Ksivusya [100]

Answer:

HTTP is the application layer protocol required.

Explanation:

For a web page to be displayed on a browser, the seven layers of the OSI model work together. On the application layer, HTTP protocol is used to communicate between the server and the client. The HTTP client is the browser (Chrome, Internet Explorer, Firefox etc.) which sends a request to the HTTP server for accessing a web page.

When a URL is accessed, the HTTP client sends a request to the HTTP server. The server locates the file which is being requested and sends a response message containing the web page which is to be displayed. The exchange of data between the HTTP client and server takes place over a TCP connection.

TCP is a transport layer protocol which provides a reliable connection over which the exchange of data takes place. Data at the transport layer is sent in the form of segments. If the data being sent from the server is too long, it is divided into multiple segments and sent one after the other. The client is then responsible for joining the segments and displaying the information as a web page. The transport layer is also responsible for error correction and detection during the communication process.

If the student is sending or retrieving information from a secure website, the messages being exchanged between the client and server will be encrypted. This means that if a third-party tries to tap the communication process, they would not be able to decipher the messages. This increases the security and helps keep the information present on the web page confidential.

What device is designed specifically to reduce broadcast traffic that passes over a network and to choose the best path for movi

mezya [45]

Answer:

Router

Explanation:

A router is a network device that forwards data packets between networks. Its a network layer hardware device. For example a DSL router that connects to the Internet through an internet service provider.
Router is connects at least 2 networks (can be two LANs) and the ISP.
Router is used to transfer data from one network to another if both networks use same protocols.
It receives data in packets form and forwards the data to another router using a routing table. These data packets can be sent between devices or from devices to the internet.
The routing table is used to choose the optimal path for forwarding the packets between the source and destination hosts. Routing table configure the best route a packet can take to reach its destination using routing protocols. A Routing Protocol defines how routers connect with each other and share information that makes them choose routes on a computer network between source and destination. Routing tables can be configured statically (routes are fed manually) or dynamically (routes are updated based on information obtained from other routers).
Router makes sure that the data packets reach right destination instead of being lost within the network and it also strengthen signals before transmitting them.
Routers reduce broadcast traffic. They form boundaries between broadcast domains and separate a network into multiple broadcast domains.
Router do not broadcast traffic and eliminates the packet when it detects a broadcast address. Routers also stop broadcast messages and don't route a broadcast message between broadcast domains.

How to 5.4.4 on codehs?

iren2701 [21]

The program is an illustration of the square function.

The square function takes a number, and returns the square of the number; i.e. the product of the number twice.

So, the square function in Python, where comments are used to explain each line is as follows:

#This defines the square function

def square(num):

#This returns the square of the argument

return num**2

#This gets input for the number

num = int(input("Number: "))

#This calculates the square of the number

x = square(num)

#This prints the square

print("Square:",x)

You are asked by your supervisor to export NPS configuaration from a server. Your supervisor contacts you and tells you it is mi

Vesna [10]

Answer:

You must import the NPS configurations, then manually cnfigure the SQL Server Logging on the target machine.

Explanation:

The SQL Server Logging settings are not in anyway exported. If the SQL Server Logging was designed on the root machine, the a manually configure of SQL Server Logging has to be done on the target machine after the NPS configurations must have been imported.

Although administrator rights is needed at least to import and export NPS settings and configurations, while that isn’t the issue in this case. NPS configurations are moved to a XML file that is non-encrypted by default. There is no wizard or tool whatsoever to export or import the configuration files.
