Arduino-Application of IoT An era is about to exist around us where ubiquity will exist everywhere. This means that "users" of internet will increase to billions where humans may become a minority as generators and receivers of traffic but most of the internet traffic will contain devices and all kinds of things" thereby creating a much wider and more complex Internet of Things. IoT increases efficiency and productivity and we have a smart or even very unusual example of IoT application is a smart toothbrush.  IoT based objects or devices observes and understand the situation and then performs the required task without human intervention. Now a question arises that how this comes possible that devices does all these things by themselves and the answer is a combination of software and hardware. One example of the technology to implement the concept of IoT is Arduino. Before knowing Arduino, we need to know What is Microcontroller? As we all know that programmers work in v

If we talk about internet, technology, network demand, applications then we will definitely come to a point in our discussion i.e. IoT. As technology is growing, the demand for internet application development is also growing and IoT plays a vital role in developing such applications. IoT stands for Internet of Things. It is an Internet technology connecting devices, machines and tools to the internet by means of wireless technologies. Over 9 billions 'things' connected to the internet as of now and also 'things' connected to the internet are expected to rise beyond 20 billion in near future. IoT is influencing our lifestyle from the way we react to the way we behave. From the Air conditioners that you can control from your smartphones to the smart cars providing the shortest routes or your smart watches which is tracking your daily routine.  What is IoT? IoT is known as Internet of Things which means things and connected to each other and communicating with each other

The difference between a Service Level Agreement (SLA) and an Operational Level Agreement (OLA) is what the IT organization as a whole is promising to the customer (SLA), and what the functional IT groups promise to each other (OLA). The SLA can state that "IT will ensure that computer equipment will be maintained". Of course that statement is a generalization that cannot be measured, so perhaps a better statement would be "There will be less than 80 lost man-hours per year due to lack of computer equipment maintenance". or  SLA's are generally an agreement between the IT department/provider and the business, to provide a particular level of service. OLA's are usually agreements between different areas of the IT department/providers, often to provide a particular SLA. For example we can say that,  For an organisation may have a particular SLA that states no more than 100 minutes downtime per quarter. For the IT department to adhere to this, the

When the data started moving towards its unstructured form to the structured one and people started moving towards many computers from single computer with heavy configuration (commodity hardware), the need arose for the technology to evolve. Now firstly we shall understand about which unstructured data are we talking about? So the answer to the question is Big data . Let's understand a little about Big data first. Big data refers to data sets that are too large or complex for traditional data-processing application software to adequately deal with. Data with many cases (rows) offer greater statistical power, while data with higher complexity (more attributes or columns) may lead to a higher false discovery rate. Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating, information privacy and data source. Big data was originally associated with three key concepts: volume, variety, and velocity . Other con
