There are six categories of security services: authenticiation, access control, data confidentiality, data integrity, nonrepudiation, and availability service. First, is authentication service, which defines as the assurance that the communicator is legitimate and is the one that it claims to be. It can either be peer entity or data origin authentication. Second, access control which is to prevent any unauthorized uses of resources. After one is being authenticiated, then this service limit/controls who access? what accessing rights to the resources are allowed depending on the identified individuals. Data confifentiality: the protection of data from unauthorized disclosure. Data integrity: the assurance that data received are exactly as sent by an authorized entity (e.t.c, contain no modificafion, insertion, deletion, or replay).
Answer:
A lot can happen, depending on the use of the variable
Explanation:
Lets create a position variable, a common variable in games.
Vector3 position = new Vector3(0, 0, 0);
The above variable initialization creates a new Vector3 object. The Vector3 class contains 3 properties, X, Y, and Z. When you assign the variable 'position' the new Vector3 object, the variable 'position' contains an instance of Vector3 where
X = 0,
Y = 0,
and Z = 0.
The variable 'position' can be used to set the position of a player, or an object.
We can reuse this variable when you want the object or player to move.
position.X = 29
position.Y = -14
position.Z = 47
now the object/player's position is (29, -14, 47).
Variables can be used for basically everything you need in programming, from storing a position, to storing the result of a complex math equation.
