Reading Time-approximately: 8 minutesNetwork design tools help architects map out the company infrastructure but only with the right product. Explore these eight vendors and their tools to make the right buy. By Andrew Froehlich Network architects must have the right tools on hand to create a manual network diagram. While automated tools can dynamically build maps of existing network infrastructures, architects use vector graphic tools
Reading Time-approximately: 4 minutesThe nature of the cloud market demands innovation, and custom hardware might be the next move for the major vendors in this space. Experts weigh in on the key drivers of this shift. By George Lawton Initially, public clouds were built on generic hardware to cut costs and operate at massive scale — but that’s changing. A shift toward highly scalable
Reading Time-approximately: 3 minutesIf we learned anything from 2020, it’s to expect the unexpected. Yet that doesn’t stop analysts from trying to predict what’s to come in the world of cloud computing this year. By Sara Grier At the end of every year, top IT analyst firms make cloud predictions for the 12 months ahead. Suffice it to say, no IT analysts predicted
Reading Time-approximately: 2 minutesAnnual survey of IT leaders finds network security is of prime concern as most companies continue with work-from-home policies.

But as enterprises continue working remotely with very few making a complete return to the office, securing the remote workforce is
Reading Time-approximately: 7 minutesRAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor. Posted by: Margaret Rouse WhatIs.com Contributor(s): Kevin Ferguson, Stacey Peterson and Rodney Brown RAM is the main memory in a computer. It is much faster to read from and write to than other
Reading Time-approximately: 3 minutesEven though vendors refer to flash memory and conventional RAM — the main memory of your PC or server — as solid-state memory, these two memory types are significantly different. By Erin Sullivan and Rodney Brown When discussing flash memory vs. RAM, you might be inclined to lump them together based on their similarities. While both technologies are made up of solid-state
Reading Time-approximately: 4 minutesNOR flash memory is one of two types of non-volatile storage technologies. NAND is the other. Non-volatile memory doesn’t require power to retain data. Posted by: Margaret Rouse WhatIs.com Contributor(s): Ben Lutkevich; Brien Posey; Rodney Brown NOR and NAND use different logic gates — the fundamental building block of digital circuits — in each memory cell to map data. Both types of flash memory were invented by Toshiba,
Reading Time-approximately: 3 minutesHot sites are a viable disaster recovery strategy, but high costs and changing DR risks have made alternatives like disaster recovery as a service a more appealing option. By Alan R. Earls Not too long ago, the gold standard for IT preparedness was having a dedicated facility for hot site disaster recovery. Now, at a time when bullet-proof, interruption-free IT
Reading Time-approximately: 4 minutesPredictably, some 2019 forecasts of what disaster recovery might look like in 2020 didn’t quite hit the mark. However, funding and cybersecurity were evergreen concerns. By Alan R. Earls Disaster recovery strategies have had to change drastically from expectations in 2019. The COVID-19 pandemic presented many disaster recovery challenges for teams in 2020, as remote work became the norm. At
Reading Time-approximately: 4 minutesAs a replacement for the SCSI storage protocol, NVMe can provide more responsive storage and lower latency. But transitioning to NVMe in the data center requires thorough planning. By George Crump Nonvolatile memory express is a storage protocol designed specifically for memory-based storage, enabling technologies like flash to reach their full potential. Since NVMe technology is a change to infrastructure,
What is COVID-19?
On 31 December 2019, the World Health Organization (WHO) reported a cluster of pneumonia cases in Wuhan City, China. ‘Severe Acute Respiratory Syndrome Coronavirus 2’ (SARS-CoV-2) was confirmed as the causative agent of what we now know as ‘Coronavirus Disease 2019’ (COVID-19). Since then, the virus has spread to more than 100 countries, including South Africa.
