In the network terms we often hear about The solutions and services. I want to know what is the difference between them? and How we categorized network related functions under these two titles? Thank you.
Solutions could be a Network specifically designed for your organization or company. A complete network (plug and play) that supports your needs with up-to-date standards, features and securities. Solutions could also be smaller parts of that, for instance, if you only need VoIP for your company, then you can buy a plug and play VoIP solution.
A network service is an application running at the network application layer and above, that provides data storage, manipulation, presentation, communication or other capability which is often implemented using a client-server or peer-to-peer architecture based on application layer network protocols.
You could say, that a network solution is the infrastructure that you implement your network service on.
