please answer the following question:-
1)How is 1GLs different from 2GLs?
2)Why were 4GLs developed ?
Answers
Answer:
1GLS are machine languages. Machine languages are the only languages that the CPU understands and are unreadable by the majority of programmers. Each type of computer has its own machine language. 2GLS are assembly languages.
2.What is the importance of 4GL? The idea of 4GL is to make programming as simple as possible by the mean of programming in natural human language [2], [3]. 4GLs aim to make programming easier, more efficient and more effective for users with less programming skills
Explanation:
Answer:
1. Difference :
i) 1GL is essentially a machine language, 2GL refers to assembly language.
ii) 1GL uses binary digits (i.e. 0,1), 2GL uses symbols instead of 0,1.
2. 4GLs were developed to reduce programming time, efforts and cost. It has a very high speed of execution.
