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
Let us understand what a campus area network (CAN) is.CANCAN stands for campus area network. It is a network of several interconnected local area networks (LAN) in a finite geographical location. It is smaller than a wide area network (WAN) or metropolitan area network (MAN).In CAN, the same technology along with the hardware is used in multiple buildings of one campus or one association. They follow similar terminologies such as the local area networks but the change is that they are interconnected between the several buildings at the specific location.Campus Area networks are cost-effective, beneficial, and simple to implement in ...

Let us begin by understanding what McAfee is.McAfeeMcAfee is the most used antivirus solution provider and has been in use because of the first advertise of viruses. McAfee supports a complete range of security products including antivirus, firewall, and anti-spyware programs. McAfee Antivirus occurs with a set of features that will maintain your computer free of viruses, worms, Trojans, and several malicious codes.McAfee also merges a restrained full-screen feature, which stops all antivirus notifications from being advertised while full-screen applications are running, so it won't prevent your work.The Secure File Shredder feature is another helpful feature, which will enable you ...

A pandas Series holds labeled data, by using these labels we can access series elements and we can do manipulations on our data. However, in some situations, we need to get all labels and values separately.Labels can be called indexes and data present in a series called values. If you want to get labels and values individually. Then we can use the index and values attributes of the Series object.Let’s take an example and see how these attributes will work.Exampleimport pandas as pd # creating a series s = pd.Series({97:'a', 98:'b', 99:'c', 100:'d', 101:'e', 102:'f'}) print(s) # Getting ...

Pandas Series can be created in different ways, here we will see how to create a pandas Series object with a python list.To create a pandas series we have pandas.Series() function from pandas functionalities.Let’s take an example and create a simple pandas Series using a python list. In order to create a pandas series from the python list, firstly we need to define a python list object.Exampleimport pandas as pd # defining a list list_of_values = [2, 89, 34, 78, 3] # creating series s = pd.Series(list_of_values) print(s)ExplanationIn the above code, we have imported the pandas package using ...

Both NumPy and pandas are essential tools for data science and machine learning technologies. We know that pandas provides DataFrames like SQL tables allowing you to do tabular data analysis, while NumPy runs vector and matrix operations very efficiently.pandas provides a bunch of C or Cython optimized functions that can be faster than the NumPy equivalent function (e.g. reading text from text files).If you want to do mathematical operations like a dot product, calculating mean, and some more, pandas DataFrames are generally going to be slower than a NumPy array. since pandas is doing a lot more stuff like aligning ...

To represent a data table in pandas we have a table-like object in pandas which is DataFrame. A DataFrame is a 2-dimensional data structure in pandas and those data structures can store any kind of data in column and row wise representation.Exampledf = pd.DataFrame({"Name": [ "Harris", "William", "Elizabeth", ], "Age": [22, 35, 58], "Sex": ["male", "male", "female"], }) print(df)ExplanationHere we created a data table in pandas manually by using the DataFrame object and the data is a dictionary of lists. While creating the tabular data we only mentioned the column labels but yet mentioned any row labels (index value). But ... Read More
