Answer:

Option D: If it is the month of January, then the temperature is cool.

Explanation:

A conditional statement is the one having an if condition in it that says, if the condition is true proceed to the next statement, else not.

Given statements are:

If it is the month of January, then it is winter.

This can be written as: if (January)⇒Winter

If it is winter, then the temperature is cool.

This can be written as: if (winter)⇒ Temperature(cool)

So by combining both the statements, the winter clause will be connected and we get:

if(January)⇒Temperature (cool)

This can be written as:

If it is the month of January, then the temperature is cool.

So, Option D is the correct answer.

i hope it will help you!

Furkat [3]

Answer:

Aaron could expect a diversity in the style of the sheep drawings.

Explanation:

Crowdsourcing is a simply a sourcing model in which an individual or organizations get goods and services, ideas and finances, from a large, relatively open and often rapidly growing group of internet users.

It makes it easier for participants to achieve a cumulative result through working differently on the same project. That is to say, it provides work between participants to achieve a cumulative result.

Its benefits is that, Crowdsourcing allows businesses to perform tasks more quickly than when a single employee is working alone. Again, Breaking up a project into a collection of smaller pieces and providing these pieces to a larger group of workers hastens the completion of projects. Overall, crowdsourcing presents a more efficient way to do work.

From the Question, Aaron was able to get different pictures of sheep in their numbers also because he used crowsourcing on amazon.

He got a variety of pictures and so many in such a short time for his project "The Sheep Market".

The OSI model is a useful tool in troubleshooting a network because it enables you to isolate a problem to a particular software

lutik1710 [3]

Answer:

1) Layer 4, transport

2) Layer 2, datalink

3) Layer 5, session

4) Layer 7, application

Description of Problems are as below:

1) One of your servers has been exhibiting sluggish network performance. you use a network-monitoring program to try to evaluate the problem. You find considerable TCP retries occurring because the server is being overwhelmed by data, and packets are being discarded.

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Explanation:

OSI Model is a reference model to determine how applications communicate over a network. OSI consists of seven layers, and each layer performs a particular network function. The seven layers are:

Layer 7 - Application.

Layer 6 - Presentation.

Layer 5 - Session.

Layer 4 - Transport.

Layer 3 - Network.

Layer 2 - Data Link.

Layer 1 - Physical.

Layer 4, transport

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

Layer 2, Data Link

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

Layer 5, session

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Layer 7, application

Describe the concepts of confidentiality, integrity, and availability (C-I-A), and explain each of the seven domains of a typica

GREYUIT [131]

Answer:

Answer explained below. The remaining part of the question is incomplete

Explanation:

The concepts of confidentiality, integrity, and availability (C-I-A) can be explained in following given points.

1) Confidentiality: Its basically refer to the confidentiality of the information. Here we can think about the protection of the information from unauthorized person. Confidentiality enuser that at what level your information is secured and no unauthorized access will be done to the information. For maintaining the confidentiality, we can use various encryption methods. The main concept of confidentiality is to enforce various techniques like encryption, file permissions and access control to restrict access to important information.

2) Integrity: Integrity of the information refer to the unwanted modification of the information. Integrity of the data as well as the information should be maintained and only the autorized person can access as well as modify the information. For enforcing the integrity, we can implement various hashing techniques on information.

3) Availability: Availability refers to the availability of the information, when ever an autorized person requests for the information. High availability of the information should occur, so that any autorized person can access it, when ever its required. For high availability, we can create backup as well as replicate the data across the geo sites.

Seven domains of a typical IT infrastructure are given below:

1) User Domain: Its refer to the group of users as well as the person who access the information systems.

2) LAN Domain: Refer to the local area network, where various computers are connected to each other.

3) Workstation Domain: The area is called workstation, where various users connect to the IT infrastructure.

4) WAN and LAN link domain: Refer to the connection of local area network to wide area network.

5) WAN domain: Refer to the wide area network, connection of computers in large area.

6) Storage Domain: Refer to the storage, where we store the data.

7) Remote Access Domain: Refer to the domain where mobile user can access the local as well as wide network remotely.
