Study Notes
Definition of Computer
- A computer is a device that processes data, performing calculations and operations according to software or hardware instructions.
- It integrates hardware and software components to execute applications for varied solutions.
- Primary components include hardware (physical parts) and software (program instructions).
Key Categories of Computers
- Hardware: Includes the processor, memory, storage, communication ports, and peripherals.
- Software: Comprises the operating system (OS) and application software.
Evolution of Computers
- Birth resulted from a need for efficient data processing, such as in the 1880 U.S. Census.
- Notable figures include Charles Babbage, who created the Analytical Engine.
- Types include personal computers, laptops, minicomputers, mainframes, and supercomputers.
Generations of Computers
- First Generation (1937-1946): Introduced vacuum tubes; included the Atanasoff-Berry Computer (ABC) and ENIAC.
- Second Generation (1947-1962): Transition to transistors; featured the UNIVAC 1 and IBM 650; development of over 100 programming languages.
- Third Generation (1963-Present): Integration of circuits, resulting in smaller, more powerful machines; emergence of Microsoft DOS and the IBM PC.
Computer Fundamentals
- A computer accepts, processes, and outputs data.
- Input includes raw facts such as words, numbers, and images, while output is the processed information.
Types of Computers
- Supercomputer: Most powerful, used for complex tasks; very expensive.
- Mainframe: Large and powerful, used in enterprise settings; also expensive.
- Personal Computer (PC): Widely used for daily tasks; includes both Macs and PC compatibles.
Hardware Components
- Input Devices: Allow data entry; includes keyboard, mouse, scanner, microphone, and digital camera.
- Output Devices: Deliver processed information; includes monitor, printer, and speakers.
Software Overview
- Software consists of instructions for the computer; divided into system software (operating systems) and application software (specific tasks).
- Common OS includes Windows and Mac; applications like Microsoft Word and Excel facilitate daily tasks.
Storage Media
- Stores data for future use; examples include hard drives and floppy disks.
- The process of writing saves data, while opening files retrieves it.
Computer Care
- Essential to clean both internal and external components.
- Regular dusting, avoiding food, maintaining clean hands, and proper usage help prolong computer lifespan.
Internet Basics
- The internet connects computers globally, enabling data exchange; originated from ARPANET.
- Opened to broader access when universities and institutions connected, leading to the development of the World Wide Web.
Internet Connection Types
- Dial-Up: Cost-effective but slow; uses phone lines.
- DSL: Digital Subscriber Line provides constant connectivity; ranges from 128 kbps to 8 mbps.
- Cable: Offers faster speeds via cable TV lines; ranges from 512 kbps to 20 mbps.
Notable Figures in Internet Development
- Vint Cerf, a co-designer of TCP/IP protocols, earned recognition as a "Father of the Internet."
- Tim Berners-Lee invented the World Wide Web, facilitating user-friendly navigation and data display.
