Differentiatebetween:

a) Firmware Computers and Virtual Computers

b) Early binding and Late Binding

c) BNF and EBNF

a) Firmware Computers and Virtual Computers

Firmware Computers-A type of computer program that offers low-level device-specific hardware control. Once installed, the firmware is generally altered rarely and only by the manufacturer's updates. Firmware loss can often lead to the loss of function of a hardware device depending completely on the scenario.

Virtual Computers-The most common purpose of the software is to describe a program/piece of data to be changed, viewed or otherwise interacted by the user most often. A software or firmware upgrade allows a continuous change - generally a feature enhancement, performance enhancement, or error correction

b) Early binding and Late Binding

Early binding-The compiler matches the function call at compile time in early binding with the right function definition. It can be called as Compile-time Binding/Static Binding. The compiler defaults to the feature definition called during the moment of compilation. So, because of early binding, all the feature calls you've studied up to now.

Late binding-The compiler matches the function call at run-time with the right function definition in the event of late binding. It is also referred to as Run-time Binding.

The compiler defines the object type at run-time in late binding and then checks the function definition with the function call.

c) BNF and EBNF

BNF (Backus - Naur form) - It is used to officially describe a language's grammar, so there is no discrepancy or ambiguity about what is permitted and what is not. In reality, BNF is so unambiguous that there is a lot of mathematical theory around this kind of grammar, and you can effectively build a parser mechanically for a language with a BNF grammar.

EBNF (Extended Backus-Naur form) - It is used to convey a grammar that is context-free. EBNF is used to describe formally a formal language such as a language for computer programming. This is extension metasyntax notation of the fundamental Backus - Naur form (BNF).
