Answer:
Option (D) is the correct answer of this question.
Explanation:
Moore's Law relates to Moore's theory that the number of transistors on a microchip doubles every two years while device costs are halved.
Interpretations of Moore's law assert the computing power doubles every 18 months.The Moore's Law theory states that development is exponential.Moore's Law states that every couple of years we should expect our computers to increase their speed and capacity and we'll pay less for them.h
Option(A),Option(B) ,Option(c) and option(E) do not belongs to Moore's law so these options are incorrect options.
Answer:
Key escrow.
Explanation:
If a full disk encryption (FDE) password is forgotten, a key escrow can be incorporated to securely store the encryption key to unlock the disk.
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.
Hence, the cryptographic keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
<em>Therefore, when a full disk encryption (FDE) password is forgotten, a key escrow if incorporated can be used to retrieve the password. Subsequently, the password would then be used to unlock or decrypt the disk.</em>
Answer: D)It relies on two independent proofs of identity.
Explanation: Two factor authentication is technique which uses two steps/stage for the verification or authentication.It is done for the extra security maintenance.IT is also known as 2FA. It consist of two different authentication component so that it penetrates through double protection layer .
Other options are incorrect because It RSA public key cannot be used for the authentication of private content. It does not use both hand geometry at same time for both the levels and It does not utilize only single sign-on technology. Thus, the correct option is option(D).
Answer: /sbin
Explanation:
In Linux, FHS describes the directory content and the way in which Operating System files are displayed to the user.
/sbin is a directory that contains executable programs. s/bin is the short form of system binaries. System binaries require root rights to perform specific tasks. /sbin contains binaries that are crucial to boot the system and also to recover and restore the system. /bin directory also contains the commands to boot the system but the main difference between both is that /sbin programs can only be executed by the root user. Examples are fdisk, fsck, root,halt, init, grub, ifconfig.
the answer is E. ............
