Programming Languages Overview

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.
