Study Notes

Protocols

  • Protocols are sets of rules that govern communication between devices.

Network Components

  • Hub: A simple device that broadcasts data to all connected devices.
  • Server: A device that provides resources and services to other devices on a network.
  • Router: A device that directs data packets between networks.
  • Cables: Physical connections used to transmit data between devices.

Bandwidth and Transmission Speed

  • Bandwidth: The amount of data that can be transmitted over a network in a given time. Measured in bits per second (bps).
  • Bits per Second (bps): A unit of measurement for the rate of data transmission.
  • Buffering: When data arrives at a device slower than it's processed.

Wired vs. Wireless Networks

  • Wired networks: Use physical cables for data transmission. Generally faster and more reliable.
  • Wireless networks: Use radio waves or signals for data transmission. More flexible and convenient.

The Internet

  • The Internet is a global network of interconnected networks.

Protocols and Addressing

  • MAC address: A unique identifier assigned to a network interface card (NIC) on a device.
  • IP address: A unique address assigned to every device on the internet.
  • TCP (Transmission Control Protocol): A protocol that splits messages into smaller packets for transmission and ensures they arrive in order.
  • VoIP (Voice over Internet Protocol): A technology that allows voice communication over the internet.

Data Transmission

  • Packets: Small units of data that large messages are broken into for transmission across networks.

The World Wide Web

  • The World Wide Web is a system of interconnected hypertext documents accessible via the internet.

Internet of Things (IoT)

  • IoT is a network of interconnected devices that connect to the internet, collect and exchange data.
