Answer:
In a sentence: data is raw numbers, while information is organized data.
Explanation:
Data is a series of numbers or facts. A data set is a collection of data that are related (for examples all the students result in your last math exam). But it's not organized by itself... and rarely mean anything when looked at it in a raw manner.
To make sense of a data collection, you have to analyze it, calculate the mean or median of the data set for example... this is a treatment that has to be done to a data set to give it significance.. after such analysis, the result you have (mean, median, etc..) is a piece of information devired from the data.
Answer:
Discretionary Access Control model
Explanation:
Discretionary Access Control (DAC) gives owners of a resource full control of objects/items they have created or been given access to, this also includes sharing the objects/items with other subjects. These owners have control over their data and maintain access through ACLs. The access-control list (ACL), is a list of permissions attached to an object in a computer file system.
The Owners can decide to grant other users access to their files, change their attributes, alter them, or delete them. DACs are discretionary because the owner can transfer information access to other users.
Answer:
a) true.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
On the other hand, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.
Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.
<em>Hence, in cybersecurity the use of encryption and authentication protocols is the standard method of countering attempts to alter or insert transmissions. </em>
3D printing helps to reduce the time it takes for a manufacturer to create the product. This lets manufacturers invest their time to make flawless products because the production cycle time is reduced.
False because if you edit the ownership of file it will give permissions only with the permissions you can edit file,rename,or delete file.
