=**__Define Standard Protocol, Data Integrity and Data Security__**= __Protocols__
 * In order for two computers to understand what they have to send and receive there are set of protocols
 * A protocol is an agreed set of rules for the communication process
 * Protocols determine the following:
 * The type of error checking
 * Data compression method
 * How the sending device will start and finish the message
 * How the receiving node will indicate that it has received the package

__Standard protocol__
 * A standard protocol is a protocol that the two computers have agreed on and that manages the communication between the two ends of a network
 * the Standard protocol manages the syntax and synchronization of the communication.
 * The important thing for the user is that the computer understands the most important types of protocols

__Data integrity__
 * Data integrity means that the data reaches its destination without being modified along the way.

__Data security__
 * It is important to protect data because it can be accesses by anyone within a network
 * the main ways to protect data is by:
 * **A user name / password combo** that only allow access to data if the correct password has been entered
 * **Data encryption**where the data is encrypted so no one other than the authorized users can read the data
 * encrypted data is usually password protected by some form of program
 * **User rights** so only specific users / administrators have access to data
