Study Notes

Introduction to Computer

  • A computer is an electronic machine designed for performing calculations and controlling operations expressible in logical or numerical terms.

Applications of Computers

  • Computers have a wide range of applications, including education, industries, government, medicine, scientific research, and the arts.
  • Millions of complex calculations can be performed quickly.
  • Decisions can be reached with accuracy.

Characteristics of Computers

  • Speed: Computers process data at extremely high speeds, handling millions of instructions per second, which far surpasses human capabilities. Speed is measured in MHz.
  • Accuracy: Computers are very accurate, and the degree of accuracy depends on the instructions given and the type of machine.
  • Diligence: Being machines, computers don't get tired or lose concentration, providing consistent performance.

Reliability

  • Reliability is measured against predefined operation standards, meaning the computer should perform tasks without failure.
  • The main memory is small, requiring secondary storage (like tapes or disks) to hold large amounts of information.

Versatility

  • Computers can perform multiple tasks simultaneously efficiently, such as writing, playing music, or printing documents.
  • This ability is possible by changing the program.

Resource Sharing

  • Computers enable the sharing of resources such as printers and data. This creates extensive information and knowledge bases.

Evolution of Computers

  • Early counting methods used fingers and pebbles.
  • The abacus was an early counting device in Asia Minor.
  • Later devices include Napier bones and slide rules.
  • Blaise Pascal invented the first automatic calculator in 1642.
  • Gottfried Wilhelm von Leibniz developed a machine for performing multiplication, division, and finding square roots.
  • Charles Babbage designed calculating machines, known as Difference Engine.
  • Herman Hollerith developed a device which worked for the US census bureau.
  • Further advancements used electrical components to perform calculations, culminating in the modern computer.
  • Mark I was the first electronic calculator with relays and electromagnetic components.
  • The main elements from the 1940s to 1950s were vacuum tubes in electronic components. (ENIAC, EDVAC, and UNIVAC)
  • Later, transistors and integrated circuits improved speed, size, and energy efficiency.
  • The introduction of microprocessors, led to the fourth and fifth generations.

Computer Generations

  • First Generation (1940-1956): Vacuum tubes for circuitry, magnetic drums for memory; Punched cards input and printouts output.
  • Second Generation (1956-1963): Transistors, smaller, more portable, less heat generation.
  • Third Generation (1964-Early 1970s): Integrated circuits, faster, smaller, more reliable.
  • Fourth Generation (early 1970s till today): Microprocessors, very large-scale integration. Extremely fast, compact.
  • Fifth Generation (Present): Artificial Intelligence, features of expert systems (that emulate human reasoning), parallel processing.
  • Computer advancements generally resulted in smaller computers with more capabilities.

Computer Classification

  • Four major categories: Micro, Mini, Mainframe, and Super computers (based on size and capabilities).
  • Microcomputers: Personal computers (desktops and laptops).
  • Minicomputers: smaller but more powerful than microcomputers.
  • Mainframes: High-performance computers for large-scale data processing.
  • Supercomputers: The most powerful and fastest computers designed for specialized jobs, like scientific research or modeling.

Computer Hardware

  • Physical components of a computer system, including monitors, mice, keyboards, and storage devices.
  • Input devices gather information.
  • Output devices display or produce results from computer processing.
  • Includes physical components like memory, hard drives, and processing units.

Computer Software

  • Instructions enabling a computer to perform specific tasks.
  • System software manages hardware components. (example: Operating Systems, Device drivers, Language Translators)
  • Application software performs tasks for users. (example: word processors, spreadsheets, graphics software)

User Interface (UI)

  • How a user interacts with a computer system.
  • Graphical User Interface (GUI): Uses visuals (windows, icons, menus) for input.
  • Command-line Interface (CLI): Text-based, requiring commands for interaction..
  • Menu-driven Interface: Uses menus to guide users in completing tasks.
  • Form-based Interface: Data input through forms or structures.

Windows Operating System

  • Multitasking operating system with a graphical user interface.
  • Key components include Desktop, Taskbar, Start Menu, My Computer, Recycle Bin.

Internet

  • Global network interconnecting computers.
  • Communication Services: Enable data exchange (e.g., VoIP, email).
  • Information Retrieval Services: Allow searching and access to information (e.g., Web services).
  • File Transfer: Enabling movement of data across networks (e.g., FTP).
  • Directory Services: Providing organizational information about services and resources (e.g., DNS).

MS Word

  • A word processing program included in MS Office suite.

MS PowerPoint

  • A presentation software for creating slide shows.
