Cluster computing defines several computers linked on a network and implemented like an individual entity. Each computer that is linked to the network is known as a node.Cluster computing provides solutions to solve difficult problems by providing faster computational speed, and enhanced data integrity. The connected computers implement operations all together thus generating the impression like a single system (virtual device). This procedure is defined as the transparency of the system.Advantages of Cluster ComputingThe advantages of cluster computing are as follows −Cost-Effectiveness − Cluster computing is considered to be much more costeffective. These computing systems provide boosted implementation concerning the ... Read More
GSM represents the Global System for Mobile communication. It is a standard established by the European Telecommunication Standards Institute (ETSI) to define protocols for second-generation (2G) digital mobile networks. It was restored for the first generation (1G) mobile networks. The concept of producing GSM was introduced from a mobile-based mobile radio framework at the Bell Laboratories in the early 1970s.The GSM standard works on three multiple carrier frequencies: the 900 MHz band, which was utilized by the initial GSM system. The 1800 MHz band, which was inserted to provide the multiple subscribers and the 1900 MHz frequency, is used generally ... Read More
Beamforming is also referred to as spatial filtering. It is a signal processing approach used to send or receive radio or sound waves in a directional signal. The applications of beamforming are constructed in radar and sonar systems, wireless connection, and acoustics, and biomedicine supplies.Beamforming and beam scanning are frequently adept by terminology the feed to each component of an array so that signals received or transmitted from all components will be in phase in a specific direction.When transmitting, a beamformer controls the stage and relative amplitude of the signal at each transmitter thus generating a design of effective and ...

IrDA represents the Infrared Data Association. It is a universal consortium of hardware and software manufacturers that generates and supports interoperable solutions for infrared (IR) data networking for computer networks, connections, and different networking applications.Infrared communication contains a transceiver (a set of transmitters and receivers) in both devices that connect. Particular microchips support this effectiveness. Further, several devices can need specific software so that the communication can be synchronized.An example is the special provision for IR in Microsoft's Windows 95 operating frameworks. In the IrDA-1.1 standard, the maximum data size that can be sent is 2048 bytes and the maximum ... Read More
Let us begin by understanding what SSH is.SSHSSH represents Secure Shell or Secure Socket Shell. It is a cryptographic system protocol that enables two computers to connect and send the data over an insecure network including the internet. It can log in to a remote server to implement commands and data transfer from one device to another device.The SSH protocol was established by SSH communication security Ltd to safely connect with the remote device. Secure communication supports powerful password authentication and encrypted connection with a public key over an insecure medium. It can restore unprotected remote login protocols including Telnet, ... Read More
A cookie is a part of data from a website that is saved inside a web browser that the website can fetch at a later time. Cookies are used to communicate the server that users have restored to a specific website. When users restore to a website, a cookie provides data and enables the site to show selected settings and targeted content.Cookies also store data including shopping cart contents, registration or login credentials, and client preferences. This is completed so that when users revisit sites, any data that was supported in an earlier session or any set preferences can be ... Read More
The all() method in the pandas series is used to identify whether any False values are present in the pandas Series object or not. The typical output for this all method is boolean values (True or False).It will return True if elements in the series object all are valid elements (i.e. Non-Zero values) otherwise, it will return False. This means the pandas series all() method checks for whether all elements are valid or not.Exampleimport pandas as pd series = pd.Series([1, 2, 3, 0, 4, 5]) print(series) #applying all function print(series.all())ExplanationHere we have created a pandas series object ...

DataFrame is used to represent the data in two-dimensional data table format. Same as data tables, pandas DataFrames also have rows and columns and each column and rows are represented with labels.By using the python dictionary we can create our own pandas DateFrame, here keys of the dictionary will become the column labels, and values will be the row data.Here we will create a DataFrame using a python dictionary, Let’s see the below example.Example# importing the pandas package import pandas as pd data = {"int's":[1, 2, 3, 4], "float's":[2.4, 6.67, 8.09, 4.3]} # creating DataFrame df = pd.DataFrame(data) ...

The pandas DataFrame constructor will create a pandas DataFrame object using a python list of tuples. We need to send this list of tuples as a parameter to the pandas.DataFrame() function.The Pandas DataFrame object will store the data in a tabular format, Here the tuple element of the list object will become the row of the resultant DataFrame.Example# importing the pandas package import pandas as pd # creating a list of tuples list_of_tuples = [(11, 22, 33), (10, 20, 30), (101, 202, 303)] # creating DataFrame df = pd.DataFrame(list_of_tuples, columns= ['A', 'B', 'C']) # displaying resultant DataFrame ...

In pandas Series functionalities we have a function called add_prefix that is used to add a string prefix to the labels. Particularly in pandas series the row labels will be prefixed with string.The add_prefix method will return a new series object with prefixed labels. It will add the given string before the row labels of the series.Exampleimport pandas as pd series = pd.Series(range(1, 10, 2)) print(series) # add Index_ prefix to the series labels result = series.add_prefix('Index_') print("Prefixed Series object with a string: ", result)ExplanationIn this following example, we have created a pandas series using python range ...
