- - - - A type of cable used in a local area network
      - Positives
        
        Can be used for longer distances than copper cables
        
        Have a higher bandwidth than a copper cable and wireless networks
        
        Less interference than with copper cables or wireless netorks
      - Negatives
        
        Expensive to install and replace
        
        Much more delicate than copper cables
    - - A type of cable used in a local area network
      - Positives
        
        Have dedicated receiving and distribution cables
        
        Cheaper than fiber optic cables
        
        Much easier to install than fibre option - less delicate
      - Negatives
        
        Get more interference than fiber optic cables
        
        Have a lower bandwidth than fiber optic cables
        
        Can't hold a connection over long distances
    - - Allows a computer to connect to a wired network
      - This card is placed in most computers
      - (Think of the Ethernet port on a computer)
  - - - (Think WiFi router or extender - like at home or the ones on the walls at school)
      - Allows a computer to connect to a wireless network
      - Most households, schools and offices use this method
    - - Popular because you don't need cables
      - Portable connection, unlike wired networks
      - It is much cheaper than a wired network
    - - Less secure than a wired connection
      - Signals can be obstructed easily
      - Lower bandwidth than a wired network
- - - - (Transmission Control Protocol) - transmission between routers
    - - (Internet Protocol) - routs packets on a WAN
    - - (Hypertext Transfer Protocol) - requests and delivers HTML files
    - - (Hypertext Transfer Protocol Secure) - encryption and authentication
    - - (File Transfer Protocol) - sending files between computers (uploading web pages)
    - - (Internet Message Access Protocol) - retrieve email from an email server
    - - (Simple Mail Transfer Protocol) - sends mail to a mail server
    - - (Post office protocol) - retrieves emails from servers
