Hypervisor vs VM
A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing. aka a referee for VMs
VM
In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and …
Advantages of VMs over Computers
One major advantage is their flexibility and versatility. VMs can be easily created, cloned, and moved between different physical hosts, which makes them ideal for testing and development environments. Additionally, VMs can be configured to run different operating systems or software configurations, which allows for greater compatibility and flexibility. Another advantage of VMs is their security. VMs can be isolated from the host operating system and other VMs, which makes them less vulnerable to security threats. Finally, VMs can provide better resource utilization and efficiency, as multiple VMs can run on a single physical host, reducing the need for additional hardware. Overall, VMs offer many benefits over traditional computers and are becoming increasingly popular in a variety of industries.
Symetric vs Non Symmetric Keys
Symmetric encryption involves using a single key to encrypt and decrypt data, while asymmetric encryption uses two keys - one public and one private - to encrypt and decrypt data.
what is hashing
Hashing is the process of transforming any given key or a string of characters into another value. This is usually represented by a shorter, fixed-length value or key that represents and makes it easier to find or employ the original string. The most popular use for hashing is the implementation of hash tables.
