When an Ethernet frame arrives at a computer, the Ethernet layer must hand the packet that it contains to the next higher layer

to be processed. The act of finding the right higher layer to pro-cess received packets is called demultiplexing. We know that in our case the higher layer is IP. But how does the Ethernet protocol know this? After all, the higher-layer could have been another protocol entirely (such as ARP). We have the same issue at the IP layer – IP must be able to deter-mine that the contents of IP message is a TCP packet so that it can hand it to the TCP protocol to process. The answer is that protocols use information in their header known as a "demultiplexing key" to determine the higher layer. O true O false

Answer: The answer is True.

Explanation:

In the TCP/IP suite, when travelling through a physical network, information comes encapsulated in frames, which format depends on the Data Link Layer Protocol used.

For Ethernet networks, there is a special field, called TYPE, that once read by the software, informs to the Ethernet software to which higher layer must send the packet, once stripped the frame header.

This field TYPE is known as a "demultiplexing key" for the Data Link Layer Protocol.

At the IP level, the IP header contains a similar field, called PROTOCOL in IPv4 and NEXT HEADER in IPv6, which acts in the same way, telling to the IP software which is the higher layer to send the datagram, once stripped the IP Header.

One foot equals 12 inches. Write a function named feet_to_inches that accepts a number of feet as an argument and returns the nu
fenix001 [56]

Answer:

def feet_to_inches( feet ):

      inches = feet * 12

      print(inches, "inches")

feet_to_inches(10)

Explanation:

The code is written in python.  The unit for conversion base on your question is that 1 ft = 12 inches. Therefore,

def feet_to_inches( feet ):

This code we define a function and pass the argument as feet which is the length in ft that is required when we call the function.

inches = feet * 12

Here the length in ft is been converted to inches by multiplying by 12.

print(inches, "inches")

Here we print the value in inches .

feet_to_inches(10)

Here we call the function and pass the argument in feet to be converted

Which type of app is the best choice when it is critical to be able to use the device's features but performance is not critical
lisov135 [29]

Answer:

Hybrid.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are; planning, analysis, design, development (coding), testing, implementation and execution, and maintenance.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

Basically, softwares are categorized into three (3) main categories based on the development platform and these are;

a. Web application.

b. Native application.

c. Hybrid application.

A hybrid application is a type of software application that is designed based on the combination of the elements of both web applications and native applications.

Typically, a hybrid application is a web application that is developed in a native application shell, using a standardized web programming language such as CSS, JavaScript, and HTML.

Generally, a hybrid application avails a programmer the opportunity to write a code for a mobile application once while accommodating or being compatible with multiple app platforms such as Android, Windows, iOS, etc.

Hence, a hybrid application is the best choice of an application when it's critical for the end users to be able to use the features associated with a device such as a mobile phone but performance isn't critical.
