    Study Notes

    Components of a Computer System

    • Hardware includes the physical parts of a computer, peripherals and internal components.
    • Software dictates how the hardware functions.
    • Peopleware: refers to the human element involved in IT, including users and developers.

    Hardware

    • System Units: Desktop computers, notebooks, and mobile devices have different chassis styles.
    • Motherboard: Contains the CPU, RAM, and other components connected through a chipset.
    • Processor: Chips like Intel and AMD are responsible for executing instructions, their performance is measured by factors such as clock speed and core count.
    • Cooling: Processors generate heat and require cooling systems like heat sinks and fans.

    Memory Devices

    • RAM: Volatile main memory used to store data and instructions for the processor.
    • HDD: Nonvolatile storage device, storing data persistently even when the system is off.
    • SSD: Nonvolatile storage device, faster than HDD, using flash memory and offering better power efficiency, ideal for laptops.

    Software

    • Application Software: Designed for specific tasks and user needs, examples include Microsoft Office, web browsers, mobile apps.
    • Categories of Application Software:
      • Productivity Software: For general tasks such as word processing, spreadsheets, presentations.
      • Communications Software: For interacting with others, including email clients and chat applications.
      • Graphics Software: For image editing, design, and video editing.
      • Entertainment Software: For games, movies, and music.
    • Forms of Software Availability:
      • Packaged Software: Mass-produced, commercial software sold in retail settings.
      • Custom Software: Developed specifically for a particular organization or user.
      • Web Application: Accessed through a web browser, hosted online.
      • Open Source Software: Free to use, modify, and distribute.
      • Shareware: Trial version, users pay after a trial period.
      • Freeware: Free to use but may not be free to modify or distribute.
      • Public-Domain Software: Free for any use, modification, or distribution.

    Peopleware

    • Computer Users:
      • Home User: Uses computer for personal tasks like finances, browsing, and entertainment.
      • Small Office/Home Office (SOHO): Small business owners or self-employed individuals, using computers for business-related activities.
      • Mobile User: Employees or students using computers on the go.
      • Power User: Professional users in various industries requiring specific software and high-performance computers.
      • Enterprise User: Part of a large organization with a complex network and high transaction volume.

    Boot Process

    • The boot process is a series of steps that start a computer.
    • The boot process is initiated by turning on the power supply.
    • The BIOS (Basic Input/Output System) is loaded and performs a self-test.
    • The operating system (OS) is loaded from storage.
    • The OS initializes devices, loads drivers, and starts application programs.
    • The user interface is displayed, allowing the user to interact with the system.

    References

    • The reading material includes a list of various websites for further research and understanding.
