Pandas series has a method for calculating absolute values of series elements. That function can also be used for calculating the absolute values of a series with complex numbers.The abs() method in the pandas series will return a new series, which is having calculated absolute values of a series with complex numbers.The absolute value of a complex number is $\sqrt{a^{2}+b^{2}}$ whereas a is the real value and b is the imaginary value of a complex number.Example# importing pandas packages import pandas as pd #creating a series with null data s_obj = pd.Series([2.5 + 3j, -1 - 3.5j, 9 ...

The abs function of the pandas series will return a series with absolute numeric values of each element. This abs function will calculate the absolute values for each element in a series.This function only works for a series objects if it has numerical elements only. it doesn’t work for any missing elements (NaN values), and it can be used to calculate absolute values for complex numbers.Exampleimport pandas as pd # create a series s = pd.Series([-3.43, -6, 21, 6, 1.4]) print(s, end='') # calculate absolute values result = s.abs() #print the result print(result)ExplanationWe have a simple ...

The head() method in the pandas series is used to retrieve the topmost rows from a series object. By default, it will display 5 rows of series data, and we can customize the number of rows other than 5 rows.This method takes an integer value as a parameter to return a series with those many rows, suppose if you give integer n as a parameter to the head method like head(n) then it will return a pandas series with n number of elements. And those elements are the first n number of elements of our pandas series object.Example# importing required ... Read More
Pandas series is a one-dimensional ndarray type object which stores elements with labels, those labels are used to addressing the elements present in the pandas Series.The labels are represented with integers, string, DateTime, and more. Here we will see how to access the series elements if the indexes are labeled with DateTime values.Exampleimport pandas as pd # creating dates date = pd.date_range("2021-01-01", periods=5, freq="D") # creating pandas Series with date index series = pd.Series(range(10, len(date)+10), index=date) print(series) print('') # get elements print(series['2021-01-01'])ExplanationThe variable date is storing the list of dates with length 5, the starting date ...

Let us understand what a network administrator is.Network AdministratorNetwork administration includes a large array of operational functions that support a network to run smoothly and accurately. Network administrators who work in network administration areas, jobs involve complex functions including designing networks for multiple systems, their management, troubleshooting, documentation, providing security, backup, and storage, and also handling the clients.A network administrator will frequently check data to make certain the system is optimized and will view problems that can either be generated by the network or another user.It can provide new users who have been trained accurately in network usage and train ...

First, let us understand what File Transfer Protocol (FTP) is.FTPFTP represents File transfer protocol. FTP is a standard internet protocol supported by TCP/IP used for sharing the records from one host to another. FTP needs TCP as a transport protocol to help the reliable end-to-end connections and executes two types of connections in managing data transfers.The FTP clients initiate the first connection, referred to as the control connection, to well-known port 21 (the client’s port is typically ephemeral). It is on this element that an FTP server listens for it and approaches new connections. The control connection is expressed for ... Read More
Let us begin by learning about Over the Top (OTT) video streaming.OTTOTT stands for Over the Top Video streaming. It can be applied by anyone over the internet connection. Some OTT content can be produced by an open ecosystem. Its monthly cost is relatively low as compared to several internet networks.This term is used to define the content provider that allocates streaming media directly to viewers over the web, bypassing multiple platforms like telecommunication, broadcast television, multichannel that facilitate as a controller or distributor of such content.IPTVIPTV stands for Internet Protocol television. It is the process of communicating and broadcasting ... Read More
NGN stands for Next Generation Network. It defines the evolution and migration of hooked and mobile network frameworks from distinct proprietary networks to assemble networks depending on IP. It is accepted to be an interworking environment of heterogeneous networks of wired and wireless access networks, PSTN, satellites, transmission, etc.Next-generation networks are used to send all types of services and data such as voice data/calls, audio data/calls, and multimedia data including videos. All types of such data are encapsulated in data packet design.An NGN is simply based on Internet technology, such as MPLS and IP. It uses H.323 protocol as its ... Read More
Let us understand what a digital video recorder DVR is.DVRDVR stands for Digital Video Recorder. It is a recording device that records video in a digital structure and saves it on hard drives instead of videotapes. It needed video signals to be digitized and compressed to save as many days’ worth of video feed as available.Security systems using DVRs play an important role in alarm verification and security assessment. The digital video images are saved on hard disks similar to those used in the PCs and have storage areas calculated in gigabytes. It provides a cheap but efficient technique for ... Read More
Gigabit Ethernet is a variant of the Ethernet technology generally used in local area networks (LANs) for sending Ethernet frames at 1 Gbps. It can be used as a backbone in several networks, especially those of large organizations.Gigabit Ethernet is an enlargement to the earlier 10 Mbps and 100 Mbps 802.3 Ethernet standards. It provides 1, 000 Mbps bandwidth while supporting full compatibility with the set up base of around 100 million Ethernet nodes.Gigabit Ethernet usually employs an optical fibre connection to share records at a very huge speed over high distances. For short distances, copper cables and twisted pair ... Read More
