The document discusses computer clusters, which are groups of connected computers seen as a single system, managed by a cluster manager, and categorized into types such as high availability and load balancing clusters. It also outlines hypervisors, software that allows multiple virtual machines to share hardware resources, detailing their types (Type 1 and Type 2) and providing examples for each. References for further reading on the topics of computer clusters and hypervisors are also included.

3. Computer clusters (definition)
 Is a set of tightly connected computers that work together so that, they can be
viewed as a single system.
 One of those nodes will act as a cluster manager and the reset act as workers.
 Clients/users communicate/See only with the manager

9. Hypervisors (definition)
 A hypervisor, is a Software that allows you to share the capabilities/resources of
certain HW in-between different VM and/or the host machine.
 Hypervisors deduct HW resources for each VM (cores, RAM, storage and …)
 So with hypervisor, you can run several operating systems simultaneously on the
same machine.
 Dual boot is not a type of hypervisors
