Answers
Answer:
Of which Subject is it???
Answer:
1 a) A language is a system of communication which consists of a set of sounds and written symbols which are used by the people of a particular country or region for talking or writing.
b) A program (noun) is executable software that runs on a computer. It is similar to a script, but is often much larger in size and does not require a scripting engine to run. Instead, a program consists of compiled code that can run directly from the computer's operating system.
c) A programming language is a formal language, which comprises a set of instructions that produce various kinds of output. Programming languages are used in computer programming to implement algorithms. Most programming languages consist of instructions for computers.
2. Augusta Ada King, Countess of Lovelace (née Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine.
3. He reportedly came up with the word in 1953 to mark the difference between computer programs and the computers (or "hardware") that use the programs. John W. Tukey, a chemist and statistician, is credited with the first printed use of the term when he wrote a scientific article in 1958.
4. Assembly language programs are translated into machine language by a program called an assembler. Every CPU has its own unique machine language. Programs must be rewritten or recompiled, therefore, to run on different types of computers.
5. Interpreter is a program that executes instructions written in a high-level language. There are two ways to run programs written in a high-level language. The most common is to compile the program; the other method is to pass the program through an interpreter.
