What is disruptive technology? – Definition from WhatIs.com

A disruptive technology is one that displaces an established technology and shakes up the industry or a ground-breaking product that creates a completely new industry.  

Harvard Business School professor Clayton M. Christensen coined the term disruptive technology. In his 1997 best-selling book, “The Innovator’s Dilemma,” Christensen separates new technology into two categories: sustaining and disruptive. Sustaining technology relies on incremental improvements to an already established technology. Disruptive technology lacks refinement, often has performance problems because it is new, appeals to a limited audience and may not yet have a proven practical application. (Such was the case with Alexander Graham Bell’s “electrical speech machine,” which we now call the telephone.)

Here are a few examples of disruptive technologies: 

  • The personal computer (PC) displaced the typewriter and forever changed the way we work and communicate.
  • The Windows operating system’s combination of affordability and a user-friendly interface was instrumental in the rapid

What is Web site? – Definition from WhatIs.com

This definition is also listed under presence, site and Website.

A Web site is a related collection of World Wide Web (WWW) files that includes a beginning file called a home page. A company or an individual tells you how to get to their Web site by giving you the address of their home page. From the home page, you can get to all the other pages on their site. For example, the Web site for IBM has the home page address of http://www.ibm.com. (The home page address actually includes a specific file name like index.html but, as in IBM’s case, when a standard default name is set up, users don’t have to enter the file name.) IBM’s home page address leads to thousands of pages. (But a Web site can also be just a few pages.)

Since site implies a geographic place, a Web site can be

What is computer? – Definition from WhatIs.com

A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program, software, or sequence of instructions on how the data is to be processed.

Complex computers include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer hardware (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today’s computers have both kinds of programming.

Major types of computers

Analog computer – represents data by measurable quantities
Desktop computer – a personal computer that fits on a desk and is often used for business or gaming
Digital computer – operates with numbers expressed as digits
Hybrid computer –
