High-performance computing as a service: What you need to know

HPC services can be a way to meet expanding supercomputing needs, but depending on the use case, they’re not necessarily better than on-premises supercomputers.

What is 5G? Fast wireless technology for enterprises and phones

What is 5G? Fast wireless technology for enterprises and phones

5G networks will boost wireless throughput by a factor of 10 and may replace wired broadband. But when will they be available, and why are 5G and IoT so linked together?
