Flashcards

LAN

A local area network that covers a small geographical area, such as a home, office, or campus. It typically has high-speed bandwidth and a single administration.

WAN

A wide area network that connects LANs over large geographical areas, like cities or countries. It's managed by multiple service providers, often with slower speeds.

Network Components

The various parts that make up a network. These include end devices—where communication originates or ends (e.g., computers, phones)—intermediary devices—that manage the flow of data (e.g., routers, switches)—and media types—how data travels (e.g., copper, fiber optics).

Network Reliability

Characteristics of a reliable network include fault tolerance (redundancy to handle failures), scalability (growing without performance loss), quality of service (prioritizing data), and security (protecting the network).

Study Notes

Introduction to Networks

  • Networks facilitate global communication, learning, work, and entertainment.
  • Communication methods include texting, social media, online collaboration, blogs, and gaming.

Types of Networks

  • LAN (Local Area Network): Covers a small area (home, office, campus) with high-speed, single administration.
  • WAN (Wide Area Network): Spans large areas (cities, countries), managed by multiple providers, slower speeds than LANs.
  • Internet: A global network composed of interconnected LANs and WANs, using copper, fiber optic, and wireless connections.

Network Components

  • End Devices: Devices where messages begin or end (computers, phones).
  • Intermediary Devices: Manage data flow (routers, switches, firewalls).
  • Media Types: Copper cables, fiber optics, wireless technologies.

Network Architectures

  • Fault Tolerance: Redundancy in network design to minimize disruptions.
  • Scalability: The ability to expand the network without performance issues.
  • Quality of Service (QoS): Prioritizes certain data types (e.g., video, voice).
  • Security: Protecting network infrastructure and data (confidentiality, integrity, availability).
  • BYOD (Bring Your Own Device): Employees using personal devices for work.
  • Cloud Computing: Storing and accessing data over the internet (public, private, hybrid).
  • Online Collaboration and Video Communication: Tools like Cisco WebEx and TelePresence.
  • Smart Homes: Integration of technology into domestic appliances.

Security

  • Threats: Risks to networks include external threats (viruses, hacking, Denial-of-Service attacks) and internal threats (employee errors or malicious intent).
  • Solutions: Home networks use antivirus and firewalls; large networks employ access control lists, intrusion prevention systems, and virtual private networks (VPNs).

Key Terms

  • Topology: The physical or logical layout of a network.
  • NIC (Network Interface Card): Connects a device to the network.
  • Packet Switching: Dividing data into packets for efficient and resilient transmission.
