System software is a computer program that runs a computer's hardware as well as application programs and interfaces between actual hardware and applications. Example: A university's registration system would have a "student registers for classes" feature.
Although responsibilities can be allocated arbitrarily to any modules, software architecture constrains this allocation when other quality attributes are important. It differs from hardware reliability in that it reflects the design …
Identification of the needed functionality follows.Functions don't fit well into the context of a user story and are mostly transparent to a user. The steering wheel is a feature, as is the gear stick. Functions are the “product’s answer to the set of user tasks”; features are the “user tools” inherent in the product used to perform the functions . Legacy software cannot keep tuning with the latest technology available in the market. 10 Essential Accounting Software Features. Sometimes it gets as big as a subsystem, something like "the ability to send SMS via web application". At first glance, it might appear that all accounting software is pretty much the same, offering accounts receivable, accounts payable, general ledger, billing and a variety of other standard components. For example, initially Unix was developed in assembly language.

Functionality is the ability of the system to do the work for which it was intended. An application platform should support an application in every style, from single-user applications on a device to thousand-user applications in the cloud.
