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,
Reading Time-approximately: 8 minutesNVMe (non-volatile memory express) is a host controller interface and storage protocol created to accelerate the transfer speed of data between enterprise and client systems and solid-state drives (SSDs) over a computer’s high-speed Peripheral Component Interconnect Express (PCIe) bus. Posted by: Margaret Rouse WhatIs.com Contributor(s): Rich Castagna; Carol Sliwa As solid-state technology became the preferred medium in the storage market, it quickly became clear that existing interfaces
Reading Time-approximately: 5 minutesThe non-volatile memory express protocol is tailor-made to make SSDs fast. Get up to speed on NVMe performance and how it compares to the SATA and SAS interfaces. By Robert Sheldon The NVMe protocol is quickly becoming the industry standard for supporting solid-state drives and other non-volatile memory subsystems. NVMe SSD speeds are substantially better than traditional storage protocols, such
Reading Time-approximately: 8 minutesAlthough storage virtualization is a term that is used extensively throughout the storageindustry, it can be applied to a wide range of technologies and underlying capabilities. Inreality, most storage devices can technically claim to be virtualized in one form or another. Tekmart Support Team Therefore, we must start by defining the concept of storage virtualization as used in this tutorial.
Reading Time-approximately: 4 minutesNetwork visibility is an awareness of the components within and the data moving through an enterprise computer network. The term is often used to refer to the various tools enterprises use to increase awareness of their data and other network contents. Posted by: Margaret Rouse WhatIs.com Contributor(s): Ben Lutkevich Taking a proactive approach to network visibility allows enterprises to better monitor network
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.
