Study Notes
Programming Languages
- A computer program is a set of instructions that a computer can follow to perform a specific task.
- Programmers write, develop, and debug computer programs.
- Programming is the art and science of creating computer programs.
- Programming languages are tools used by programmers to communicate with computers. They allow instructions to be easily understood by humans and translated into machine-readable codes.
Machine Language
- Computers understand machine language, which is a binary language using only 0s and 1s.
- The binary system is based on two digits: 0 and 1, representing "on" and "off."
- Humans use the decimal numeral system, which is based on ten digits (0-9).
Software Development Life Cycle (SDLC)
- The Software Development Life Cycle (SDLC) is a process for creating and maintaining software systems.
- SDLC involves a detailed plan for developing software.
Stages in Software Development
-
Requirements:
- The initial stage focuses on gathering requirements for the software product.
- Requirements define the actions of both the user and the computer.
- Methods for gathering requirements include documentation, procedures, rules, Standard Operating Procedures (SOPs), interviews, observations, and surveys.
- No coding occurs during the requirements stage.
-
Planning/Design:
- Involves planning the implementation and initial architecture of the program.
- This stage outlines the platforms, technologies, and program structure.
- Instructions are usually written using pseudocode or algorithms for easy understanding by programmers.
-
Design:
- Follows the requirements and planning stage.
- Focuses on creating a detailed blueprint for the software.
-
Implementation:
- The stage where the planned design is put into action.
- Actual coding and development happen during implementation.
-
Testing and Debugging:
- Thoroughly testing the program to identify and fix errors.
- Debugging involves finding and resolving defects in the software.
-
Deployment:
- Deploying the software to the intended environment.
- This includes creating program documentation and user manuals.
-
Maintenance:
- The ongoing process of maintaining and updating the software.
- Includes fixing bugs, adding enhancements, and ensuring continued functionality.
-
Support:
- Providing ongoing support for the deployed software.
- May involve troubleshooting issues, answering user questions, and providing updates.
