Data Transfer Methods

Data Transfer Methods

1. Internet

   • The internet is a very lage, global network using public telecommunications
   • Almost anyone can use the internet so any data transferred over the internet is not very secure
   • Other Networks can be connected to transfer data between networks

2. Connecting Networks

   • Networks are used to transfer data between computing devices
   • Wired networks can be expensive to set up as the cost of installation and cables can be high for large networks
   • Wireless networks use radio waves to connect devices via a wireless access point and are easy to set up.
     • Portable devices such as smartphones and laptops have built-in wireless network cards and can easily connect to a wireless network.
   • Networks can be connected using cables that go to each computing device

3. Connecting while mobile or travelling

   • Many hotels, cafes and shops offer free wireless networking to their guests and customers but some make a high charge for it
   • Mobile phones, smartphones and other portable devices can use mobile phone telecommunication networks, called 3G or 4G networks, to connect to networks and the internet.
   • 3G or 4G networks offer much slower speeds than wired or wireless networks. 4G networks have a greater bandwidth than 3G networks

4. Emails

   • Emails are sent from a device such as a smartphone
   • They are sent to an email server which sends the emails to other servers and then to the email inbox of the recipient
   • Email was originally designed for sending simple messages but it is now possible to attach files.
   • Emails such as photographs, documents and video for sharing with others
