The UK Department for Science, Innovation and Technology (DSIT) has revealed what its future Cybersecurity Governance Code of Practice will look like and the five principals it will include. While the document is undergoing final review, Jack Harrigan, head of cyber governance & accountability at DSIT, shared a glimpse of what final version during the […]
What is a printed circuit board (PCB)? A printed circuit board (PCB) is a structure for assembling electronic components and their connections into a unified circuit that allows electrical current to pass between components. The PCB baseboard is typically made of a rigid nonconductive material, although it can also be built on a flexible base […]
What is a context switch? A context switch is an operation that a computer’s central processing unit (CPU) carries out when alternating between processes or threads while ensuring that the processes do not conflict. Effective context switching makes it possible to support a multitasking environment. Each time the CPU makes a switch, the system temporarily […]

What is a hypervisor? A hypervisor is software that facilitates running multiple virtual machines (VMs) with their own operating systems on a single computer host’s hardware. The host machine and its physical hardware resources independently operate one or more VMs as guest operating systems. Multiple guest VMs share the system’s physical compute resources, including processor […]
What is on-demand computing (ODC)? On-demand computing (ODC) is a delivery model in which computing resources are made available to the user as needed. The resources might be maintained within the user’s enterprise or made available by a cloud service provider. The on-demand business computing model was developed to overcome the challenge of enterprises meeting […]
