What is JavaScript ? | Comingfly

What is JavaScript ?  JavaScript is  Developed in the mid-1990s as a tool to improve on web development practices, JavaScript has since become one of the most widely utilized languages in that field. It is a high-level and dynamically typed language that is flexible and multi-paradigm. Although its applications in machine learning have been limited, high profile projects like Google’s Tensorflow.js are based on JavaScript. One of the most promising features of JavaScript in the field of machine learning is that it opens up opportunities for web and front-end developers, who are largely already well acquainted with it and thus have an accessible point of entry into an otherwise somewhat obscure and difficult niche. As it exists now, however, the ecosystem for machine learning with JavaScript is still somewhat immature, so support for this type of development is currently limited. It also lacks the range of functionality for data science that languages like R and Python already...

Top 5 Programming Languages Use For Machine Learning | Comingfly

Top 5 Programming Languages Use For Machine Learning Machine learning has been defined by Andrew Ng, a computer scientist at Stanford University, as “the science of getting computers to act without being explicitly programmed.” It was first conceived in the 1950s, but experienced limited progress until around the turn of the 21st century. Since then, machine learning has been a driving force behind a number of innovations, most notably artificial intelligence. 1. Python Developed by the Python Foundation in the early 1990s, Python is a high-levelprogramming language that has many different uses, including data science and back-end web development. As a powerful data analysis tool, it is widely used in big datatechnology, and a strong community of machine learning developers have helped elevate its status in the burgeoning field of artificial intelligence. Due to this vibrant community, there are already many pre-built libraries for machi...

What is Python ? Developed by the Python Foundation in the early 1990s, Python is a high-level programming language that has many different uses, including data science and back-end web development. As a powerful data analysis tool, it is widely used in big data technology, and a strong community of machine learning developers have helped elevate its status in the burgeoning field of artificial intelligence. Due to this vibrant community, there are already many pre-built libraries for machine learning in Python. And Python is platform agnostic, meaning that it is adaptable to virtually any operating system. It is also open source, which makes it very accessible to the general public. Python is a dynamically typed language, which can create problems in machine learning environments. For one, errors can become difficult to track as the program grows larger and more complex. This can create costly drawbacks and also slow down performance. Also developed in the early 1990s, R is part of t...

What is PageRank (PR) ? | Comingfly

What is PageRank (PR) ? PageRank ( PR) is an algorithm used by Google Search to rank websites in their search engine results. PageRank was named after Larry Page, one of the founders of Google. PageRank is a way of measuring the importance of website pages. According to Google: It is not the only algorithm used by Google to order search engine results, but it is the first algorithm that was used by the company, and it is the best-known. Algorithm The PageRank algorithm outputs a probability distribution used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for collections of documents of any size. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes, called “iterations”, through the collection to adjust approximate PageRank values to more close...

What is Secure Sockets Layer (SSL) Certificate | comingfly

What is Secure Sockets Layer (SSL) Certificate Secure Sockets Layer (SSL) is the predecessor of Transport Layer Security (TLS), which is a cryptographic protocol for secure Internet data transmission. Secure Sockets Layer (SSL) is a standard protocol used for the secure transmission of documents over a network. Developed by Netscape, SSL technology creates a secure link between a Web server and browser to ensure private and integral data transmission. SSL uses Transport Control Protocol (TCP) for communication. In SSL, the word socket refers to the mechanism of transferring data between a client and Server over a network. When using SSL for secure Internet transactions, a Web server needs an SSL certificate to establish a secure SSL connection. SSL encrypts network connection segments above the transport layer, which is a network connection component above the program layer. SSL follows an asymmetric cryptographic mechanism, in which a Web browser creates a public key and a private (...

Components Of Computer Network | Comingfly

Components Of Computer Network Major components of a computer network are: 1. NIC(National interface card) NIC is a device that helps the computer to communicate with another device. The network interface card contains the hardware addresses, the data-link layer protocol use this address to identify the system on the network so that it transfers the data to the correct destination. There are two types of NIC: wireless NIC and wired NIC. Wireless NIC:  All the modern laptops use the wireless NIC. In Wireless NIC, a connection is made using the antenna that employs the  radio wave technology . Wired NIC:  Cables use the  wired NIC  to transfer the data over the medium. 2. Hub Hub is a central device that splits the network connection into multiple devices. When computer requests for information from a computer, it sends the request to the Hub. Hub distributes this request to all the interconnected computers. 3. Switches Switch is a networking d...

What is Computer Network ? | Comingfly

What is Computer Network ? Uses Of Computer Network Resource sharing:  Resource sharing is the sharing of resources such as programs, printers, and data among the users on the network without the requirement of the physical location of the resource and user. Server-Client model:  Computer networking is used in the  server-client model . A server is a central computer used to store the information and maintained by the system administrator. Clients are the machines used to access the information stored in the server remotely. Communication medium:  Computer network behaves as a communication medium among the users. For example, a company contains more than one computer has an email system which the employees use for daily communication. E-commerce:  Computer network is also important in businesses. We can do the business over the internet. For example, amazon.com is doing their business over the internet...

Business Loans | Comingfly

Bank Term Loans for Small Business A  basic commercial bank loan  is called a bank term loan or a commercial loan. A bank term loan has a particular term or length of maturity and usually a fixed  interest rate . The repayment of the principal of bank term loans are usually  amortized , which means that the principal and interest are set up as equal periodic payments designed to pay off the loan in the specified period of time. In the past, small businesses have lived and died on the strength of bank loans, their primary source of small business financing. During the Great Recession of 2008, this somewhat changed as banks became more reticent to lend and small businesses had to start looking at alternative sources of financing. Types of Bank Term Loans The  American Bankers Association  generally recognizes two types of bank term loans. The first is the intermediate term loan which usually has a maturity of one to three years. It is often used to finan...
