Answer:

B. Least privilege                

Explanation:

  • The principle of least privilege an important principle in computer security.
  • It limits the access rights for users and only grant them with the rights that are sufficient for them to perform their required task.
  • For example a user is granted privilege to execute a file or manipulate data or use only the resources that are required for them to perform a particular task.
  • This principle can be used only to limit and control access rights to system resources and applications.
  • The least privilege is beneficial as it reduces the risk of unauthorized access.
  • For example a user whose task is data entry and has nothing to do with controlling access or granting access rights to users, will only be allowed to enter data to the DB by the principle of least privilege.

4. In this problem, we consider sending real-time voice from Host A to Host B over a packet-switchednetwork (VoIP). Host A conve
mina [271]

Answer:

The time elapsed is 0.017224 s

Solution:

As per the question:

Analog signal to digital bit stream conversion by Host A =64 kbps

Byte packets obtained by Host A = 56 bytes

Rate of transmission = 2 Mbps

Propagation delay = 10 ms = 0.01 s

Now,

Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.

Time taken to generate and convert all the bits into digital signal is given by;

t = \frac{Total\ No.\ of\ packets}{A/D\ bit\ stream\ conversion}

t = \frac{56\times 8}{64\times 10^{3}}          (Since, 1 byte = 8 bits)

t = 7 ms = 0.007 s

Time Required for transmission of the packet, t':

t' = \frac{Total\ No.\ of\ packets}{Transmission\ rate}

t' = \frac{56\times 8}{2\times 10^{6}} = 2.24\times 10^{- 4} s

Now, the time elapse between the bit creation and its decoding is given by:

t + t'  + propagation delay= 0.007 + 2.24\times 10^{- 4} s + 0.01= 0.017224 s

What type of printer heats toner to adhere it to the paper? inkjet . impact. 3D. laser.
Luden [163]

Answer:

laser

Explanation:

These are well known printer types now.  Let's review how they work to determine in which does heat plays a role.

inkjet: inkjet printers are printer throwing ink at the paper in the form of little drops.  No heat involved here.

impact: That's the oldest technology, where a printing head is moving left and right to punch a printing ribbon and transfer ink onto the paper.  No heat involved.

3D: 3D printers don't usually use paper... as they use other materials to create a 3D representation of a model.  Heat is involved in the melting of the material before it's placed on the building model.  But no paper involved here.

laser: laser printers are working very much like a photocopier machine... memorizing the pattern to be printed, then transferring it onto paper... using heat.
