Computer Networks

  • A network is a collection of computers, servers, peripherals, and other devices which are interconnected to share information and resources
  • Two main types of computer networks are LAN (Local Area Network) and WAN (Wide Area Network)
  • LANs connect devices in a small area, such as a building or office
  • WANs connect devices over a large geographical area, such as a country or continent

Internet Protocols

  • Protocols are rules governing data exchange between devices
  • TCP/IP is a family of protocols for communication between computer devices
  • TCP/IP stands for Transmission Control Protocol/Internet Protocol
  • Defines how electronic devices connect and transmit data across the internet

Internet Addressing

  • Each device connected to the internet is assigned a unique IP address
  • IP Version 4 (IPv4) addresses are 32-bit numbers expressed in dotted-decimal notation
