Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
Answer:
Update the device driver
Explanation:
Devices drivers are softwares used to link a component of the computer to the operating system functionality.
It normally comes with the installed operating system, but most plug and play devices , come with a little built-in OS that runs once it is plugged in.
If a device is not recognized, update the driver software and restart the system.
The answer is A you’re welcome
Answer:
C. user accounts
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure 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
Hence, an access control list primarily is composed of a set of permissions and operations associated with a NTFS file such as full control, read only, write, read and execute and modify.
Generally, access control list are defined for specific user accounts and may either be an administrator, standard user or guest account.
In this scenario, Miriam a network administrator wants to give access rights to employees who are interested in accessing sensitive Information stored on a backup device. Thus, the option Miriam should use is user account.
Answer:
C. Bell and LaPadula
Explanation:
The first mathematical models of multilevel security computer system was developed by Bell and Lapadula. Their full names are David Elliot Bell and Leonard J. Lapadula. Their model used to define the concept of modes of access,secure state machine and outlined the rules of access.
