Reading Time-approximately: 5 minutesA carbon offset is a credit that a person or organization can buy to decrease its carbon footprint. When the number of carbon offset credits obtained is equal to an individual or organization’s carbon footprint, that person or organization is carbon-neutral. By Ben Lutkevich Revenue generated from the purchase of carbon offsets is often — but not always — invested in
Reading Time-approximately: 3 minutesIT asset disposition (ITAD) is an industry term and practice built around reusing, recycling, repurposing, repairing or disposing of unwanted IT equipment in a safe and environmentally responsible way. By Alexander S. Gillis An IT organization can practice IT asset disposition itself or have a specialized vendor handle it. Instead of ending up as electronic waste, or e-waste, in a landfill,
Reading Time-approximately: 7 minutesThis guide to network management explains the challenges of enterprise network monitoring and maintenance, best practices and next-generation automation using AI and ML. By Chuck Moozakis and Sandra Gittlen Network management is a cornerstone of IT that helps ensure enterprises run efficiently and effectively end to end. Technologies such as AI and machine learning are beginning to automate many of the functions of network administration and
Reading Time-approximately: 4 minutesA computer network is a system of computers and computing devices that are connected via communication links. By Ben Lutkevich and Kate Gerwig These links allow the computers and other devices to send information over the network. Network protocols define how information is sent and received. Networks can be defined by their geographic location, the protocols they use, the physical arrangement
Reading Time-approximately: 3 minutesNACK, or NAK, an abbreviation for negative acknowledgment or not acknowledged, is a signal used by computers or other devices to indicate that data transmitted over a network was received with errors or was otherwise unreadable. By Katie Terrell Hanna and Peter Loshin NACK is sometimes conflated with automatic repeat request (ARQ) or with the rejected (REJ) message, though the

By Rahul Awati SPARC is based on reduced instruction set computing (RISC). SPARC has become a widely used architecture for hardware used with UNIX-based operating systems, including Sun’s own Solaris systems. Sun made SPARC an open architecture that is available for licensing to microprocessor manufacturers. Sun was acquired by Oracle Corporation in January

Learn about other tasks and best practices. By Damon Garn Network nodes require an IP address configuration that usually comprises the IP address, subnet mask, default gateway IP for the router, name servers and other values. Administrators can manually set
Reading Time-approximately: 4 minutesA host bus adapter (HBA) is a circuit board or integrated circuit adapter that connects a host system, such as a server, to a storage or network device. By Robert Sheldon and Carol Sliwa An HBA also provides input/output (I/O) processing to reduce the load on the host’s microprocessor when storing and retrieving data, helping to improve the host’s overall performance. An HBA and its associated disk subsystems are sometimes
Reading Time-approximately: 4 minutesSome of the different types of network switches include managed, modular, unmanaged and stackable. Find out how different network switches dovetail and differ. By Andrew Froehlich These days, a switch is a switch, right? Well, not necessarily. While all network switches move data from point A to point B, many enterprise-grade switches have significant hardware and software differences that factor
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).
