Top 10 Trending Technologies To Master In 2019
Top 10 Trending TechnologiesChange is the only constant. This applies in your professional life as well. Up-scaling yourself is a need nowadays, the reason is pretty simple, technology is evolving very quickly. I have listed top 10 trending technologies, which is expected to acquire a huge market in 2019.Artificial IntelligenceBlockchainAugmented Reality and Virtual RealityCloud ComputingAngular and ReactDevOpsInternet of Things (IoT)Intelligent Apps (I – Apps)Big DataRPA (Robotic Process Automation)So, the countdown begins from here.10) RPA (Robotic Process Automation):Generally, any desk job in any industry involves tasks that are repetitive in nature and can be automated.RPA or Robotic Process Automation allows you to automate such routine and repetitive tasks. You don’t need to write any code to automate repetitive tasks.In 2019, the trend of bots and machine learning is only going to skyrocket, which means RPA will become an invaluable skill to have.9) Big Data:Big data refers to problems that are associated with processing and storing different types of data. Most of the companies today, rely on big data analytics to gain huge insight about their:customer,product research,marketing initiatives and many more.For your surprise, big data led Germany to win the world cup.Hadoop and Spark are the two most famous frameworks for solving Big Data problems.If you already have some knowledge of Big Data, splendid! If not, now is the time to start.8) Intelligent Apps (I – Apps):I-Apps are pieces of software written for mobile devices based on artificial intelligence and machine learning technology, aimed at making everyday tasks easier.This involves tasks like organizing and prioritizing emails, scheduling meetings, logging interactions, content, etc. Some familiar examples of I-Apps are Chatbots and virtual assistants.As these applications become more popular, they will come with the promise of jobs and fat paychecks.7) Internet of Things (IoT):IoT essentially is connecting many devices and creating a virtual network where everything works seamlessly via a single monitoring center of sorts.IoT is a giant network of connected devices – all of which gather and share data about how they are used and the environments in which they are operated.This includes everything from your:mobile phones,refrigerator,washing machines to almost everything that you can think of.With IoT, we can have smart cities with optimized:traffic system,efficient waste management andenergy useSo, start thinking of some new excuse for coming late to the office other than traffic.6) DevOps:This is the odd one out in the list. It is not a technology, but a methodology. DevOps is a methodology that ensures that both the development and operations go hand in hand. DevOps cycle is picturized as an infinite loop representing the integration of developers and operation teams by:automating infrastructure,workflows andcontinuously measuring application performance.It is basically the process of continual improvement, so why not start with yourself.5) Angular and React:OK, now we are getting into core tech.Angular and React are JavaScript based Frameworks for creating modern web applications. Using React and Angular one can create a highly modular web app. So, you don’t need to go through a lot of changes in your code base for adding a new feature.Angular and React also allows you to create a native mobile application with the same JS, CSS & HTML knowledge.Best part – Open source library with highly active community support.4) Cloud Computing:This one is a veteran.Most other technologies on this list are alive only because of the proliferation of cloud computing.By allowing companies to save money, and users to simplify their computing needs, Cloud Computing is one of the most trending technologies that will stay popular in 2019, without a doubt.3) Augmented Reality and Virtual Reality:Virtual is real! VR and AR, the twin technologies that let you experience things in virtual, that are extremely close to real, are today being used by businesses of all sizes and shapes. But the underlying technology can be quite complex.Medical students use AR technology to practice surgery in a controlled environment.VR on the other hand, opens up newer avenues for gaming and interactive marketing.Whatever your interest might be, AR and VR are must-have skills if you want to ride the virtual wave!2) Blockchain:This is the tech that powers bitcoins, the whole new parallel currency that has taken over the world.Interestingly, blockchain as a technology has far-reaching potential in everything from healthcare to elections to real estate to law enforcement.Understand how blockchain works and your career is as sorted as the secure ledger this tech is based on!1) Artificial Intelligence (AI):AI existed even before the internet was born, but it is now that the data processing and compute power backbone became strong enough to sustain an entire technology by itself.AI is everywhere today, from your smartphones to your cars to your home to your banking establishment.It is the new normal, something the world cannot do without.Get your hands dirty with AI and have a crystal clear career ahead of you!
Why HTML is known as front-end language?
HTMLHypertext Markup Language is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets and scripting languages such as JavaScriptIt is the most basic building block of the Web. It defines the meaning and structure of web content.It is just one part or a piece of a web development. (You can say it as a one item in a recipe to prepare a big stuff like website!)How does it work?HTML consists of a series of short codes typed into a text-file by the site author — these are the tags. The text is then saved as a html file, and viewed through a browser, like Internet Explorer or Netscape Navigator. This browser reads the file and translates the text into a visible form, hopefully rendering the page as the author had intended. Writing your own HTML entails using tags correctly to create your vision. You can use anything from a rudimentary text-editor to a powerful graphical editor to create HTML pages. Simple example of HTML<!DOCTYPE> <html> <head> <title>Web page title</title> </head> <body> <h1>Write Your First Heading</h1> <p>Write Your First Paragraph.</p> </body> </html> HTML VersionsSince the time HTML was invented there are lots of HTML versions in market, the brief introduction about the HTML version is given below:HTML 1.0: The first version of HTML was 1.0, which was the barebones version of HTML language, and it was released in1991.HTML 2.0: This was the next version which was released in 1995, and it was standard language version for website design. HTML 2.0 was able to support extra features such as form-based file upload, form elements such as text box, option button, etc.
Internet of things
What is IoT?Internet of Things (IoT) is an ecosystem of connected physical objects that are accessible through the internet. The ‘thing’ in IoT could be a person with a heart monitor or an automobile with built-in-sensors, i.e. objects that have been assigned an IP address and have the ability to collect and transfer data over a network without manual assistance or intervention. The embedded technology in the objects helps them to interact with internal states or the external environment, which in turn affects the decisions taken.What is the scope of IoT?Internet of Things can connect devices embedded in various systems to the internet. When devices/objects can represent themselves digitally, they can be controlled from anywhere. The connectivity then helps us capture more data from more places, ensuring more ways of increasing efficiency and improving safety and IoT security.IoT is a transformational force that can help companies improve performance through IoT analytics and IoT Security to deliver better results. Businesses in the utilities, oil & gas, insurance, manufacturing, transportation, infrastructure and retail sectors can reap the benefits of IoT by making more informed decisions, aided by the torrent of interactional and transactional data at their disposal.How can IoT help?IoT platforms can help organizations reduce cost through improved process efficiency, asset utilization and productivity. With improved tracking of devices/objects using sensors and connectivity, they can benefit from real-time insights and analytics, which would help them make smarter decisions. The growth and convergence of data, processes and things on the internet would make such connections more relevant and important, creating more opportunities for people, businesses and industries.
Is it important to know programming to create a blog?
I am not a blogger and i dint know much about it. But yes you didn't want any programing language to learn to start blogging.This answer can be seem true to you when you think about those womens at home, who knows zero about programming but still has blogs and earn from it. you need small knowledge on google powerpoint, word, and wordpress.Programming knowledge is required when you want to build website from scratch. but wordpress builds the one for you!...Hope this would solve your doubt.
What is "program listing" in Java?
JAVA LIST INTERFACESome of the important points about Java List are:· List Interface is the sub interface of Collection. · It contains index-based methods to insert and delete elements. · It is an ordered collection of objects in which duplicate values can be stored. · Since List preserves the insertion order, it allows positional access and insertion of elements.· List Interface is implemented by ArrayList, LinkedList, Vector and Stack classes.· List allows you to add duplicate elements.· List allows you to have ‘null’ elements.· List indexes start from 0, just like arrays.1. List Interface declaration· public interface List<E> extends Collection<E> 2. Java List Example1. import java.util.*; 2. public class ListExample{ 3. public static void main(String args[]){ 4. List<String> al=new ArrayList<String>(); 5. al.add("Amit"); 6. al.add("Vijay"); 7. al.add("Kumar"); 8. al.add(1,"Sachin"); 9. System.out.println("An element at 2nd position: "+al.get(2)); 10. for(String s:al){ 11. System.out.println(s); 12. } 13. } 14. } Output: An element at 2nd position: Vijay Amit Sachin Vijay Kuma Java List MethodsSome of the useful Java List methods are;1. int size(): to get the number of elements in the list.2. boolean isEmpty(): to check if list is empty or not.3. boolean contains(Object o): Returns true if this list contains the specified element.4. Iterator<E> iterator(): Returns an iterator over the elements in this list in proper sequence.5. Object[] toArray(): Returns an array containing all of the elements in this list in proper sequence6. boolean add(E e): Appends the specified element to the end of this list.7. boolean remove(Object o): Removes the first occurrence of the specified element from this list.8. boolean retainAll(Collection<?> c): Retains only the elements in this list that are contained in the specified collection.9. void clear(): Removes all the elements from the list.10. E get(int index): Returns the element at the specified position in the list.11. E set(int index, E element): Replaces the element at the specified position in the list with the specified element.12. ListIterator<E> listIterator(): Returns a list iterator over the elements in the list.13. List<E> subList(int fromIndex, int toIndex): Returns a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive. The returned list is backed by this list, so non-structural changes in the returned list are reflected in this list, and vice-versa.Some of the default methods added to List in Java 8 are;1. default void replaceAll(UnaryOperator<E> operator): Replaces each element of this list with the result of applying the operator to that element.2. default void sort(Comparator<super E> c): Sorts this list according to the order induced by the specified Comparator.3. default Spliterator<E> spliterator(): Creates a Spliterator over the elements in this list.
Types of Operating System
Types of Operating System Operating systems are there from the very first computer generation and they keep evolving with time. In this chapter, we will discuss some of the important types of operating systems which are most commonly used.1) Batch operating systemThe users of a batch operating system do not interact with the computer directly. Each user prepares his job on an off-line device like punch cards and submits it to the computer operator. To speed up processing, jobs with similar needs are batched together and run as a group. The programmers leave their programs with the operator and the operator then sorts the programs with similar requirements into batches.The problems with Batch Systems are as follows −Lack of interaction between the user and the job.CPU is often idle, because the speed of the mechanical I/O devices is slower than the CPU.Difficult to provide the desired priority.2) Time-sharing operating systemsTime-sharing is a technique which enables many people, located at various terminals, to use a particular computer system at the same time. Time-sharing or multitasking is a logical extension of multiprogramming. Processor's time which is shared among multiple users simultaneously is termed as time-sharing.The main difference between Multiprogrammed Batch Systems and Time-Sharing Systems is that in case of Multiprogrammed batch systems, the objective is to maximize processor use, whereas in Time-Sharing Systems, the objective is to minimize response time.Multiple jobs are executed by the CPU by switching between them, but the switches occur so frequently. Thus, the user can receive an immediate response. For example, in a transaction processing, the processor executes each user program in a short burst or quantum of computation. That is, if nusers are present, then each user can get a time quantum. When the user submits the command, the response time is in few seconds at most.The operating system uses CPU scheduling and multiprogramming to provide each user with a small portion of a time. Computer systems that were designed primarily as batch systems have been modified to time-sharing systems.Advantages of Timesharing operating systems are as follows −Provides the advantage of quick response.Avoids duplication of software.Reduces CPU idle time.Disadvantages of Time-sharing operating systems are as follows −Problem of reliability.Question of security and integrity of user programs and data.Problem of data communication.3)Distributed operating SystemDistributed systems use multiple central processors to serve multiple real-time applications and multiple users. Data processing jobs are distributed among the processors accordingly.The processors communicate with one another through various communication lines (such as high-speed buses or telephone lines). These are referred as loosely coupled systems or distributed systems. Processors in a distributed system may vary in size and function. These processors are referred as sites, nodes, computers, and so on.The advantages of distributed systems are as follows −With resource sharing facility, a user at one site may be able to use the resources available at another.Speedup the exchange of data with one another via electronic mail.If one site fails in a distributed system, the remaining sites can potentially continue operating.Better service to the customers.Reduction of the load on the host computer.Reduction of delays in data processing.4) Network operating SystemA Network Operating System runs on a server and provides the server the capability to manage data, users, groups, security, applications, and other networking functions. The primary purpose of the network operating system is to allow shared file and printer access among multiple computers in a network, typically a local area network (LAN), a private network or to other networks.Examples of network operating systems include Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, Novell NetWare, and BSD.The advantages of network operating systems are as follows −Centralized servers are highly stable.Security is server managed.Upgrades to new technologies and hardware can be easily integrated into the system.Remote access to servers is possible from different locations and types of systems.The disadvantages of network operating systems are as follows −High cost of buying and running a server.Dependency on a central location for most operations.Regular maintenance and updates are required.5) Real Time operating SystemA real-time system is defined as a data processing system in which the time interval required to process and respond to inputs is so small that it controls the environment. The time taken by the system to respond to an input and display of required updated information is termed as the response time. So in this method, the response time is very less as compared to online processing.Real-time systems are used when there are rigid time requirements on the operation of a processor or the flow of data and real-time systems can be used as a control device in a dedicated application. A real-time operating system must have well-defined, fixed time constraints, otherwise the system will fail. For example, Scientific experiments, medical imaging systems, industrial control systems, weapon systems, robots, air traffic control systems, etc.There are two types of real-time operating systems.1.Hard real-time systemsHard real-time systems guarantee that critical tasks complete on time. In hard real-time systems, secondary storage is limited or missing and the data is stored in ROM. In these systems, virtual memory is almost never found.2.Soft real-time systemsSoft real-time systems are less restrictive. A critical real-time task gets priority over other tasks and retains the priority until it completes. Soft real-time systems have limited utility than hard real-time systems. For example, multimedia, virtual reality, Advanced Scientific Projects like undersea exploration and planetary rovers, etc.
