- 2Transmission Control Protocol (TCP)On the senders side, the TCP will break the data being sent into smaller data packets. On the recipients side the TCP will reassemble the packets into the complete data. It also checks for errors in the data packets and requests any that have errors to be resent.
- 3Internet Protocol (IP)After the data is broken into packets by the TCP, the IP will identify the IP address for the packets of data and direct them to the recipient over the internet.
- 4File Transfer Protocol (FTP)This is the protocol that allows us to transfer files between two computers across a TCP-based network, like the internet. We normally use it to download large files such as software programs from the internet, but it is also used to upload web pages to a hosting server on the internet so others can see your website.
- 5Cloud-Based SoftwareSoftware applications that run on the host servers and we can access through the use of our browser.
- 6Cloud-Based StorageA service that allows us to store all of our files on the hosting company’s computers rather than on our own personal computer.

- 22Full BackupThis is where all files and folders on a hard disk are backed up. Each time the backup is run a new complete copy of all the files and folders is taken.
- 23Incremental BackupThis is where only files and folders that are new or have changed since the last backup was run are backed up.
- 24Differential BackupThis is where only files and folders that are new or have changed since the last FULL backup was run are backed up. So a full backup is run first and then we run differential backups following this.
- 25Error Control BitsThis checks that the packets have been reassembled correctly.
- 26Coded DataThe actual piece of the overall data that we are sending in the packet that can then be reassembled with the other packets at the destination.
