What is the main difference between...?

Question

...a functional programming language, and an imperative programming language?

Answer 1

Functional programming is a programming paradigm that conceives computation as the evaluation of mathematical functions and avoids state and mutable data. Functional programming emphasizes the definition of functions, in contrast to imperative programming, which emphasizes changes in state and the execution of sequential commands.

In computer science, imperative programming, as opposed to declarative programming, is a programming paradigm that describes computation in terms of a program state and statements that change the program state. In much the same way as the imperative mood in natural languages expresses commands to take action, imperative programs are a sequence of commands for the computer to perform.

When distributed systems first appeared, they were programmed in traditional sequential languages, usually with the addition of a few library procedures for sending and receiving messages. As distributed applications became more commonplace and more sophisticated, this ad hoc approach became less satisfactory. Researchers all over the world began designing new programming languages specifically for implementing distributed applications. These languages and their history, their underlying principles, their design, and their use are the subject of this paper. We begin by giving our view of what a distributed system is, illustrating with examples to avoid confusion on this important and controversial point. We then describe the three main characteristics that distinguish distributed programming languages from traditional sequential languages, namely, how they deal with parallelism, communication, and partial failures.

In general, a distributed computing system is one in which more than one computer collaborates in the implementation of a calculation.

Paganism is a great type of religions. it rather is stressful to define yet oftentimes is seen as being any faith that the two is non-Abrahamic (no longer Jewish, Christian, Muslim and so on), is polytheistic or is in line with pre-Christian eu traditions. there are various pagan religions alongside with Wicca, Druidry, Thelema and various reconstructionist faiths between many others. some may be extremely diverse than others on an identical time as some proportion many similarities. Wicca is a particular pagan faith that specializes in a God/Goddess duality, celebrates 8 image voltaic holiday journeys, quite a few lunar activities and is oftentimes linked with witchcraft. Wicca isn't a "branch" of paganism, in view that paganism isn't a faith. Wicca is a faith which would be defined as pagan. All Wiccans are pagans. no longer all pagans are Wiccans. Paganism has an considerable variety of ideals, so there is no thank you to describe how "paganism" is diverse than Wicca, relatively considering the undeniable fact that Wicca is pagan. No disrespect taken. it rather is often stunning whilst people opt to truly comprehend greater approximately my faith-crew. -Scarlet
