Answer:
A class is an good representation of the abstract data type as it is represented independently. For implementing a class, it is use to specify the interface for an abstract class.
Class is one of the type of abstract data type for the objects that whose behavior is basically define by the set of operations and values. It is known as abstract as, it provide an implementation independently.
When the class is using in an abstract data type, then it refers as hidden representation of the data. In this modern era, class is use for the implementation of the abstract data type.
Answer:
The answer is by using a covert channel like shared memory objects such as files, directories,messages, etc since both the user and the sender of the document are on same network of the company.
Explanation:
The Bell LaPadula MultiLevel Security model was a security policy developed by Bell and LaPadula in 1973 in response to a security issue raised by the US Air Force regarding file-sharing mainframe computers . Actually, many people with networked systems have realized by early 1970s that the protection purportedly offered by many commercial operating systems was poor, and wa not getting better any time soon. This was observed when it was noticed that as one operating system error was fixed, some other vulnerability would be discovered. There was also the constant worry that various unskilled users would discover loopholes in the operating system during usage and use them to their own advantage.
Information release may take place via shared memory objects such as files, directories, messages, and so on. Thus, a Trojan Horse acting on behalf of a user could release user-private information using legitimate operating system requests. Although developers can build various mechanisms within an operating system to restrict the activity of programs (and Trojan Horses) operating on behalf of a user , there is no general way, short of implementing nondiscretionary policy models, to restrict the activity of such programs. Thus, given that discretionary models cannot prevent the release of sensitive information through legitimate program activity, it is not meaningful to consider how these programs might release information illicitly by using covert channels.
For example, for someone with higher integrity level (SECRET) to send an accounts payable application to a user, if the untrusted accounts payable application contains a Trojan Horse, the Trojan Horse program could send a (legal) message to the said user process running at a lower integrity level (CONFIDENTIAL), thereby initiating the use of a covert channel. In this covert channel, the Trojan Horse is the receiver of (illegal) lower integrity-level input and the user process is the sender of this input.
I think the order should be 2-1-3-4, but the description of step 1 is confusing. In selection sort, you iterate from the point of the marker down through the entire list and find the smallest value, and swap that with the value at the marker. Then you advance the marker and repeat the process on the remainder of the list.
Answer:
The real world AI application is Google Duplex. It is able to receive orders for making reservations. Then it calls the shop or the place and deals with the person and talks to him very fluently and informs you about the reservation. Some other general types of AI application are Google Assistant, Siri , Amazon Alexa and so on. But google Duplex is lot more advanced than them.
