Answer:

DMT, abbreviation of Dimethyltryptamine, powerful, naturally occurring hallucinogenic compound structurally related to the drug LSD (lysergic acid diethylamide). DMT blocks the action of serotonin (a transmitter of nerve impulses) in brain tissue. It is inactive when taken by mouth and produces effects only when injected, sniffed, or smoked. The hallucinatory action

Explanation:

Major plant genera containing DMT include Phalaris, Delosperma, Acacia, Desmodium, Mimosa, Virola, and Psychotria, but DMT has been found even in apparently innocuous sources, such as leaves of citrus plants (Servillo et al., 2012), and in the leaves, seeds, and inner bark of mimosa tenuiflora

Answer:

DMT — or N, N-dimethyltryptamine in medical talk — is a hallucinogenic tryptamine drug. Sometimes referred to as Dimitri, this drug produces effects similar to those of psychedelics, like LSD and magic mushrooms. Other names for it include: fantasia.

List the components of a typical operating system and summarize the role of each in a single phrase.

yanalaym [24]

Answer:

The answer is below

Explanation:

There are several components of operating systems, this may be based on the specific types of Operating systems. However, here are some of the major components.

1. Kernel: it delivers the primary level of control on all the computer peripherals.

2. Process Execution: it serves as a connection between the hardware and application program

3. Interrupt: it provides a dependable technique for the OS to transmit & respond to their surroundings.

4. Memory Management: it regulates main memory and then moves processes between disk & main memory during implementation.

5. Multitasking: it interprets the activities of many independent computer programs on a similar computer system.

6. Networking: it defines the interaction of processor through communication lines

7. Security: it protects the activities of other processes going in the system

8. User Interface: it provides permission for a computer operator to get the information.

Enabling encryption of all data on a desktop or laptop computer is generally considered:______.

Nezavi [6.7K]

Enabling encryption of all data that are stored on a desktop or laptop computer is generally considered: essential for any computer.

<h3>What is information security?</h3>

Information security can be defined as a preventive practice which is typically used to protect an information system (IS) that use, store or transmit information, from potential theft, attack, damage, or unauthorized access, especially through the use of a body of technologies, encryption, frameworks, processes and network engineers.

<h3>The types of security control.</h3>

In Cybersecurity, there are three (3) different types of security control and these include the following:

Management security.

Physical security.

Operational security.

In this context, we can infer and logically deduce that the use of encryption, endpoint security, firewalls, intrusion detection systems (IDS), and biometric fingerprint readers is generally considered essential for any computer that stores data, unless they aren't sensitive information.

Disk requests come in to the disk driver for cylinders 10, 22, 20, 2, 40, 6, and 38, in that order. A seek takes 6 msec per cyli

oksano4ka [1.4K]

Answer:

For FCFS = 876msec For SSTF = 360msec For SCAN(elevator) = 348msec

Explanation:

Considering FCFS algorithm.

In FCFS, the requests are addressed in the order they arrive in the disk queue, this means that the number of cylinders traveled becomes equal to the total of disk requests. With the arm initially at 20, the first request is to read cylinder 10.

Therefore the cylinders traversed for the first request = 20 – 10 = 10

For the second request i.e. a movement from cylinder 10 to cylinder 22, the number of cylinders traversed is = 22 - 10 = 12.

Similarly, for the third request seek arm will return to 20 from 22 so, cylinders traversed through would be = 22-20 = 2.

Also for the fourth request, cylinders traversed would be = 20 – 2 = 18.

For the fifth request, cylinders traversed = 40 – 2 = 38.

Now for the sixth request cylinders traversed = 40 – 6 = 34.

For the seventh and last request, cylinders traversed = 38 – 6 = 32.

So now to get the how much seek time is required for Disk scheduling algorithm

First we would add the total cylinders traversed = 10 + 12 + 2+ 18+ 38 + 34 + 32

= 146 cylinders

So therefore the total seek time = number of cylinders traversed X seek time per cylinder

= 146 X 6

= 876msec

Considering SSTF algorithm.

In SSTF (Shortest Seek Time First), requests having shortest seek time are executed first. So, the seek time of every request is calculated in advance in the queue and then they are scheduled according to their calculated seek time. What this means is that the closest disk (cylinder) next to the position of the seek arm is attended to first. With the arm at 20 initially, the first request is to read cylinder 22 (i.e. the closest cylinder to the seek arm)

Therefore the cylinders traversed for the first request = 22-20 = 2

For the second request, the disk to focus on is disk 20 and the cylinders traversed = 22-20 = 2

Similarly for the third request the seek arm will move to 10 from 20 so, cylinder traversed = 20-10 =10

For fourth request, cylinder traversed = 10 – 6 = 4

For the fifth request, cylinder traversed = 6 – 2 = 4

For sixth request, since all other disk request closer to it has been attended to the seek arm will move to disk 38 to attend to that disk request So, the cylinder traversed = 38 – 2 = 36

For the last request, cylinder traversed = 40 -38 = 2

So now to get the how much seek time is required for Disk scheduling algorithm

First we would add the total cylinders traversed = 2 + 2 +10 + 4 + 4 + 36 + 2

= 60 cylinders

So therefore the total seek time = number of cylinders traversed X seek time per cylinder

= 60 X 6 = 360msec

From Here we see that SSTF is better or an improvement to FCFS as it decrease the average response time (Average Response time is the response time of the all requests).

Considering SCAN (elevator) algorithm

In SCAN algorithm the disk arm moves into a particular direction and services the requests coming in its path and after reaching the end of disk, it reverses its direction and again services the request arriving in its path. So, this algorithm works as an elevator and hence also known as elevator algorithm. Therefore the number of cylinder traveled becomes equal to the total of disk request. With the arm at 20 initially

The first request is to read cylinder 22 i.e. the first cylinder on the upward movement

Therefore the cylinders traversed would be = 20 – 22 = 2

For the second request is to read cylinder 38, and the cylinders traversed would be = 38 – 22 =16

For the third request, seek arm will move to 40 So, the cylinders traversed would be = 40 – 38 = 2

For the fourth request, seek arm will return to 20 since from 40 since 40 is the highest in this upward elevator movement So, cylinders traversed would be = 40 -20 = 20

For the fifth request, cylinder traversed would be = 20 – 10 = 10

For the sixth request, cylinder traversed would be = 10 – 6 = 4

For the seventh and last request, cylinder traversed = 6 – 2 = 4

So now to get the how much seek time is required for Disk scheduling algorithm

First we would add the total cylinders traversed = 2 + 16 + 2 + 20 +10+ 4 + 4 = 58 cylinders

So therefore the total seek time = number of cylinders traversed X seek time per cylinder

= 58 X 6

= 348msec

From Here we see that SCAN is better or an improvement to FCFS and SSTF as it decrease the average response time (Average Response time is the response time of the all requests).
