    Study Notes

    Definition

    • A network is a collection of interconnected devices that communicate and share resources.

    Types of Networks

    1. Local Area Network (LAN)

      • Covers a small geographic area (e.g., home, office).
      • High speed, low latency.

    2. Wide Area Network (WAN)

      • Covers large geographic areas (e.g., cities, countries).
      • Lower speeds, higher latency compared to LAN.

    3. Metropolitan Area Network (MAN)

      • Spans a city or a large campus.
      • Connects multiple LANs within the area.

    4. Personal Area Network (PAN)

      • Small network for personal devices (e.g., Bluetooth connections).

    5. Virtual Private Network (VPN)

      • Secure connection over a public network.
      • Used for secure data transmission and privacy.

    Key Components

    • Nodes

      • Devices connected to the network (computers, printers, servers).

    • Network Interface Card (NIC)

      • Hardware that allows devices to connect to the network.

    • Router

      • Routes data between different networks.

    • Switch

      • Connects devices within the same network and filters traffic.

    • Access Point

      • Allows wireless devices to connect to a wired network.

    • Cabling

      • Physical medium (e.g., Ethernet cables) used for wired connections.

    Network Protocols

    • TCP/IP (Transmission Control Protocol/Internet Protocol)

      • Fundamental communication protocol for the Internet.

    • HTTP/HTTPS (HyperText Transfer Protocol/Secure)

      • Protocol for transferring web pages.

    • FTP (File Transfer Protocol)

      • Protocol for transferring files between devices.

    • SMTP (Simple Mail Transfer Protocol)

      • Protocol used for sending emails.

    Security Considerations

    • Firewall

      • A network security system that monitors incoming and outgoing traffic.

    • Encryption

      • Protects data by converting it into a secure format.

    • Authentication

      • Verifying the identity of users and devices before granting access.

    • Intrusion Detection Systems (IDS)

      • Tools for monitoring network traffic for suspicious activities.

    Network Topologies

    1. Star

      • All nodes connected to a central hub.

    2. Bus

      • All devices share a single communication line.

    3. Ring

      • Each device connects to two others, forming a ring.

    4. Mesh

      • Every device connects to every other device, providing multiple pathways.

    5. Hybrid

      • Combination of different topologies.

    Performance Metrics

    • Bandwidth

      • Amount of data that can be transmitted in a given time.

    • Latency

      • Time taken for a data packet to travel from source to destination.

    • Throughput

      • Actual rate of successful data transfer, often lower than bandwidth due to various factors.

    Common Networking Devices

    • Modem

      • Modulates and demodulates signals for Internet connectivity.

    • Repeater

      • Strengthens signals over long distances to extend network reach.

    • Bridge

      • Connects different network segments, filtering traffic to reduce collisions.

    • 5G Technology

      • Provides faster data speeds and lower latency for mobile and IoT devices.

    • Software-Defined Networking (SDN)

      • Allows network administrators to manage network services through abstraction.

    • Network Function Virtualization (NFV)

      • Virtualizes network services traditionally run on hardware.

    • IoT (Internet of Things)

      • Increasing interconnectivity of everyday devices.
