Hey there!
The most commonly used hardware interface for attaching peripherals to a microcomputer is the universal series bus, or USB, port. Many computers have at least 2 to 4 USB ports that allow for multiple devices to be plugged in at once. In terms of wired devices as opposed to wireless, this is the main way that a mouse, a keyboard, a smartphone (for charging and syncing information), and many other devices are connected to computers.
Hope this helped you out! :-)
If you have only 1 method that is not overloaded, then you will not be able to call it with inappropriate parameter types, that is, if the initial type of the parameter is int, then it will not be able to get the double, float, and other values, because of this an error will occur.
For this, method overloading is created.
Method overloading is when you create methods with the same name, but only the content and parameters of the methods are/can-be completely different.
Most of the web applications are written with SPA frameworks such as Angular, React, Vue.js, etc. The problem with these SPAs is that the single page is loaded in the browser once and then the framework will take care of all the routing among pages and gives the impression to the user that it is a multi-page application. When you refresh your page in the browser that single page called index.html is reloaded and you will lose the entire state of the application.
