which of the following specifies how data on the internet should be formatted, addressed, transmitted, routed and received?

Answers

Answer 1

Data should be structured, addressed, transported, routed, and received over the internet using one of two transmission types: parallel transmission or serial transmission.

What are the fundamental guidelines for data transfer via the Internet?

Data is never transferred "as such," which is a fundamental rule of how data (files, emails, web pages, and other types of data) are transmitted across the Internet and a distinguishing characteristic of the TCP/IP protocols that are used to do so.

What is the most effective Internet transport protocol?

Transmission Control Protocol (TCP) is the most popular transport protocol (TCP). It gave the entire Internet Protocol Suite, TCP/IP, its name. It is used for connection-oriented transmissions, whereas the User Datagram Protocol (UDP) is used for connectionless transmissions of basic messaging.

What will be the different if the syringes and tube are filled with air instead of water?Explain your answer

Answers

Answer:

If the syringes and tubes are filled with air instead of water, the difference would be mainly due to the difference in the properties of air and water. Air is a compressible gas, while water is an incompressible liquid. This would result in a different behavior of the fluid when being pushed through the system.

When the syringe plunger is pushed to force air through the tube, the air molecules will begin to compress, decreasing the distance between them. This will cause an increase in pressure within the tube that can be measured using the pressure gauge. However, this pressure will not remain constant as the air continues to compress, making the measured pressure unreliable.

On the other hand, when the syringe plunger is pushed to force water through the tube, the water molecules will not compress. Therefore, the increase in pressure within the tube will be directly proportional to the force applied to the syringe plunger, resulting in an accurate measurement of pressure.

In summary, if the syringes and tube are filled with air instead of water, the difference would be that the measured pressure would not be reliable due to the compressibility of air.

An if statement must always begin with the word “if.” True False python

Answers

Answer:

true

Explanation:

The given statement is true, that an if statement must always begin with the word “if.” in python.

What is the python?

A high-level, all-purpose programming language is Python. Code readability is prioritized in its design philosophy, which makes heavy use of indentation. Python uses garbage collection and has dynamic typing.

It supports a variety of paradigms for programming, including functional, object-oriented, and structured programming. An “if” statement must always be the first word in a sentence.

One of the most often used conditional statements in computer languages is the if statement in Python. It determines whether or not particular statements must be performed. It verifies a specified condition; if it is true, the set of code included within the “if” block will be run; if not, it will not.

Therefore, it is true.

The third assignment involves writing a Python program to compute the cost of carpeting a room. Your program should prompt the user for the width and length in feet of the room and the quality of carpet to be used. A choice between three grades of carpeting should be given. You should decide on the price per square foot of the three grades on carpet. Your program must include a function that accepts the length, width, and carpet quality as parameters and returns the cost of carpeting that room. After calling that function, your program should then output the carpeting cost.
Your program should include the pseudocode used for your design in the comments. Document the values you chose for the prices per square foot of the three grades of carpet in your comments as well.
You are to submit your Python program as a text file (.txt) file. In addition, you are also to submit a test plan in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.

Answers

Answer:

# price of the carpet per square foot for each quality.

Given the two vectors u = <6, -2, 1> and v = <1, 8, -4> a) Find u * v, and find u*v

b) Find angle between vectors u and v.

c) Graph both u and v on the same system.

d) Now, graph vectors u, v and on the same set of axes and give u * v a different color than vectors u and v.

e) Rotate graph from part d and show two different views of the cross product.

f) Find the normal vector to vector u.

Answers

a) To find the dot product of the vectors u and v, we can use the Dot function in Mathematica. The dot product is calculated as follows:

u.v = Dot[u, v]

b) To find the angle between vectors u and v, we can use the ArcCos function in Mathematica. The angle is calculated as follows:

angle = ArcCos[(u.v)/(Norm[u]*Norm[v])]

c) We can graph both vectors u and v on the same system using the ListVectorPlot3D function in Mathematica. This will display the vectors in a 3D coordinate system.

ListVectorPlot3D[{u, v}]

d) To graph vectors u, v, and u * v on the same set of axes with different colors, we can use the Graphics3D function in Mathematica. We can assign a different color to u * v using the Directive function.

Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],

 Directive[Red], Arrow[{{0, 0, 0}, u*v}]}]

e) To rotate the graph from part d and show two different views of the cross product, we can use the ViewPoint option in the Graphics3D function. By specifying different viewpoints, we can obtain different perspectives of the graph.

Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],

 Directive[Red], Arrow[{{0, 0, 0}, u*v}]},

ViewPoint -> {1, -1, 1}]

To convert the given grammar to Chomsky Normal Form (CNF), we need to follow a few steps:

Step 1: Eliminate ε-productions (productions that derive the empty string).

Step 2: Eliminate unit productions (productions of the form A → B).

Step 3: Convert long productions (productions with more than two non-terminals) into multiple productions.

Step 4: Convert terminals in remaining productions to new non-terminals.

Step 5: Ensure all productions are in the form A → BC (binary productions).

Applying these steps to the given grammar:

Step 1: Eliminate ε-productions

The given grammar doesn't have any ε-productions.

Step 2: Eliminate unit productions

The given grammar doesn't have any unit productions.

Step 3: Convert long productions

S → AB

A → aAAa

B → bBb

B → bb

C → CC

C → a

Step 4: Convert terminals

No changes are needed in this step as all terminals are already in the grammar.

Step 5: Ensure binary productions

The given grammar already consists of binary productions.

The converted grammar in Chomsky Normal Form (CNF) is:

S → SS | AB

A → aAAa

B → bBb | bb

C → CC | a

D → aC | bb

Note: The original grammar didn't include the production rules for the non-terminals 'S', 'C', and 'D'. I assumed the missing production rules based on the provided information.

Cache memory is typically positioned between the CPU and the hard drive. A cache memory is used by a computer's central processing unit to reduce the average cost time or energy required to access data from the main memory.

What is Cache memory ?

Cache memory is a chip-based computer component that improves the efficiency with which data is retrieved from the computer's memory. It serves as a temporary storage area from which the computer's processor can easily retrieve data.

A cache is a hardware or software component that stores data in order to serve future requests for that data more quickly; the data stored in a cache may be the result of an earlier computation or a copy of data stored elsewhere.

When the requested data can be found in a cache, it is called a cache hit; when it cannot, it is called a cache miss. Cache hits are served by reading data from the cache, which is faster than recalculating a result or reading from a slower data store; as a result, the more requests that can be served from the cache, the faster the system performs.

Caches must be relatively small in order to be cost-effective and enable efficient data use. Nonetheless, caches have proven useful in a wide range of computing applications because typical computer applications access data with a high degree of locality of reference.
