Fog Computing Is A New Concept Of Data Distribution? For the last couple of years there have hardly been any new concepts in cloud computing. But hardly doesn’t mean never. Since the summer of 2013 you might have noticed the appearance of a new trend that has been called Fog Computing . The main purpose of fog computing is to gather services, applications, large data volumes in one place and unite them with the networks of a new generation. The aim is to offer data, computing power, memory and services at a really distributed level. The thing is that today’s data is extremely dispersed and delivered continuously, in large volumes and to a large number of users with different devices. In order to make an effective cloud model, businesses need to learn how to deliver the content to their users via geographically distributed platforms and not via the cloud which is placed in one place. The idea of fog computing is to distribute all data and place it closer to a use

 What is DTMF? It is acronym for Dual Tone Multi-Frequency , also known as Touch Tone. It is a method, used by the telephone system to communicate the pressed keys when dialing. Each key represents a digit or a character and generates two distinct tones - a high frequency tone and a low frequency tone – when pressed. DTMF allows navigation of voice menus and other advanced calling services. It is also used for control purposes, such as an automatic bill-paying service, or remote control of appliances, such as a telephone answering machine. DTMF tones are sometimes used in caller ID systems to transfer the caller ID information [1]. How Does the DTMF work? The DTMF has a keypad which is laid out in a 4×4 matrix in which each row represents a low frequency and each column represents a high frequency [2]. Here are the signals you send when you press your Touch-tone phone keys [3]: DTMF low and high frequency   Row and Column Keypad When you press the buttons

Accessing a JSP page could be considered the same as accessing a Web service. If you think about it, calling a JSP page is a large method packaged in the form of a servlet, which sends back character output. The biggest difference is in the packaging. A Web service defines an interface through which it's possible to define exactly the data being sent to and from the Web service.  The JSP page, on the other hand, just hands back a large character text stream in the HTTP wrapper. This makes it hard to parse a JSP result for finer work. This makes a Web service easier to use programmatically over a straight JSP page. Whenever fine control of the data being sent over a HTTP request is required, it is time to use a Web service. The next fact to consider is state. One thing JSP and servlets give the programmer is a concept of state: application, session, page, and so on. A service isn't as tied to the concept of state. In fact, keeping a Web service stateless

What is Multitenancy? Multitenancy is an architecture in which a single instance of a software application serves multiple customers. It gives the ability to use the same software and interfaces to configure resources and it isolates customer-specific traffic and data. Each customer is called a tenant. Tenants may be given the ability to configure some parts of the application, such as color of the user interface ( UI ) or business rules , but they cannot change the application's code . This means that although tenants are using the same building blocks in their configuration, the appearance or workflow of the application may be different for two tenants. Also, the Service Level Agreement (SLA) of each tenant can differ [1]. Multitenancy vs. Singletenancy: Multitenancy can be economical because software development and maintenance costs are shared. It can be contrasted with single-tenancy, an architecture in which each customer has their own software instance and

In this Lesson we will create a form page " form.jsp " that takes the user email. After that we will check the user existence in our DB. If the user email stored in the DB, a welcoming page will be opened to him/her. If the user is a new user then a message will be displayed that tells him/her this email is not stored in our DB. Note: I use access 2013 database and Eclipse Juno     Basic step, Create a new project: Open Eclipse then click on File > New > Other > Web > Dynamic Web Project. First, Load the DB class: In this step we will connect with database so we will gather all its code in a java class named " DBConnection.java " under a package called " code ". Expand your project then right click on java resources > New > Package . After-that Give a name for your package ex, code   Right click on your created new package that called code > New > Class.   After-that Give a name for your Class ex, DBConnection.
