Answer:
A. True
Step-by-step explanation:
A web application or web app can be defined as a software application which typically runs on a web server in order to provide specific services to the end users.
Generally, all web applications can only be used or accessed by the end users through a web browser and an active internet connection. Thus, all websites are assigned a uniform resource locator (URL), which identifies the logical address of the web page on the internet.
Hence, you must be online to use web apps.
Some examples of web applications are e-commerce websites (Amazon, eBay, Konga, Jumia etc), online banking, web-mail (G-mail, AOL, Yahoo etc).
Additionally, all web apps are designed and developed to use a client-server model through cloud computing.
