In computer networks, Gigabit Ethernet (GbE) is the family of Ethernet technologies that achieve theoretical data rates of 1 gigabit per second (1 Gbps). It was introduced in 1999 and was defined by the IEEE 802.3ab standard.Varieties of Gigabit EthernetThe popular varieties of fast Ethernet are 1000Base-SX, 1000Base-LX, 1000BASE-T and 1000Base-CX.1000BASE-CXDefined by IEEE 802.3z standardThe initial standard for Gigabit EthernetUses shielded twisted pair cables with DE-9 or 8P8C connectorMaximum segment length is 25 metresUses NRZ line encoding and 8B/6B block encoding1000BASE-SXDefined by IEEE 802.3z standardUses a pair of fibre optic cables of a shorter wavelength having 770 – 860 nm ...

Setting up CookiesIt is very easy to send cookies to browser. These cookies are sent along with HTTP Header before to Content-type field. Assuming you want to set UserID and Password as cookies. Setting the cookies is done as follows −#!/usr/bin/python print "Set-Cookie:UserID = XYZ;\r" print "Set-Cookie:Password = XYZ123;\r" print "Set-Cookie:Expires = Tuesday, 31-Dec-2007 23:12:40 GMT;\r" print "Set-Cookie:Domain = www.tutorialspoint.com;\r" print "Set-Cookie:Path = /perl;" print "Content-type:text/html\r\r" ...........Rest of the HTML Content....From this example, you must have understood how to set cookies. We use Set-Cookie HTTP header to set cookies.It is optional to set cookies attributes like Expires, Domain, and Path. ... Read More

In this tutorial, we will learn about looping techniques in python 3.x. Or earlier. There are many ways in which we can implement loops. Here we will be discussing four techniques in looping.Enumeration constructExample Live Demo# enumerate() type for index, value in enumerate(['Tutorial', 'point']): print(index, value)Output0 Tutorial 1 pointZip constructExample Live Demo# zip() method arr1 = ['Tutorial', 'point'] arr2 = ['python', 'loops'] for i, j in zip(arr1, arr2): print(i, j)OutputTutorial python point loopsMembership constructExample Live Demo# membership operator for i in ['Tutorial', 'point']: print(i)OutputTutorial pointInfinitive constructExample# infinite loop while(True): passStep - based constructExample# range with step incrementer For i ...

In this article, we will learn about K’th Non-repeating Character in Python using List Comprehension and OrderedDict. To do so we take the help of inbuilt constructs available in Python.Algorithm1. First, we form a dictionary data from the input. 2. Now we count the frequency of each character. 3. Now we extract the list of all keys whose value equals 1. 4. Finally, we return k-1 character.Examplefrom collections import OrderedDict import itertools def kthRepeating(inp, k): # returns a dictionary data dict=OrderedDict.fromkeys(inp, 0) # frequency of each character for ch in inp: ...

In this article, we will learn about the four iterator functions available in Python 3.x. Or earlier namely accumulate() , chain(), filter false() , dropwhile() methods.Now let’s look on each of them in detail −Accumulate () & chain() methodAccumulate() method takes two arguments, one being iterable to operate on and another the function/operation to be performed. By default, the second argument performs the addition operation.Chain() method prints all the iterable targets after concatenating all of the iterables.The below example explains the implementation −Example Live Demoimport itertools import operator as op # initializing list 1 li1 = ['t', 'u', 't', 'o', 'r'] ...

In this article, we will learn about convolutions in Python 3.x. Or earlier. This articles come under neural networks and feature extraction.Ide preferred − Jupyter notebookPrerequisites − Numpy installed, Matplotlib installedInstallation>>> pip install numpy >>>pip install matplotlibConvolutionConvolution is a type of operation that can be performed on an image to extract the features from it by applying a smaller container called a kernel/coordinate container like a sliding window over the image. Depending on the values in the convolutional coordinate container, we can pick up specific patterns/features from the image.Here, we will learn about the detection of horizontal and vertical endpoints in ...

In this article, we will learn about the Internal working of Set in Python. We will observe the union and intersection operation in different frames and objects.Let’s declare an empty set.>>> s=set()Now let’s declare a set with elements.>>> s1=set('tutorialspoint')Adding an element into an empty set.>>> s.add(‘p’)Now we declare another set with the name of Python.>>> s2=set('python')Now let’s see the union operation.>>> s3=s1.union(s2)Finally, we implement the intersection option.>>> s4=s1.intersection(s2)ConclusionIn this article, we learned about the Internal working of Set in Python 3.x. Or earlierRead More
In this article, we will learn about the internal working of python & how different objects are allocated space in the memory by the python interpreter.Python is an object-oriented programming construct language like Java. Python uses an interpreter and hence called an interpreted language. Python supports minimalism and modularity to increase readability and minimize time and space complexity. The standard implementation of python is called “cpython” and we can use c codes to get output in python.Python converts the source code into a series of byte codes. So within python, compilation stage happens, but directly into byte code and this ... Read More
