Introduction:
The word "computer" is derived from the Latin word "computare," which means "to calculate," "to count," "to sum up," or "to think together." An electronic device that accepts input from the user, processes it according to the instructions given to it, and gives the required result in the form of output is a computer.
- The computer has evolved through five generations since its creation.
- The first-generation computers were used between 1946 and 1959.
- The ENIAC computer was a prominent example of this generation.
- Valves (vacuum tubes) were used in their construction, which was large in size and consumed a lot of electricity.
- Excessive electricity usage generated heat, causing frequent shutdowns.
- Modern computers are 5th-generation computers, which are far more advanced, efficient, and compact compared to earlier generations.
Architecture of Computer:
Computer architecture defines the structure and functionality of a computer system. It specifies how hardware components (like CPU, memory, and input/output devices) interact with software to perform tasks. It includes the design, organisation, and operation of the computer.
- Hardware components such as the system unit, monitor, keyboard, and storage devices work together.
- Input devices (e.g., keyboard, mouse, microphone) feed data into the computer, while output devices (e.g., monitor, speakers, printer) display or produce results.
- Storage devices like hard drives, CD/DVD drives, and flash memory store data and programs.
- The architecture determines how efficiently a computer processes data and executes instructions.
