What is Biometrics?

Biometrics


Biometrics is a special method of identifying individuals based on certain unique characteristics of people. Biometrics is an advanced branch of biology that helps in measuring the biological characteristics of humans, such as fingerprints, DNA (Deoxyribo Nucleic Acid), voice, eyeballs, facial images, etc. The main task of biometrics is to find the unique characteristics of each person and to help identify each person individually in light of those characteristics. As early as 500 BC, the Babylonians used fingerprints on small blocks of dried mud for business purposes. In 1891 Juan Vucetich of Argentina started the modern era of fingerprinting by inventing the method of catching criminals.

Biometrics are mainly divided into two categories namely structural and behavioral. Other structural features are human face, fingerprints, hand shape, iris, DNA etc. On the other hand behavioral features are key-stoke, signature, voice and retina etc.

Biometrics works basically using two models. In the first model, data is collected using one-to-one comparison and stored in a database. Later such data is input and compared with the data stored in memory. The second model uses a one-to-many comparison to validate a sample after matching it to the database. In this case, the sample data with least difference is considered correct. Biometrics data can sometimes be confusing, as an employee's DNA collected to identify them can pose a threat to their privacy, such as the DNA data revealing a disease they don't want others to know about.
 

Bioinformatics


Bioinformatics is a system in which information and communication technology, applied mathematics, artificial intelligence and biochemistry are used for biological data analysis. Bioinformatics deals with the analysis of biological problems in theory or practice through the use of databases, algorithms, computers and statistical techniques. Basically, bioinformatics is the application of information and communication technology in the field of molecular biology. Bioinformatics is also developing as the use of information and communication technology increases, which is currently the trend in genomic and other molecular research. Bioinformatics is increasingly used in DNA mapping, analysis, protein sequence extraction and its three-dimensional modeling. Bioinformatics is used in various branches of biology, such as molecular biology, genetics and genomics. Bioinformatics uses computer science, mathematics and engineering to analyze biological data. Complex instruments are used to read biological data. Databases and information systems are used to process all that data. Artificial intelligence, computing, data mining, image processing and simulation algorithms are used to analyze biological data. Software such as C, C++, XML, Peri, Java, Python, spreadsheet applications etc. are also used in data processing.

Important Research Areas: The main objective of research in bioinformatics in various fields is to verify this change. Analyzing the data to understand the structure of a normal cell and how it changes in different diseases can lead to problem solving.

Sequential analysis: helps to generate DNA sequences for comparison between the same species or different species. In this case, computer programs such as BLAST are used.

Explaining the Genome: Dr. Owen White developed the first software system in 1995 to interpret DNA genomes and other biological features. His software helped to find the RNA of the gene. But now advanced software also helps in genomic DNA analysis. Bioinformatics is used in the study of explaining organismal evolution.

What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant ?

Today we talk about What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant .I never like huge introduction about any topic . I always like very shortly introduce any-things to my viewers without any-type boring .So let's began the leanrning :- 1. Decide in advance how many devices you will use. 2. Decide how much space you need coverage. 3. Understand the structure of your home. WiFi signals become weak to penetrate the walls. That is why good coverage is not available. If you have a lot of walls in your house and you want to get coverage in the whole house, then you need a router with high power and wall penetration feature. 4. Decide what features you need in addition to the internet connection. Such as: - 4.1 3G 4G Modem Support- There are many routers that can use the modem. Those routers have a USB port and a one port so that broadband lines can be used. But remember that the modem must have the ability to auto-connect. Not...

What should the processor look at?

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...
