what is the difference between a website and a web application

So what’s the difference between a website and a web application? Not a lot…or everything. It’s mostly a matter of perspective and semantics and is largely opinion based. Even if you wanted to ask Wikipedia (and who doesn’t?), you’d get definitions for a web application and a website that sound awfully similar. http://www.seguetech.com/website-vs-web-application-whats-the-difference/

A website is informational

A web application is interactive

What is a Web Portal

A Web portal is a specially designed website that often serves as the single point of access for information. It can also be considered a library of personalized and categorized content. A Web portal helps in search navigation, personalization, notification and information integration, and often provides features like task management, collaboration, and business intelligence and application integration.https://www.techopedia.com/definition/17352/web-portal

Web portals are also known simply as portals

what is web 1.0, web 2.0 and web 3.0


Web 1.0

It is the “readable” phrase of the World Wide Web with flat data. In Web 1.0, there is only limited interaction between sites and web users. Web 1.0 is simply an information portal where users passively receive information without being given the opportunity to post reviews, comments, and feedback.

Web 2.0

It is the “writable” phrase of the World Wide Web with interactive data. Unlike Web 1.0, Web 2.0 facilitates interaction between web users and sites, so it allows users to interact more freely with each other. Web 2.0 encourages participation, collaboration, and information sharing. Examples of Web 2.0 applications are Youtube, Wiki, Flickr, Facebook, and so on.

Web 3.0

It is the “executable” phrase of Word Wide Web with dynamic applications, interactive services, and “machine-to-machine” interaction. Web 3.0 is a semantic web which refers to the future. In Web 3.0, computers can interpret information like humans and intelligently generate and distribute useful content tailored to the needs of users. One example of Web 3.0 is Tivo, a digital video recorder. Its recording program can search the web and read what it finds to you based on your preferences.

What is a web based application?


What is a web based application? A web based application is a software package that can be accessed through the web browser. The software and database reside on a central server rather than being installed on the desktop system and is accessed over a network.

What is Cloud computing and how is it changing IT?


Cloud computing, software services, outsourcing and hosting mean very different things, but to IT managers and administrators, these technologies are all about the same thing: applications and/or data formerly on-premise are now on a server beyond the company perimeter. There is plenty of trepidation among established shops who are in a familiar (if not irritating) groove. How much disruption will this emerging computing model cause in the average enterprise? This special report digs into strategic areas of cloud computing where IT pros are short on answers.

What is the difference between an Intranet and an Extranet?

An extranet is basically a private network designed specifically to allow these individuals (clients, vendors, suppliers, partners, etc.) to communicate with you and your employees in a closed virtual space. Extranets serve an extremely important role, as they allow for private communication, collaboration, knowledge sharing, document sharing, and data transfer between organizations.

An intranet is a network where employees can create content, communicate, collaborate, get stuff done, and develop the company culture.

Why are web applications and storage not totally secure?


Most web applications have a need to store sensitive information, either in a database or on a file system somewhere. The information might be passwords, credit card numbers, account records, or proprietary information. Frequently, encryption techniques are used to protect this sensitive information. While encryption has become relatively easy to implement and use, developers still frequently make mistakes while integrating it into a web application. Developers may overestimate the protection gained by using encryption and not be as careful in securing other aspects of the site.

A few areas where mistakes are commonly made include:

  • Failure to encrypt critical data
  • Insecure storage of keys, certificates, and passwords
  • Improper storage of secrets in memory
  • Poor sources of randomness
  • Poor choice of algorithm
  • Attempting to invent a new encryption algorithm
  • Failure to include support for encryption key changes and other required maintenance procedures

What IT jobs will disappear?


  • Programers
  • Web page designers
  • Database administrators
  • network administrators
