Online applications (also known as SaaS or web apps or webware) are getting more popular, particularly since broadband Internet access has become more common and readily available to more users. With online applications and services, you do not need to download and install them into your computer for using them—you just need to open up a browser and access them online.
Besides, you don't have to worry about different operating systems as these applications and services are cross-platform, running in your browser as a client. Neither do you need to keep updating your software versions, as you will get any new software updates and bug fixes automatically whenever you access them.
