Another language is assembly language, which was used more than mechanical language. Assembly language is easier to compose and understand. This language was used more by programmers because it was more users friendly and made up of easily recognizable codes that translate to programming language in a one-to-one ratio. One machine language is translated for each assembly language code used. An assembler is needed to translate into machine code. The assembler was the program that translates programming language into machine code.
The third basic language is the high-level language. This language consists of mainly English words and phrases. Between the three languages, high-level language is the easiest language to learn and to use. Also the high-level language is simple to read and modify. High-Level language does not have the one-to-one ration with machine language but can translate into instructions in machine language. The disadvantages of using high-level language are less powerful and produce less capable programs.
There are so many programming languages that exist because there are different people who become comfortable with either one language or another. Different program languages are created for different types of software programs. Programmers will most commonly become comfortable with one language and stick with that preferable language.
There exists a relationship between the computer program and how a computer processes and stores data. The computer program carries a highly important job for the computer, which processes commands and gives a set of rules for the computer to follow. The computer will process the data and output information and store data. A computer program is a necessary tool for any computer to function.
The program development cycle consists of four steps and is used to confirm that the program is developed properly. The first step in the cycle is to analyze the problem. The second step is to design a program in order to solve the problem. The third step is to code the program. The fourth and final step is to test the program and make sure that it is working fine. The cycle is referred to a cycle because the steps can be returned to whenever needed.
The importance of using a structured, modular approach when creating a program is to make it error free. This way the programmer can make sure that everything is working as programmed. Everything should meet the requirements and all the programming should be designed correctly. Besides the programmer, the end-users should also be involved in the stages of the program development cycle. By knowing what is needed and what is wanted by the end-user, which makes it clear and offer the necessary items to make everyone content.
