Key Differences
A function usually denotes a distinct purpose or duty assigned to someone or something, as in mathematics or in job roles. On the other hand, an operation might refer to the process of operating or the state of being operational, commonly used in the context of business or surgery.
In mathematics, a function represents a relationship between a set of inputs and a set of potential outputs, each input being associated with exactly one output. Whereas, an operation in mathematics refers to a calculation from zero or more input values (called operands) to an output value.
In programming, a function is a block of code designed to perform a particular task; it can be invoked as needed within a program. On the other hand, operation can describe any type of action that changes the state of the system, such as reading data, modifying files, etc.
In the context of business, a function might describe a specific department or role, like marketing or sales. Conversely, operation refers to the ongoing activities that a business undertakes to produce goods or services and ensure they reach the market.
For everyday electronics, a function can mean a specific setting or mode, like on a remote control. In contrast, operation refers to the general use of the device, encompassing all its functions and maintenance.
