Study Notes
History of Computers
- Computers are used in many areas of life, including education, business, and personal use.
- Computers are defined as devices capable of storing, processing data, and producing output.
- The Analytical Engine, invented by Charles Babbage in the 19th century, was designed to perform arithmetic operations.
- The Analytical Engine used punch cards for data input.
- Ada Lovelace, an English mathematician, collaborated with Babbage and wrote the first computer program for the Analytical Engine, predicting the potential of computers to process different types of data.
- The Electronic Numerical Integrator and Computer (ENIAC) was built at the University of Pennsylvania between 1943 and 1945 by John Mauchly and J. Presper Eckert.
- ENIAC was designed to calculate artillery firing tables for the US Army's Ballistic Research Laboratory.

- The Atanasoff-Berry Computer was designed to solve systems of simultaneous linear equations.
- IBM revolutionized the computer world with the introduction of mainframe computers, used by large organizations for business operations.
- IBM's personal computer (PC) made computers accessible for home and office use.
- Apple's Macintosh computer introduced an icon-driven interface.
Understanding Computers
- Computers perform four essential tasks: input, storage, processing, and output.
- Data and information are represented in computers using binary code (1s and 0s).
Hardware vs. Software
- Hardware refers to the physical components of a computer system.
- Software is the collection of instructions that computers use to process data.
Fundamental Components
- CPU (Central Processing Unit) is the brain of the computer responsible for calculations.
Types of Software
- System Software manages the basic operations of a computer.
- Utility Programs perform tasks like virus scanning, data backup, and file compression.
- Software Development Tools are used by programmers to build applications.
- Application Software is designed for specific user tasks.
Programming
- Programming is the process of creating instructions for a computer to perform a task.
- Early programs were written using machine code (sequences of 0s and 1s).
- Assembly language was introduced to make programming easier for people.
- High-level programming languages like Fortran and COBOL made programming more user-friendly.
Important Programming Languages
- C is a flexible language widely used for system-level programming.
- Python is a beginner-friendly language known for its readability.
- Java is a portable language, making it suitable for large-scale systems.
Real-world Applications of Programming
- Websites & Web Apps
- Mobile Apps
- Games
- Automation
- Data Analysis & Artificial Intelligence
- Embedded Systems
System Development Life Cycle (SDLC)
- The SDLC is a systematic process for developing software applications.
- Planning Phase: defines the goals and scope of the project.
- Analysis Phase: analyzes the project needs and requirements.
- Design Phase: plans the software structure and user interface.
- Development Phase: programmers write the code.
- Testing Phase: tests the software for functionality and bug fixes.
- Deployment Phase: makes the software available for users.
- Maintenance Phase: ensures the software continues to function correctly.
Steps in Program Development
- Analyze Programming Problems: understand the problem and its requirements.
- Design Algorithms: create step-by-step procedures to solve the problem.
