Слайд 2Assembly language
An assembly language is a low-level programming language for

a computer, or other programmable device.
Assembly language is converted

into executable machine code by a utility program referred to as an assembler.

Слайд 3Machine code
Machine code, also known as machine language, is the

elemental language of computers. It is read by the computer's

central processing unit (CPU), is composed of digital binary numbers and looks like a very long sequence of zeros and ones.

e.g. 10001000 01010111 11000101 11110001 10100001 00010110

Each instruction performs a very specific task, such as loading a value into a register, or adding two binary numbers together.

Слайд 5 declarative programming
declarative programming is a programming paradigm—a style of

building the structure and elements of computer programs—that expresses the

logic of a computation without describing its control flow.

Слайд 6Imperative language
In computer science, imperative programming is a programming paradigm

that uses statements that change a program's state. In much

the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing how a program operates.
