Virtual and self-healing hardware

“

- In this lesson, we're going to talk about virtual hardware and self-healing hardware. Let's start with virtual hardware. CompTIA describes virtual hardware as software that emulates physical hardware. So this allows for multiple operating systems and applications to share the same physical hardware resources. We often call these virtual machine managers or hypervisors. This enables more efficient use of resources, improved scalability, and greater flexibility in managing our IT infrastructure. Some examples of virtual hardware would be virtual CPUs, software-based processors that emulate physical CPUs. Virtual memory, emulated memory resources that provide virtual machines with their own address space. And virtual NICs, network interface cards. These are software-based network interfaces that allow virtual machines to communicate over a network. For example, at Amazon Web Services, if you spin up, let's say a Windows server, it's going to get a virtual NIC and a logical MAC address,…
