Data cleaning defines to clean the data by filling in the missing values, smoothing noisy data, analyzing and removing outliers, and removing inconsistencies in the data. Sometimes data at multiple levels of detail can be different from what is required, for example, it can need the age ranges of 20-30, 30-40, 40-50, and the imported data includes birth date. The data can be cleans by splitting the data into appropriate types.Types of data cleaningThere are various types of data cleaning which are as follows −Missing Values − Missing values are filled with appropriate values. There are the following approaches to ... Read More

Data mining is the procedure of finding useful new correlations, patterns, and trends by sharing through a high amount of data saved in repositories, using pattern recognition technologies including statistical and mathematical techniques. It is the analysis of factual datasets to discover unsuspected relationships and to summarize the records in novel methods that are both logical and helpful to the data owner.It is the procedure of selection, exploration, and modeling of high quantities of information to find regularities or relations that are at first unknown to obtain clear and beneficial results for the owner of the database.It is not limited ...

The data mining system is integrated with a database or data warehouse system so that it can do its tasks in an effective presence. A data mining system operates in an environment that needed it to communicate with other data systems like a database system. There are the possible integration schemes that can integrate these systems which are as follows −No coupling − No coupling defines that a data mining system will not use any function of a database or data warehouse system. It can retrieve data from a specific source (including a file system), process data using some data ... Read More

Data mining functionalities are used to represent the type of patterns that have to be discovered in data mining tasks. In general, data mining tasks can be classified into two types including descriptive and predictive. Descriptive mining tasks define the common features of the data in the database and the predictive mining tasks act inference on the current information to develop predictions.There are various data mining functionalities which are as follows −Data characterization − It is a summarization of the general characteristics of an object class of data. The data corresponding to the user-specified class is generally collected by a ... Read More

Data mining defines extracting or mining knowledge from huge amounts of data. Data mining is generally used in places where a huge amount of data is saved and processed. For example, the banking system uses data mining to save huge amounts of data which is processed constantly.In Data mining, hidden patterns of data are considering according to the multiple categories into a piece of useful data. This data is assembled in an area including data warehouses for analyzing it, and data mining algorithms are performed. This data facilitates in creating effective decisions which cut value and increase revenue.There are various ... Read More

In this post, we will understand the difference between SATA and PATA −PATAIt stands for Parallel Advanced Technology Attachment.It is a 40 pin connector.It is expensive.The speed of data transfer is low.It consumes more power.The size of the cable is big.It doesn’t come with hot swapping feature.External hard drives can’t be used with PATA.SATAIt stands for Serial Advanced Technology Attachment.It is a 7 pin connector.It is cheap.The speed of data transfer is high.It consumes less power.The size of the cable is small.It comes with the hot swapping feature.External hard drives can be used with SATA.Read More

There are two types of addressing modes, namely, direct addressing mode and indirect addressing mode. In direct addressing mode, the actual address of the data is mentioned in the instructions itself. On the other hand, indirect addressing mode contains the effective address of the memory location where the actual address of the data resides. Read this article to find out more about direct and indirect addressing modes and how they are different from each other. Let's start with a basic introduction of these two types of addressing modes. What is Direct Addressing Mode? The Direct addressing mode is one that ... Read More

In this post, we will understand the difference between USART and UART modes −USART (Universal Synchronous/Asynchronous Receiver/Transmitter)The half-duplex mode is used.The speed of USART is more in comparison to UART.It uses data signals as well as clock to work.The data is transmitted in the format of blocks.It can work similar to UART.It is more complex in comparison to UART.The receiver doesn’t require to know the baud-pace of the transmitter.This is because it gets information by the master and the clock signal.The data is transmitted at a definite (specific) rate.UART (Universal Asynchronous Receiver/Transmitter)It uses full-duplex mode.Its speed is less in comparison ...

Multimedia integrates different forms of content such as text, audio, video, graphics, etc., to form a single presentation. We come across so many different forms of multimedia element on almost every webpage or App that we open. Multimedia is definitely heavy than the traditional static text-based content, but any form of multimedia can immediately attract the users' attention and convey the message quickly.Hypermedia is a mix of hypertext with media such as graphics, sounds, and animations. It can be understood as the improved version of hypertext.Read through this article to find out more about Multimedia and Hypermedia and how they ... Read More

In this post, we will understand the difference between Stack and HeapStackIt is a linear data structure.Memory is allocated in a contiguous (continuous) block.The memory for a stack is allocated and deallocated automatically using the instructions of the compiler.It costs less to build and maintain a stack.It is easy to implement.It is fixed in size; hence it is not flexible.Its only disadvantage is the shortage of memory, since it is fixed in size.If all the blocks are not occupied, memory gets wasted too.It takes less time to access the elements of a stack.It has an excellent locality of reference.HeapIt is ...
