    • Central Processing Unit (CPU) comprises millions of transistors that represent binary values (1s and 0s).
    • CPUs are embedded in motherboards, linking to essential hardware and peripherals like speakers and modems.

    Data Submission and Storage

    • Input devices for data processing: keyboard, modem (for network connectivity), and scanner (for digitizing printed information).
    • Memory storage options:
      • ROM chips: Store permanent and frequently used data.
      • RAM chips: Store changeable data.
    • Mass storage devices:
      • Hard drives for large data storage.
      • Flash drives for portable data, connecting via USB.

    Software Functionality

    • Software includes:
      • Boot sequence instructions guiding startup processes.
      • Operating systems (e.g., Microsoft Windows, Apple's OS) running user applications and providing GUIs.

    Operating System Developments

    • Microsoft Windows improved upon DOS by introducing GUIs, a central registry, and advancing from 32-bit to 64-bit computing.
    • Apple’s OS utilizes "point and click" navigation; frequent upgrades enhanced graphic capabilities and data storage.
    • UNIX OS serves as a stable base for Internet functions with a kernel, shell interface, and diverse applications. LINUX and Android are notable open-source variations.

    Malware and Security

    • Malware types include viruses, Trojan horses, and worms can exploit operating system vulnerabilities.
    • Anti-virus software and firewalls are essential for mitigating malware threats, while newer threats like droppers and logic bombs emerge continuously.

    Internet and Networking

    • Internet grew with browser advancements, connecting users via Internet Service Providers (ISPs).
    • Key networking terms:
      • Routers: Facilitate network connections.
      • Hubs: Strengthen and pass along communications.
      • Packets: Units of data exchanged between computers.
      • Cookies: Data reflecting user preferences to enhance user experience.

    Networking Concepts

    • Domain Name System (DNS) utilizes IP addresses to define networked computers.
    • Peer-to-peer networking allows direct connections between computers with roles as client and server, often ensuring user anonymity.
    • Cloud computing transforms traditional models to a service-centered approach using internet servers for data storage.

    Types of Networks

    • Intranets: Limited access local networks within specific organizations.
    • Internets: Larger networks that encompass several smaller networks.
    • The Internet: The largest global computer network.

    Internet Connection Speeds

    • Dial-up connections are measured in bands, whereas modern high-speed connections (cable, satellite, DSL) are measured in megabits per second.

    Web Navigation

    • The World Wide Web connects various Internet sites, typically recognized by unique URLs associated with domain names.
    • Older digital communication formats included electronic bulletin boards (BB) and Internet Relay Chat (IRC), each facilitating user interaction while handling anonymity differently.

    Evolution of Computing

    • Calculating machines are early predecessors to modern computers, dating back centuries.
    • Computer technology transitioned from vacuum tubes to solid-state processors, enhancing efficiency and power.
    • Data entry evolved from paper tapes to graphic user interfaces (GUIs) like Microsoft Windows.
