    Study Notes

    Introduction to Information Technology

    • Information technology (IT) encompasses the tools, techniques, and processes used to manage, store, retrieve, and process data.
    • It is a broad field encompassing various software and hardware components.
    • IT systems are crucial for businesses, organizations, and individuals to operate efficiently and effectively.

    Hardware Components

    • Computers and related devices form the foundation of IT infrastructure.
    • Key hardware components include:
      • Central Processing Unit (CPU): The "brain" of the computer, performing calculations and instructions.
      • Random Access Memory (RAM): Stores data and instructions currently in use.
      • Hard Disk Drive (HDD) and Solid State Drive (SSD): Permanent storage for data.
      • Motherboards: Connects all components together.
      • Input devices: Keyboard, mouse, scanner, microphone.
      • Output devices: Monitor, printer, speakers.
      • Network Interface Card (NIC): Enables computers to connect to a network.
    • Peripheral devices expand computer capabilities.

    Software Components

    • Software dictates how hardware functions.
    • Types of software include:
      • Operating Systems (OS): Manage computer resources (e.g., Windows, macOS, Linux).
      • Application Software: Performs specific tasks (e.g., word processors, web browsers, games).
      • Programming Languages: Allow developers to create software (e.g., Python, Java, C++).
    • Software development life cycles (SDLC) are crucial for creating and implementing new software.

    Networking

    • Networking connects computers and devices to share resources and communicate.
    • Types of networks include:
      • Local Area Networks (LANs): Connect devices within a limited geographic area.
      • Wide Area Networks (WANs): Connect devices across a large geographic area (e.g., the internet).
    • Protocols like TCP/IP govern data transmission over networks.
    • Network security is paramount to protect data and systems from unauthorized access or damage.

    Data Management

    • Data management involves organizing, storing, and retrieving data.
    • Databases are used to structure and manage large amounts of data.
    • Database management systems (DBMS) are software systems that manage databases.
    • Data integrity ensures that data is accurate and reliable, with appropriate protocols in place.

    Cloud Computing

    • Cloud computing delivers computing resources (servers, storage, software) over the internet.
    • Offers scalability, flexibility, and cost-effectiveness.
    • Types of cloud services include:
      • Infrastructure as a Service (IaaS): Provides basic computing resources.
      • Platform as a Service (PaaS): Offers a platform for developing and deploying applications.
      • Software as a Service (SaaS): Delivers software over the internet (e.g., webmail, online office suites).

    Cybersecurity

    • Cybersecurity protects computer systems and data from threats.
    • Threats include:
      • Viruses, malware, and ransomware
      • Phishing and social engineering attacks
      • Denial-of-service (DoS) attacks
      • Data breaches
    • Security measures include:
      • Firewalls
      • Antivirus software
      • User authentication
