Master (Primary Device(s)), Slave (Secondary device)
Answer:
A: A ROM chip is non-volatile and will keep its data in the case of a power failure. A RAM chip is volatile and will wipe its data in the case of a power failure.
Explanation:
ROM chips were widely used at the time of the old consoles, because with it you had an extremely fast and non-volatile memory, but this technology is very expensive and started to use CDs in the Consoles, while the RAM memory is a memory of execution random (RAM = RANDOM ACESS MEMORY).

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.
Answer:
A. True.
Explanation:
Authentication in computer technology can be defined as 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 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.
Hence, if the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing.
<em>This simply means that, when a user enters his or her private key (password); the authenticator matches the private key to the uniquely defined credentials. Permission and access is granted by the authorization system right after a successful authentication. </em>
