Study Notes
Definition and History
- A computer is an electronic device that takes in information, processes it, and produces output.
- The first electronic computer was developed in the 1940s.
- Charles Babbage is credited with inventing the first mechanical computer, the Analytical Engine, in the early 19th century.
Components
-
Hardware: physical parts of a computer, including:
- Central Processing Unit (CPU): executes instructions
- Memory (RAM): temporary storage for data and programs
- Storage Drive: permanent storage for data and programs
- Input/Output Devices: keyboard, mouse, monitor, etc.
-
Software: programs and operating systems that run on the hardware, including:
- Operating System: manages hardware and provides interface for user
- Application Software: performs specific tasks, such as word processing or web browsing
Types of Computers
- Desktop Computers: designed for individual use, typically stationary
- Laptop Computers: portable, designed for individual use
- Mobile Devices: smartphones and tablets, designed for mobile use
- Servers: high-performance computers that manage networks and provide services
- Mainframe Computers: large, powerful computers used by organizations for data processing and storage
- Supercomputers: extremely powerful computers used for scientific and research applications
Functions
- Input: receiving data and instructions from user
- Processing: executing instructions and performing calculations
- Storage: storing data and programs
- Output: displaying or producing results
- Control: managing and coordinating computer operations
Impact and Applications
