Git and GitHub, are they same or different? Discuss with facts

Git is a distributed version control tool that can manage a development project's source code history, while GitHub is a cloud based platform built around the Git tool. Git is a tool a developer installs locally on their computer, while GitHub is an online service that stores code pushed to it from computers running the Git tool. The key difference between Git and GitHub is that Git is an open-source tool developers install locally to manage source code, while GitHub is an online service to which developers who use Git can connect and upload or download resources.

Compare and contrast the Git commands, commit and push

Git is a distributed version control system, the difference is that commit will commit changes to your local repository, whereas push will push changes up to a remote repo. git commit record your changes to the local repository. git push update the remote repository with your local changes.

Discuss the use of staging area and Git directory 

Basic is you modify files in your working directory. You stage the files, adding snapshots of them to your staging area. You do a commit, which takes the files as they are in the staging area and stores that snapshot permanently to your Git directory.

Explain the collaboration workflow of Git, with example 

In terms of Git process, collaboration is often about branching workflows.Thinking ahead on. This will inhibit your ability to release what is ready. Topic Branches. Another Git workflow example is known as "opic branches".

 Discuss the benefits of CDNs 

CDNs accelerate website performance and provide a numerous benefits for users and also for the network infrastructure. The internet is a collection of numerous networks or datacenters.CDNs provide web content services by duplicating content from other servers and directing it to users from the nearest data center.

How CDNs differ from web hosting servers

Differences Between CDNs and Web Hosting. Web Hosting is used to host your website on a server and let users access it over the internet. Web Hosting normally refers to one server. A content delivery network refers to a global network of edge servers which distributes your content from a multi-host environment.

Discuss the requirements for virtualization 

The three elements to consider when selecting virtualization hardware include the CPU, memory, and network I/O capacity.

What is the hypervisor and what is the role of it

A hypervisor or virtual machine monitor is computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.

 How does the emulation is different from VM

Virtual machines make use of CPU self-virtualization, to whatever extent it exists, to provide a virtualized interface to the real hardware.Emulators emulate hardware without relying on the CPU being able to run code directly and redirect some operations to a hypervisor controlling the virtual container.
