NOTE
HIGH LEVEL PROGRAMMING LANGUAGE
High level languages are human understandable languages. They allow programmers to write programs that are not dependent on the design of the CPU. High level languages are human languages and are used to solve problems.
The advantage of high-level languages over low level languages is that they are easier to read, easier to write and easier to use. However, programs written in high level languages must be translated into a language the computer understands. i.e. machine language by a translator. Examples of high-level languages are:
DIFFERENCE BETWEEN HIGH LEVEL AND LOW LEVEL LANGUAGES
|
High level language |
Low level language |
|
1. It requires the use of translator (compiler or interpreter) for their translation into the machine code |
It requires an assembler for directly translating the instructions of the machine language |
|
2. They are human friendly. They are very easy to understand and can be learnt by any programmer |
They are machine friendly. They are very difficult to understand and learnt by any human |
|
3. They are machine independent |
They are machine dependent |
|
4. It is very easy to debug these languages |
It is not easy to debug these languages
|
EVALUATION: 1. Explain high-level programming language
