- - - - This might involve formatting data and adding a header according to the protocol such HTTP or FTP.
- - - - recieving
      - Post Office Protocol.
        
        POP receives and holds emails until they are picked up by a user.
        
        When the user checks their email it is downloaded from the server and then deletes it from the server.
        
        The email is then only available locally on the device which the user downloaded it to
    - - recieving
      - Internet Messaging Access Protocol.
        
        This method of receiving emails is more suited to users who have multiple devices.
        
        This is because it maintains a copy of the email on the server until it is deleted by the user.
    - - sending
      - Simple Mail Transfer Protocol.
        
        This protocol allows for emails to be sent between email servers.
        
        This is particularly relevant when the server and recipient have different email providers .
  - - - Transmission Control Protocol/ Internet Protocol.
        
        These are in fact two separate protocols.
        
        TCP is responsible for how messages are broken into packets and reassembled at the destination.
        
        TCP is also responsible for checking for errors and if necessary resends lost packets.
        
        The IP protocol allows for a device to be identified on the internet and allows for appropriate packet routing.
    - - is a network protocol for transmitting files between computers over Transmission Control Protocol/Internet Protocol (TCP/IP) connections.
        
        Within the TCP/IP suite, FTP is considered an application layer protocol.
  - - - Hypertext transfer protocol secure.
        
        Works in a similar way to HTTP but as this data is transmitted it is encrypted.
        
        This is becoming the most common protocol on the world wide web as it gives users peace of mind when entering financial details such as banking or debit/credit card details.
    - - Hypertext transfer protocol.
        
        Requests that the web server transmits the requested web page to the viewer's web browser.
- - - - Using a full mesh network allows for data frames (similar to packets) to be sent via the quickest route.
- - - - Modern computer systems, such as mobile phones and MP3 players, all make use of solid state storage devices. These have no moving parts, which means they can:
        
        Be smaller - devices they are in can be smaller too.
      - Use less battery power - devices they are in stay charged for longer.
      - Be more robust - a magnetic disk could be ruined by dropping it, because its moving parts may be damaged.
    - - Optical storage makes use of a laser to shine and reflect light to read the data stored.
    - - makes use of a magnetizable coating. Magnetized dots are made on the surface of the material.
      - These dots are created, read and erased by very small electromagnets.
