Explanation:
2.There are two types of programming languages.
● Low level language
This language is the most understandable language used by computer to perform its operations. It can be further categorized into:
a) Machine language (1GL)
b) Assembly language (2GL)
● High level language
Instructions of this language closely resembles to human language or English like words. It uses mathematical notations to perform the task. The high level language is easier to learn. It requires less time to write and is easier to maintain the errors. The high level language is converted into machine language by one of the two different languages translator programs; interpreter or compiler.
High level language can be further categorized as:
a) Procedural-Oriented language (3GL)
b) Problem-Oriented language (4GL)
c) Natural language (5GL)
3. Low level languages are considered close to the machine
because of the low abstraction between the language and machine language, low-level languages are sometimes described as being "close to the hardware". A program written in a low-level language can be made to run very quickly, with a small memory footprint.
