• Machine Learning:
  • Subset of AI that enables machines to learn from data
  • Types: supervised, unsupervised, and reinforcement learning

Cybersecurity

• Threats:
  • Malware: viruses, worms, Trojans, spyware
  • Phishing: fraudulent emails, texts, or messages
  • Ransomware: encrypts data, demands payment for decryption
• Security measures:
  • Firewalls: block unauthorized access to a network
  • Encryption: protects data from unauthorized access
  • Strong passwords and authentication: prevent unauthorized access

Computing

• Hardware Components:

  • CPU (Central Processing Unit): The main processor that executes program instructions, often referred to as the "brain" of the computer.
  • RAM (Random Access Memory): Temporary memory storage that allows for fast data access while the computer is on, crucial for performance.
  • Storage Devices:
    • Hard Drives: Traditional spinning disks for data storage.
    • Solid State Drives (SSDs): Faster storage alternatives with no moving parts, offering quicker access to data.
    • Flash Drives: Portable storage devices for easy data transfer.

• Software Types:

  • Operating Systems (OS): Software that manages hardware and provides a user interface, major examples include Windows, macOS, and Linux.
  • Productivity Software: Applications designed to facilitate tasks, including Microsoft Office and Google Suite.
  • Web Browsers: Programs for accessing the internet, with popular options being Google Chrome, Mozilla Firefox, and Safari.

Internet and Networking

• Internet: A vast global network connecting millions of private, public, academic, business, and government networks, enabling communication and the sharing of information.

• Networking Concepts:

  • LAN (Local Area Network): Networking infrastructure that connects computers and devices in a limited geographical area such as a home or office.
  • WAN (Wide Area Network): Connects multiple LANs over larger distances, often using leased telecommunication lines.
  • Wi-Fi: A technology allowing devices to connect to the internet or communicate wirelessly within a limited area.

Artificial Intelligence and Machine Learning

• Artificial Intelligence (AI): The simulation of human intelligence by machines, enabling them to perform tasks that typically require human cognition. Key applications include:

  • Virtual Assistants: AI programs that can perform tasks based on voice commands.
  • Image Recognition: Technology that allows computers to identify and process images.
  • Natural Language Processing: Enables machines to understand and respond to human language.

• Machine Learning: A subset of AI focused on developing algorithms that allow computers to learn from and make predictions based on data. Various types include:

  • Supervised Learning: Model training with labeled datasets.
  • Unsupervised Learning: Finding patterns in data without pre-existing labels.
  • Reinforcement Learning: Learning through trial and error to achieve a goal.

Cybersecurity

• Common Threats:

  • Malware: Malicious software, including types like viruses, worms, Trojans, and spyware, designed to harm or exploit any programmable device.
  • Phishing: Tactics used to deceive individuals into providing sensitive information through fraudulent communications.
  • Ransomware: A specific type of malware that locks user data and demands payment for access.

• Security Measures:

  • Firewalls: Security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules, protecting networks from unauthorized access.
  • Encryption: The process of converting information into a code to prevent unauthorized access, ensuring data security.
  • Strong Passwords and Authentication: Best practices to enhance security, making it difficult for unauthorized users to gain access to systems or data.
