In day to day basis we use or interact with different kind of computing like desktop computing where you have dedicated hardware resources (RAM, hard disk, network interface card etc) and also an operating system like WindowXp, ubuntu. If your requirement increases which can't be fulfilled with current configuration of your laptop, you may have to buy another machine (hardware as well as operating system).
In case of cloud computing, you don't need to purchase hardware every time and also not to do IT related work networking, OS installation etc. As user you have to just use machine which may not be physically located nearby but using the internet you would be able to do all the things which you can do by using the desktop machine. One more advantage here is based on your requirement or need, network grows and shrink. Based on the usage of cloud resources, service provider will charge you.
In telecom domain, you might have heard about cloud RAN, virtual EPC etc. All those things are related to implementation of telecom nodes or functionalities by using cloud computing.
