A Virtual Machine or a VM is a separate instance of operating system(OS) on a host physical computer in addition to host machine’s own OS, as if it were on a different computer or a guest. A host can emulate several guests, each of which can emulate different operating systems.
Host, guest and hypervisor
The computer that is running the virtual machine is called the host whereas the program that controls virtual machines is called a hypervisor. Virtual machines can be created through software known as virtualization software. Some of the popularly used virtualization softwares are Virtualbox and VMware.
What VMsoffer its users?
A VM can be easily created, modified and destroyed. We can also create and delete snapshot on a VM. A snapshot preserves the state and data of a virtual machine at a specific point in time. VM provides the flexibility to create and delete snapshots which takes a few minutes of time.
With the popularity of cloud services, cloud-based VMs use is in demand which can be accessed over an internet using a web browser. These VMs are created on a physical machine which is located at a different geographical location, which can be accessed remotely and shared by multiple users(not in parallel though) in a larger organization to make the process more agile.

Today was the absolute worst day ever And don’t try to convince me that There’s something good in every day Because, when you take a closer look, This world is a pretty evil place. Even if Some goodness does shine through once in a while Satisfaction and happiness don’t last. And it’s not true that It’s all in the mind and heart Because True happiness can be attained Only if one’s surroundings are good It’s not true that good exists I’m sure you can agree that The reality Creates My attitude It’s all beyond my control And you’ll never in a million years hear me say Today was a very good day
Now read it from bottom to top, the other way, And see what I really feel about my day 🙂
One colleague at workplace had bought a brand new phone and forgotten his Type C charger at home and was asking for people around. If he was provided with one, he constantly checked the pin end to confirm the Type C. So, this is the latest USB in and around with the mobile devices we get to see. So, lets understand the USB and its evolution.
What was used before USB?
In the pre-USB era, communication between devices was done using communications ports namely parallel ports, serial ports, gaming ports etc.
What is a USB?
The USB stands for Universal Serial Bus is a standard connector used to connect peripherals to computer. Its is the most commonly used port and as the name says its quiet Universal. Its used to connect devices such as mice, cameras, printers, scanners, external hard drives, flash drives and even can do networking and also its used to charge devices such as mobile phones.
The 1st USB version was released in 1996 with release of USB 1.0. The versions are based on the speed of data transfer were
USB 1.0 which had a speed of 1.5 Megabits/sec.
USB 1.1 with a speed of 12 Megabits/sec,
USB 2.0 with a speed of 480 Megabits/sec
USB 3.0 with a speed of 5 Gigabits/sec
USB 3.1 with a speed of 10 Gigabits/sec
USB 3.2 with a speed of 20 Gigabits/sec
USB 4.0 with a speed of 40 Gigabits/sec
In addition to different speeds of USB there were different types of USB cables, connectors and ports it uses.
A typical USB cable has two ends with two different connectors, Type A at one end and Type B or Type C at the other end of the cable. Type A connector is the host connector. This can be plugged into computers Type A USB port
USB comes in various shapes and sizes: Standard, Mini, Micro. Each of these have types which are developed with the USB standards defined above.
Type A : is the original design for the USB standard with a flat and rectangular shape. Mostly used in host devices, including desktop computers, laptops, game, media players and so on.
Type B : plugs into peripheral device such as a printer, a phone, or an external hard drive.
Type C : is a USB with a rectangular shape with rounded corners. It supports USB 3.1 with the top speed of 10Gbps and has much higher power output of up to 20V and 5A.
