PROGRAM – 1
A programming language defines a set of instructions that are compiled together to Performa specific
tasks by the CPU (central Processing Unit). The programming language mainly refers to high – level
languages such as C, C++, Pascal, Ada, COBOL , etc .
Each Programming languages contains a unique set of keywords and syntax, which are used to create a
set of instructions. Thousands of programming languages have been developed till now, but each
languages has its specific purpose . These languages vary in t the level of abstraction they provide from
the hardware . Some programming languages provide less or no abstracton while some provide higher
abstraction . Based on the levels of abstraction, they can be classified into two categories:
Low – level language
High – level language
LOW-LEVEL LANGUAGES
The low level languages is a programming languages that provides no abstraction from the
hardware, and it is represent in 0 and 1 forms , which are the machine instructions . The
languages that come under this category are the Machine level languages and Assembly
languages.
HIGH – LEVEL LANGUAGES
The high- level language is a programming language that allows a programmer to write the programs
which are independent of a particular type of computer . The high-level languages are considered as
high- level languages because they are closer to human languages than machine – level languages .
When writing a program in a high – level language , then the whole attention needs to be paid to the
logic of the problem .
A compiler is required to translate a high – level language into a low – level language .
