mariarad [96]

Solution:

The five Layers in Internet protocol stack are:

1.Application Layer  

2.Transport Layer  

3.Network Layer  

4.Link Layer  

5.Physical Layer  

The principal responsibilities of these layers are as follows:

1.Application Layer •Applications with appropriate requirement for user.  

•It is reserved for network applications and their application protocols such as HTTP, SMTP, and FTP etc.  

•Its protocol uses transport layer protocols for establishing host-to-host connection.  

2.Transport Layer  

•It is responsible for End-to-Communication  

•Transport layer transports messages from application layer between client and server of application  

•It uses two protocol for transporting messages: TCP and UDP.TCP provides reliable connection oriented services, while UDP provides connectionless service  

3.Network Layer  

•Network Layer moves packets from one host to destination.

•It has two principal component:IP protocol:-It defines the datagrams and decide how the end system and router will work Routing protocols: these protocols decide the routing path between source and destination. 4.Link Layer  

•It is responsible for link-level communication  

•Link layer receives the data gram from network layer at each node and delivers it to next node, the next node passes the datagram to network layer.so This layer moves entire frames from one network element to adjacent one.

•The service provided by link layer is protocol dependent

5.Physical Layer  

•It provides Physical media

•At each node, it moves individual bits of frames to next node.

Which of the following is a valid IP address that can be used on the Internet (meaning the public addressing scheme)? Group of a
VladimirAG [237]

Answer:

168.16.1.1 is correct.

Explanation:

168.16.1.1 is the legitimate Internet Protocol address that can be used on the Internet.

Internet Protocol 10.10.1.1 and internet Protocol 172.30.1.1 are the private internet protocol addresses so they could not be used on the internet.

The Internet Protocol 234.1.1.1 has been used as a multicast address so they may not be used on the Internet.

What is the purpose behind the Three Phase Commit? It improves upon the two phased commit by requiring that locks be acquired at
Ray Of Light [21]
The answer is a) It improves upon the two-phased commit by requiring that locks be acquired at the start of a transaction.

Reason: The 3PC is an extension or you can say developed from 2PC that avoids blocking of an operation. It just ensures that first n sites have intended to commit a transaction that means it acquires commits or locks before the start of any transaction to avoid any blocking.

Option b) is wrong as it does not allow coordination, it just let all the other sites do their transaction if any other site is blocked, so no coordination is there between sites that they will wait till their coordinator is corrected.

Option c) is wrong as lock operations are shared between other connections as when their coordinator fails, the new coordinator agrees to the old coordinator that they had shared locks before and they can start their transaction.

Option d) is wrong as option a) is correct.

Assume the variable sales references a float value. Write a statement that displays the value rounded to two decimal points.Assu
romanna [79]

Answer:

The statement is as follows:

print("{0:,.1f}".format(number))

Explanation:

Required

Statement to print 1234567.456 as 1,234,567.5

To do this, we make use of the format keyword, and we set the print format in the process.

To round up number to 1 decimal place, we use the following format:

"{0:,.1f}"

To include comma in the thousand place, we simply include a comma sign before the number of decimal place of the output; i.e. before 1

"{0:,.1f}"

So, the print statement is:

print("{0:,.1f}".format(number))
